Agents share a library of named specialists across connected environments. Each agent has model defaults and frozen instructions for its chats; the board provides chat creation, hover replies with attachments, PR links, and settlement after merged work.

Agent profiles now include an optional 280-character specialization displayed beneath the name and exposed through MCP. t3_get_agents_view returns agents and their run summaries for a granted environment, supports profileId and active/settled/all filters, and retains runs belonging to deleted agents. t3_list_agents remains available for profile discovery; MCP create/update can set or clear descriptions.

Upstream sync

Includes upstream main 68c2277f50 (and nightly v0.0.41-nightly.20260912.1612) plus contributor PR jayleaton#3, which ignores isolated .t3-run/ state. Conflicts are resolved while retaining upstream message contexts, composer controls, settings, and license routes. Migration 52 repairs existing agent builds that already used upstream migration numbers, preserving frozen profiles and PR storage.

Validation

  • Web, server, client-runtime, and MCP gateway scoped typechecks passed; changed feature files passed scoped lint.
  • 102 MCP tests passed, including the real MCP transport, description lifecycle, run grouping/filtering, and read-grant enforcement. Focused settings, projection-query, migration, and agent-dialog tests passed.
  • An isolated web app using a snapshot of local data successfully saved, reopened, and cleared a specialization. The copied database upgraded to migration 52, retained 28 frozen agent chats, and passed SQLite quick_check.
  • Mac ARM64 Nightly 0.0.41-nightly.20260913.9001 built successfully. Its packaged Electron runtime initializes the bundled MCP companion and lists all 59 tools, including the Agents board and description schema. Strict deep code-sign verification passes; the artifact contains the expected production sign-in/relay configuration. Installed locally with a backup retained; relaunch verification follows. Remote-machine deployment and native mobile behavior are not covered by this update.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR introduces a broad Agents and MCP platform spanning UI, server orchestration, authentication, desktop packaging, filesystem state, webhooks, and repository operations. The scope and side effects are substantially beyond a bounded additive change and require human review.

Not approved because:

  • Per-review cost limit exceeded (workspace setting). Approvability relies on correctness review in order to determine eligibility

Merge Risk: 🔵 Low · up to 1c533

This change adds shared agent workflows and MCP gateway controls across server, desktop, and web clients. Bounded risks remain around error feedback, gateway lifecycle behavior, transport limits, and a few platform or UI edge cases, but no evidence indicates a likely severe outage, data loss, or security failure.

Handle a storage failure when the token blur handler saves.

setMcpGatewayToken writes to browser storage. The adjacent handlers for the enable switch (Lines 566-576) and the bridge port (Lines 594-602) wrap the same class of call in try/catch and set configurationError. This handler does not. If storage access is denied, the write throws inside a React event handler, the user receives no feedback, and the token appears saved. Apply the same guard.

Handle a rejected updateSettings in the delete handler.

Resolve on the configured message instead of a 10 ms timer.

authenticate sends configure and then resolves after a fixed 10 ms abort. The bridge sends a configured acknowledgement, so the timer adds no guarantee. If the bridge has not applied the grants yet, callers that await authenticated continue too early. Line 102 then expects bridge.port.listEnvironments() to resolve, and it rejects with "No configured T3 client" instead. Wait for the acknowledgement message to remove the race.

An enable() during an in-flight disable() is dropped.

disable() bumps the generation at line 66 but leaves current at { state: "running" } until every stop() resolves. If enable() runs during that await, line 34 sees an active runtime, returns "running", and starts no runtime. When disable() then completes, it sets { state: "disabled" } and clears handles. The gateway stays off, and the enable() caller received a status that never became true.

Track shutdown explicitly so enable() can wait for it instead of returning early.

creation.

In `@packages/client-runtime/src/state/sharedSettings.ts`:
- Around line 29-30: Update filterSharedServerPatch to remove mcpGatewayProfiles
and mcpGatewayProfileDeletedAt unless agentLibrarySync is true, while preserving
existing filtering behavior. Also gate replicateProfiles requests on
agentLibrarySync so unsupported environments are excluded.

In `@packages/contracts/src/rpc.ts`:
- Around line 523-527: Restrict the replicateProfiles path in
WS_METHODS.serverUpdateSettings and its apps/server serverSettings handler to a
replication-only authorization scope, or remove the flag from the ordinary
settings RPC. Ensure ordinary clients cannot trigger
ServerSettingsService.updateSettings with caller-supplied replication
timestamps, revisions, or deletion metadata; update both
packages/contracts/src/rpc.ts lines 523-527 and
apps/server/src/serverSettings.ts lines 357-367 as needed.

In `@packages/mcp-gateway/src/deliver.ts`:
- Around line 153-162: Update deliverBatch to track delivery rows already
examined during the current batch and skip them on subsequent dueDeliveries
results, including rows rejected by authorization or returning undefined from
store.buildDelivery. Ensure each row is visited at most once so the attempted
&lt; batchSize loop terminates without changing successful delivery handling.

In `@packages/mcp-gateway/src/sharedOwner.ts`:
- Around line 77-79: Gate the bridge callbacks in createBridgeRuntimePort until
the events store is initialized, preventing getEventCursor, onEvent, and
getStatusSnapshot from invoking store() during the startup interval. Buffer or
defer callback work until readiness, while preserving bridge startup before
store creation to avoid opening SQLite after losing the owner race.

Minor comments:
In `@apps/desktop/src/mcpGatewayCredential.ts`:
- Line 59: Update the credential file validation around the POSIX mode check to
apply ownership and permission checks only when source.userId is not null.
Preserve the existing rejection behavior on platforms with a user ID while
allowing Windows synthetic file modes.

In `@apps/server/src/provider/acp/AcpSessionRuntime.ts`:
- Line 693: Update the initialize metadata construction around
options.initializeMeta to include _meta whenever initializeMeta is not
undefined, preserving an explicitly provided null value while still omitting the
property when no value is supplied.

In `@apps/server/src/provider/Layers/ProviderService.ts`:
- Around line 343-346: Update the cwd initialization in the
sendTurn/session-start flow to check thread.value.worktreePath first and call
projectionQuery.value.getProjectShellById only when it is absent. Preserve the
existing project.workspaceRoot fallback when no worktree path is available.

In `@apps/web/src/components/agents/AgentChatPreview.tsx`:
- Line 67: Update the truncation-note condition in AgentChatPreview so it
compares the full detail message count against the count of visible, non-system
messages retained by the preview, rather than messages.length alone. Ensure the
note appears only when earlier visible history was actually omitted, while
preserving the existing last-8 message filtering behavior.

In `@apps/web/src/components/agents/AgentsBoard.tsx`:
- Around line 346-361: Update the delete handler’s updateSettings flow in
AgentsBoard so rejected promises are caught, set the existing delete error
message, and keep the dialog open; preserve the current success handling and
busy-state cleanup in finally.

In `@apps/web/src/components/settings/McpGatewaySettings.tsx`:
- Line 619: Wrap the token blur handler’s setMcpGatewayToken call in the same
try/catch pattern used by the enable-switch and bridge-port handlers, and set
configurationError when storage persistence fails. Preserve the existing token
save behavior when no error occurs.

In `@packages/mcp-gateway/src/bin.ts`:
- Around line 33-53: Move parseGrants and all startup environment validation
into the existing try/catch in bin.ts so validation failures use the formatted
t3-mcp-gateway error path and shared-owner processes can report the actual
validation message. Update parseGrants to validate that the parsed JSON is a
non-null object before calling Object.entries, rejecting primitive and null
values while preserving valid grant-map handling.

In `@packages/mcp-gateway/src/bridge.test.ts`:
- Around line 65-69: Update the configure branch in authenticate to resolve only
when the bridge receives its configured acknowledgement message, removing the
fixed AbortSignal.timeout(10) timer. Preserve the immediate resolve path when
configure is false and ensure the acknowledgement listener resolves exactly
once.

In `@packages/mcp-gateway/src/lifecycle.ts`:
- Around line 34-35: Update the lifecycle state around enable() and disable() to
track an in-flight shutdown explicitly: assign a stopping promise at the start
of disable(), clear it in a finally block, and make enable() await that shutdown
before deciding whether the runtime is already active or starting a new runtime.
Preserve the generation and handle cleanup behavior while ensuring an enable()
during disable() results in a running runtime.

Review follow-up pushed in 252bcba.

Verified all 12 inline findings and the nine minor findings against the current implementation. The changes fix webhook progress/shutdown, lifecycle error receipts and source-message capture, status-cache invalidation, bounded live event retention, rejected handoffs, older-server agent synchronization, Windows credential modes, rapid disable/enable handling, and UI storage/delete errors. Smaller fixes preserve explicit null ACP metadata, correct the preview history note, avoid an unnecessary project lookup, use the configured bridge receipt in tests, and route startup-validation failures through the launcher's error handler.

The replies explain the design choices being retained:

  • Local CLI workspace control is intentional; browser-origin requests now require authentication. Remote callers already require environment credentials.
  • Shared agent replication uses the same ordinary edit authority as the library itself. Requiring an elevated replication role would break normal paired-device edits.
  • The store startup path is synchronous after binding, so the reported callback race has no asynchronous gap.
  • The migration warning came from an incomplete test fixture. The corrected historical snapshot now passes actual contract decoding after migration.

I am not adding docstrings to reach an arbitrary 80% threshold. AGENTS.md asks for comments that explain constraints and decisions, and specifically discourages narrating fields and methods. Useful documentation and focused regression tests are preferable to mechanically documenting every function.

Macroscope skipped correctness review because of the workspace's per-review cost limit; that is not a correctness verdict. This remains a broad integrated feature requiring human review. I have neither changed the workspace's billing settings nor excluded important files to bypass that limit.

Validation on this fix: 586 tests passed across 23 files, scoped typechecks passed, production desktop/server/web/MCP build passed, targeted lint and diff checks passed. Native Windows acceptance and new visual evidence remain the previously disclosed validation gaps. Automated re-review is pending on the new commit.

Implemented and validated with GPT-6 through the Codex harness in T3 Code.

Keep projection failures from blocking provider operations

resolveAgentInstructions calls ProjectionSnapshotQuery.getThreadShellById before reading profileSnapshot, and maps projection failures to ProviderValidationError. The resolver runs in both startSession adapter paths and before sendTurn, so a transient failure can block threads without profile instructions. Treat this optional lookup as best effort or retry it, while preserving failures from required project and instruction-file operations.

Retain the in-memory token when storage access fails.

If setMcpGatewayToken(token) fails, getMcpGatewayToken() can throw from sessionStorage.getItem before setConfigurationError runs. Keep token directly, or guard this fallback read, so denied storage displays the configuration error instead of escaping the blur handler.

cleanup.splice(0) removes every entry before the loop starts. If one close() rejects, the loop stops and the remaining entries are lost. This file registers detached child processes, WebSockets, MCP clients, and temporary directories. A single failure can leave a spawned owner process and an open bridge port behind, which can hang the worker or make later tests fail on the reused port.

♻️ Proposed fix
 afterEach(async () => {
-  for (const close of cleanup.splice(0).toReversed()) await close();
+  const errors: unknown[] = [];
+  for (const close of cleanup.splice(0).toReversed()) {
+    try {
+      await close();
+    } catch (error) {
+      errors.push(error);
+    }
+  }
+  if (errors.length > 0) throw new AggregateError(errors, "Cleanup failed.");
 });

Add an MCP result-size policy before sending tool results. gatewayThreadProjection includes up to 500 messages and allows 120,000 characters per message. Nine maximum-size messages can exceed the 1 MiB ws maxPayload limit before JSON overhead. t3_get_diff also forwards its operation result without a size check. ws closes the session with code 1009 instead of returning a tool error. Reject oversized results with a clear MCP error, or set a limit that covers the largest supported result. t3_get_artifact returns metadata and a URL, not artifact bytes.

- Around line 1920-1925: Update the Effect.catchCause handler around
syncAgentInstructionFile cleanup to re-raise causes that contain only an
interruption, while continuing to log non-interruption failures as warnings.
Preserve interruption propagation so thread.settled does not proceed to
thread.session.stop after the scoped worker is interrupted.

In `@packages/mcp-gateway/src/bridge.test.ts`:
- Around line 838-839: Strengthen the test barrier before the negative
assertion: after the status change, reconfigure oldClient and await its new
configured response so queued status.snapshot delivery has completed, then
assert oldMessages contains no status.snapshot. Update the test flow around
oldClient and the existing negative assertion without changing the production
behavior.

Re-raise interrupt-only causes from instruction cleanup.

The scoped worker can interrupt syncAgentInstructionFile during its filesystem operations. The current Effect.catchCause converts that interruption into a successful warning effect, so thread.settled continues to thread.session.stop. Re-raise interrupt-only causes to preserve this reactor's interruption contract.

Strengthen the barrier before the negative assertion.

The status-change listener queues sendStatusSnapshot in a microtask, but oldMessages updates only when oldClient receives a WebSocket message event. await Promise.resolve() does not wait for that delivery, so the assertion can pass before a wrongly emitted snapshot arrives. Reconfigure oldClient, wait for its new configured response, then assert that no status.snapshot was received.

Keep the preview below composer popovers.

PreviewCardPopup renders its positioner at z-[120]. The embedded ChatComposer renders both the slash-command and stash menus in a body portal at z-40. When their bounds overlap, the preview paints above these menus and blocks pointer selection. Set the preview positioner below the composer layer.

Proposed fix
-          positionerClassName="z-[120]"
+          positionerClassName="z-[30]"

thanks for the substantial work on this. we are closing on product direction and scope. we are not adopting the Agents board and shared-workflow system.

named agent profiles, frozen instructions, chat creation and handoff, previews with replies, PR workflows, and MCP controls introduce a new agent-management product. the separate MCP gateway, credential handling, desktop IPC, and cross-environment runtime machinery add infrastructure commitments alongside it. changes to provider instructions and managed per-thread instruction files also affect agent behavior and project workspaces beyond the UI.

these are product and maintenance commitments we do not want to take on. splitting the patch or cleaning up individual defects would not change that decision.
