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 #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 pingdotgg/t3code#27108
Added 1 commit
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.
You can add or adjust custom eligibility rules. Learn more.
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.

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.
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.

Use session-scoped command state for mention rewriting.
AcpRegistryRuntimeCoordinator stores one command list per provider instance, and each command update replaces that list. The same provider instance can open multiple ACP sessions, but updates do not include a session identifier. If another session publishes its project-scoped skills last, rewriteUserText can validate the current turn against that session’s skills and rewrite $name to a command unavailable in the current session.
rewriteUserText receives thread and provider-session context, but the registry callback ignores it. Store commands by the active ACP session or thread, propagate that identifier with each command update, and use the current turn’s identifier for the lookup. The coordinator currently exposes no per-session command list.

✅ Confirmed as addressed by @noelsaw1
Addressed in ce65b0a55129c605c845eff289a37a14ed440a41. Command catalogs are now keyed by provider instance and native ACP session ID. Advertisement and prompt rewriting propagate the same session ID, while the instance-wide provider snapshot remains unchanged and a session without a catalog fails closed. The new regression covers two sessions with different catalogs plus clearing. Serialized check:changed and all 48 affected tests pass; independent Claude Code Opus 5.5 QA also approved the final head.
@noelsaw1 Thanks for addressing this in ce65b0a55129c605c845eff289a37a14ed440a41. The supplied adapter code now passes the native ACP session ID to both command publication and mention-rewriting lookup. This matches the requested session isolation.
Your reported regression coverage checks separate catalogs and clearing. I have not independently rerun the checks or tests.
I couldn't check this conversation for new learnings, so no new learning was saved.

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.
