- Added `activateVibeTools` and `deactivateVibeTools` methods to `AgentSession` to manage these transient tool registrations.
- Removed vibe tools from the default global tool registry, preventing unnecessary background exposure.
- Implement a zero-match watchdog for browser selector operations that aborts after ~2s if no elements are found, preventing actions from unnecessarily consuming the full deadline.

- Update `waitFor` and `waitForSelector` to conditionally opt out of the fast-fail mechanism when explicit timeouts or hidden-state expectations are provided.

- Added comprehensive unit tests for Vibe tool renderers and updated runtime registry logic to support rich screen snapshots.
- Implemented Vibe mode to enable worker session management and director-role context injection.
- Added a `/vibe` slash command and integrated status line UI to display mode activity.
- Configured restricted toolsets and guards to prevent concurrent conflicts with existing Goal or Plan modes.
- Provided system prompts and tool templates to support specialized agent communication and task orchestration.
- Added a fallback to emit error messages during `agent_end` if no error was previously streamed during the turn.

- Forced tab activation before screenshot capture to prevent stale or sibling-tab image data in shared-endpoint environments.
- Disable context expansion in raw mode to ensure verbatim content extraction.
- Enforce strict adherence to requested line ranges when raw selectors are used.
- Remove padding in range calculations to prevent indistinguishable context lines in raw output.
- Removed the `plan` agent definition and associated prompt file from bundled agents.
- Updated documentation to reflect the removal of `plan` from available subagents.
- Cleaned up related tests to remove references to the deprecated agent.
- Clarified that the agent must handle top-level scoping, planning, and cross-slice contracts before delegating work.
- Restricted subagent usage to scenarios with genuine parallelism, discouraging "spawn-one-then-wait" patterns.
- Updated criteria for inline work to include cases with only a single runnable slice, preventing unnecessary handoffs.
- Preserved newest-first ordering for startup changelog markdown so collapsed notices report the current release.
- Kept default changelog rendering oldest-first for explicit recent/full views.
- Added regression assertions for both startup and full-history heading order.
- Treated missing or invalid changelog markers as first install and persisted the current version without replaying historical notes.
- Shared bounded changelog rendering between startup and recent changelog views, with a 64 KiB startup cap and full-history hint on truncation.
- Added marker, truncation, recent/full rendering, and PTY startup regression coverage.
Fixes#5135
- Ran commit host completion before commit-agent session disposal so mnemopi/autolearn teardown cannot preempt a valid proposal.
- Converted missing commit-agent host outputs and split-plan gaps into thrown errors so omp commit cannot resolve into exit 0 without creating a commit.
- Preserved caller GPG_TTY state instead of forcing a bogus signing TTY in git and non-interactive subprocess environments.
Fixes#4794
Emitted a failed auto-retry event when empty assistant stop responses exhaust their retry cap so the TUI can show an error instead of silently settling.
Fixes#5128
- Applied the known reasoning envelope filter when deciding whether a title marker is visible.
- Added title extraction regressions for reasoning tag and reasoning fence envelopes before the visible title.
Fixes#5122
- Limited markerless fallback cleanup to leading leaked-thinking envelopes so literal reasoning syntax in plain titles survives.
- Added markerless regression coverage for think tags and thinking-fence titles.
Fixes#5122
- Parse only title markers that remain visible after leaked-thinking cleanup so markers inside leaked reasoning are skipped.
- Preserve literal reasoning tag syntax inside the chosen title and cover it with a regression test.
Fixes#5122
- Reused the leaked-thinking healer before parsing title markers so visible reasoning envelopes cannot win extraction.
- Added regression coverage for <thinking> and <think> envelopes that contain internal title tags before the real title.
Fixes#5122
- Introduced `stringifyJson` helper to preserve bigint precision by serializing them as decimal strings.
- Replaced native `JSON.stringify` across compaction and session management modules to prevent serialization errors when handling bigint values in tool arguments.
- Added regression tests in `agent` and `coding-agent` packages to ensure bigint tool arguments remain intact through compaction and persistence flows.

Fixes#5081
- Added durable SQLite refresh ownership for stored OAuth rows, with canonical re-read before refresh and compare-and-set persistence.
- Routed MCP proactive and forced OAuth refresh through the shared owner so waiters reuse the winner's rotated credential.
- Added MCP regression tests for shared SQLite refresh ownership and stale invalid_grant losers.
Fixes#5081
- Instruct the advisor to stop policing scope, ambition, or backwards compatibility unless explicitly requested by the user.
- Adjust the blocker criteria to require explicit contradictions of user instructions rather than subjective assessments of refactor size or scope.
Clerk and similar providers bind DCR clients to only the scopes declared at
registration. Authorize then requests scopes_supported (including openid),
which rejects with "client is not allowed to request scope 'openid'". Match
Claude Code by sending config.scopes as RFC 7591 scope on the DCR body.
Switched stdio MCP server launches to the argv-first Bun.spawn overload used by JS eval so macOS TCC Apple Events prompts reach children like xcrun mcpbridge.
Added regression coverage for the spawn call shape.
Fixes#5085
Rendered the /move directory picker using the overlay layout width instead of the legacy fixed 68-column frame.
Added regression coverage for non-68-column overlay frames.
Fixes#5067
