Problem

After a Claude thread's workspace snapshot is evicted by scans of 16 other folders, its $ picker temporarily shows only personal skills. Project skills wait for a fresh Claude capability probe even though filesystem skill discovery has already finished.

Change

Publish discovered Claude workspace skills before the capability probe, with slash commands pending. Partial and final results use the same registry ownership and freshness guards. The final result replaces its own partial publication; the 16-workspace cap remains.

Other providers keep their existing one-result discovery path. No wire schema or client rendering changes.

Scope and approval

Fixes https://git.cafe/pingdotgg/t3code/issues/22429
GitCafe: https://git.cafe/pingdotgg/t3code/issues/22429
Triaged bug via the automated issue flow. One reproduced cache-eviction timing defect; no authentication, permission, mode, sandbox, or MCP changes.

Verification

  • Main reproduction: 17 real worktrees of one repository, each with a project-only Claude skill. Returning to the first after scanning the other 16 temporarily showed personal skills only; repeated with a filtered skill query.
  • Red test committed before the fix: the registry had no project skills while a Deferred held command discovery after eviction. After the fix, the same test observes skills with commands pending, then final commands and cleared pending state.
  • Post-merge vp run check:changed: formatting, targeted lint, Knip, generated GraphQL verification, affected-package typechecks, and the full registry test file (38/38) passed.
  • Additional implementation checks: Codex/Antigravity discovery test files (29/29), Pi driver tests (5/5), server and provider-core typechecks passed.
  • Two isolated code reviews returned MERGE. The actual PR diff after merging current main is byte-identical to the reviewed diff.

Evidence matrix

Before: beec3c8b30ce. After: 26c41f4c7fa8.

Formal static render matrix: empty ([]). The changed paths are server/provider internals; the four rows below are supplemental interaction recordings. No still-image/pixel-diff claim is made. The pass-1 matrix and audit are in the linked support bundle; independent pass-2 proof audit passed all six required evidence rows.

Viewport / theme Before After
1440×900 / light Before 1440px light: full real-app eviction and picker flow After 1440px light: full real-app eviction and picker flow
1440×900 / dark Before 1440px dark: full real-app eviction and picker flow After 1440px dark: full real-app eviction and picker flow
390×900 / light Before 390px light: full real-app eviction and picker flow After 390px light: full real-app eviction and picker flow
390×900 / dark Before 390px dark: full real-app eviction and picker flow After 390px dark: full real-app eviction and picker flow

Script and observed ordering

Same 17 stopped fixture threads and project skill on both isolated servers. A is folder 02. Prime A, type $triage, visit 03–17 then 01 sequentially and await each real settled snapshot, prove A absent with 16 cached folders, return A within 15–21 seconds, keep $triage visible through discovery, then show / and query /compact. No turns sent. The actual /compact query suggests /autocompact on both sides; the unchanged final provider snapshot contains 70 command names.

Before: the project row is missing while the personal skill remains, then appears only after final command publication. After: the project row becomes visible with slashCommandsPending:true, 448–744 ms before final publication in these runs. A brief filesystem-discovery gap remains; this eliminates the slow CLI interval, not every millisecond of absence. All recorded snapshot lists stay at or below 16.

Width / theme Before: pending at project visibility After: project visible before final publication
1440 / light No 562 ms; pending=true
1440 / dark No 744 ms; pending=true
390 / light No 448 ms; pending=true
390 / dark No 573 ms; pending=true

Rebuild, transcript and audit metadata

Rebuild guide · Support bundle: scripts, fixture creation data, pass-1 audit/matrix, provenance, probe spans, red/green logs · Ordered live runtime transcript · Capture audit metadata

The transcript subscribes to the real appAtomRegistry / serverEnvironment.providersValueAtom and observes actual DOM mutations. It records cwd, skill/pending/count milestones and the final real command names. Server workspace-probe spans are correlated by timestamp; they lack cwd attributes and an independent CLI subprocess span, so no exact CLI launch/completion claim is made. Parent-provided green log labels the final head and reports 38 focused tests passing. Historical red output lacks an in-band invocation/SHA; its provenance limit is retained in metadata.

What else changed and rendering

The intended visible difference is the transient project row during discovery. Final command names match across all eight runs. Live age badges differ with capture time, and caret/text selection plus recording frame sampling vary while typing; no pixel-identity claim is made. The same responsive route navigation, viewport, theme, fixture, provider and scroll position are used per pair. Sidebar filtering hides unrelated threads; update notifications were dismissed. A02 avoids a separate active A01 client refreshing its own evicted cwd.

Tool/browser: T3 collaborative Browser, Chrome 154 on Linux. No device emulation; freeform 1440×900 or 390×900 CSS viewport, DPR 2, visual viewport scale 1, root font 16px, text-size-adjust 100%. Complete native viewport footage is 2880×1800 or 780×1800. A 240-native-pixel caption band sits outside the app; the original recording is uncut and retains its speed, with a labelled four-second final-frame hold. Captions narrate script and browser-clock milestones; compositor/video frames are not perfectly synchronized to DOM subscription timestamps. No artificial provider delays, fake snapshots or synthetic component fixtures were used.

Served Vite source-map originals for five relevant runtime/client files per checkout match the exact git refs. Server cwd/start times and observed partial/final behavior support runtime provenance; no in-process build hash endpoint exists. The before server predates the merge-base checkout, but all four changed runtime files are byte-identical between its original base and the final base.

Limits and publication

Native iOS/Android, desktop shell, remote/relay and multi-device runtime timing remain unverified. Clean-room reseeding was not executed: rebuild scripts were syntax/source checked and captures reused the parent’s fixture. Personal skill source files and unrelated data are excluded. Independent pass-2 proof audit passed; this is evidence for review, not merge approval.

Before upload, both required cafe issue reads succeeded with zero comments and complete pagination; no recent MEMBER/OWNER comment existed. No repository edits, commits, pushes, issue/PR writes, new dev servers or agent turns were made by this capture task.

Unverified: Electron shell, native iOS/Android, remote/relay/tunnel, multi-device, cancellation and instance replacement at runtime. Their code paths are unchanged. Filesystem discovery still takes its normal time; this removes the wait on the slow command probe.

Implementation: Claude Opus 5.5 via Claude Agent SDK; triage, integration and evidence: GPT-6.1-Sol via Codex; independent code/proof reviews: GPT-6.1-Sol via Codex and Claude Opus 5.5 via Claude Agent SDK.

…and probe

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A workspace pushed out of the 16-entry snapshot list fell back to the
machine's personal skills until Claude's slow capability probe finished.
Drivers can now hand the registry a partial snapshot; Claude publishes its
on-disk skills before starting the probe, under the same refresh ownership
checks as the final result.

Walkthrough

Claude workspace scans can publish discovered skills before command probing completes. The registry can return a pending snapshot while the scan continues. Client refresh logic retries pending snapshots and stops when provider state updates with a complete snapshot.

Changes: Workspace snapshot updates

Layer / File(s) Summary
Claude partial snapshot publication
packages/provider-core/src/server/driver.ts, apps/server/src/provider/Drivers/ClaudeDriver.ts, apps/server/src/provider/ClaudeProvider.ts
The provider interface and Claude driver pass an optional callback to Claude probing. Claude publishes discovered skills through the callback before capability probing.
Registry partial and final results
apps/server/src/provider/ProviderRegistry.ts, apps/server/src/ws.ts, apps/server/src/provider/ProviderRegistry.test.ts
The registry publishes partial and final snapshots through guarded checks. Callers can return on the first partial result without stopping the scan. The WebSocket refresh requests this behavior for on-demand snapshots. The test covers concurrent refreshes, eviction, and completion of a pending scan.
Client retry for pending snapshots
packages/client-runtime/src/providerSkills.ts, packages/client-runtime/src/providerSkills.test.ts
The client retries a pending snapshot immediately once, then uses the existing cooldown and attempt limit. The test verifies that scanning continues until provider state updates with a complete snapshot.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: Low · previous review ae2f5

Project skills now appear before slash-command discovery finishes, which addresses the main report. Two narrow edge cases remain. A second request that arrives before the first partial result still waits for the full probe. Under heavy concurrent worktree use, a final result can be dropped after its partial snapshot is evicted, and the client then rescans. Both are limited in scope and have safe fallbacks, so the change is mergeable with these gaps known.

Full details: Title check

Explanation

The title follows conventional commit form and names the main change: Claude project skills become visible before command discovery finishes. The raw summary shows the server publishes partial workspace snapshots with slash commands pending, which matches the title. The title is concise and specific, and it does not describe anything absent from the changeset.

Full details: Description check

Explanation

The description follows the template. It has Problem, Change, Scope, and Verification sections, and it links the issue (#22429). The Problem and Change sections are clear and specific. The Scope section links the issue and explains the bug-fix basis. The Verification section lists focused tests, a red-then-green regression test, and manual reproduction results. The description is long and includes extra material such as hosting links, an evidence matrix, and provenance notes. The template asks for concise content, so this extra material is noise, but the required information is present. The description also has a conflicting claim: the objectives say the automated pipeline stopped the PR because the reproduction failed, while the description reports a reproduced defect. The description does not address that conflict. Both points are noted here, but neither prevents the template check from passing.

Full details: Linked Issues check

Explanation

Issue #22429 requires that project skills for an evicted Claude workspace remain visible during rescan, or that the previous list stays visible. The change publishes discovered workspace skills before the Claude capability probe in probeClaudeWorkspaceSnapshot (ClaudeProvider.ts) and sets slash commands pending. ProviderRegistry.refreshWorkspaceSnapshot (ProviderRegistry.ts) publishes partial results with the same instance, scan-token, and freshness guards, then publishes the final snapshot. ProviderRegistry.test.ts covers eviction with pending commands, a concurrent request joining the scan, and final command publication. providerSkills.ts retries once without cooldown when a snapshot has slashCommandsPending. The 16-entry cap is not changed in the summary. The issue names this publish-before-probe approach as an option, so it satisfies the requirement. A brief filesystem-discovery gap remains, as the PR states. This is within the issue's expected behavior. Native, remote, and multi-device runtime behavior is not verified and is not required by the issue's coding criteria. The PR comment about reproduction failure does not change the coding requirement.

Full details: Out of Scope Changes check

Explanation

Each changed area supports the partial-publication path for #22429. ClaudeProvider.ts and Drivers/ClaudeDriver.ts pass a publishPartial callback. packages/provider-core/src/server/driver.ts adds the optional callback to the snapshotForCwd interface. ProviderRegistry.ts adds untilPartial and partial publication. ws.ts enables untilPartial only for cwd-specific on-demand refreshes. packages/client-runtime/src/providerSkills.ts and its test handle the pending-command retry. ProviderRegistry.test.ts covers the new behavior. The summary shows no changes to authentication, permissions, modes, sandboxing, MCP, rendering, or other providers' completion path. The untilPartial option is internal and does not change the wire schema, as the PR states. No unrelated change is demonstrated.

🟠 High provider/ProviderRegistry.ts:1007

When this scan’s partial snapshot is evicted by later workspace scans, its final result is discarded, so the workspace never receives the completed inventory or discovered commands. publishedFrom still points to the evicted snapshot, causing this equality guard to reject the now-missing entry even though this scan still owns the refresh token; allow the scan to publish when its entry has been evicted.

Preserve the final publish after partial snapshot eviction.

If 16 other workspace snapshots are published while Claude probes commands, they can evict this scan's partial snapshot. The final publish then compares undefined with publishedFrom and drops the result. Waiting callers receive no snapshot for this cwd; a later request can start another scan.

Before this change, a scan that started without a snapshot could publish its final result in this case. Distinguish eviction from explicit invalidation so the final publish can proceed without restoring an invalidated snapshot.

Extend the eviction test to publish 16 other cwd snapshots after the partial publish, then release the probe and assert that the final snapshot is stored.

Review comment at @apps/server/src/provider/ProviderRegistry.ts at line 1009:
Update the final-publish guard in the scan flow around `workspaceSnapshotOf(candidate)` to distinguish capacity eviction from explicit invalidation. Allow the final result when the scan’s partial snapshot was evicted, while continuing to reject results invalidated explicitly; extend the eviction test to publish 16 other cwd snapshots before releasing the probe and assert that the final snapshot is stored.

Test partial publication by the Claude probe.

The registry test supplies its own snapshotForCwd, so it would pass if this publication call were removed. Add a test for probeClaudeWorkspaceSnapshot that holds command discovery open and asserts that discovered project skills reach publishPartial before the probe completes.

… evicted

A partial publication moved the scan's freshness baseline to the partial
entry, so evicting it under the 16-workspace cap made the final result
look stale. Accept the scan's start state as well, as main does.

AI-assisted; verified with the tests and tools listed above.
Clients that fetch workspace snapshots on demand see a folder's snapshot
only in the refresh reply, which waited for the command probe. The
scan's owner now replies once partial skills are published, and the
client asks again at once to join the running scan for the commands.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Hold the complete reply until the partial snapshot is visible.

Both replies settle in the same timer flush. The stub never stores either reply in providersAtom. As a result, the scanning assertion remains true after the complete reply only because the atom still contains noSnapshot. The production command records each successful snapshot before it returns. This test cannot detect a regression that hides partial skills until probing ends. Defer the complete reply. Store the partial snapshot and assert that its skills are visible while scanning continues. Then release and store the complete reply, and assert that scanning stops. (raw.githubusercontent.com)

As per path instructions, “Test behavior that can break, including orchestration, race fixes, and the logic changed by a bug fix.” Based on learnings, tests of asynchronous ordering should use a controllable mechanism that permits assertions between settlements.

Honor untilPartial for callers that join before partial publication.

If two on-demand requests arrive before skill discovery finishes, the second request takes this branch. It waits for the complete capability probe even when untilPartial is true. Its client cannot receive the discovered skills through the config stream because apps/server/src/ws.ts, Lines 3370–3378, removes workspace snapshots.

Store the first-partial signal with the in-flight token. Let callers that join before partial publication wait for that signal or completion. Callers that join after partial publication can continue waiting for completion, as the follow-up request requires.

Extend the existing deferred-probe test with a second untilPartial: true request before partial publication. Verify that both requests receive skills before releasing the probe.

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.

On each commit, opened workspace A and typed $project-proof, confirming the project-only skill appeared. Visited the other 16 worktree threads sequentially, waiting for each workspace discovery to settle. Returned to A after 8.374 seconds on base and 9.930 seconds on head, reopened the same filtered picker, and observed it for eight seconds. The project skill appeared immediately on both commits. Both clients retained 17 workspace snapshots, including A; commands were not pending on return. The supplied reproduction did not trigger the eviction/rescan condition.

It stays open for a person to finish or close.

… retry budget

An early partial reply now makes the next request join the running scan without counting as a failed attempt. Only the joined reply counts, so a transient probe failure followed by a slow successful probe still delivers the final commands to on-demand clients.

…plies

Every on-demand client sets workspaceSnapshotsOnDemand, including builds without the joining retry, which treat a pending reply as a failed attempt and wait out the cooldown. The early reply is now gated on a new acceptPartialWorkspaceSnapshot request flag that only the updated refresh atom sends; older clients wait for the full scan as before.
