fix(kiro): Kiro skills show in the / and $ menus - #31700
On Kiro threads the composer never offers Kiro skills. Kiro (kiro-cli 2.37.1 and 3.0.0) reports a session's skills only in ACP available_commands_update, as commands with _meta.kiro.type: "skill", and the Kiro provider ignored that update, so the provider snapshot kept skills: []. Reproduced on main with the real kiro-cli 2.37.1 and ~/.kiro/skills/probe-skill/SKILL.md: after a Kiro session started, /probe showed "No matching command." and $probe showed "No skills found. Try / to browse provider commands." Kiro also runs a command only when the message starts with /name, while the $ picker inserts $name.
Change
The Kiro adapter sets onAvailableCommandsUpdate and records the advertised skills in a store owned by the Kiro instance (packages/provider-kiro/src/server/skills.ts). Skills are merged by name across the instance's sessions, so Kiro's first update of a session (which has no skills yet) and other sessions do not clear them. Skills Kiro scopes to a workspace (source.origin: "workspace" with a root) are left out, because the provider snapshot is shared by every project.
The Kiro driver adds the recorded skills to each status check and republishes the snapshot when they change. Skill paths use acp://skill/<name>, as for ACP registry skills.
The Kiro flavor's rewriteUserText turns a leading $name into /name when name is a skill Kiro advertised. Other $ text is sent unchanged, and the stored user message keeps $name.
docs/user/providers-kiro.md gets a short Skills section: skills appear after a Kiro session has started, project .kiro/skills are not listed, and a skill must start the message.
Focused tests (vp test run), all passing on this head; the first three failed on main:
apps/server/src/provider/KiroProvider.test.ts › "lists the skills a Kiro session advertises": a real KiroDriver instance whose Kiro session sends a skill; waits on the snapshot stream until the skill is listed.
apps/server/src/orchestration-v2/Adapters/KiroAdapterV2.test.ts › "sends a $ skill mention as the /command Kiro runs": $probe-skill rest reaches session/prompt as /probe-skill rest.
Same file › "keeps advertised skills through an update without skills".
packages/provider-kiro/src/server/skills.test.ts: skill-only filtering, case-insensitive dedupe, workspace skills left out, merge across sessions, and that $deployer, $25 and run $deploy stay text.
The three files passed 8 consecutive runs (40/40 each). vp run check:changed passes (45 tests).
Real app, web dev server on a fresh database, Kiro instance pointing at the real kiro-cli 2.37.1 with a placeholder API key (the session starts and advertises skills; the model call itself fails with "Kiro could not load the available models…" because the key is not real):

Kiro actually running a skill end to end, which needs a signed-in Kiro account.
Pixel-paired native (Android) before/after stills: the native recordings show the menus, but the live OS clock and keyboard state differ between runs.
The "Show skills in slash menu" setting switched back on in the same recording (it was captured off, then the menu returning); that setting is unchanged by this PR.

These tests reproduce #31645 and fail on main:
- KiroProvider: a Kiro session's available_commands_update with a
`_meta.kiro.type: "skill"` command never reaches the instance snapshot,
so `skills` stays empty.
- KiroAdapterV2: a turn starting with `$probe-skill rest` reaches Kiro's
session/prompt unchanged (wrapped in T3 instructions) instead of as the
`/probe-skill rest` command Kiro runs.
AI-assisted; verified with the tests and tools listed above.
Kiro sends a session's skills only as `available_commands_update` entries
with `_meta.kiro.type: "skill"`, and the Kiro flavor ignored that update, so
the composer's `/` and `$` menus never listed them. Kiro also runs a command
only from a leading `/name`, while T3's picker inserts `$name`.
Each Kiro instance now keeps the latest advertised skills in a
SubscriptionRef. The adapter writes it from `onAvailableCommandsUpdate`;
the driver adds it to every status check and republishes it through
`enrichSnapshot`, so a later check no longer clears it. Names are bounded,
deduped and given an `acp://skill/<name>` path like ACP registry skills.
`rewriteUserText` turns a leading `$name` into `/name` only for an
advertised skill; other `$` text is sent unchanged.
Fixes#31645
AI-assisted; verified with the tests and tools listed above.
Kiro sends several available_commands_update notifications per session,
and the first carries only custom agents. Each one replaced the instance's
skill list, so the menus blanked on every session start, a `$skill` first
message could go out unrewritten, and one session's skills replaced
another's.
The instance store now merges each update's skills by case-insensitive
name (a newer entry replaces the older one in place, new ones append up
to the existing cap) and publishes only when something changed. The menus
and the `$name` -> `/name` rewrite both read that store. The Kiro guide
gains a short Skills section.
AI-assisted; verified with the tests and tools listed above.
Kiro also advertises a project's `.kiro/skills` (origin "workspace" with a
root), and the instance-wide store offered and rewrote those in every other
project. The store now records only skills Kiro does not scope to a
workspace, and the user guide says project skills are not listed.
The skill tests now wait for the skill to reach the store or the instance
snapshot before acting, instead of relying on replay order or reading the
snapshot after the turn.
AI-assisted; verified with the tests and tools listed above.
Macroscope's review found this PR approvable — Kiro's advertised global skills now appear in the command menus, with leading skill mentions translated into Kiro commands. The bounded, in-memory catalog excludes workspace skills and does not change provider defaults or permissions.

Walkthrough
The Kiro provider now records eligible skills from command updates, publishes them in provider snapshots, and rewrites matching leading skill mentions in prompts. Tests and provider documentation cover skill discovery and use.

Summary
Skill collection and command-text rules packages/provider-kiro/src/server/skills.ts, packages/provider-kiro/src/server/skills.test.ts, packages/provider-kiro/src/testing.ts
Adds skill filtering, deduplication, merging, and command-text rewriting. Tests cover eligible skills, update behavior, and mention matching. The testing module re-exports the skills store type and constructor.
Adapter command and prompt handling packages/provider-kiro/src/server/adapter.ts, apps/server/src/orchestration-v2/Adapters/KiroAdapterV2.test.ts
The adapter records available commands and rewrites prompt text using the skills store. Tests verify that a matching leading skill mention is rewritten after an ACP command update.
Snapshot publication and provider validation packages/provider-kiro/src/server/driver.ts, apps/server/src/provider/KiroProvider.test.ts, docs/user/providers-kiro.md
The driver includes current and updated skills in provider snapshots and passes the store to the adapter. Integration tests verify that an advertised skill appears as enabled. Documentation describes skill availability and behavior.
pingdotgg/t3code#19572: Both PRs affect handling of slash-leading prompts; this PR rewrites a leading advertised $skill mention to /skill before sending it to Kiro.
pingdotgg/t3code#27123: Its provider skill catalogs can use the Kiro skills added to snapshots by this PR.
pingdotgg/t3code#14693: This PR extends the Kiro provider and ACP adapter introduced there.
Merge Risk: Low · up to 2252f
There is no established production issue blocking the Kiro skills change. The remaining concern is how the adapter test is organized; it can be addressed as a follow-up.

Explanation
[#31645] The Kiro adapter records advertised skill commands. The driver publishes them in provider snapshots with acp://skill/<name> paths. The adapter rewrites a leading $name to /name for an advertised skill, which matches Kiro's command format. The tests cover snapshot publication, rewriting, and persistence when a session update has no skills. The change also excludes workspace-scoped skills and documents the behavior.

Keep the ACP ordering coverage, but fold it into the existing adapter test.
The lower-level test covers recordKiroSkills directly. The first adapter test covers only one notification. This test uniquely exercises multiple available_commands_update notifications through the ACP adapter and proves that an agents-only update does not remove the earlier skill. Deleting it would leave a dropped or misordered subsequent update undetected.
Extend the first adapter test with these frames and assertions instead of deleting this coverage.

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.
Checked kiro-cli --version, then kiro-cli whoami --format json. Observed kiro-cli 2.37.1 and {"account":null}, with whoami exit code 1. Stopped before session creation because no signed-in Kiro account was available. Neither side's composer interaction was executed.
+1, seeing this with kiro-cli 3.2.0 on the 2026-11-11 nightly. I have 47 global skills in ~/.kiro/[skills](https://github.com/home/vinay/.kiro/skills), and $ shows "No skills found". ~/.t3/caches/[kiro.json](https://github.com/home/vinay/.t3/caches/kiro.json) has "skills": [] and only compact in slashCommands.
I'm signed in to Kiro, so I can test this branch end to end if that would help get past the gate.
