The prior flow delayed the initial title until the first turn finished, which meant the sidebar showed "New conversation" for the entire turn. Now emit the truncated user-question title as soon as the turn starts, and upgrade to the AI-generated title at the end only when it differs. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Add capabilitySummary and capabilityExample fields to DirectConnector and populate them across all 17 built-in connectors. These feed the harness-side capability block so codex sees ground truth about which services are live instead of relying on its training priors.

…ilter Teach the codex app-server harness about the connectors and external MCP servers live in the current Anton session so the model answers "do you have access to X?" from ground truth instead of training priors. - Expose Anton's ConnectorManager AND McpManager tools to harness sessions via AntonToolRegistry. Previously external MCP tools never reached harness CLIs, even when the server was connected. - Bake an "Active Anton Connectors" block into developerInstructions once at thread/start under the `anton:` MCP namespace. Immutable for the thread, so no per-turn token cost. - Add an optional `surfaces?: string[]` allowlist to McpServerConfig so developer-machine MCP servers don't leak their tools into Slack / Telegram sessions. Undefined = all surfaces (default). - Log tools/list responses served over the harness IPC bridge and log the capability block install after thread/start resolves.

- Add HarnessSetupModal for CLI install/login flow per provider - Add local-only accountStore (display name + avatar color, localStorage) - Wire Sidebar avatar/name to accountStore, open Settings on click - Route ModelSelector "manage" to Settings > models via custom event - Portal popovers/previews (project menu, image hover) to document.body - Randomized greeting tail on home screen - Routines "New" opens a draft conversation instead of inline create - Settings modal redesign and expanded index.css styles Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Summary
Three related fixes to the harness / session stack:
thread/start.developerInstructionsonce per codex session so the model answers "do you have access to X?" from ground truth (live connectors + enabled MCP servers) instead of training priors. Immutable for the thread → no per-turn token cost.McpManagerintoAntonToolRegistryso external MCP server tools reach harness CLIs. Previously harness sessions received zero tools from user-added MCP connectors even when they were connected.Supporting changes:
capabilitySummary+capabilityExample(17 built-in connectors updated).surfaces?: string[]onMcpServerConfig(default = all surfaces) so dev-machine MCP servers don't leak into Slack / Telegram sessions. Filter applied in bothMcpManager.getAllTools(surface)andcollectLiveConnectorsForPrompt.tools/list served to harnesson every IPC response; log capability-block install afterthread/startresolves.Commits
