- Transitioned vibe tools to an ephemeral registration model where they are installed only when entering `/vibe` mode and removed upon exit.
- 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.
- 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.
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
- 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.
- Centralized task concurrency and delegation logic by moving instructions from individual tool descriptions to the system prompt.
- Introduced conditional system prompt logic to handle model-specific task policies, including support for GPT-5.6.
- Added infrastructure for task concurrency normalization and IRC steering state within the system prompt configuration.
- Refactored prompt inputs and session logic to enable dynamic system prompt updates based on model-specific policy cohorts.
- Introduced `Max` as a first-class reasoning effort tier across all packages, including AI providers, coding agent configurations, and RPC protocols.
- Refactored model effort ladders to use wire-exact mappings and removed legacy effort aliasing (e.g., `max-to-xhigh` mapping).
- Updated model registry and provider configurations to support `Max` tier routing, color themes, and UI icon associations.
- Expanded test suites to provide end-to-end coverage for the new reasoning tier, including updated compatibility and fallback scenarios.
Separated advisor provider session identity from local advisor labels so Codex requests carry stable UUIDv7 values while transcripts keep their advisor-specific names.
Fixes#5040
- Persisted an inherited provider prompt-cache key on full session forks while keeping the child OMP session id independent.
- Added --prompt-cache-key and SDK startup inheritance so explicit cache affinity is separate from provider session routing.
- Cleared automatic inherited keys when model, thinking, system prompt, or tool schema inputs change.
Fixes#5035
- Marked terminal yield state in the synchronous tool-result hook before aborting the loop.
- Ignored the later tool_execution_end event for synchronously terminated yield calls so stale events cannot suppress the next prompt.
Fixes#4963
Interactive sessions defer MCP discovery, so CLI --tools produced an initial built-in-only active set and later MCP refreshes respected that filtered set.
Force-activate deferred MCP tools when MCP discovery mode is disabled, matching the blocking startup path while leaving discovery-mode selection intact.
Fixes#5013
Avoided reattaching snapcompact archive image blocks when rebuilding collapsed transcript contexts so live TUI resumes do not retain archived frames.
Added regression coverage for collapsed transcripts while preserving full transcript and provider context frame reattachment.
Fixes#4979
- Aborted the active agent loop synchronously when a terminal yield tool result finishes, so IRC-wake turns stop before another provider call.
- Added a regression covering idle IRC wake handling after a terminal yield.
Fixes#4963
Extensions calling ctx.ui.addAutocompleteProvider (e.g. @ff-labs/pi-fff)
crashed at load with 'TypeError: ... is not a function' because omp's
ExtensionAPI.ui omitted pi's autocomplete-provider API; the throw also
aborted the rest of a try/catch-guarded session_start init.
ExtensionUIContext now declares addAutocompleteProvider(factory).
Interactive mode stacks each factory on the built-in editor provider in
registration order, re-applies the stack on every slash-command refresh,
and skips throwing/malformed factories; RPC, ACP, and headless contexts
accept the factory as a no-op, matching upstream pi's RPC behavior.
Fixes#4919
Extension sendUserMessage() without deliverAs fell through to prompt(),
which throws AgentBusyError during an active stream; the message was
dropped and surfaced as 'Extension sendUserMessage failed'. Route the
omitted-deliverAs path through prompt() with streamingBehavior 'steer'
so streaming queues a steer with normal prompt-flow side effects
(keyword notices, advisor auto-resume reset) and idle still starts a
turn.
ACP skill-command prompts now pass streamingBehavior 'steer'; the RPC
skill fast-path honors the prompt command's streamingBehavior field
(default steer) like the plain-prompt path already did. Documented the
extension-facing delivery semantics.
Synthesized from PR #4942 (prompt-flow steer routing, docs, tests) and
PR #4922 (RPC streamingBehavior threading, steer regression test);
dropped PR #4942's unrelated workflow-notice.md ellipsis churn.
Fixes#4923

- Added `onTurnError` hook to `AdvisorRuntime` to handle failed turns before retries.
- Integrated credential blocking in `AgentSession` to prevent retrying usage-limited accounts when advisor turns fail.
- Included account key in `codex-auto-reset` debug logs to improve skip reason visibility.
Drained pending IRC asides before parking irc wait so replies that arrive between wait calls are returned instead of being treated only as queued interrupts.
Added regression coverage for the already-aborted queued-IRC signal path and documented the fix in the coding-agent changelog.
Fixes#4657
Reset per-turn maintenance counters before IRC wake prompts so yielded subagents do not carry stale yield termination into later wake turns.
Add regression coverage for empty-stop retry after an IRC wake following a yielded run.
Fixes#4658
- Allowed implicit default fallback resolution when other role fallback chains are configured.
- Covered the mixed-role first-run fallback case.
Fixes#4533
