feat(web): auto-reconcile external agent sessions on project open - #10969
feat(web): auto-reconcile external agent sessions on project open#10969lewismarshall wants to merge 3 commits into
Conversation
When environment shells bootstrap, automatically import external Claude Code and Codex sessions for every known project. This surfaces agent work already on disk in the thread list without requiring a manual "Import agent sessions…" action. The new useAgentSessionAutoReconcile hook reuses the existing idempotent agentSessions.import RPC. Each project is reconciled once per mount cycle; failures are silently ignored since a missing agent home is not actionable for the user. Refs: pingdotgg#6994, pingdotgg#6680 Co-authored-by: Lewis Marshall <lewismarshall@users.noreply.github.com>
The original hook swallowed all import failures silently (.catch(() => {})),
making E2E debugging impossible when the server doesn't support the
agentSessions.import RPC (e.g. t3@0.0.38 predates PR pingdotgg#5362).
Changes:
- Add classifyImportFailure() that distinguishes four failure kinds:
unsupported-server (RpcClientError), interrupted, expected domain
errors, and unexpected defects.
- Log unsupported-server with a one-time console.warn naming the
required server version and PR pingdotgg#5362. Skip further import attempts
for that environment.
- Log expected errors (project not found, workspace mismatch, scan
error, auth) with console.warn including project context.
- Log unexpected errors with console.error for debugging.
- Log successful imports with console.info when importedCount > 0.
- Add 10 new unit tests for classifyImportFailure covering all
error classifications.

selectUnreconciledProjects no longer eagerly adds keys to the reconciled set. The hook marks a project reconciled only after: - A successful import (importedCount + skippedCount returned). - A definitive domain error (project not found, workspace mismatch, scan error, auth error) — these won't resolve without user action. Transient failures (unsupported-server, unexpected defect, interrupted) leave the project eligible for retry on the next render cycle. This fixes the scenario where imports fail against an old server (pre-pingdotgg#5362) and the project is permanently marked done, preventing retry after a server upgrade without a full client remount. Also: console.info now logs for every successful import (even when importedCount is 0) with projectId, workspaceRoot, and skippedCount for E2E observability.

🟡 Medium hooks/useAgentSessionAutoReconcile.ts:66
A temporary socket or HTTP failure is classified as unsupported-server, so line 149 permanently adds the environment to unsupportedServersRef and skips every later project in that environment for the rest of the mount, preventing session imports after reconnection. isRpcClientError covers transport failures as well as an unsupported method; classify only the specific “method not found” error as unsupported-server and leave transport errors retryable.

After agentSessions.import reports an unsupported server, every project in that environment is skipped for the rest of the mounted ChatRouteLayout, so reconciliation never resumes after the server is upgraded or reconnected. The marker in unsupportedServersRef is never cleared; clear it when bootstrapping is lost so the next bootstrap retries the import.

ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR changes project opening from a passive flow into an automatic external-session reconciliation workflow that can scan agent history and persist imported threads across all known projects. Its reconnect and server-compatibility behavior also has unresolved operational risks that merit human validation. Not approved because:

Restrict "unsupported-server" to the not-implemented error. RpcClientDefect also represents socket closure and protocol failures. The current check therefore adds the environment to unsupportedServersRef and disables auto-reconcile for the mount. Inspect the RPC error’s not-implemented signal before returning "unsupported-server". Classify other RPC failures as "unexpected" so they remain retryable.

Bound retries for unexpected import failures.
projectsAtom preserves the array across ordinary renders, but an "unexpected" failure remains unreconciled. Each later projects update can issue another agentSessions.import and log another error. Add a per-project retry limit and delay.

What Changed
Added always-on automatic reconciliation of external agent sessions (Claude Code, Codex) when projects become available on a connected environment.
A new
useAgentSessionAutoReconcilehook is mounted in the chat layout route. When environment shells bootstrap, it calls the existing idempotentagentSessions.importRPC for every known project, surfacing agent work already on disk in the thread list — without requiring a manual "Import agent sessions…" action.Related Ideas discussions:
