- SearchTool now tracked the last emitted line and inserted ellipsis markers when noncontiguous match blocks were output.
- Display output gap markers were padded to align with code-frame gutters.
- Added a regression test that verified a no-context search emits an ellipsis between separated matches in the same file.
- Unified line-ending normalization to `replace(/\r\n?/g, "\\n")` in editor, scraper, benchmark, and utils modules.
- Added terminal-aware line sanitization in code-cell rendering to collapse inline carriage returns and avoid overwrite corruption.
- Tightened editor and paste sanitizers to trim control characters consistently after CR normalization.
- Updated read-line selector parsing to accept line-range selectors ending with a trailing dash.
- Mapped selectors with a trailing dash to open-ended ranges that read from the start line onward without requiring an explicit end.
- Updated read tool documentation to document `:50-` as the shorthand for reading from line 50 onward.
- Updated the hashline prompt to state the tool should never be used for code reformatting tasks.
- Added guidance to run the project's formatter for whitespace, indentation, and style-only edits.
- Replaced per-line carriage-return stripping with CRLF-aware line splitting in hashline input and parser paths.
- Adjusted payload collection to trim trailing whitespace from edit separator lines and handle line matching without extra normalization.
- Removed the now-unused hashline utils module and stopped exporting it from the hashline index barrel.
- Adopted draft-2020-12 tuple validation with `prefixItems`, rejecting array-valued `items`.
- Expanded strict-mode handling to recurse `prefixItems` entries and infer `array` when tuple prefixes exist.
- Normalized Anthropic schemas through `prefixItems`, keeping supported tuple constraints and dropping unsupported fields.
- Updated coding-agent schema metadata and tests to draft-2020-12 `$schema` targets, including MCP/theme fixtures.
- Added `trimTrailingWhitespace()` to strip trailing spaces/tabs and keep the original line when none exist.
- Added homepage metadata entries to the Rust and Python package manifests.
- Replaced OpenRouter HTTP-Referer values with https://omp.sh/ in completion and image requests.
- Updated Codex WebSocket typing and construction to use Bun.WebSocket for handshake header capture.
Fixes#1102
- Updated `raceWithDeadline` to track whether the timeout branch won the race before logging.
- Deferred the startup scan timeout warning until after the race completed with a deferred result.
- Relocated compaction, branch-summarization, pruning, and utils from coding-agent to packages/agent/src/compaction.
- Moved OpenAI remote compaction helpers from packages/ai to the new compaction module.
- Added handoff.ts with extractHandoffDocument, createHandoffContext, and renderHandoffPrompt helpers.
- Exposed new entries.ts with standalone SessionEntry types so coding-agent no longer owns them.
YieldTool's unresolved-ref fallback now skips literal-value positions such as const, enum, default, and examples when looking for unresolved schema refs. Valid schemas containing data literals like { "": "literal" } no longer degrade to the loose schema and still reject invalid yield payloads.
- Runtime-limit timeout is now tracked with a sticky runtimeLimitExceeded flag, so later caller aborts during teardown cannot downgrade the timeout state and let a late yield report success.
- Awaited setup operations before the first prompt are now raced against the subagent abort signal, including auth discovery, model refresh, model resolution, session open, session creation, extension session_start, prompt, and waitForIdle.
- disposeAllKernelSessions removes sessions from the registry before awaiting shutdown, preventing queued work from seeing a registered-but-disposing session and spawning a replacement kernel.
- replaceSessionKernel re-checks registry membership after old-kernel shutdown and after starting a replacement, shutting the replacement down if the session was disposed mid-replace.
- owner-scoped disposal now preserves ownerIds when shutdown is unconfirmed so a later disposeKernelSessionsByOwner(ownerId) can retry.
- Detected async wrapper need via AST traversal instead of regex, enabling pre-demote analysis.
- Published demoted var bindings back to `this` (worker global) when inside the async wrapper, preventing function-scope from hiding them across cells.
- Added `collectBindingNames`/`getLexicalBindingNames` to extract names from destructured patterns.
- Type.String({ format, minLength, maxLength, pattern }) no longer drops the length/pattern constraints when a format selects a Zod format-specific schema (z.email, z.url, z.uuid, …). The instanceof z.ZodString guard never matched those subclasses; constraints are now applied via the shared _ZodString base so all format variants honor them.
- Type.Object without explicit additionalProperties now installs .loose() (matching TypeBox's preserve-extras default) instead of stripping unknown keys. additionalProperties: false continues to install .strict(); a schema value installs .catchall(schemaToZod(schema)).
dereferenceJsonSchema leaves $ref strings in place when references are unresolvable (external URLs, missing definitions, certain cycles). The new yield-parameters builder now walks the resolved schema for any remaining $ref strings before installing validation; if any are found, it throws so the existing catch branch swaps in looseRecordSchema and disables strict validation. Previously YieldTool installed a validator that rejected every success payload with an unresolved-reference error.
The status-line path segment was selecting theme.icon.scratchFolder for scratch directories regardless of opts.stripWorkPrefix, while the CHANGELOG promised both behaviors honor the option. Icon selection now uses the same opts.stripWorkPrefix !== false gate as the scratch path stripping, so disabling stripWorkPrefix keeps the regular folder icon even when the project directory is inside a scratch root.
- Added defensive abort re-check after registering the abortSignal listener plus a checkAbort() immediately before await session.prompt(...), so a wall-clock timer that fires during pre-prompt setup is no longer lost between listener registration and the prompt call.
- Late yield events arriving after a wall-clock timeout no longer flip the result to success: a runtimeLimitExceeded flag derived from the internal abortReason forces wasAborted=true and exitCode=1 regardless of hasYield, while yield payloads remain captured in extractedToolData.
- Async task progress now copies contextTokens and contextWindow from the completed SingleResult onto AgentProgress, so backgrounded tasks still surface their context gauge to the UI.
- executeOnSession's runQueued callback now re-checks sessions.get(sessionId) === session at slot entry and before the dead-kernel replace retry; if the session was removed by disposeAllKernelSessions / disposeKernelSessionsByOwner / resetSession during the queue wait, the queued caller now rejects with PythonExecutionCancelledError instead of spawning an untracked replacement kernel on a stale session object.
- Both dispose paths now inspect KernelShutdownResult.confirmed and retain (or re-insert) sessions whose shutdown was unconfirmed or rejected, logging a warn so a later dispose can retry the kernel instead of orphaning the subprocess.
- buildOpenAiNativeHistory now emits custom_tool_call / custom_tool_call_output for blocks with customWireName (apply_patch and other freeform tools), matching the normal Responses replay path; previously demoted to function_call which broke remote-compaction replay or mismatched the original call.
- requestOpenAiRemoteCompaction and requestRemoteCompaction accept an optional AbortSignal; the coding-agent compaction caller forwards the existing signal so cancellation now terminates the in-flight fetch instead of stranding the session in the compacting state until the server replies.
`SessionManager.close()` queues `#closePersistWriterInternal()` on the
persist chain. The task awaits `#persistWriter.close()`, which flips
`#closing = true` synchronously before yielding on its inner writer
`close()`. A concurrent `appendMessage()` landing in that yield window
hit the hot path, got the still-cached (but closing) writer back from
`#ensurePersistWriter()`, and threw `Error("Writer closed")` from
`writeSync`. The throw was stashed into `#persistError`; the next async
caller (`flush()` or a later `appendMessage()`) re-threw it as an
unhandled rejection with the original line-1282 stack.
Expose `NdjsonFileWriter.isOpen()` and treat a mid-close cached writer
as a miss in `#ensurePersistWriter()`. `_persist` now falls back to the
async `#rewriteFile()` cold path so the entry — already in
`#fileEntries` — still lands on disk once the close drains.
- Added a dedicated `@sinclair/typebox` specifier remap path and routed bare legacy imports to the in-repo shim during extension rewriting and module resolution.
- Added resolve hooks for both `file` and legacy-file namespaces so legacy extensions load the shim consistently at runtime.
- Replaced fromTypeBox conversion with a JSON-schema validator flow in ai tool handling and execution paths.
- Added recursive schema validation and expanded TypeBox checks for refs, enums, uniqueItems, and constraint keywords.
- Sanitized Azure/CCA tool schemas by dropping unsupported fields and rewriting oneOf tool branches as anyOf.
- Tightened argument and model-config validation, preserving unknown tool fields and adding apiKey plus compatibility flags.
- Added canonical `pi.zod` schema API exports and removed TypeBox package exports/imports.
- Migrated Tool schema typing from TypeBox to shared `TSchema`/Zod flow with legacy TypeBox compatibility.
- Updated AI provider adapters and MCP/agent builders to convert tool params through `toolWireSchema()`.
- Reworked schema validation from AJV to Zod-safe parsing with `fromTypeBox`, `toolWireSchema`, and meta schema checks.
- Added a task.maxRuntimeMs setting with a default disabled state for per-subagent runtime limits.
- Updated subprocess execution to enforce the configured wall-clock timeout, mark timeouts as aborts, and include timeout-specific abort messaging.
- Tracked per-turn context size and context window through task progress/results and updated UI renderers to display current context against window with cumulative tokens rendered separately.
- Updated plan-mode and hindsight session state lookups to use Array.findLast for selecting the latest assistant or user message.
- Updated postmortem callback iteration to use Array.toReversed before mapping cleanup callbacks.
- Added OpenAI remote-compaction API support with provider-specific endpoint gating.
- Added buildOpenAiNativeHistory, token-budget estimation, and message trimming for remote-compaction.
- Added helpers to preserve and validate remote-compaction metadata in request/response handling.
- Refactored coding-agent compaction to consume pi-ai remote-compaction helpers with converted message history.
- Exported remote-compaction from ai index and documented the new APIs in CHANGELOG.
- Task tool sessions now expose and forward parent OpenTelemetry config when creating subagent tasks.
- Subprocess execution now derives child telemetry from the parent config with the subagent identity and child session conversation handling.
- Subagent creation now records a handoff span using the resolved parent telemetry handle before running the child loop.
- Adjusted OutputSink to disable head retention after replace(), resetting counters so later pushes append to the tail and do not trigger stale middle-elision in dump().
- Refined artifact link emission to insert a newline separator only when the minimized output lacked one.
- Added a regression test for replace-plus-push ordering that verifies no elision marker and aligned byte counts.
- Added opt-in telemetry configuration to Agent and session APIs, including Agent#setTelemetry mutator.
- Implemented OpenTelemetry spans for invoke_agent, chat, execute_tool, and handoff paths with metadata and step tracking.
- Added a telemetry helper module, OpenTelemetry request/usage types, and dependency wiring with no-op behavior when tracer SDK is absent.
- Added OTEL end-to-end tests and fixed coding-agent OutputSink realignment and artifact-link newline output issues.
When initialServiceTier is resolved from settings (e.g. the user has
serviceTier: priority configured as a default), sdk.ts wrote model_change
and thinking_level_change entries for the new session but omitted
service_tier_change. The stats parser derives priority-tier premium counts
from service_tier_change entries, so sessions started in fast mode without
an explicit /fast toggle had no tier entry and were undercounted in omp-stats.
Mirror the thinking_level_change pattern: write service_tier_change
alongside the other initial entries when initialServiceTier is set.
isUrlLikeSpecifier matched Windows absolute paths (e.g. `C:\foo`) because the URL-scheme regex `^[A-Za-z][A-Za-z\d+.-]*:` happily eats a single drive letter. When a legacy plugin extension imported a bare-specifier dep from its own `node_modules`, rewriteBareImportsForLegacyExtension resolved it to an absolute path, then toRewrittenImportSpecifier short-circuited pathToFileURL and embedded the raw Windows path into the mirrored TS source.
The TS string-literal parser then ate \n, \U, \y and friends, producing nonsense package specifiers like `C:Usersjames.ompagentextensionssupipowers\node_modulesyamldistindex.js` that Bun rejected with `Cannot find package …`. Net effect: every legacy extension that pulls in any node_modules dep failed to load on Windows.
Fix: reject `^[A-Za-z]:[\\/]` in isUrlLikeSpecifier before the URL-scheme test so drive-letter paths flow through pathToFileURL and reach the mirror as proper `file:///C:/...` URLs.
- Added a shared session command helper that aggregates extension, prompt, and skill slash commands.
- Updated ACP, extension UI, runtime-init, and task executor extension contexts to return session command data instead of empty arrays.
- Updated root marker detection to read the directory once and match glob markers against top-level entries, preventing recursive scans when checking project roots.
- Adjusted root-marker glob error handling to warn on directory listing failures and treat the marker set as absent when unreadable.
- Reduced marksman's configured warmup timeout from 15,000 ms to 2,000 ms in LSP defaults.
- Updated collectPayload to accept intervening blank lines as empty payload when requirePayload is true and no payload has been collected yet.
- Added a fallback path alongside the HL_EDIT_SEP check so blank insertions without a separator are tolerated as required-payload op payload lines.
- Updated hashline splitting to skip emitting a section when a path header has no following operations.
- Added a trimmed non-empty check so only sections with diff content are returned.
- Added tests for duplicate and trailing headers to ensure empty header-only chunks are silently dropped.
- Added a `resolveSearchRepoScope` helper that uses an explicit `repo` when provided, skips defaulting when a query already contains a repo/org/user/owner scope qualifier, and otherwise resolves the current checkout via `resolveDefaultRepoMemoized`.
- Updated `search_issues`, `search_prs`, `search_code`, and `search_commits` to use the resolver before composing API queries, defaulting `repo` when omitted but silently falling back to an unscoped search on resolution failure.
- Documented the new search-repo defaulting rules in tool prompts, user docs, and the package changelog.
The agentic commit pipeline (`omp commit`) wrote its commit and then sat
spinning on Ctrl+C because nothing in `Commit.run()` drained the lingering
event-loop handles: `installH2Fetch()` keeps idle HTTP/2 sockets warm to
the provider, the Settings autosave timer can still be armed, and the
AgentSession's extension/runner machinery holds onto async-job and OAuth
refresh state even after `session.dispose()` releases what it knows how
to. Mirror the `runPrintMode` exit path from `main.ts` by calling
`postmortem.quit(0)` once `runCommitCommand` resolves so the CLI returns
to the shell, runs registered cleanup callbacks, then exits — same model
the non-interactive launch flow already uses.
Also widens the private bash-tool helpers' `notices` parameter to
`readonly string[]` so `bun check:types` keeps passing — the public outer
arm already accepted `readonly string[]` and an upstream commit had only
partially propagated the change.
