Problem

With OpenCode 2.2.5, a freshly spawned managed opencode serve can take about a minute to activate its location plugins. During that window /api/model holds each request for 5 s, then answers 503 ServiceUnavailableError (service: "plugin"). T3's model probe gave up after 5 s, so the OpenCode card showed "OpenCode 2 is running, but it did not list any models yet." and every OpenCode model in the picker showed Unavailable. The probe then released the serve, which idle-stops after 30 s, before activation finished. Every later probe (manual refresh or the 5-minute interval re-check) started a new cold serve and lost the same race, so the card never recovered.

Reproduced on main (cefb544) in the web app with a fresh database and real @opencode/cli 2.2.5 behind a wrapper that answers model reads the way 2.2.5 does during a 60 s activation (transcript below). Adding an OpenCode instance, "Refresh provider status" and the 5-minute re-check each spawned a cold serve, made one model read, and left the card on that warning.

Change

makeOpenCode2ModelLoader now reads in two steps. The first read retries, 1 s apart, while OpenCode answers with the plugin-activation ServiceUnavailableError (matched on the typed error inside OpenCodeRuntimeError.cause, not on message text), under a 2-minute deadline. Each retry borrows the managed serve again, which cancels its pending idle stop, so the same serve stays up until activation finishes. Once a read succeeds, the existing agreeing-reads loop runs with its 5 s budget, and the warm-cache fallback is unchanged. Any other error still fails straight away.

Scope and approval

Fixes #30251

Verification

  • keeps reading OpenCode 2 models until its location plugins finish activating (packages/provider-opencode/src/server/status.test.ts, TestClock) models 2.2.5: each read is held 5 s, then 503s with the wrapped plugin error until 60 s. It fails on main with [], the result behind the card warning, and passes with the fix. status.test.ts, openCode2Catalog.test.ts and driver.test.ts pass. vp run check:changed passes: format, lint, knip, typecheck of 10 packages, tests.

  • Runtime transcript from the real web app with opencode 2.2.5 behind the fault wrapper (log lines are the wrapper's view of T3's requests):

    Main: one read per serve. The serve stops about 35 s later, and each probe starts a new cold one. The card reads "Needs attention · OpenCode 2 is running, but it did not list any models yet."

    16:32:43.741Z pid=1842320 +0.0s spawned real serve, activation 60s      (instance added)
    16:32:44.128Z pid=1842320 +0.4s GET /api/model -> 503 (activating)

    16:35:27.657Z pid=1854845 +0.5s GET /api/model -> 503 (activating)
    

    Fix: one serve. T3 reads every ~6 s (5 s server hold plus 1 s retry) until activation ends. The card reads "Authenticated · OpenCode 2.2.5 lists 116 models."

    16:44:44.126Z pid=1904762 +0.0s spawned real serve, activation 60s

    16:45:45.992Z pid=1904762 +61.9s GET /api/model -> forwarded
    
  • Not checked: a natively slow 2.2.5 cold start. On the test VM a cold 2.2.5 serve lists its models in about 3 s, so the activation window was injected at the HTTP boundary. The wrapper's 503 is the one in the 2.2.5 binary: model reads wait 5 s for activation, then fail with ServiceUnavailableError("Location plugins did not finish activating", service "plugin"). No screenshots are attached: the evidence upload tool was unavailable on the triage machine, and the card text is quoted above instead.

…activation

This test reproduces #30251. While OpenCode 2.2.5's location plugins are
still activating, it holds each model read for 5 seconds and then answers
503 ServiceUnavailableError. The OpenCode 2 model loader times out after
5 seconds and returns no models. It should keep reading until activation
finishes.

Co-Authored-By: Claude Opus 5.5 <[email protected]>
A cold OpenCode 2.2.5 server answers model reads with a 503
ServiceUnavailableError (service "plugin") until its location plugins
finish activating, which can take about a minute. The model loader capped
everything at 5 seconds and stopped on the first failure, so it released
the managed server, which idled out before activation finished, and every
later probe lost the same race.

The loader now retries the first read while OpenCode reports plugin
activation, under a 2 minute deadline, and runs the agreeing-reads loop
with its 5 second budget once the server answers. Other failures and the
warm-cache fallback behave as before.

Fixes #30251

Approvability

Verdict: Approved at 4a17135

Macroscope's review found this PR approvable — OpenCode 2 model discovery now waits through plugin activation with bounded retries rather than prematurely returning an empty catalog. The change is limited to discovery timing, with existing settling and cached-catalog safeguards retained.

Merge Risk: Minimal · up to 4a171

The change makes OpenCode 2 model discovery wait for plugin activation instead of publishing an empty model list. No actionable merge-blocking risk is evident from the supplied context. The author reports that a natively slow start now reaches ready with models. The PR also conflicts with main in status.ts, which needs resolving before merge.

Full details: Title check

Explanation

The title "fix(opencode): models load once OpenCode 2 finishes activating its plugins" names the main change. The changeset adds a retry loop for plugin-activation ServiceUnavailableError under a two-minute deadline in makeOpenCode2ModelLoader, and removes the five-second timeout on client.model.list in readCatalog. The title is specific, follows conventional commit format, and matches the linked issue's cold-start problem. The title is 74 characters, which is within a normal length range.

Full details: Description check

Explanation

The description follows the repository template closely. It has Problem, Change, Scope, and Verification sections, and each contains specific content. The Problem section gives the expected and observed behavior and the reproduction environment. The Change section explains the two-step read, the retry rule, and the typed-error matching. The Scope section links issue #30251. The Verification section names the focused test, lists the commands that passed, gives a runtime transcript, and states what was not checked. The description also explains why no screenshots are attached. The Scope section does not explain why the change is a bug fix rather than a feature, but the Problem section makes that clear. The description also says the change borrows the serve again, which differs from the issue's same-borrower requirement, but that is an implementation choice and not a template gap.

Full details: Out of Scope Changes check

Explanation

The whole-PR diff changes status.ts and openCode2Catalog.ts, plus their tests. In status.ts, the changes add the ServiceUnavailableError import, the isActivatingPlugins predicate, the 2-minute plugin-activation deadline, the retry on the first read, and the None branch that skips settling. In openCode2Catalog.ts, the change removes the 5 s MODEL_LIST_TIMEOUT from client.model.list, which the commit message describes as bounding the initial read by the loader deadline. Each change supports #30251 cold-start model discovery. The openCode2Catalog.test.ts changes add effectful stub responses and regression tests for 503 during activation and for a never-responding endpoint. These support the linked behavior. No unrelated source change appears in the reviewed diff summary.

Full details: Linked Issues check

Explanation

Directly linked issue [#30251] asks for bounded retries on activation-related unavailable results and not-yet-populated catalogs, over about 90 seconds, with capped backoff. The head diff against merge base f313d0a covers the activation case. In status.ts, the first tracked read uses Effect.retry with isActivatingPlugins (typed ServiceUnavailableError with service === "plugin" inside OpenCodeRuntimeError.cause) and Schedule.spaced("1 second"), bounded by Effect.timeoutOption("2 minutes"). Each retry borrows the managed serve again. Retries at 1 s stay inside the 30 s idle TTL, so the serve stays up. openCode2Catalog.ts removes the 5 s MODEL_LIST_TIMEOUT, so the initial read is bounded by the loader deadline. The not-yet-populated case is not covered. A successful first read that returns an empty catalog is not retried. It goes to settleOpenCode2Catalog, which runs under the 5 s settle budget. The comment in openCode2Catalog.ts says model reads already retry empty catalogs, but the diff adds no such retry and no retry exists in readCatalog, so that comment is not supported by the code. Deadline expiry now yields Option.none and skips settling. Downstream handling of that None is not in the diff, so it is unconfirmed that it produces a loading or failed state rather than a completed empty warning. Requirement differences: the PR uses a 2-minute deadline, which is within the issue's approximately 90 s window only in the sense of a wider bound; the PR re-borrows the serve on each retry rather than holding one borrower, which the issue names explicitly. The 1 s retry interval keeps the serve alive, so this difference is a design choice, but it is not the issue's stated approach.

Resolution

Retry successful reads that return an empty or not-yet-populated catalog within the same bounded activation window. Keep the borrowed serve for those retries. Add a test in openCode2Catalog.test.ts that models a successful empty read during activation followed by a populated catalog, and assert two models are returned. Show in code how the Option.none result from the deadline reaches the driver, and confirm it yields a loading or failed state and does not produce a completed warning with an empty model list. Correct or remove the comment that says model reads already retry empty catalogs.

The automated pipeline stopped on this pull request and will not merge it:

the capture step could not show the problem on the base commit, so there is nothing to prove fixed.

On each commit, open Settings > Providers, add an OpenCode instance using the isolated 2.2.5 binary, and leave the external server URL blank. Initial discovery returned 121 models on both sides. After more than the managed server's 30-second idle timeout, record clicking Refresh provider status. Both refreshes completed with 121 models. The recordings start with cached authenticated inventory and do not demonstrate models appearing from an empty state.

It stays open for a person to finish or close.

Tested with a natively slow OpenCode 2.2.7

The pipeline stopped because the VM's cold serve was too fast to show the bug on base. I got a real slow start without faking HTTP responses: the OpenCode instance's binaryPath was a wrapper that runs the real opencode serve (2.2.7) under a 10% CPU quota (systemd-run --user --scope -p CPUQuota=10%). Throttled like that, the server's first /api/model answer is 503 {"code":"service_starting"}. For about 20 seconds after that it holds each read and then returns the real ServiceUnavailableError with service: "plugin", and then it lists its models.

Setup: Linux x64, node apps/server/src/bin.ts --base-dir <fresh dir> with no cached provider status, so the models have to appear from an empty state. Each row is a separate fresh boot. I read caches/opencode.json after the first OpenCode probe:

Commit Result
d290c1f (this PR's base) warning, 0 models, "OpenCode 2 is running, but it did not list any models yet." (2 of 2)
470cccf (this PR) ready, "OpenCode 2.2.7 lists 121 models." (2 of 2, 42 s and 50 s after start)
470cccf, no CPU quota ready, 121 models, about 10 s after start (normal boots on main took 8 to 9 s)
main at 6807c3f, which has #35049 warning, 0 models (3 of 3)

So #35049 alone does not cover this case. Its 5 second model-read timeout runs out while the server is still activating, and nothing retries the plugin 503. This PR now conflicts with main in status.ts because of #35049.

For context, on a Raspberry Pi 5 running 0.1.9 with managed OpenCode 2.2.7, the server logged OpenCode discovery failed with phase: models, outcome: empty six times yesterday, two of them right after a restart. A cold serve on the idle Pi lists its models in about 2.4 s, so the slow starts there come from the host being busy, which the CPU quota stands in for.

…st timeout

OpenCode holds a model read 5 seconds for plugin activation before it
answers 503, so the 5 second client timeout turned every held read into
an empty catalog and the activation retry never saw the error. Raise the
model list timeout to 8 seconds, and test the retry through the real
catalog reader over HTTP instead of a stub list.

…on answers

On a busy host a cold OpenCode 2.2.7 took about 14 seconds to answer a
model read with its plugin-activation 503, and about 9 seconds for the
first successful read. Any fixed per-request timeout in the catalog
reader turned those reads into an empty list, so the activation retry
never ran. Drop the reader's timeout: the loader's activation deadline
bounds the first read and its settle budget bounds the rest, and the
per-project read keeps its own settle budget.

the driver, and confirm it yields a loading or failed state and does not produce

says model reads already retry empty catalogs.

Evidence

Linux web client, Chrome 151, 1440×1000, light theme. Each revision used fresh isolated T3 and OpenCode state with no cached OpenCode inventory. Add OpenCode in Settings > Providers using real OpenCode 2.2.7 under a 10% CPU quota for serve; leave Server URL blank; run initial discovery once; inspect Settings and the composer model picker. Environment names and executable paths are visually masked.

Portable reproduction wrapper · Browser command transcript · Privacy CSS script · Sanitized runtime summary

Base completed with warning and 0 models. Head waited through real model-endpoint 503 responses and completed with 20 models, without another manual refresh. The unconfigured catalog differs from the PR comment's authenticated 121-model catalog.

Not shown:

  • OpenCode 2.2.5 and cold starts exceeding the bounded discovery deadline were not exercised; this proof covers successful activation with OpenCode 2.2.7.
