- 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.

- 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.
- Added a new `--advisor` flag to argument parsing and launch flag definitions.
- Applied the parsed `advisor` flag as a runtime-only override of `advisor.enabled` during startup.
- Updated advisor-related docs and added parseArgs tests for `--advisor` behavior and position handling.
- Fixed cold revival flow so parked subagents are restored from persisted sessions at startup.
- Fixed session-init persistence to include spawns and readSummarize fields for replay accuracy.
- Fixed latest-session lookup by adding peekSessionInit for lock-free persisted contract access.
- Added lifecycle and session tests for cold-revive success, decline, and retry paths.
- Passed USER_INTERRUPT_LABEL through abort paths in collab, ACP, RPC, runtime, and SDK flows.
- Added userInitiated to synthetic continue inputs and session prompt calls.
- Suppressed advisor auto-resume during user aborts and preserved queued concerns.
- Cleared suppression on user prompts and reclaimed parked advisor cards on abort settle.
- Added discovery of local, user, and ancestor `WATCHDOG.md` files via `discoverWatchdogFiles`.
- Appended discovered watchdog prompts to advisor system prompts during session setup.
- Added protocol startup defaults that force `advisor.enabled` and `advisor.subagents` false.
- Handled `maintainContext` failures and drained pending updates before token estimation.
- Added a streamingBehavior field to submitted user inputs and threaded it through interactive mode types and controller start-up.
- Updated interactive submission dispatch to default to followUp queueing while preserving explicit steer intent when provided.
- Changed tests to verify followUp and steer queueing behavior, preventing AgentBusyError from race-window busy sessions.
Recorded durable tool-start and session-exit markers so resumes can warn when a prior branch ended with pending tool calls.
Added regression coverage for pending bash tool calls and shutdown diagnostics.
Fixes#2606
- Added session-domain modules and exports for session-entries, context, listing, loader, and migrations.
- Changed persistence to async append writes plus writeTextAtomic, removing sync line APIs.
- Added compaction-aware session context rebuild with dangling tool-call cleanup.
- Added resumable session resolution with status inference, id/stem/suffix matching, and backup recovery.
Plan approval dispatched the executor's first synthetic prompt without
checking whether the agent was still streaming the post-resolve
continuation (or a turn started by the approve-time compaction/clear),
surfacing "Failed to finalize approved plan: ... Agent is already
processing". Loop auto-submit and goal continuations hit the same throw
via submitInteractiveInput, which always called prompt/promptCustomMessage
without a streamingBehavior.
#approvePlan now aborts any in-flight turn before the synthetic prompt,
and submitInteractiveInput routes submissions through the steer/follow-up
queue (streamingBehavior: "followUp") when the session is streaming.
Non-streaming call shapes are unchanged. Extends the manual-/goal fix
(#2454) to the continuation and plan-approval paths.
Bare `omp --list-models` (or any other stale/typoed --flag) was silently
consumed by `parseArgs` and the agent went on to start a real session,
connect to the configured MCP servers, and hang waiting on the model.
Any positional after the unknown flag was reinterpreted as the initial
prompt, so a documentation drift turned into an unintended LLM invocation.
`parseArgs` now tracks flag-shaped tokens that did not match any built-in
or extension-registered flag in a new `unrecognizedFlags: string[]` field,
and `reportUnrecognizedFlags` prints a clean `Error: unknown flag(s): …`
line plus the `--help` hint. `runRootCommand` invokes the helper right
after the post-extension reparse and `process.exit(2)`s before any
session, MCP, or initial-message work runs.
The validation is gated on the extension-aware reparse, so extension
flags (`--spawn-peer`, `--headless`, `--plan`, …) still pass through
the same way `applyExtensionFlags` already handles them. `-` (stdin
marker) and `--` (POSIX separator) are deliberately allowed through.
Fixes#2459
- Added `omp models` command with `ls`, `find`, `canonical`, and `refresh` actions.
- Removed top-level `--list-models` parsing from CLI args, launch, and main command flow.
- Implemented action-driven model listing with provider filtering, extension loading, and `--json` output.
- Updated unknown provider/model errors and tests to direct users to `omp models` guidance.
- Extended `parseCollabLink` test coverage to reject 16-byte and 40-byte fragments instead of only rejecting short keys.
- Added coverage for full-link fragments to ensure key and write token are parsed when present.
- Updated `GuestClient` test setup so `welcomeFrame` carries a `readOnly` flag into snapshot assertions.
Gated the Model scope banner suffix on the original scope's explicitThinkingLevel flag and switched the display source back to the pre-default ScopedModel[] so non-explicit scope entries no longer render the global default thinking level.
Fixes#2385
Respect startup.quiet when building the interactive model-scope notification so quiet launches do not emit startup chrome for large enabledModels scopes.\n\nFixes #2386
Fixed the interactive Model scope formatter so unset thinking levels omit the suffix and explicit levels render as id:level.
Added regression coverage for the startup banner list formatter.
