## Overview

**Category:** improvement
**User Impact:** Users can see which agents run remotely and understand
where their work and files live.

**Problem:** Remote and local agents looked alike in creation and
conversation, leaving people to infer what an agent could access and
whether it needed their desktop online.

**Solution:** Group harness choices by location, explain remote work
before creation, and add confirmed remote cues to settings, mentions,
messages and activity. Builderlab sign-in is explicit, and availability
and file-access promises stay specific to Builderlab.


This desktop change excludes the separate Model-row width fix in #2577.
The only shared design-system change is the Tabler cloud export.

## Changes

<details>
<summary>File changes</summary>

**docs/agents.md**
Document configuration-owned creation readiness and the presentational
provider action beside Harness.

Cover remote-location fallback and precedence of received activity
details.

Export the Tabler cloud used by the remote cues.

**tests/browser/agent-creation-review.spec.mjs**
Verify animated glyph containment for a valid long name at narrow/wide
widths and enlarged text in both themes, while ordinary words remain
grouped.

## Reproduction steps

1. Open Create agent and inspect Harness. Choices appear under Remote
and Local. Select Builderlab while signed out: Sign in sits beside
Harness, and Model, Thinking and Create agent remain disabled.
2. Begin sign-in. A spinner appears first; browser guidance and Cancel
sign-in appear after three seconds. Cancel and verify the draft remains.
Complete sign-in and choose a model and thinking level.
3. Give the remote agent a name and avatar, then choose Create agent.
Verify the introduction uses that identity. Back returns to the retained
draft; Let’s go creates the agent. With reduced motion enabled, the copy
appears immediately. At 480px width and 20px root text, try the valid
name `production-infrastructure-validation-automation-agent`: its
animated text wraps inside the speech bubble.
4. Open the signed-in Builderlab agent’s Identity settings. The cloud
accompanies Remote agent and the smaller Runs on a Builderlab machine
subtitle. In Settings, Workspace explains that the runtime is shared
with your other agents in this workspace by default, followed by
availability and file-access guidance. When the shared session is signed
out, Workspace hides and the profile pill says Signed out of Builderlab.
Organization sign-out is managed in Identity.
5. Mention a known remote agent without model or session controls: no
workspace button appears beside Send. When model, effort or session
controls are available, open the existing gauge. Select a model, change
effort and compact the session, then dismiss the popover. Verify the
draft and recipients remain and focus returns to the gauge. Check local
targets retain the same controls.
6. Start a remote turn. Remote appears beside the owner’s agent name; a
cloud precedes received activity, pulses while active and stays still
afterward. Enable reduced motion and verify the cloud stays still.
Unknown execution locations receive no remote cue.
7. If a non-Builderlab remote runtime is available, verify its generic
wording makes no Builderlab availability or file-access promises.

## Validation

- Integrated main `fd6296a5c067189e713e28a900dd0547919452c8` into the
feature with merge commit `e21dba8a1530fdcf676209b9fc100b714a721c24`,
preserving published history. The shared native Builderlab session,
agent-card draft adoption, remote introduction and configuration-owned
readiness coexist. The current mainline composer implementation is
retained, including the gauge and existing controls; the withdrawn cloud
stays absent.
- The resolution candidate committed as `e21dba8a1` passes all 114 tests
in the six complete affected unit files (13.95 seconds). Coverage
includes native sign-in failure/cancellation/retry, the held catalog,
creation recovery and imported card drafts surviving the introduction
and Back.
- All six existing creation browser cases pass in Chromium and WebKit
(12.7 seconds) at `c83f62b7d`. The subsequent amendment changes test
fixtures only; production code is identical. The browser cases cover
narrow/wide enlarged-text containment, owner review and failed creation
recovery. No browser cases were added or removed in this integration.
- All mandatory push gates passed on
`e21dba8a1530fdcf676209b9fc100b714a721c24`: TypeScript/related units
(797.24 seconds), design checks (5.98 seconds), Rust selection and
publication-policy guards. The remote SHA is verified. A stale local
Vitest glob transform was cleared; the unchanged README registry test
and normal gate then passed. Hosted checks are pending at publication.
- Earlier composer preservation checks at `0d33b00a1` passed 535 unit
tests and all 14 composer browser cases. The long-name containment
regression and unchanged five-second timeout diagnostics remain in the
feature.
- Ready status is retained. Browser checks use production components in
fixtures. Native IPC, a live account/browser switch and human acceptance
were not rerun. Existing recordings and captures predate the
native-session integration; no new native capture is claimed.

## Screenshots / demos

**Real desktop recording (before the native-session integration).**
Creating a Builderlab agent: Sign in beside Harness, choosing a model
and thinking level, the "Meet your remote agent" introduction, then the
new agent's Remote agent card in its details.

Real native captures from the running desktop build. The signed-in
settings note and signed-out creation controls were exercised. Active
execution animation is not shown. The obsolete composer disclosure
capture has been removed after withdrawing that cue.
