Review follow-up: a live subagent focused from the Agent Hub renders its
session name in the status line (session_name segment reads
sessionManager.getSessionName()), so the blanket agentKind === "sub" skip
made the user-enabled title.refreshOnReplan silently ineffective and left
focused subagents untitled after their first todo replan.
Focus only exists in an interactive host, and subagents run in-process, so
gate the skip on a process-global interactive-host flag: subagents skip the
replan title refresh only in non-interactive hosts (print/RPC/ACP/eval/SDK/
CI) where no session tree is focusable. The interactive entrypoint declares
the host via setInteractiveHost(isInteractive); the flag defaults false, so
bun test and headless embedders keep the optimization without leaking state.
Fixes#5910
Claimed Bun's singleton stdin reader before loading extensions and passed the owned stream into RPC and RPC-UI mode.
Added process-level regressions for both modes with a startup extension that attempts to lock stdin.
Fixes#5898
- Added schema and type updates for task-agent fields and model resolver settings.
- Extended discovery helper logic to carry resolved task-agent metadata through execution setup.
- Updated task/agent registration and execution paths to use the new capability/field data.
- Expanded test coverage for agent-field parsing, model resolution, and executor prewalk behavior.
Extended the OTLP export bootstrap beyond traces so omp emits the full
OpenTelemetry signal set from a single session.
- Registered a LoggerProvider + BatchLogRecordProcessor and a MeterProvider
+ PeriodicExportingMetricReader when their OTLP endpoints (or the shared
endpoint) are set, each gated independently by OTEL_*_EXPORTER=none,
OTEL_SDK_DISABLED, and http/protobuf protocol checks.
- Bridged the centralized logger through a new registerLogSink API so every
log event also becomes an OTLP log record with severity, attributes, and
active span context for log-trace correlation (min level via OTEL_LOG_LEVEL).
- Recorded gen_ai.client.token.usage and pi.omp.agent.* metrics from the
agent run summary and per-chat usage hooks, and emitted a structured run
summary log event.
- Added an out-of-process logs+metrics probe and gating tests covering the
per-signal kill switches.
Fixes#4604
- Replaced legacy `pi/` role alias prefix with canonical `@` syntax across model resolution, documentation, and tests.
- Added support for bare `*` default alias and multiple alias prefix detection with custom role resolution in `resolveConfiguredRolePattern()`.
- Enhanced thinking suffix parsing to accept unambiguous abbreviations (minimum 2 characters) for effort and level selectors.
- Extended `resolveCliModel()` and `filterAvailableModelsByEnabledPatterns()` to accept settings parameter for role alias resolution from `--model` flag.
- Removed the `downshift.boomerang` feature, including CLI flags, configuration schema settings, and internal session state logic.
- Deleted the associated prompt definition file and all unit tests related to the boomerang validation flow.
- Cleaned up frontend forms and server request handling in the harbor-manager package to reflect the feature removal.
- Updated the downshift planning prompt instructions to maintain continuity in task creation.
- Introduced `--downshift-boomerang` CLI flag and `downshift.boomerang` configuration setting.
- Integrated boomerang validation hand-back logic and context cutting within the agent session.
- Added system prompt templates and runtime checks to facilitate message handling for boomerang transitions.
- Included unit tests to verify context management and validation pass requirements during the boomerang process.
- Replaced legacy reasoning-slide functionality with new downshift and plan-yolo capabilities.
- Updated CLI arguments, slash commands, and configuration schemas to support the new model-switching and execution behaviors.
- Refactored agent session logic to handle downshift arming, plan-yolo headless execution, and context scrubbing.
- Renamed and added system prompts to align with the updated downshift and plan-yolo workflows.
- Introduced a project-scoped `launch` tool to orchestrate long-running services, debuggers, and watchers with persistent execution capabilities.
- Implemented a robust daemon broker with Unix/Windows IPC transport that manages process lifecycles, readiness monitoring, and automatic log rotation.
- Added detached process support to ensure services persist independently of the main application lifecycle, including recovery and cleanup mechanisms.
- Updated the `bash` interceptor to prioritize the new `launch` tool for background processes and provided comprehensive documentation for lifecycle and signal handling.
Reuse raw argv during the extension-aware parse so explicit session ids are removed without dropping a following user prompt.

Identify explicit session ids from the token immediately following --continue so extension-owned values remain untouched while session resolution targets the requested id.

Skipped UUID-shaped positional normalization while startup parsing still contains unrecognized extension flags, then normalized the extension-aware parse.
Signed-off-by: Christian Stewart <christian@aperture.us>
Normalized UUID-shaped --continue targets on the extension-aware argument parse so the session id cannot leak back into the initial prompt.
Signed-off-by: Christian Stewart <christian@aperture.us>
Treated a UUID passed after --continue as an explicit session target so a missing id cannot fall back to the latest persisted session.

- 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
- Treated startup scoped model selection as a prompt-cache shape override before inheriting fork cache keys.
- Covered the --models fork path so a scoped startup model cannot reuse the parent prompt_cache_key.
Fixes#5035
- 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
Converted ArkType validation failures into ConfigError results and surfaced models.yml validation failures in CLI model listing and noninteractive startup.
Fixes#4305
buildSessionOptions in packages/coding-agent/src/main.ts awaited three independent resolvePromptInput calls for SYSTEM.md, APPEND_SYSTEM.md, and TITLE_SYSTEM.md sequentially, adding unnecessary I/O latency on the startup path. Replace the sequential awaits with Promise.all so the three file reads run concurrently while preserving the same variable assignments and error propagation. Verified with bun run check:types and the coding-agent-heavy test suite.
Closes#4247
- Consolidated duplicated inline thinking level comparisons into a unified `concreteThinkingLevel` helper.
- Enhanced legacy tool shims to respect isolated session settings and support legacy options.
- Cleaned up redundant UI render requests and extra status-line updates.
- Refactored `grep` tool shim to configure context dynamically via isolated settings.
- Disabled platform-incompatible shell shim tests on Windows environments.
- Removed the canonical model variant indexing, selection, and tracking logic from the model registry and resolver.
- Eliminated the `canonical` sub-command, tab view, search tokens, and equivalence configuration structures from the CLI and model selector components.
- Refined model identification, lookup, and provider fallback resolution to bind exclusively to standard, raw model IDs.
- Relocated the equivalence utility script within the catalog package to support script-only policy generation.
- Migrated global service tier settings to a per-model-family architecture (OpenAI, Anthropic, Google).

- Added automatic migration logic for legacy service tier and fast-mode application settings.
- Updated telemetry, session management, and task execution to support provider-specific tier resolution.
createAcpSessionFactory spreads baseOptions into every per-session
createAgentSession call. baseOptions.titleSystemPrompt was resolved
once at launch from main.ts, so opening session/new for a client-
supplied workspace different from the launch cwd would carry the
launch repo's TITLE_SYSTEM.md into the new session and bias replan
title refreshes against the wrong policy.
The factory now calls discoverTitleSystemPromptFile(cwd) +
resolvePromptInput per session and passes the result after the spread,
overriding the launch-time value. When the target workspace has no
override, undefined wins and the bundled prompt is used as expected.
Regression test asserts that a per-session cwd with a project-level
TITLE_SYSTEM.md beats the launch-cwd prompt threaded through
baseOptions.
The replan-driven title refresh (title.refreshOnReplan, fired after a
`todo init`) called `generateSessionTitle()` without the user's
`TITLE_SYSTEM.md` override, silently falling back to the bundled
`prompts/system/title-system.md` and overwriting auto titles with the
default policy. The override was only ever discovered by main.ts and
passed into the first-input title path on InteractiveMode, never into
`AgentSession.#refreshTitleAfterReplan`. Most visible in Plan Mode,
which initializes todos early.
`AgentSession` now owns the resolved title prompt:
- New `CreateAgentSessionOptions.titleSystemPrompt` threaded by
`createAgentSession()` into the constructor.
- New `AgentSessionConfig.titleSystemPrompt` stored on
`#titleSystemPrompt` with a `get titleSystemPrompt` /
`setTitleSystemPrompt(...)` pair.
- `#refreshTitleAfterReplan` passes `#titleSystemPrompt` as
`customSystemPrompt` to `generateSessionTitle()`.
- `input-controller.ts` reads from `session.titleSystemPrompt`, and
the duplicate `InteractiveMode.titleSystemPrompt` field /
constructor arg / `InteractiveModeContext` field / `runInteractiveMode`
parameter are removed. `InteractiveMode.refreshTitleSystemPrompt`
now calls `session.setTitleSystemPrompt(...)` so a `/move`-style cwd
change keeps the override in sync.
Regression test asserts the prompt handed to `completeSimple()` from
`#refreshTitleAfterReplan` is the configured override, not the bundled
`title-system.md`.
Fixes#3734
- Introduced `serviceTierSubagent` and `serviceTierAdvisor` settings to allow independent service tier control for subagents and the advisor model.
- Enabled `"inherit"` mode for these settings, allowing subagents and the advisor to track the main session's live effective service tier, including dynamic toggles like `/fast`.
- Added a resolution layer to ensure service tier propagation from parent sessions to spawned task agents and evaluators.
- Force process exit when the startup session picker is cancelled instead of returning.
- Prevent hanging the event loop caused by long-lived startup handles such as theme listeners and timers.
- Add regression test case to verify clean process termination upon picker cancellation.
Re-added the isConfigured guard inside applyDefaultSettingOverrides so the
runtime override applied at RPC/ACP startup only fills holes — explicit
embedder/project/--config/global values now survive for task.isolation.{mode,
merge,commits}, task.{eager,batch,maxConcurrency,maxRecursionDepth,disabledAgents,
agentModelOverrides}, memory.backend, memories.enabled, advisor.{enabled,
subagents,syncBacklog,immuneTurns}, plus the RPC-only async.{enabled,maxJobs}
and bash.autoBackground.{enabled,thresholdMs}. The guard was originally added
for #2598 and had quietly regressed, so the override re-asserted the schema
default and clobbered every explicit value — matching the contract problem
#2828 already fixed for the todo paths.
Replaced the prior 'default-disables advisor' test (which codified the
clobbering as the contract) with a comprehensive 'honors explicit
host-defaulted settings' regression covering every contested path across
rpc/rpc-ui/acp.
Fixes#3207
- Added `omitThinking` setting to allow instruction of upstream providers to omit thinking summaries.
- Decoupled UI-level thinking block visibility from backend data retrieval.
- Updated session creation to use `omitThinking` for configuring provider-side summaries.
The session picker auto-switched into all-projects scope whenever the
current cwd had no sessions, so /resume from a fresh project silently
surfaced every other project's history. The empty-folder hint already
tells users to Tab into all-projects, but the auto-switch made it
unreachable. Both call sites (the /resume slash command and `omp
--resume` startup) now always open in folder scope; `omp --resume`
keeps the global probe only to early-exit with 'No sessions found' when
nothing exists anywhere. The component-level `startInAllScope` option
is deleted along with its callers.
Fixes#3099
- Export `directoryExists` in `utils` to safely validate working directories before traversal.
- Update `SessionManager` and startup logic to fallback to the launch directory if a session's recorded working directory no longer exists.
- Add regression tests to ensure sessions now correctly adopt the launch directory instead of crashing on missing paths.
- Included advisor syncBacklog and immuneTurns in the default-resetting configuration for protocol hosts.
- Updated the lazy startup tests to verify that these settings are reset to defaults rather than inheriting user-defined values when a protocol host initiates.
Threading printThoughts only into runPrintMode is too late when
hideThinkingBlock is set (settings or --hide-thinking): the session is
built with hideThinkingSummary=true, so the provider omits reasoning
summaries and --print-thoughts prints nothing. Override hideThinkingBlock
to false for single-shot print mode before session creation, gated on
print mode; an explicit --hide-thinking still wins.
