Summary

Migrates every web provider (search + extract + crawl) out of tools/web_tools.py into the bundled-plugin architecture, matching the image_gen template. All seven providers now live under plugins/web/<vendor>/, registering through agent.web_search_registry instead of hardcoded if backend == ... chains in the dispatcher.

This unblocks user-added web providers (drop a directory under ~/.hermes/plugins/web/ and they appear in hermes tools automatically — same UX as image_gen / spotify / google_meet plugins).

Scope — what moved

Provider Capabilities Async extract? Async crawl? Auth
brave-free search sync BRAVE_SEARCH_API_KEY
ddgs search sync none (pip ddgs)
searxng search sync SEARXNG_URL
exa search + extract sync EXA_API_KEY
parallel search + extract async PARALLEL_API_KEY
tavily search + extract + crawl sync sync TAVILY_API_KEY
firecrawl search + extract + crawl async async direct (FIRECRAWL_API_KEY / FIRECRAWL_API_URL) or Nous Tool Gateway

Each plugin is plugins/web/<vendor>/{plugin.yaml,__init__.py,provider.py}.

What changes for users

Nothing. The setup wizard, hermes tools picker, and per-provider env vars all behave identically. The PR is a pure refactor preserving the legacy response shapes bit-for-bit. The only visible difference is that user-installed web plugins now light up in the picker the same way image_gen plugins do.

Architecture

Before:

  • 9 hardcoded TOOL_CATEGORIES["web"] rows in hermes_cli/tools_config.py
  • Per-vendor inline helpers in tools/web_tools.py (_get_firecrawl_client, _tavily_request, _parallel_search, etc. — ~600 LoC)
  • Per-vendor if backend == "exa": ... elif backend == "tavily": ... chains in all three dispatchers
  • Legacy in-tree ABCs at tools/web_providers/base.py

After:

  • 2 hardcoded TOOL_CATEGORIES["web"] rows ("Nous Subscription", "Firecrawl Self-Hosted" — the two non-provider UX setup flows for firecrawl); the other 7 come from _plugin_web_search_providers()
  • All vendor code lives in plugins/web/<vendor>/provider.py
  • Each dispatcher is a single registry lookup + inspect.iscoroutinefunction async/sync detection
  • One ABC at agent/web_search_provider.py with supports_search/extract/crawl capability flags

Registry resolution semantics (Option B — conservative smart fallback)

_resolve() in agent/web_search_registry.py follows three rules in order:

  1. Explicit config wins, ignoring availability. If web.<capability>_backend (or web.backend) names a registered + capable provider, return it — even if is_available() is False. The dispatcher then surfaces a precise "X_API_KEY is not set" error instead of silently switching backends.
  2. Single-provider shortcut. When only one registered provider matches the capability and is available, pick it.
  3. Legacy preference walk, filtered by availability. Walk _LEGACY_PREFERENCE (firecrawl → parallel → tavily → exa → searxng → brave-free → ddgs) and pick the first one that's capable AND available. Matches the historic tools.web_tools._get_backend() candidate order so installs that never set a config key keep landing on the same provider they did before the plugin migration.

When the configured name is registered but capability-incompatible (e.g. web.extract_backend: brave-free), the dispatcher surfaces a typed "X is a search-only backend and cannot extract URL content" error matching the legacy wording.

Async-or-sync extract dispatch

parallel and firecrawl declare async def extract(); exa and tavily are sync. The dispatcher detects via inspect.iscoroutinefunction(provider.extract) and either awaits the result or runs the sync call in asyncio.to_thread(...) so the gateway event loop is never blocked.

Backward compatibility

The names in tools.web_tools.* that tests/integration code reaches for are preserved as re-export shims from the plugins:

  • Firecrawl (lazy proxy), check_firecrawl_api_key, _get_firecrawl_client, _is_tool_gateway_ready, _has_direct_firecrawl_config, _get_direct_firecrawl_config, _get_firecrawl_gateway_url, _firecrawl_backend_help_suffix, _raise_web_backend_configuration_error, _extract_web_search_results, _extract_scrape_payload, _to_plain_object, _normalize_result_list
  • _tavily_request, _normalize_tavily_search_results, _normalize_tavily_documents
  • _get_parallel_client, _get_async_parallel_client, _get_exa_client
  • The cached client globals (_firecrawl_client, _parallel_client, _async_parallel_client, _exa_client) live on tools.web_tools so unit tests that reset them between cases keep working

The plugin implementations use import tools.web_tools as _wt indirection to read helpers like _wt._read_nous_access_token, _wt.Firecrawl, _wt.prefers_gateway so test patches that target the legacy paths reach the plugin code transparently.

Diff stat

39 files changed, 3459 insertions(+), 1534 deletions(-)

The big wins:

  • tools/web_tools.py: 2227 → 1511 lines (−716 lines / −32%)
  • tools/web_providers/ directory deleted entirely (−168 lines)
  • hermes_cli/tools_config.py: 7 hardcoded provider rows removed (−91 lines)

The added lines are split roughly: 60% new plugin code (one provider.py per vendor, ranges from ~90 lines for brave-free to ~750 lines for firecrawl which now also handles crawl), 25% new tests (tests/plugins/web/test_web_search_provider_plugins.py = 472 lines, 45 tests), 15% new ABC + registry + plugin glue (agent/web_search_provider.py + agent/web_search_registry.py + hermes_cli/plugins.py web context hook).

Testing

210/210 plugin + dispatcher tests pass (208 original + 2 new regression tests from behavior-parity verification):

  • tests/tools/test_web_providers.py (ABC contract — rewritten to test the new unified ABC)
  • tests/tools/test_web_providers_brave_free.py / _ddgs.py / _searxng.py
  • tests/tools/test_web_tools_config.py (backend selection, client config, error responses)
  • tests/tools/test_web_tools_tavily.py
  • tests/tools/test_website_policy.py (per-URL gate + redirect re-check)
  • tests/tools/test_config_null_guard.py
  • tests/plugins/web/test_web_search_provider_plugins.py (45 new tests covering ABC, registry, async detection, error shapes)

Plugin test classes (45 tests):

  • TestBundledPluginsRegister (16) — all seven plugins register, capability flags correct, picker schema valid
  • TestIsAvailable (7) — every plugin's is_available() correctly reflects env-var presence
  • TestRegistryResolution (4) — explicit-config-wins-when-unavailable, typo-falls-back, capability-incompatible-falls-back, no-config behavior
  • TestAsyncExtractDispatch (4) — inspect.iscoroutinefunction correctly distinguishes parallel/firecrawl (async) from exa/tavily (sync)
  • TestErrorResponseShapes (8) — plugins return typed error dicts when credentials are missing, never raise (including the new firecrawl crawl error test)

Full tests/tools/ regression sweep: 4910 passed, 44 skipped, 0 failures.

Behavior-parity verification (local E2E)

To make sure the plugin migration is a pure refactor, the three dispatchers were exercised in subprocesses pinned to (a) origin/main and (b) this PR's worktree, with all web-provider credentials cleared, across 14 config scenarios (no-config, plus every search_backend / extract_backend / crawl_backend override for each registered provider). For each scenario the JSON envelope shape is reduced to {success, has_error_top, has_data, n_results, per_result_has_error, error_category} and compared.

Initial run surfaced two observable behavior changes from the migration, both fixed in commit af2a7bfe6:

  1. web_search_tool on an unconfigured system. Main returns {"error": "Error searching web: Web tools are not configured..."} (via tool_error(), no success key). The migrated dispatcher was returning {"success": False, "error": "Web tools are not configured..."} because firecrawl.search() was catching ValueError from _get_firecrawl_client() itself instead of letting it propagate. Fix: pull _get_firecrawl_client() out of the broad try in the plugin's search(). Pre-flight errors propagate to the dispatcher's top-level except handler, matching main's legacy envelope. In-flight SDK errors still get wrapped per-result.

  2. web_crawl_tool on an unconfigured system. Main short-circuits on check_firecrawl_api_key() with {"success": False, "error": "web_crawl requires Firecrawl..."} at the top level. The migrated dispatcher was returning {"results": [{"url": "...", "error": "Web tools are not configured..."}]} — the firecrawl plugin's crawl() except ValueError was wrapping the pre-flight error as a per-page failure inside results[]. Models that check result.get("error") would miss the failure. Fix: mirror main's upstream availability gate in the dispatcher — when the resolved crawl provider is is_available()==False, short-circuit BEFORE delegating to the plugin with the same top-level error shape main emits.

Two regression tests in tests/tools/test_web_providers.py::TestUnconfiguredErrorEnvelopeParity lock the new behavior in so future plugin work can't re-introduce per-result error wrapping on pre-flight config errors.

Final state: 14/14 dispatcher scenarios match origin/main shape exactly. Plugin/dispatcher tests now 210/210 (208 + 2 new regression tests).

Self-review fix (commit 0dec60f7a)

Catches up the registry's _LEGACY_PREFERENCE order with the legacy tools.web_tools._get_backend() candidate tuple so direct callers of agent.web_search_registry.get_active_*_provider() (no _get_backend() interpose) don't return None for users who have credentials but no explicit web.backend config key. Verified empirically: TAVILY+EXA → tavily; EXA+PARALLEL → parallel; BRAVE+FIRECRAWL → firecrawl, all matching main. Plus four stale-docstring cleanups (crawl claims, ABC capabilities, registry comment block) and the removal of three dead plugin-level cache globals + their no-op reset helpers (rewritten to clear the canonical _wt._<name> slots, matching the pattern exa already used correctly).

Out of scope (clean follow-ups)

  af2a7bf  fix(web): preserve top-level error envelope on unconfigured systems

Adds plugins/web/brave_free/ as the first plugin built against the new
WebSearchProvider ABC. Mirrors the plugins/image_gen/openai/ layout exactly:

  plugins/web/brave_free/
    plugin.yaml      kind: backend, provides_web_providers: [brave-free]
    __init__.py      register(ctx) -> ctx.register_web_search_provider(...)
    provider.py      BraveFreeWebSearchProvider(WebSearchProvider)

Behavior preserved: same name ("brave-free" with hyphen), same env var
(BRAVE_SEARCH_API_KEY), same HTTP request shape, same response normalization.

The legacy tools/web_providers/brave_free.py is left in place — the
dispatcher in tools/web_tools.py still references it. Task 7 cuts over the
dispatcher to the new registry; Task 10 deletes the legacy file.

Adds plugins/web/ddgs/ following the same plugins/image_gen/ pattern as
brave_free. DuckDuckGo search via the community ddgs package; no API key,
package is an optional dep gated by is_available().

E2E verified — registry now has ['brave-free', 'ddgs'].
Adds plugins/web/searxng/. SearXNG aggregates results from upstream engines
via its JSON API (/search?format=json) — search-only, no extract capability
(supports_extract() returns False).

E2E verified — registry now has ['brave-free', 'ddgs', 'searxng'].
The three migrated providers (brave-free, ddgs, searxng) are now dispatched
through agent.web_search_registry.get_provider() instead of importing
their concrete classes directly. The four inline providers (parallel, exa,
tavily, firecrawl) keep their existing branches — they live in
tools/web_tools.py itself and aren't part of this spike's plugin extraction.

The legacy tools/web_providers/{brave_free,ddgs,searxng}.py modules are
still in place (untouched by this commit) — Task 10 deletes them once the
real migration PR is ready. Keeping them alive during the spike means
revertibility is trivial.

E2E verified:
  1. Plugin discovery registers ['brave-free','ddgs','searxng']
  2. Config web.search_backend: brave-free resolves to the plugin instance
  3. Dispatch result matches the original {success, data.web[]} contract
  4. compile OK; no new LSP errors beyond pre-existing ones in web_tools.py
Adds _plugin_web_search_providers() and wires it into _visible_providers()
for the "Web Search & Extract" category. Mirrors the existing image_gen
pattern at the same site exactly.

Spike scope: while the three migrated providers (brave-free, ddgs, searxng)
still have hardcoded TOOL_CATEGORIES rows, _WEB_PLUGIN_SKIPLIST excludes
them so the picker doesn't show duplicates. The migration PR drops the
hardcoded rows and the skip-list both — then this helper is the only
source of web-provider picker rows.

E2E verified: helper returns [] today (skip-list covers all 3 migrated
providers); injection point is sound and ready for the post-migration state.
Deletes tools/web_providers/{brave_free,ddgs,searxng}.py — the three
providers that moved to plugins/web/ in prior commits. tools/web_tools.py
no longer imports them (registry dispatch as of d873596), so removing
them is purely a cleanup pass.

Also migrates the existing tests to the new import paths:
  tests/tools/test_web_providers_brave_free.py
  tests/tools/test_web_providers_ddgs.py
  tests/tools/test_web_providers_searxng.py

Mechanical rewrites:
  - `from tools.web_providers.X import YSearchProvider`
      -> `from plugins.web.X.provider import YWebSearchProvider`
  - `.is_configured()` -> `.is_available()`        (legacy method  -> new method)
  - `.provider_name()` -> `.name`                  (legacy method  -> new property)
  - `from tools.web_providers.base import WebSearchProvider`
      -> `from agent.web_search_provider import WebSearchProvider`
      (the subclass-check asserts membership in the new plugin-facing ABC)
  - `sys.modules.delitem("tools.web_providers.ddgs")` updated to point at
    `plugins.web.ddgs.provider` (cache-busting for lazy ddgs imports)

The TestXBackendWiring / TestXSearchOnlyErrors classes (covering
_is_backend_available, _get_backend, check_web_api_key, and the
"search-only" error paths in web_extract/web_crawl) are untouched —
those still test web_tools.py's backend-selection logic, which continues
to recognize the names "brave-free" / "ddgs" / "searxng" even after the
modules behind them moved to plugins.

tools/web_providers/base.py is intentionally NOT deleted by this commit
— it's the parent ABC of the legacy modules and shares its name with
agent/web_search_provider.py::WebSearchProvider. Removing it surfaces the
naming collision (see PR description Finding 0); the real migration PR
deletes it in the same commit that drops the _WEB_PLUGIN_SKIPLIST
guards in hermes_cli/tools_config.py.

Test results:
  bash scripts/run_tests.sh tests/tools/test_web_providers_*.py
  -> 65 passed in 3.41s (all rewritten unit tests + unchanged integration tests)
  bash scripts/run_tests.sh tests/tools/test_web_*.py
  -> 141 passed in 4.70s (full web test set, post-deletion)
…registries

Both web_search_registry._resolve() and image_gen_registry.get_active_provider()
walked their registered providers and returned the first one matching the
capability flag — without checking whether that provider was actually
usable. On a fresh install with no credentials at all, this meant
get_active_search_provider() returned `brave-free` (legacy preference
order) even though BRAVE_SEARCH_API_KEY was unset, leading the
dispatcher to surface a "BRAVE_SEARCH_API_KEY is not set" error for a
provider the user never chose. Same bug shape in image_gen for FAL.

Resolution semantics now match tools.web_tools._get_backend():

  1. Explicit config name wins, ignoring is_available() — the dispatcher
     surfaces a precise "X_API_KEY is not set" error rather than silently
     switching backends. Matches user expectation: "I configured X, tell
     me what's wrong with X."
  2. Fallback (no explicit config) walks the legacy preference order
     filtered by is_available() — pick the highest-priority backend the
     user actually has credentials for.

is_available() is wrapped in a try/except so a buggy provider doesn't
brick resolution.

E2E verified:
  - No creds + no config: get_active_search_provider() -> None
  - Explicit brave-free + no key: get_active_search_provider() -> brave-free
    (and .is_available() correctly reports False)

This fix was identified during the spike (NousResearch#25182 finding #1) and is
fold-in to the same PR rather than a follow-up.
Two ABC additions to cover the surface area of the remaining four
providers (exa, parallel, tavily, firecrawl) which were untouched by the
initial spike:

1. supports_crawl() + crawl() — Tavily natively crawls a seed URL via
   its /crawl endpoint. Exposing supports_crawl=True lets the crawl
   tool's dispatcher route to Tavily when configured, falling back to
   the auxiliary-model summarization path otherwise. Firecrawl could
   add this in a follow-up (the SDK supports it; we just don't surface
   it as a tool today).

2. Async-or-sync extract() — Parallel's SDK is natively async
   (AsyncParallel.beta.extract); Exa and Tavily are sync; Firecrawl is
   sync but called inside asyncio.to_thread() with a 60s timeout. The
   ABC docstring now permits either shape: implementations declare
   their own sync/async signature and the dispatcher uses
   inspect.iscoroutinefunction to detect and await.

Also adds get_active_crawl_provider() to web_search_registry mirroring
the search/extract resolvers, with web.crawl_backend as the explicit
override config key.

No behavior change on its own — these are scaffolds for the four
remaining provider migrations.

…tract)

Migrates Exa from the inline `_exa_search()` / `_exa_extract()` helpers in
tools/web_tools.py to a bundled plugin at plugins/web/exa/.

This is the first plugin in this PR to advertise supports_extract=True,
exercising the multi-capability ABC path that the initial three migrations
(brave_free, ddgs, searxng — all search-only) did not cover.

Both Exa methods are sync — the SDK is sync-only. The web_extract_tool
dispatcher in tools/web_tools.py will continue to call them inline until
Task "dispatch-extract-all" cuts it over to the registry.

Behaviour preserved bit-for-bit aside from the ABC method-name change:
  - is_configured()  -> is_available()
  - provider_name()  -> name (property)
  - "exa" stays as the registered name
  - Module-level `_exa_client` cache + lazy `from exa_py import Exa`
    preserved at the new location.
  - Errors (ValueError for missing API key, ImportError for missing SDK,
    generic Exception) caught and surfaced as {"success": False, "error": ...}
    instead of raising.

Adds "exa" to _WEB_PLUGIN_SKIPLIST in hermes_cli/tools_config.py so the
hardcoded TOOL_CATEGORIES["web"] row and the plugin-injected row don't
duplicate during the spike. The skip-list goes away in the cleanup phase
along with the hardcoded row.

The legacy inline `_exa_search` / `_exa_extract` / `_get_exa_client` /
`_exa_client` in tools/web_tools.py are NOT deleted yet — the dispatcher
still references them. They go away in the next dispatcher-cutover commit.

E2E verified:
  - Plugin discovers + registers
  - .supports_search/.supports_extract/.supports_crawl = (True, True, False)
  - .get_setup_schema() returns the picker row shape
  - resolve(): explicit exa + EXA_API_KEY -> exa; without key -> exa (registered
    but unavailable, dispatcher surfaces "EXA_API_KEY not set" error)
Migrates Parallel.ai from inline `_parallel_search()` / `_parallel_extract()`
in tools/web_tools.py to a bundled plugin at plugins/web/parallel/.

First plugin in the codebase to expose an async :meth:`extract`:

  - search() is sync — Parallel.beta.search
  - extract() is **async def** — AsyncParallel.beta.extract

The ABC's docstring on supports_extract() already permits sync-or-async;
this commit is the first to exercise the async path. The web_extract_tool
dispatcher (next commit) detects coroutines via
inspect.iscoroutinefunction and awaits accordingly.

Behavior preserved:
  - PARALLEL_API_KEY required (raises ValueError if missing → surfaced
    as {"success": False, "error": "..."} instead)
  - PARALLEL_SEARCH_MODE env var honored (agentic|fast|one-shot, default
    agentic), validated via _resolve_search_mode()
  - Limit capped at 20 server-side via min(limit, 20)
  - Per-URL failure mode preserved: response.errors[] each become a
    result dict with an "error" field rather than raising
  - Module-level _parallel_client / _async_parallel_client caches kept
    (mirrors legacy singleton pattern)

Adds "parallel" to _WEB_PLUGIN_SKIPLIST in hermes_cli/tools_config.py so
the picker doesn't double-list.

The legacy inline _parallel_search, _parallel_extract, _get_parallel_client,
_get_async_parallel_client in tools/web_tools.py are NOT deleted yet — the
dispatcher still calls them. They go away when the dispatcher cuts over.

E2E verified:
  - inspect.iscoroutinefunction(p.search) -> False
  - inspect.iscoroutinefunction(p.extract) -> True
  - extract() returns a coroutine (not a list)
  - 5 providers register correctly (brave-free, ddgs, exa, parallel, searxng)
…tract + crawl)

Migrates Tavily from inline _tavily_request() / _normalize_tavily_*
helpers in tools/web_tools.py to a bundled plugin at plugins/web/tavily/.

First plugin in the codebase to advertise supports_crawl=True. Tavily is
unique among built-in backends in offering a native /crawl endpoint that
walks linked pages from a seed URL with optional natural-language
instructions and depth ("basic" or "advanced").

Capabilities:
  - supports_search()  -> True (Tavily /search)
  - supports_extract() -> True (Tavily /extract)
  - supports_crawl()   -> True (Tavily /crawl)
  All sync (httpx.post under the hood).

The crawl method accepts forward-compat kwargs (instructions, depth,
limit) and is gated against unsafe URLs/policy by the dispatcher in
web_crawl_tool — exactly as before.

Behavior preserved:
  - TAVILY_API_KEY required (ValueError → typed error response)
  - TAVILY_BASE_URL env override honored
  - /crawl requires both body auth AND Bearer header — preserved
  - failed_results[] and failed_urls[] response keys mapped to per-URL
    items with error fields rather than raising
  - max_results capped at 20 server-side

Adds "tavily" to _WEB_PLUGIN_SKIPLIST.

The legacy inline _tavily_request / _normalize_tavily_search_results /
_normalize_tavily_documents / _TAVILY_BASE_URL in tools/web_tools.py are
NOT deleted yet — search/extract dispatch and the entire web_crawl_tool
function still reference them. They go away when those dispatchers are
cut over to the registry.

E2E verified:
  - Tavily registers with all 3 capabilities
  - Provider list now: brave-free, ddgs, exa, parallel, searxng, tavily
…ct + dual auth)

Migrates Firecrawl from inline code in tools/web_tools.py to a bundled
plugin at plugins/web/firecrawl/. By line count this is the largest of
the seven provider migrations: the firecrawl path captured most of the
file's vendor-specific complexity.

What moved into the plugin (all previously in tools/web_tools.py):

  Lazy Firecrawl SDK proxy
    - _load_firecrawl_cls() — caches the imported SDK class
    - _FirecrawlProxy + Firecrawl singleton — defers ~200ms of SDK
      imports until first construction or isinstance check.

  Client construction (dual auth)
    - _get_direct_firecrawl_config()  — direct FIRECRAWL_API_KEY/URL path
    - _get_firecrawl_gateway_url()    — managed Nous tool-gateway URL
    - _is_tool_gateway_ready()        — gateway URL + Nous token check
    - _has_direct_firecrawl_config()  — direct config present?
    - _get_firecrawl_client()         — combined client construction
                                        honoring web.use_gateway
    - check_firecrawl_api_key()       — top-level "is firecrawl usable"
    - _firecrawl_backend_help_suffix() — managed-gateway help string
    - _raise_web_backend_configuration_error() — typed misconfig error

  Response shape normalization (vendor-specific)
    - _to_plain_object(), _normalize_result_list() — SDK→dict helpers
    - _extract_web_search_results() — handles SDK/direct/gateway shapes
    - _extract_scrape_payload()     — nested-data unwrap for scrape

  Per-URL extract loop
    - 60s asyncio.wait_for timeout per URL
    - Pre-scrape website-policy gate
    - Post-scrape redirect-aware SSRF re-check
    - Format-aware content selection (markdown / html / auto)
    - Per-URL errors returned as {"error": str} entries, no raises

Extract is declared `async def` — each URL is scraped in
asyncio.to_thread(...). This is the second async-extract plugin after
parallel.

The plugin re-exports `Firecrawl` (the lazy proxy) and
`check_firecrawl_api_key()` so existing tests doing
`patch("tools.web_tools.Firecrawl")` or
`monkeypatch.setattr(web_tools, "check_firecrawl_api_key", ...)` keep
working — tools/web_tools.py re-exports both names in the next
dispatcher-cutover commit.

Note: web_crawl_tool still has its own Firecrawl crawl path inline
(separate from extract); the Firecrawl SDK supports /crawl but we don't
expose supports_crawl=True on this plugin yet. Tavily handles crawl
today. Adding Firecrawl crawl is a clean follow-up.

Adds "firecrawl" to _WEB_PLUGIN_SKIPLIST.

E2E verified:
  - All 7 providers register: brave-free, ddgs, exa, firecrawl,
    parallel, searxng, tavily
  - inspect.iscoroutinefunction(firecrawl.extract) -> True
  - Firecrawl proxy is a callable lazy proxy at module level
  - check_firecrawl_api_key reflects FIRECRAWL_API_KEY presence
Cuts over web_search_tool, web_extract_tool, and web_crawl_tool in
tools/web_tools.py to dispatch through agent.web_search_registry
instead of the legacy hardcoded if-elif backend chains.

Per-tool changes:

  web_search_tool (sync)
    Replace 5 backend branches (parallel, exa, registry-3-providers,
    tavily, firecrawl-fallthrough) with a single registry path:
      1. _get_search_backend() resolves the configured name
      2. _wsp_get_provider(name) for explicit-config-wins semantics
      3. get_active_search_provider() fallback for typo / unknown name
      4. provider.search(query, limit) — sync for all 7 providers

  web_extract_tool (async)
    Replace 4 backend branches (parallel-async, exa-sync, tavily-sync,
    search-only-error, firecrawl-perurl-loop) with:
      1. Same provider resolution as search.
      2. When configured backend IS registered but doesn't support
         extract (search-only providers like brave-free), surface a
         typed "search-only" error matching the legacy text — tests
         assert that wording.
      3. inspect.iscoroutinefunction(provider.extract) detects sync vs
         async: parallel + firecrawl are async; exa + tavily are sync.
         Sync extracts run in asyncio.to_thread() so we don't block.

  web_crawl_tool (async)
    Replace tavily-specific branch + search-only-error block with:
      1. _wsp_get_provider(backend) — explicit config first
      2. Search-only typed error when the configured name doesn't
         support crawl (matches legacy phrasing)
      3. get_active_crawl_provider() fallback otherwise
      4. provider.crawl(url, **kwargs) — async-or-sync dispatch as above
      5. Response post-processing (LLM summarization, trimming) stays
         unchanged — it's not provider-specific.
    When no plugin advertises supports_crawl, falls through to the
    existing Firecrawl-via-web-summarize path below (unchanged).

Test updates (2 tests in tests/tools/test_web_tools_config.py):
  - test_web_search_clamps_limit_before_backend_call:
      patch("tools.web_tools._parallel_search") -> patch the registry
      provider returned by agent.web_search_registry.get_provider
  - test_search_error_response_does_not_expose_diagnostics:
      patch("tools.web_tools._get_firecrawl_client") -> same pattern

Tests unchanged (still pass):
  - All TestXBackendWiring classes (test _get_backend / _is_backend_available
    config-resolution, independent of dispatch)
  - All TestXSearchOnlyErrors classes (test the search-only error path
    via web_extract_tool / web_crawl_tool — error text preserved)
  - 141 passing web tests total, 0 regressions.

Dead-code cleanup deferred to a follow-up commit so this diff stays
focused on the cutover. After this commit:
  - tools.web_tools._exa_search / _exa_extract / _parallel_search /
    _parallel_extract / _tavily_request / _normalize_tavily_* /
    _get_firecrawl_client / _extract_web_search_results /
    _extract_scrape_payload / _to_plain_object / _normalize_result_list
    are no longer called by the dispatchers, but still exist.
  - The config-resolution layer (_get_backend, _is_backend_available,
    _is_tool_gateway_ready, _has_direct_firecrawl_config) IS still in
    use and must stay.
  - The Firecrawl proxy and check_firecrawl_api_key are still imported
    by integration tests and patched by unit tests — must stay (or be
    re-exported from the plugin).
Two regressions discovered by running the full tests/tools/ suite after
the dispatcher cutover, both fixed in this commit:

1. web_crawl_tool incorrectly errored "search-only" for firecrawl
---------------------------------------------------------------------
The cutover treated any provider with supports_crawl()==False as a
search-only backend and returned the typed search-only error. But
firecrawl can crawl via the legacy multi-page-extract path inside
web_crawl_tool — it just doesn't expose supports_crawl on the plugin
(adding native firecrawl crawl is a clean follow-up).

Fix: only emit the search-only error when the provider supports
NEITHER crawl NOR extract (brave-free / ddgs / searxng). When the
provider supports extract but not crawl (firecrawl), fall through to
the legacy firecrawl-via-extract path below.

2. firecrawl plugin's check_website_access wasn't patchable
---------------------------------------------------------------------
The plugin imported `from tools.website_policy import check_website_access`
INSIDE the extract() function body, so monkeypatching the name on
plugins.web.firecrawl.provider had no effect — the inner import re-bound
the name on every call.

Fix: hoist the import to module level. Cheap (website_policy itself
has no heavy deps) and makes the standard
monkeypatch.setattr(firecrawl_provider, "check_website_access", ...)
pattern work.

Test updates (tests/tools/test_website_policy.py — 4 tests):
  - test_web_extract_short_circuits_blocked_url
  - test_web_extract_blocks_redirected_final_url
    Both: patch the gate at plugins.web.firecrawl.provider (where it
    runs after migration) and force the firecrawl plugin to be the
    active extract provider via FIRECRAWL_API_KEY.
  - test_web_crawl_short_circuits_blocked_url
  - test_web_crawl_blocks_redirected_final_url
    Both: unchanged — the dispatcher-level gate at tools.web_tools.py
    line 1651 still uses the imported `check_website_access` name and
    the firecrawl-fallthrough path is exercised as before.

Verified: 22/22 tests/tools/test_website_policy.py pass.
Removes ~580 lines of dead code from tools/web_tools.py that were
superseded by the plugin migration but kept around in the cutover commit
to keep the diff focused. Replaces them with thin re-export shims so
existing tests and external callers that reach for the legacy
``tools.web_tools.<name>`` paths continue to work transparently.

Deleted from tools/web_tools.py
--------------------------------
- Lazy Firecrawl SDK proxy (_load_firecrawl_cls, _FirecrawlProxy,
  _FIRECRAWL_CLS_CACHE, the Firecrawl singleton)
- Firecrawl client section (_get_direct_firecrawl_config,
  _get_firecrawl_gateway_url, _is_tool_gateway_ready,
  _has_direct_firecrawl_config, _raise_web_backend_configuration_error,
  _firecrawl_backend_help_suffix, _get_firecrawl_client)
- Parallel client section (_get_parallel_client,

- Tavily client section (_TAVILY_BASE_URL, _tavily_request,
  _normalize_tavily_search_results, _normalize_tavily_documents)
- Generic SDK normalizers (_to_plain_object, _normalize_result_list,
  _extract_web_search_results, _extract_scrape_payload)
- Exa client section (_get_exa_client, _exa_client, _exa_search,
  _exa_extract)
- Parallel helpers (_parallel_search, _parallel_extract)
- Duplicate inline check_firecrawl_api_key

Net: tools/web_tools.py drops from 2227 → 1613 lines (-614 lines).

Re-exports added at top of tools/web_tools.py
---------------------------------------------
- From plugins.web.firecrawl.provider:
  Firecrawl, _FirecrawlProxy, _FIRECRAWL_CLS_CACHE, _load_firecrawl_cls,
  _get_direct_firecrawl_config, _get_firecrawl_gateway_url,
  _is_tool_gateway_ready, _has_direct_firecrawl_config,
  _firecrawl_backend_help_suffix, _raise_web_backend_configuration_error,
  _get_firecrawl_client, _to_plain_object, _normalize_result_list,
  _extract_web_search_results, _extract_scrape_payload,
  check_firecrawl_api_key
- From plugins.web.tavily.provider:
  _tavily_request, _normalize_tavily_search_results,
  _normalize_tavily_documents
- From plugins.web.parallel.provider:
  _get_parallel_client, _get_async_parallel_client
- From plugins.web.exa.provider:
  _get_exa_client

Plus retained module-level imports for backward-compat with tests:
- httpx (tests patch tools.web_tools.httpx for tavily request mocking)
- build_vendor_gateway_url, _read_nous_access_token,
  resolve_managed_tool_gateway, managed_nous_tools_enabled,
  prefers_gateway (tests patch tools.web_tools.<name>)

Plugin indirection pattern (key technique)
------------------------------------------
For functions inside the firecrawl/parallel/exa plugins to honor
unit-test patches that target ``tools.web_tools.<name>``, the plugin
implementations now do ``import tools.web_tools as _wt`` at call time
and read helper names through that module (``_wt._read_nous_access_token``,
``_wt.Firecrawl``, ``_wt.prefers_gateway``, etc.). This makes the
existing test patches transparently reach the plugin code without any
test changes.

The cached client globals (_firecrawl_client, _firecrawl_client_config,
_parallel_client, _async_parallel_client, _exa_client) also now live on
tools.web_tools so existing test setup_method handlers that reset
``tools.web_tools._<vendor>_client = None`` between cases keep working.
The plugins read/write the cache via getattr/setattr on the web_tools
module.

Verified
--------
- 173/173 targeted web tests pass:
  test_web_providers.py, test_web_providers_brave_free.py,
  test_web_providers_ddgs.py, test_web_providers_searxng.py,
  test_web_tools_config.py, test_web_tools_tavily.py,
  test_website_policy.py, test_config_null_guard.py
- Compile-clean (py_compile.compile passes)
- All inline implementations now exist in exactly one place
  (plugins.web.<vendor>.provider)

Follow-up clean-up
------------------
- Drop _WEB_PLUGIN_SKIPLIST + hardcoded TOOL_CATEGORIES["web"] rows
  (next commit)
- Delete tools/web_providers/ directory entirely
- Add tests/plugins/web/ coverage
- Full tests/tools/ + tests/gateway/ regression sweep before promoting PR
…re sole source

Removes the seven hardcoded TOOL_CATEGORIES["web"] provider rows that
duplicated the plugin-registered providers, and deletes the
_WEB_PLUGIN_SKIPLIST that existed to prevent duplicate picker rows
during the migration. The Web Search & Extract category now derives its
provider rows entirely from agent.web_search_registry via
_plugin_web_search_providers(), matching how Spotify, Google Meet, and
the image_gen plugins are surfaced.

Removed (deduplicated against plugin schemas):
  - Firecrawl Cloud         → plugins.web.firecrawl
  - Exa                     → plugins.web.exa
  - Parallel                → plugins.web.parallel
  - Tavily                  → plugins.web.tavily
  - SearXNG                 → plugins.web.searxng
  - Brave Search (Free Tier) → plugins.web.brave_free
  - DuckDuckGo (ddgs)       → plugins.web.ddgs (post_setup hook preserved)

Retained in TOOL_CATEGORIES["web"]:
  - Nous Subscription   — requires requires_nous_auth +
                          managed_nous_feature + override_env_vars
                          to drive the managed-gateway UX. Not a
                          provider — a different *setup flow* for the
                          firecrawl backend.
  - Firecrawl Self-Hosted — points firecrawl at a private Docker URL
                            via FIRECRAWL_API_URL only. Same reason:
                            UX setup-flow row, not a provider.

These two rows describe alternative auth/billing paths for the
firecrawl backend; they intentionally share web_backend="firecrawl"
with the plugin row but light up different env-var prompts.

Plugin schema extensions
------------------------
- ddgs plugin's get_setup_schema() now emits `post_setup: "ddgs"` so
  selection still triggers the pip-install hook in _run_post_setup().
- _plugin_web_search_providers() passes `post_setup` through verbatim
  when present in the schema (other future plugins like camofox / a
  hypothetical playwright-web plugin can opt in the same way).
- Picker rows now carry both `web_backend` (legacy field consumed by
  setup + selection helpers) and `web_search_plugin_name`
  (informational marker), so behavior is identical between hardcoded
  and plugin-registered rows.

Net diff
--------
- hermes_cli/tools_config.py: -141/+50 lines (~91 lines net)
- plugins/web/ddgs/provider.py: +7/-4 (post_setup field + badge polish)

Verified
--------
- Compile-clean for both files
- Picker shows: 2 hardcoded rows (Nous Subscription, Firecrawl
  Self-Hosted) + 7 plugin rows (alphabetically: Brave Search,
  DuckDuckGo, Exa, Firecrawl, Parallel, SearXNG, Tavily). DuckDuckGo
  row carries post_setup="ddgs" for first-time install.
- 173 web-specific tests still pass.
… ABC tests

Removes the legacy in-tree provider scaffolding that PR NousResearch#25182 fully
replaced with the plugin architecture:

  tools/web_providers/__init__.py        (6 lines)
  tools/web_providers/base.py            (89 lines — old ABCs)
  tools/web_providers/ARCHITECTURE.md    (73 lines — old design doc)

These were the staging-ground ABCs and provider modules that the
plugin migration absorbed. All seven web providers now implement the
single :class:`agent.web_search_provider.WebSearchProvider` ABC and
live under ``plugins/web/<vendor>/``. Nothing else in the tree imports
``tools.web_providers`` — verified via grep before deletion.

Test migration (tests/tools/test_web_providers.py)
--------------------------------------------------
Rewrote ``TestWebProviderABCs`` to test the new unified ABC at
:mod:`agent.web_search_provider`:

  - test_cannot_instantiate_abc_directly — abstract ``name`` + ``is_available``
  - test_concrete_search_only_provider_works — exercise default
    ``supports_extract=False`` / ``supports_crawl=False`` flags
  - test_concrete_multi_capability_provider_works — exercise all three
    capabilities, async extract supported (declared sync here for
    simplicity; real plugins like parallel + firecrawl use async)
  - test_search_only_provider_skips_extract_and_crawl — verify
    ``supports_*()`` flags default to False so search-only providers
    don't have to implement extract() or crawl()

The 9 other tests in the file (per-capability backend selection,
DEFAULT_CONFIG merge, dispatcher routing) test public helpers in
``tools.web_tools`` that still exist and pass unchanged.

agent/web_search_provider.py docstring updated to reflect that the
legacy ABCs no longer exist; the response-shape contract is preserved
bit-for-bit so external consumers see no behavioral change.

Net diff
--------
- tools/web_providers/ removed (-168 lines)
- tests/tools/test_web_providers.py rewritten ABC section (+78/-30 net,
  same coverage, new API)
- agent/web_search_provider.py docstring (-3/+5 lines)

Verified
--------
- 173/173 targeted web tests pass
- 12/12 ABC contract tests pass with the new interface
- No remaining grep hits for ``tools.web_providers`` outside of
  intentional historical references in plugin docstrings.
Adds 44 focused tests under tests/plugins/web/ covering the surface that
the PR NousResearch#25182 web-provider migration introduced. Complements the
existing tests/tools/ coverage which is dispatcher-centric; this file is
plugin-centric and tests each plugin + the registry directly.

Test classes (44 tests, ~1.1s on 4 workers)
-------------------------------------------

TestBundledPluginsRegister (16 tests)
  - All seven plugins present in the registry after
    _ensure_plugins_discovered()
  - Per-plugin parametrized capability-flag assertions
    (brave-free / ddgs / searxng: search-only;
     exa / parallel / firecrawl: search + extract;
     tavily: search + extract + crawl)
  - Every plugin exposes name + display_name properties
  - Every plugin returns a picker-compatible get_setup_schema() dict

TestIsAvailable (7 tests)
  - Each premium plugin reports is_available()==False when its env var is
    absent and True once set (brave-free / searxng / tavily / exa /
    parallel)
  - firecrawl recognizes either FIRECRAWL_API_KEY or FIRECRAWL_API_URL
    as a "configured" signal
  - ddgs is the always-on fallback and must not raise from is_available()

TestRegistryResolution (4 tests)
  - Option B semantics validated end-to-end:
    1. Explicit configured provider wins even when is_available()==False
       (dispatcher surfaces typed credential errors, no silent switch)
    2. Unknown/typo name falls back to first available legacy-preference
       provider
    3. Asking for extract via a search-only backend falls back to an
       extract-capable available provider (capability-incompatible
       branch in _resolve())
    4. No config + no credentials → None (or ddgs if installed)

TestAsyncExtractDispatch (4 tests)
  - parallel + firecrawl extract() are coroutine functions (async path
    in dispatcher uses await)
  - exa + tavily extract() are sync (dispatcher wraps in
    asyncio.to_thread)

TestErrorResponseShapes (7 tests)
  - Plugins return typed error dicts (success=False + "error" key) when
    credentials are missing, never raise
  - async extract() returns list of per-URL error dicts
  - tavily crawl() returns {"results": [{"error": ...}]} on missing
    credentials

Design notes
------------
- All tests use real imports of plugin modules — no mocking of provider
  classes themselves — so they catch drift in the ABC, registry, and
  glue layer simultaneously. Per the hermes-agent-dev skill's E2E
  testing guidance.
- The autouse _isolate_env fixture clears every web-provider env var
  before each test so is_available() reflects the test's setup.
- Resolution tests use the lower-level _resolve() directly rather than
  rebuilding the HERMES_HOME config dance — same observable behavior,
  no sys.modules.pop side-effects that would break the ABC isinstance
  check inside ctx.register_web_search_provider().

…line path

The web-provider migration originally left firecrawl crawl as the only
provider-specific code remaining inline in tools/web_tools.py (~250
lines of Firecrawl-specific crawl orchestration that didn't fit the
plugin's existing surface). This commit closes that gap.

What this adds
--------------
1. plugins/web/firecrawl/provider.py: implement async ``crawl(url, **kwargs)``
   - Accepts the same kwargs as the dispatcher passes to any crawl
     provider (``instructions``, ``depth``, ``limit``); Firecrawl's
     /crawl endpoint ignores ``instructions`` and ``depth`` so we log
     and drop with a clear info message.
   - Wraps the sync SDK ``crawl()`` call in asyncio.to_thread so the
     gateway event loop isn't blocked on a multi-page crawl.
   - Preserves the response-shape normalization across pydantic /
     typed-object / dict variants that the legacy inline code did.
   - Preserves per-page website-policy re-check (catches blocked
     redirects after the SDK returns).
   - Returns the same {"results": [...]} shape so the dispatcher's
     shared LLM-summarization post-processing path works unchanged.
   - Sets supports_crawl() to True so the dispatcher routes through
     the plugin instead of the legacy fallthrough.

2. tools/web_tools.py: delete the entire legacy firecrawl crawl block
   that used to run after "No registered provider supports crawl" —
   ~270 lines including:
   - check_firecrawl_api_key gate + typed error
   - inline SSRF + website-policy seed-URL gate (dispatcher already
     does this)
   - Firecrawl client setup with crawl_params
   - 100+ lines of pydantic/dict/typed-object normalization
   - Per-page LLM-processing loop (kept in the dispatcher's shared
     post-processing path; that's where it always belonged)
   - trimming + base64 image cleanup (still done in the dispatcher's
     shared path)

   Replaced with a single typed-error branch when no crawl-capable
   provider is available: "web_crawl has no available backend. Set
   FIRECRAWL_API_KEY (or FIRECRAWL_API_URL for self-hosted), or set
   TAVILY_API_KEY for Tavily."

Test updates
------------
- tests/tools/test_website_policy.py:
  - test_web_crawl_short_circuits_blocked_url: dispatcher seed-URL
    gate still runs on web_tools.check_website_access (no change to
    that patch), but the firecrawl client lockdown moved to the
    plugin module — patch firecrawl_provider._get_firecrawl_client
    instead of web_tools._get_firecrawl_client. The dispatcher
    short-circuits before the plugin runs, so the test still passes.
  - test_web_crawl_blocks_redirected_final_url: patch the per-page
    policy gate at plugins.web.firecrawl.provider.check_website_access
    (where it now runs) AND on web_tools (where the seed-URL gate
    still runs). Patch firecrawl_provider._get_firecrawl_client for
    the FakeCrawlClient injection. Both checks flow through the same
    fake_check function.
- tests/plugins/web/test_web_search_provider_plugins.py:
  - Update parametrized capability-flag spec: firecrawl supports_crawl
    is now True.
  - Add test_firecrawl_crawl_returns_error_dict_when_unconfigured —
    verifies inspect.iscoroutinefunction(p.crawl) is True and that
    the async crawl returns a per-page error dict (not a raise) when
    FIRECRAWL_API_KEY is missing.

Verified
--------
- 218/218 web tests pass (was 173, +44 plugin tests + 1 new firecrawl
  crawl test from this commit = 218 with the test deduplication).
- Compile-clean (py_compile passes on both files).
- Provider capabilities matrix confirmed end-to-end:
    name        search  extract  crawl   async-extract?  async-crawl?
    firecrawl   True    True     True    True            True
    tavily      True    True     True    False           False
  Both crawl-capable providers exercise the dispatcher's
  inspect.iscoroutinefunction async-or-sync detection.

… cleanup

Self-review of the plugin migration surfaced one warning and a handful of
doc/dead-code cleanups. None affect production behaviour through the main
dispatcher (which always calls `tools.web_tools._get_backend()` first and
preserves the full 7-provider walk), but direct callers of
`agent.web_search_registry.get_active_*_provider()` previously diverged
from the legacy order and could return `None` for users with credentials
but no explicit `web.backend` config key.

Changes
-------
1. `_LEGACY_PREFERENCE` was shipped as a 4-tuple
   `("brave-free", "firecrawl", "searxng", "ddgs")` while the PR
   description and the legacy `_get_backend()` candidate order both
   call for the 7-tuple
   `(firecrawl, parallel, tavily, exa, searxng, brave-free, ddgs)`.
   Replaced with the 7-tuple. Verified empirically: with TAVILY+EXA keys
   and no config, `get_active_search_provider()` now returns tavily
   (was None); with EXA+PARALLEL it returns parallel (was None); with
   BRAVE+FIRECRAWL it returns firecrawl (was brave-free).

2. `agent/web_search_registry.py` — module docstring, `_resolve` step-3
   docstring, and inline comment all listed the old 4-tuple and claimed
   "brave-free first because it was the shipped default". The legacy
   default is `"firecrawl"`. Rewritten to match the new ordering and
   reference `tools.web_tools._get_backend()` as the source of truth.

3. `agent/web_search_registry.py` — `get_active_crawl_provider`
   docstring said "only Tavily implements it among built-in providers".
   Firecrawl also advertises `supports_crawl=True` after the previous
   commit. Updated to "Tavily and Firecrawl".

4. `plugins/web/tavily/provider.py` — module docstring said "Tavily is
   the only built-in backend that natively crawls". Updated.

5. `agent/web_search_provider.py` — ABC docstring mentioned only
   `search` / `extract` capabilities. Added `crawl` for accuracy.

6. `plugins/web/{firecrawl,parallel,exa}/provider.py` — dead plugin-level
   cache globals (`_firecrawl_client`, `_parallel_client`,
   `_async_parallel_client`, `_exa_client`) were declared but never read
   (all reads/writes go through `_wt.*` per the `extracting-inline-
   helpers-to-plugins` recipe). Removed the dead declarations; the
   reset-for-tests helpers in firecrawl + parallel now clear the
   canonical `_wt._<name>` slots, matching the pattern exa already used.

Tests
-----
218/218 web-targeted tests still pass (no test changes needed). 4910/4910
in `tests/tools/` still green.

…registries

Both web_search_registry._resolve() and image_gen_registry.get_active_provider()
walked their registered providers and returned the first one matching the
capability flag — without checking whether that provider was actually
usable. On a fresh install with no credentials at all, this meant
get_active_search_provider() returned `brave-free` (legacy preference
order) even though BRAVE_SEARCH_API_KEY was unset, leading the
dispatcher to surface a "BRAVE_SEARCH_API_KEY is not set" error for a
provider the user never chose. Same bug shape in image_gen for FAL.

Resolution semantics now match tools.web_tools._get_backend():

  1. Explicit config name wins, ignoring is_available() — the dispatcher
     surfaces a precise "X_API_KEY is not set" error rather than silently
     switching backends. Matches user expectation: "I configured X, tell
     me what's wrong with X."
  2. Fallback (no explicit config) walks the legacy preference order
     filtered by is_available() — pick the highest-priority backend the
     user actually has credentials for.

is_available() is wrapped in a try/except so a buggy provider doesn't
brick resolution.

E2E verified:
  - No creds + no config: get_active_search_provider() -> None
  - Explicit brave-free + no key: get_active_search_provider() -> brave-free
    (and .is_available() correctly reports False)

This fix was identified during the spike (NousResearch#25182 finding #1) and is
fold-in to the same PR rather than a follow-up.

… ABC tests

Removes the legacy in-tree provider scaffolding that PR NousResearch#25182 fully
replaced with the plugin architecture:

  tools/web_providers/__init__.py        (6 lines)
  tools/web_providers/base.py            (89 lines — old ABCs)
  tools/web_providers/ARCHITECTURE.md    (73 lines — old design doc)

These were the staging-ground ABCs and provider modules that the
plugin migration absorbed. All seven web providers now implement the
single :class:`agent.web_search_provider.WebSearchProvider` ABC and
live under ``plugins/web/<vendor>/``. Nothing else in the tree imports
``tools.web_providers`` — verified via grep before deletion.

Test migration (tests/tools/test_web_providers.py)
--------------------------------------------------
Rewrote ``TestWebProviderABCs`` to test the new unified ABC at
:mod:`agent.web_search_provider`:

  - test_cannot_instantiate_abc_directly — abstract ``name`` + ``is_available``
  - test_concrete_search_only_provider_works — exercise default
    ``supports_extract=False`` / ``supports_crawl=False`` flags
  - test_concrete_multi_capability_provider_works — exercise all three
    capabilities, async extract supported (declared sync here for
    simplicity; real plugins like parallel + firecrawl use async)
  - test_search_only_provider_skips_extract_and_crawl — verify
    ``supports_*()`` flags default to False so search-only providers
    don't have to implement extract() or crawl()

The 9 other tests in the file (per-capability backend selection,
DEFAULT_CONFIG merge, dispatcher routing) test public helpers in
``tools.web_tools`` that still exist and pass unchanged.

agent/web_search_provider.py docstring updated to reflect that the
legacy ABCs no longer exist; the response-shape contract is preserved
bit-for-bit so external consumers see no behavioral change.

Net diff
--------
- tools/web_providers/ removed (-168 lines)
- tests/tools/test_web_providers.py rewritten ABC section (+78/-30 net,
  same coverage, new API)
- agent/web_search_provider.py docstring (-3/+5 lines)

Verified
--------
- 173/173 targeted web tests pass
- 12/12 ABC contract tests pass with the new interface
- No remaining grep hits for ``tools.web_providers`` outside of
  intentional historical references in plugin docstrings.

Adds 44 focused tests under tests/plugins/web/ covering the surface that
the PR NousResearch#25182 web-provider migration introduced. Complements the
existing tests/tools/ coverage which is dispatcher-centric; this file is
plugin-centric and tests each plugin + the registry directly.

Test classes (44 tests, ~1.1s on 4 workers)
-------------------------------------------

TestBundledPluginsRegister (16 tests)
  - All seven plugins present in the registry after
    _ensure_plugins_discovered()
  - Per-plugin parametrized capability-flag assertions
    (brave-free / ddgs / searxng: search-only;
     exa / parallel / firecrawl: search + extract;
     tavily: search + extract + crawl)
  - Every plugin exposes name + display_name properties
  - Every plugin returns a picker-compatible get_setup_schema() dict

TestIsAvailable (7 tests)
  - Each premium plugin reports is_available()==False when its env var is
    absent and True once set (brave-free / searxng / tavily / exa /
    parallel)
  - firecrawl recognizes either FIRECRAWL_API_KEY or FIRECRAWL_API_URL
    as a "configured" signal
  - ddgs is the always-on fallback and must not raise from is_available()

TestRegistryResolution (4 tests)
  - Option B semantics validated end-to-end:
    1. Explicit configured provider wins even when is_available()==False
       (dispatcher surfaces typed credential errors, no silent switch)
    2. Unknown/typo name falls back to first available legacy-preference
       provider
    3. Asking for extract via a search-only backend falls back to an
       extract-capable available provider (capability-incompatible
       branch in _resolve())
    4. No config + no credentials → None (or ddgs if installed)

TestAsyncExtractDispatch (4 tests)
  - parallel + firecrawl extract() are coroutine functions (async path
    in dispatcher uses await)
  - exa + tavily extract() are sync (dispatcher wraps in
    asyncio.to_thread)

TestErrorResponseShapes (7 tests)
  - Plugins return typed error dicts (success=False + "error" key) when
    credentials are missing, never raise
  - async extract() returns list of per-URL error dicts
  - tavily crawl() returns {"results": [{"error": ...}]} on missing
    credentials

Design notes
------------
- All tests use real imports of plugin modules — no mocking of provider
  classes themselves — so they catch drift in the ABC, registry, and
  glue layer simultaneously. Per the hermes-agent-dev skill's E2E
  testing guidance.
- The autouse _isolate_env fixture clears every web-provider env var
  before each test so is_available() reflects the test's setup.
- Resolution tests use the lower-level _resolve() directly rather than
  rebuilding the HERMES_HOME config dance — same observable behavior,
  no sys.modules.pop side-effects that would break the ABC isinstance
  check inside ctx.register_web_search_provider().

Foundation commit for the browser-provider plugin migration (NousResearch#25214).
Mirrors the architecture established by PR NousResearch#25182 (web providers):

- agent/browser_provider.py — BrowserProvider ABC. Preserves the legacy
  CloudBrowserProvider lifecycle contract bit-for-bit (create_session,
  close_session, emergency_cleanup, session metadata shape) so the
  dispatcher in tools/browser_tool.py becomes a pure registry lookup.
  Renames is_configured() → is_available() for parity with WebSearchProvider.

- agent/browser_registry.py — selection registry with the same
  three-rule resolution as web_search_registry:
    1. Explicit config wins (returns even if is_available() == False so
       the dispatcher surfaces a precise credentials error)
    2. Single-eligible shortcut
    3. Legacy preference walk: browser-use → browserbase, filtered by
       availability. Firecrawl is intentionally NOT in the legacy walk
       (matches pre-migration behaviour — Firecrawl was only reachable
       via explicit browser.cloud_provider: firecrawl).

- hermes_cli/plugins.py — adds ctx.register_browser_provider() facade,
  one-liner mirror of register_web_search_provider().

No plugins registered yet; no dispatcher cutover yet. The next commits
move browserbase/browser-use/firecrawl into plugins/browser/<vendor>/
and switch tools/browser_tool.py over to the registry.

…picker

Drops the three hardcoded browser-provider rows (Browserbase, Browser Use,
Firecrawl) from TOOL_CATEGORIES['browser']['providers'] and replaces them
with runtime injection from agent.browser_registry — mirroring the
_plugin_web_search_providers() pattern PR NousResearch#25182 established for the
Web Search and Extract category.

Adds _plugin_browser_providers() helper in hermes_cli/tools_config.py
that walks list_providers() and builds a TOOL_CATEGORIES-shape dict per
provider via get_setup_schema(). The new visible_providers() hook calls
it for cat['name'] == 'Browser Automation'.

The three remaining hardcoded rows are non-provider UX setup-flow rows:
  - 'Nous Subscription (Browser Use cloud)' — managed Browser Use billed
    via Nous subscription; uses the browser-use plugin as the underlying
    backend but has distinct setup UX (requires_nous_auth gates it).
  - 'Local Browser' — headless Chromium, no CloudBrowserProvider.
  - 'Camofox' — anti-detection local Firefox; _is_camofox_mode()
    short-circuits the cloud-provider dispatch path entirely.

Verified the picker output matches pre-migration order/content:
  Local Browser, Camofox, Browser Use, Browserbase, Firecrawl
(with 'Nous Subscription' surfaced only when the user is Nous-authed,
unchanged from main).

31 tests across 5 classes:

  TestBundledPluginsRegister (8 tests)
    - Three plugins register (browserbase, browser-use, firecrawl)
    - Each plugin's name + display_name accessible
    - get_setup_schema() returns picker-shaped dict with post_setup hook
    - All three lifecycle methods (create_session, close_session,

  TestIsAvailable (4 tests)
    - browserbase needs BOTH BROWSERBASE_API_KEY and BROWSERBASE_PROJECT_ID
    - browserbase: api_key alone or project_id alone insufficient
    - browser-use satisfied by BROWSER_USE_API_KEY
    - firecrawl satisfied by FIRECRAWL_API_KEY

  TestRegistryResolution (8 tests) — most valuable, locks down
                                     pre-migration semantics:
    - _resolve(None) with no creds returns None (local mode)
    - _resolve('local') short-circuits to None
    - _resolve('browserbase') returns provider even when unavailable
      (so dispatcher surfaces typed credentials error)
    - _resolve('firecrawl') same: explicit-config wins
    - _resolve('unknown') falls through to auto-detect
    - Legacy walk picks browser-use over browserbase
    - browserbase-only configuration: browserbase wins
    - **Regression**: firecrawl is NEVER auto-selected even when
      single-eligible (preserves pre-migration gate; FIRECRAWL_API_KEY
      shared with web firecrawl must not silently route to paid cloud
      browser)

  TestLegacyAbcAliases (6 tests)
    - is_configured() delegates to is_available() for all three plugins
    - provider_name() returns display_name for all three plugins

  TestPickerIntegration (3 tests)
    - _plugin_browser_providers() exposes all three plugins as rows
    - Each row carries post_setup='agent_browser'
    - browser_plugin_name marker matches browser_provider

All tests use real imports — no mocking of provider classes — so the
suite catches drift in the ABC, registry, picker injection, and plugin
glue layer simultaneously.

31/31 passing.

Mirrors the architecture established by the web (NousResearch#25182), browser
(NousResearch#25214), and video_gen (NousResearch#25126) plugin migrations:

* `tools/fal_common.py` — stateless atoms shared by both FAL-backed
  plugins (image_gen + video_gen). Holds the lazy `fal_client` import
  helper, `_ManagedFalSyncClient`, `_normalize_fal_queue_url_format`,
  `_extract_http_status`. Stateful pieces (`fal_client` module global,
  `_managed_fal_client*` cache, `_submit_fal_request`,
  `_resolve_managed_fal_gateway`, `_get_managed_fal_client`)
  intentionally stay on `tools.image_generation_tool` so the existing
  `monkeypatch.setattr(image_tool, ...)` patch sites keep working
  unchanged.

* `plugins/video_gen/fal/__init__.py` — drops its inline
  `_load_fal_client` duplicate; consumes `tools.fal_common.import_fal_client`.

* `plugins/image_gen/fal/{plugin.yaml,__init__.py}` — new plugin.
  `FalImageGenProvider` is a thin registration adapter that resolves
  the legacy module via `import tools.image_generation_tool as _it`
  and calls `_it.image_generate_tool` + `_it._resolve_fal_model` at
  call time. The 18-model catalog, `_build_fal_payload`, managed-
  gateway selection, and Clarity Upscaler chaining all remain in
  `tools.image_generation_tool` as the single source of truth —
  the plugin is a registration adapter, not a parallel implementation.

* `tools/image_generation_tool.py::_dispatch_to_plugin_provider` —
  drops the `configured == "fal"` skip. Setting `image_gen.provider:
  fal` now routes through the registry like any other provider; the
  plugin re-enters this module's pipeline so behavior is identical.
  Unset `image_gen.provider` still falls through to the in-tree
  pipeline (preserves no-config-with-FAL_KEY UX from NousResearch#15696).

* `hermes_cli/tools_config.py` — drops the hardcoded "FAL.ai" row from
  `TOOL_CATEGORIES["image_gen"]["providers"]` (now injected by
  `_plugin_image_gen_providers` like every other backend) and the
  `getattr(provider, "name") == "fal"` skip that protected against
  duplication with the hardcoded row. The "Nous Subscription" row
  stays as a setup-flow entry — same shape browser kept "Nous
  Subscription (Browser Use cloud)" after NousResearch#25214.

* `tests/plugins/image_gen/test_fal_provider.py` — 14 cases covering
  the ABC surface, call-time indirection (verifying
  `monkeypatch.setattr(image_tool, "image_generate_tool", ...)` takes
  effect through the plugin), response-shape stamping, exception
  handling, and registry wiring.

* `tests/plugins/image_gen/check_parity_vs_main.py` — subprocess
  harness mirroring `tests/plugins/browser/check_parity_vs_main.py`.
  Pins one path to origin/main, one to the worktree; runs six
  scenarios (unset, explicit-fal-no-creds, explicit-fal-with-creds,
  explicit-fal-with-model, typo provider, managed-gateway-only) and
  diffs the reduced shape `{dispatch_kind, provider_name, model}`
  per scenario. The only acceptable diff is "legacy_fal → plugin
  (fal)" for explicit-FAL paths — every other delta is flagged as
  a regression.

* `tests/hermes_cli/test_image_gen_picker.py::test_fal_surfaced_alongside_other_plugins`
  — flips the previous `test_fal_skipped_to_avoid_duplicate` to
  match the new shape (FAL is a plugin now, no dedup needed).

Verified: 195/195 tests across
`tests/{tools/test_image_generation*,tools/test_managed_media_gateways,plugins/image_gen,plugins/video_gen,hermes_cli/test_image_gen_picker}.py`
pass on this branch with no test patches modified outside the picker
test that asserted the old skip behaviour.

…registries

Both web_search_registry._resolve() and image_gen_registry.get_active_provider()
walked their registered providers and returned the first one matching the
capability flag — without checking whether that provider was actually
usable. On a fresh install with no credentials at all, this meant
get_active_search_provider() returned `brave-free` (legacy preference
order) even though BRAVE_SEARCH_API_KEY was unset, leading the
dispatcher to surface a "BRAVE_SEARCH_API_KEY is not set" error for a
provider the user never chose. Same bug shape in image_gen for FAL.

Resolution semantics now match tools.web_tools._get_backend():

  1. Explicit config name wins, ignoring is_available() — the dispatcher
     surfaces a precise "X_API_KEY is not set" error rather than silently
     switching backends. Matches user expectation: "I configured X, tell
     me what's wrong with X."
  2. Fallback (no explicit config) walks the legacy preference order
     filtered by is_available() — pick the highest-priority backend the
     user actually has credentials for.

is_available() is wrapped in a try/except so a buggy provider doesn't
brick resolution.

E2E verified:
  - No creds + no config: get_active_search_provider() -> None
  - Explicit brave-free + no key: get_active_search_provider() -> brave-free
    (and .is_available() correctly reports False)

  `monkeypatch.setattr(image_tool, ...)` patch sites keep working
  unchanged.

* `plugins/video_gen/fal/__init__.py` — drops its inline
  `_load_fal_client` duplicate; consumes `tools.fal_common.import_fal_client`.

* `plugins/image_gen/fal/{plugin.yaml,__init__.py}` — new plugin.
  `FalImageGenProvider` is a thin registration adapter that resolves
  the legacy module via `import tools.image_generation_tool as _it`
  and calls `_it.image_generate_tool` + `_it._resolve_fal_model` at
  call time. The 18-model catalog, `_build_fal_payload`, managed-
  gateway selection, and Clarity Upscaler chaining all remain in
  `tools.image_generation_tool` as the single source of truth —
  the plugin is a registration adapter, not a parallel implementation.

* `tools/image_generation_tool.py::_dispatch_to_plugin_provider` —
  drops the `configured == "fal"` skip. Setting `image_gen.provider:
  fal` now routes through the registry like any other provider; the
  plugin re-enters this module's pipeline so behavior is identical.
  Unset `image_gen.provider` still falls through to the in-tree
  pipeline (preserves no-config-with-FAL_KEY UX from #15696).

* `hermes_cli/tools_config.py` — drops the hardcoded "FAL.ai" row from
  `TOOL_CATEGORIES["image_gen"]["providers"]` (now injected by
  `_plugin_image_gen_providers` like every other backend) and the
  `getattr(provider, "name") == "fal"` skip that protected against
  duplication with the hardcoded row. The "Nous Subscription" row
  stays as a setup-flow entry — same shape browser kept "Nous
  Subscription (Browser Use cloud)" after #25214.

* `tests/plugins/image_gen/test_fal_provider.py` — 14 cases covering
  the ABC surface, call-time indirection (verifying
  `monkeypatch.setattr(image_tool, "image_generate_tool", ...)` takes
  effect through the plugin), response-shape stamping, exception
  handling, and registry wiring.

* `tests/plugins/image_gen/check_parity_vs_main.py` — subprocess
  harness mirroring `tests/plugins/browser/check_parity_vs_main.py`.
  Pins one path to origin/main, one to the worktree; runs six
  scenarios (unset, explicit-fal-no-creds, explicit-fal-with-creds,
  explicit-fal-with-model, typo provider, managed-gateway-only) and
  diffs the reduced shape `{dispatch_kind, provider_name, model}`
  per scenario. The only acceptable diff is "legacy_fal → plugin
  (fal)" for explicit-FAL paths — every other delta is flagged as
  a regression.

* `tests/hermes_cli/test_image_gen_picker.py::test_fal_surfaced_alongside_other_plugins`
  — flips the previous `test_fal_skipped_to_avoid_duplicate` to
  match the new shape (FAL is a plugin now, no dedup needed).

Verified: 195/195 tests across
`tests/{tools/test_image_generation*,tools/test_managed_media_gateways,plugins/image_gen,plugins/video_gen,hermes_cli/test_image_gen_picker}.py`
pass on this branch with no test patches modified outside the picker
test that asserted the old skip behaviour.

…registries

Both web_search_registry._resolve() and image_gen_registry.get_active_provider()
walked their registered providers and returned the first one matching the
capability flag — without checking whether that provider was actually
usable. On a fresh install with no credentials at all, this meant
get_active_search_provider() returned `brave-free` (legacy preference
order) even though BRAVE_SEARCH_API_KEY was unset, leading the
dispatcher to surface a "BRAVE_SEARCH_API_KEY is not set" error for a
provider the user never chose. Same bug shape in image_gen for FAL.

Resolution semantics now match tools.web_tools._get_backend():

  1. Explicit config name wins, ignoring is_available() — the dispatcher
     surfaces a precise "X_API_KEY is not set" error rather than silently
     switching backends. Matches user expectation: "I configured X, tell
     me what's wrong with X."
  2. Fallback (no explicit config) walks the legacy preference order
     filtered by is_available() — pick the highest-priority backend the
     user actually has credentials for.

is_available() is wrapped in a try/except so a buggy provider doesn't
brick resolution.

E2E verified:
  - No creds + no config: get_active_search_provider() -> None
  - Explicit brave-free + no key: get_active_search_provider() -> brave-free
    (and .is_available() correctly reports False)

This fix was identified during the spike (NousResearch#25182 finding NousResearch#1) and is
fold-in to the same PR rather than a follow-up.

… ABC tests

Removes the legacy in-tree provider scaffolding that PR NousResearch#25182 fully
replaced with the plugin architecture:

  tools/web_providers/__init__.py        (6 lines)
  tools/web_providers/base.py            (89 lines — old ABCs)
  tools/web_providers/ARCHITECTURE.md    (73 lines — old design doc)

These were the staging-ground ABCs and provider modules that the
plugin migration absorbed. All seven web providers now implement the
single :class:`agent.web_search_provider.WebSearchProvider` ABC and
live under ``plugins/web/<vendor>/``. Nothing else in the tree imports
``tools.web_providers`` — verified via grep before deletion.

Test migration (tests/tools/test_web_providers.py)
--------------------------------------------------
Rewrote ``TestWebProviderABCs`` to test the new unified ABC at
:mod:`agent.web_search_provider`:

  - test_cannot_instantiate_abc_directly — abstract ``name`` + ``is_available``
  - test_concrete_search_only_provider_works — exercise default
    ``supports_extract=False`` / ``supports_crawl=False`` flags
  - test_concrete_multi_capability_provider_works — exercise all three
    capabilities, async extract supported (declared sync here for
    simplicity; real plugins like parallel + firecrawl use async)
  - test_search_only_provider_skips_extract_and_crawl — verify
    ``supports_*()`` flags default to False so search-only providers
    don't have to implement extract() or crawl()

The 9 other tests in the file (per-capability backend selection,
DEFAULT_CONFIG merge, dispatcher routing) test public helpers in
``tools.web_tools`` that still exist and pass unchanged.

agent/web_search_provider.py docstring updated to reflect that the
legacy ABCs no longer exist; the response-shape contract is preserved
bit-for-bit so external consumers see no behavioral change.

Net diff
--------
- tools/web_providers/ removed (-168 lines)
- tests/tools/test_web_providers.py rewritten ABC section (+78/-30 net,
  same coverage, new API)
- agent/web_search_provider.py docstring (-3/+5 lines)

Verified
--------
- 173/173 targeted web tests pass
- 12/12 ABC contract tests pass with the new interface
- No remaining grep hits for ``tools.web_providers`` outside of
  intentional historical references in plugin docstrings.

Adds 44 focused tests under tests/plugins/web/ covering the surface that
the PR NousResearch#25182 web-provider migration introduced. Complements the
existing tests/tools/ coverage which is dispatcher-centric; this file is
plugin-centric and tests each plugin + the registry directly.

Test classes (44 tests, ~1.1s on 4 workers)
-------------------------------------------

TestBundledPluginsRegister (16 tests)
  - All seven plugins present in the registry after
    _ensure_plugins_discovered()
  - Per-plugin parametrized capability-flag assertions
    (brave-free / ddgs / searxng: search-only;
     exa / parallel / firecrawl: search + extract;
     tavily: search + extract + crawl)
  - Every plugin exposes name + display_name properties
  - Every plugin returns a picker-compatible get_setup_schema() dict

TestIsAvailable (7 tests)
  - Each premium plugin reports is_available()==False when its env var is
    absent and True once set (brave-free / searxng / tavily / exa /
    parallel)
  - firecrawl recognizes either FIRECRAWL_API_KEY or FIRECRAWL_API_URL
    as a "configured" signal
  - ddgs is the always-on fallback and must not raise from is_available()

TestRegistryResolution (4 tests)
  - Option B semantics validated end-to-end:
    1. Explicit configured provider wins even when is_available()==False
       (dispatcher surfaces typed credential errors, no silent switch)
    2. Unknown/typo name falls back to first available legacy-preference
       provider
    3. Asking for extract via a search-only backend falls back to an
       extract-capable available provider (capability-incompatible
       branch in _resolve())
    4. No config + no credentials → None (or ddgs if installed)

TestAsyncExtractDispatch (4 tests)
  - parallel + firecrawl extract() are coroutine functions (async path
    in dispatcher uses await)
  - exa + tavily extract() are sync (dispatcher wraps in
    asyncio.to_thread)

TestErrorResponseShapes (7 tests)
  - Plugins return typed error dicts (success=False + "error" key) when
    credentials are missing, never raise
  - async extract() returns list of per-URL error dicts
  - tavily crawl() returns {"results": [{"error": ...}]} on missing
    credentials

Design notes
------------
- All tests use real imports of plugin modules — no mocking of provider
  classes themselves — so they catch drift in the ABC, registry, and
  glue layer simultaneously. Per the hermes-agent-dev skill's E2E
  testing guidance.
- The autouse _isolate_env fixture clears every web-provider env var
  before each test so is_available() reflects the test's setup.
- Resolution tests use the lower-level _resolve() directly rather than
  rebuilding the HERMES_HOME config dance — same observable behavior,
  no sys.modules.pop side-effects that would break the ABC isinstance
  check inside ctx.register_web_search_provider().
