fix(acp): expose Droid and Kimi skills in picker by noelsaw1 · Pull Request #27963 · pingdotgg/t3code

noelsaw1 · 2026-10-31T03:03:23Z

Droid advertises skills as unprefixed ACP commands, while Kimi uses skill: names. The registry adapter classified only $-prefixed commands as skills, leaving the $ picker empty for Droid and misclassifying Kimi skills as slash commands.

This adds provider-specific command normalization and rewrites selected, catalog-validated skill mentions to each agent’s native invocation form. Other ACP providers and unknown $mentions are unchanged. ACP provider documentation is updated accordingly.

Closes https://git.cafe/pingdotgg/t3code/issues/27108.

Validation: vp run check:changed passed; 47 affected tests passed, including new Droid/Kimi discovery and invocation regressions that failed before the fix. No live Droid turn was run.

Model: Kimi k3.1-pro. Harness: Kimi Code in T3 Code.

Fixes #27108

Approvability

Verdict: Approved at 9d9a76b

Macroscope's review found this PR approvable — Droid and Kimi skills become available in the picker, with leading skill mentions translated into each agent's native command syntax. The change is limited to advertised, enabled skills for those providers and leaves other providers unchanged.

Walkthrough

The ACP Registry now stores available-command catalogs by session and classifies Droid’s unprefixed commands and Kimi’s skill: commands as skills. For Droid and Kimi, the adapter can rewrite leading mentions of enabled skills to native command forms.

Changes: ACP Registry skill handling

Layer / File(s)	Summary
Session-scoped command catalogs `packages/provider-acp/src/server/adapter.ts`, `packages/provider-acp-registry/src/server/AcpRegistryRuntimeCoordinator.ts`, `packages/provider-acp-registry/src/server/AcpRegistryRuntimeCoordinator.test.ts`	The ACP adapter passes session IDs with available-command updates and text rewrites. The runtime coordinator stores catalogs by instance and session, retrieves the requested session’s catalog, and clears session catalogs with their instance. Tests cover separate catalogs for two sessions.
Provider-specific skill classification `packages/provider-acp-registry/src/server/probe.ts`, `apps/server/src/provider/AcpRegistryProbe.test.ts`, `docs/user/providers-acp.md`	Normalization recognizes unprefixed Droid command names and Kimi `skill:` names as skills. Tests cover these rules, and the documentation describes the command forms.
Enabled skill mention rewriting `packages/provider-acp-registry/src/server/probe.ts`, `packages/provider-acp-registry/src/server/adapter.ts`, `packages/provider-acp-registry/src/testing.ts`, `apps/server/src/provider/AcpRegistryProbe.test.ts`	For Droid and Kimi, the adapter uses available commands for the active session to rewrite leading mentions of enabled skills to native command forms. Tests cover matching skills, missing skills, and other agent IDs.

Merge Risk: Low · up to 2d95d

Droid skills now appear in the $ picker and are invoked in Droid's native form. Users who turn off skills in the slash menu will no longer see Droid's commands under "/". This is a small, bounded regression worth fixing but not a merge blocker.

Full details: Linked Issues check

Explanation

Issue #27108 requires Droid's unprefixed ACP commands to appear as skills in the $ picker. normalizeAcpRegistryCommands classifies unprefixed commands as skills for factory-droid. The adapter passes the registry agent ID and stores catalogs per session. rewriteAcpRegistrySkillMention rewrites enabled, catalog-validated leading mentions to Droid's native /name form. Tests cover Droid discovery, native invocation, unknown mentions, and other agents.

Full details: Out of Scope Changes check

Explanation

The changes stay within ACP command discovery and invocation. Kimi normalization uses the same provider-specific classification and native invocation path described in the current PR intent. Session-scoped catalog storage, adapter integration, exports, tests, and documentation support these changes. No unrelated change is demonstrated.

mention-rewriting callback from provider-instance state to state scoped to the
active ACP session or thread. Use the session or thread context available to
rewriteUserText for lookups, and ensure command updates are associated with that
same identifier so one session’s skills cannot affect another session’s turn.

Takeover update

merged current main into the branch with a merge commit (2d95db8b7f). two conflicts, both import lists in packages/provider-acp-registry/src/testing.ts and apps/server/src/provider/AcpRegistryProbe.test.ts; kept main's probeAcpRegistryConfiguration and this PR's rewriteAcpRegistrySkillMention.
no code changes beyond the merge. the PR diff against main is the same 8 files.
vp run check:changed against main passes: format, lint, knip, typecheck (14 packages), 26 tests in the 3 affected files.
the one review finding (session-scoped command catalogs) was already addressed in ce65b0a551 and resolved.

Verified in a real dev environment

verified the kimi path at exact head ce65b0a55129c605c845eff289a37a14ed440a41, after reproducing the bug on github/main at 54c5f252. used repository playwright with /usr/bin/google-chrome, one background dev server at a time, and isolated state. created the git project and skill through the app with real codex gpt-6.1-sol turns.

on main, $ reported no skills while /skill:repo-summary appeared as a slash command. on this head, the same real skill appeared as Repo Summary in the skill picker. selecting and submitting it completed a real kimi turn that read the readme and git status. the native kimi event recorded kind=skill_activation, skillName=repo-summary, trigger=user-slash, proving native command activation.

used registry source kimi with its supported executable override pointing to official kimi code 2.4.1, and gpt-6.1-sol through this vm's existing local responses api proxy.

nearby checks passed: an unknown $unadvertised-pr27963 reached kimi unchanged and was echoed literally; /compact remained in the commands picker; a fresh codex gpt-6.1-sol turn on this head read the repository and returned the correct git status. the 22 existing focused probe/coordinator tests passed through blacksmith-check. ci reports 21 passed and 7 skipped checks, with no failures or pending checks. no source changes or pushes were needed.

main, same project and skill:

pr, same project and skill:

selection, submission and completed provider response; idle waiting in the middle is cut:

short command transcript and native event excerpts

Not verified

droid skill discovery and invocation: installed factory droid 1.1.0 from the registry through the app, but its session probe timed out after 60 seconds and no model could be selected. its native log reports no authentication credentials available.
registry-pinned python kimi 1.52.0 with kimi oauth: that build required an account token even with custom model configuration, so the successful run used the supported 2.4.1 executable override described above.
native desktop/mobile clients, macos/windows, relay/tunnel connections, and separate-session skill catalogs with different skill sets were not exercised. /compact was inspected in the picker but not executed.
