Hooking the rescan to the first One thing I'd change before merge. In ProviderRegistry.ts around line 934, Small one: the description still says the ClaudeDriver.ts link has no test, but the new ProviderInstanceRegistryLive.test.ts case covers it through the real driver now. |

Thanks @JonasFocus, both done.

This branch has not been deployed

Problem
Fixes #14801.
For a new-worktree thread the composer asks for a workspace snapshot of the worktree as soon as
git worktree addfinishes, before any Claude session exists.refreshWorkspaceSnapshotreturns early for a cwd it has already scanned unlessfreshis set, and the composer stops asking once a snapshot exists. So project skills that appear in<worktree>/.claude/skillsonly after creation (for example a gitignored folder that a SessionStart hook symlinks in) never reach the$picker. Only "Restart agent session" passesfresh: true; nothing on the automatic path rescans.Confirmed on current
main(cc1e634bfa, after the orchestrator rewrite in #2829): the only caller ofrefreshWorkspaceSnapshotis theserverRefreshProvidersRPC, and nothing underorchestration-v2/calls it or reports a started session to the registry.Change
The Claude adapter now reports the query's cwd to its driver the first time the CLI sends
initfor a query.initcomes after the SessionStart hooks (the recorded transcripts underorchestration-v2/testkit/fixtures/showhook_started,hook_response, theninit). The driver puts that cwd on a new optionalProviderInstance.workspaceRescansstream, and the registry rescans each cwd the stream emits, replacing the held snapshot. The updated snapshot reaches clients through the usual provider change stream.initon every turn of one process (the multi-turn fixtures have twoinitframes and one hook run), so a flag on the live query context limits it to the first one. A new query (new process, hooks run again) reports again.fresh: afreshscan also invalidates caches, re-probes the whole Claude installation and drops other instances' snapshots for the cwd. Doing that at every session start is more than this needs, sorefreshWorkspaceSnapshotgets an internalrescanflag. It skips the "already scanned" early return and the join onto a running scan. TheProviderRegistryservice shape and the wire contracts are unchanged.freshscans keep. It does not win over a scan that started after it: scans carry a start counter, the registry remembers the newest committed start per instance and cwd (capped at 16 cwds, like the snapshots), and a rescan whose start is older than that is dropped.updateProvidersandrefreshWorkspaceSnapshotmoved abovesyncLiveSourceswith no other change to them. The rescan consumers forked there can already have a report waiting in the queue, and they must not find either one uninitialized. Most of the diff inProviderRegistry.tsis this move.workspaceRescansfield is optional, so any of them can adopt it with its own session-ready signal. I did not check whether they have the same gap.Related but not touched: #11575 (the
/menu frozen on the placeholder probe), #13077 and #13251. #13251 editsrefreshWorkspaceSnapshot's neighbourhood inProviderRegistry.tsand the driversnapshotForCwdentries; this change adds a field and a flag in the same files, so whichever lands second may need a small rebase.Scope and approval
Bug fix for #14801, which the maintainers triaged ("Your reading is right, and it reproduces from source on current
main", with the likely fix named as rescanning once the session is up and hooks have finished). It does not change product behavior beyond making the picker show skills that already exist on disk.Verification

ClaudeAdapterV2.test.ts"reports the session cwd once per query": before,expected [] to deeply equal [ '/synthetic/worktree' ]; after, passes. The firstinitof a query reports the query's cwd (not the resolved path in the frame), and a secondiniton the next turn does not report again.ProviderRegistry.test.ts"rescans a held workspace…": before, the test timed out because the snapshot never updated; after, passes. A realdiscoverClaudeSkillsscan of a temp worktree finds no project skill, the skill is written, a normal refresh leaves the snapshot alone, then the instance emits the cwd and the held snapshot listsdeploy, without invalidating caches.ProviderRegistry.test.ts"lets a rescan overwrite the snapshot of an older scan that committed first": with the override disabled the test fails; with it, passes. The older scan commits first, then the rescan, and the rescan's skills are the ones held. Dropping the "first scan still running" exemption from the guard below also fails this test, so that exemption is needed.ProviderRegistry.test.ts"does not scan a rescan for a cwd no client asked about": without the guard it fails withexpected [ '/requested', '/unrequested' ] to deeply equal [ '/requested', '/requested' ]; with it, passes. A rescan for/unrequestedis not scanned and adds no entry, while a rescan for a held cwd still is.ProviderRegistry.test.ts"keeps a fresh scan that started after a rescan when the rescan finishes last": the rescan starts, a fresh scan starts later and commits first, the rescan finishes; before, the held skills ended up the rescan's (expected [ 'rescan' ] to deeply equal [ 'fresh' ]); after, the fresh scan's stay.ProviderRegistry.test.ts"serves a session start reported before the registry finished building": a report is already in the instance's queue when the registry is built. Before the move the consumer never recovered (test timed out), after it a later rescan is served.ProviderInstanceRegistryLive.test.ts"keeps a Claude session start reported before anyone listens and ends with the instance": runs the real driver with a mocked query runner, so it covers the link between the adapter'sinitreport and the stream. The report is made before anything subscribes and is still delivered; against an earlierPubSubversion it timed out. Removing the instance ends the stream; without the finalizer it times out.Neighbouring files, all passing:
