- Canonicalized assistant and thinking messages by trimming and collapsing dot text.
- Skipped rendering assistant and thinking blocks when canonicalized content was empty.
- Filtered ACP thinking notifications and session outputs to ignore placeholder content.
- Added canonicalizeMessage tests for undefined, blank, whitespace, and dot-only inputs.
- Updated compaction, branch summarization, and session dump formatting to pass preferred model tool syntax into conversation serialization.
- Enhanced shared serializers to render assistant tool calls and tool results through grammar envelopes when syntax is available, with the prior compact format as fallback.
- Aligned prompt, preview, and test fixtures to the new transcript tags: `[Think]`, `[Tool Call]`, and `[Tool Result]`.
- Added `WorkerInbox` and `installWorkerInbox(port)` to queue worker messages before bind.
- Added `consumeWorkerInbox()` to replay buffered messages and clear one active inbox.
- Added buffered inbox consumption in JS and tab worker transports before direct message handlers.
- Normalized worker selector arguments to the `__omp_worker_*` naming across workers and tests.
- Added an `interruptible` field to AgentTool and documented when it is honored.
- Updated immediate-mode tool execution to poll steering during in-flight interruptible calls and abort them when steering is queued.
- Marked the coding `job` tool as interruptible and added tests covering mid-wait aborts versus boundary-only steering drain.
- Replaced Bun.sleep and wall-clock timing with fake timers (vi.useFakeTimers), release gates, and deterministic polling across 15+ test files to eliminate flakiness and improve speed.
- Consolidated per-test fixture setup into beforeAll/afterAll lifecycle hooks across 20+ test files, reducing redundant initialization and improving test performance by reusing shared immutable fixtures.
- Stubbed network calls in ModelRegistry and test discovery to prevent unintended outbound requests during test execution.
- Replaced subprocess-based test coordination (file markers, Bun.sleep polling) with in-memory fakes (FakeWebSocket, FakeLspServer, VirtualClock) for deterministic, fast test execution.
- Added Gemini and Gemma syntax routing by model family and owned syntax env values.
- Added Gemini and Gemma in-band parsers for tool_code and token-based tool_call streams.
- Added rendering support for Gemini fenced tool_code/tool_outputs and Gemma tool tokens.
- Fixed parsing edge cases for comments, string escapes, nested args, and truncated blocks.
- 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.
- Captured each row's initial position in AgentHubOverlayComponent on first refresh and reused it on later refreshes.
- Changed subsequent sorting to prioritize status then prior row position, so activity updates no longer reordered visible rows.
- Added a regression test that verifies row ordering stays stable when activity changes and new agents append at the end.
- #handleAgentEvent now delegates non-`agent_end` events to a new `#processAgentEvent` routine.
- For `agent_end`, it tracked a resolver promise via `#trackPostPromptTask` before awaiting event handling and resolved it in `finally`.
- This kept `#waitForPostPromptRecovery()` from returning before deferred compaction or handoff work was registered.
Track the non-message token estimate used for provider-anchored assistant usage, then add only positive current system/tool growth during pre-prompt threshold checks. Restore released collab changelog entries to the immutable 15.13.1 section.
Fixes#2628
Include the current system prompt and active tool schemas when provider-anchored pre-prompt checks estimate threshold pressure, and cover the case with a regression test.
Fixes#2628
Use provider-anchored context usage for pre-prompt context-full threshold checks when available, then add only pending prompt tokens. This keeps OpenAI Responses encrypted reasoning payloads from overcounting local prompt pressure while the visible context usage remains below threshold.
Fixes#2628
- Added `features.unexpectedStopDetection` and `unexpectedStopModel` settings for opt-in behavior.
- Added assistant-stop handling to classify stop reasons and resume generation with retry prompts.
- Added unexpected-stop classifier logic with candidate checks, model fallback, and YES/NO parsing.
- Added retry tracking that caps auto-continues at three attempts and logs a warning when exceeded.
- Updated worker core so it emitted `ready` only after receiving an `init` message instead of on construction.
- Changed worker startup to send `init` before waiting for readiness, enabling startup errors to fail fast and trigger fallback.
- Expanded JS worker tests with startup-error simulation and verified execution falls back to the inline worker when spawning fails.
- Initialized JS workers through a new helper that attaches message and error listeners before initialization handshake and enforces the existing ready timeout.
- Handled startup failures by rejecting on init or error events, cleaning up listeners and replacing dead workers with a retry path.
- Retried session creation with an inline worker after non-inline init failure so requests no longer stall on worker startup timeouts.
- Updated `init` handling to build a single-phase list from `items` when `list` is absent, using `phase` if provided or defaulting to `Tasks`.
- Kept the existing init validation behavior by emitting `Missing list for init operation` only when neither `list` nor `items` was supplied.
- Added tests for flattened init forms, including implicit phase defaulting, explicit phase use, and the missing-input error case.
- Added `jsonSchemaToTypeScript` and `renderToolInventory` to generate tool blocks with TypeScript signatures.
- Added `examples` and `TSchema` fields to dump-tool metadata and passed them through prompt rendering.
- Changed Harmony invocation rendering to omit `<|constrain|>json` markers in tool call payloads.
- Added compact native tool list-mode inventory rendering with full `# Tool:` output elsewhere.
- Added an abortOnFabricatedToolResult option to Agent and AgentLoopConfig to choose whether in-band fabricated tool results are aborted or drained.
- Propagated the option through agent loop wiring into wrapInbandToolStream so fabrication is aborted only when enabled.
- Exposed the setting in coding-agent as tools.abortOnFabricatedResult and wired it through session creation with a true default.
- Added model-to-syntax mapping in catalog with preferred tool-call syntax API.
- Added `ToolExample` typing and `ToolCallSyntax` exports across tool/grammar interfaces.
- Added syntax-aware tool example rendering through provider-specific grammar invocations.
- Added `exampleSyntax` context flow and example metadata so rendered prompts include examples.
- Added a `truncateFrom` option to `TreeListOptions` supporting `start` and `end` modes, defaulting to `end`.
- Updated `renderTreeList` to compute candidate items and summary placement based on truncation direction.
- Set the todo list renderer to use start-side truncation so collapsed todo output shows the tail entries first.
- Replaced large-paste wrap options with a single `<attachment>` wrapper action.
- Added explicit local-file attachment and inline paste choices to the selector.
- Updated the changelog to document the new large-paste action set.
- Added optional Agent and SDK tool-call syntax controls (`toolCallSyntax`, `PI_OWNED_TOOLS`) for owned calls.
- Added in-band grammar scanners and renderers for Anthropic, DeepSeek, GLM, Hermes, Kimi, PI, and Qwen3.
- Added supportsTools propagation and model schema updates to route unsupported models to fallback syntax.
- Replaced stream-markup parsing with syntax-specific in-band scanners and event conversion.
- Renamed line and block patch op verbs to XCHG, DEL, and INS in parsing and formatting.
- Updated grammar and tokenizer to support XCHG.BLK, DEL.BLK, and INS.PRE/POST/HEAD/TAIL forms.
- Updated diagnostics, docs, prompts, tests, and changelog to use XCHG/DEL/INS-based operators.
- Expanded session-stats parsing to normalize legacy op aliases to compact IDs.
- WelcomeComponent now lazily selected and cached a tip per instance, preserving it across re-renders.
- With the unicode preset, it showed a special nerdfont tip 10% of the time and otherwise used the regular tip rotation.
- Added tests that mocked theme preset and Math.random to verify standard and special tip selection behavior.
The pre-prompt context check ran compaction directly, so snapcompact (or
any strategy) fired before auto-promote ever got a chance — defeating
Auto-Promote Context. It now tries promotion to a larger-context model
first (mirroring the post-turn threshold path) and only compacts when no
target is available.
Auto and manual compaction now project a snapcompact result's
post-compaction size (kept history + frames at the image budget + summary
+ non-message overhead); when it still exceeds the model's usable window,
they downgrade to a context-full LLM summary instead of leaving the
session overflowing.
The external editor flow (Ctrl+G, plan editor, /todo edit) warned 'No
editor configured' on Windows because getEditorCommand() returned
undefined whenever neither $VISUAL nor $EDITOR was set — the default
state for most Windows shells.
Fall back to 'notepad' on win32 after consulting $VISUAL/$EDITOR
(always present in %SystemRoot%\\System32) and trim env values so
accidentally padded strings still resolve. POSIX still returns
undefined so the warning continues to nudge users to configure an
editor.
Fixes#2604
- Tracked seen-line provenance in snapshots and propagated it from read/search/ast-grep rows.
- Rejected hashline edits on unseen lines before patching, throwing unseen-line errors.
- Rejected single-line block anchors in strict mode and dropped them in unresolved lenient mode.
- Trimmed one-sided keeper-echo duplicates during multi-line replacements with warning output.
- Removed the streaming guard that previously rejected /tan while the parent response was still generating.
- Passed "deliverAs: \"nextTurn\"" when sending the background dispatch breadcrumb and kept "triggerTurn: false" so an in-flight turn is not steered.
- Skipped rebuilding chat messages during streaming sessions and updated tests to cover the non-blocking dispatch path.
- Fixed OAuth credentials to keep unknown fields in schema while preserving existing shape checks.
- Fixed MCP OAuth IDs to be profile-scoped and avoid deleting credentials from non-active profiles.
- Fixed string-flag parsing so PROFILE_BOOTSTRAP_BOUNDARY tokens are not consumed as values.
- Fixed active-profile directory resolution to refresh after env updates so profile .env overrides apply.
ExtensionRunner.emit shared the generic 30s EXTENSION_HANDLER_TIMEOUT_MS budget with every event, including the fire-and-forget session_shutdown teardown event extensions cannot observe. A hung third-party handler — observed on Windows with omp-discord-presence 0.1.2 waiting on a stuck Discord IPC pipe — held AgentSession.dispose() for the full window, making Ctrl+C look ignored for 30s.
session_shutdown now uses a dedicated 2s SESSION_SHUTDOWN_HANDLER_TIMEOUT_MS cap routed through a per-event handlerTimeoutForEvent() lookup so generic and shutdown budgets are independently configurable. The interactive-mode Ctrl+C path adds a defence-in-depth hard-exit: when isShuttingDown is true a fresh Ctrl+C exits with code 130 (the session JSONL has already been sync-flushed by the first press) instead of stacking another no-op shutdown() call.
Fixes#2600
- Added runtime hook resolvers so each `JsRuntime` instance can expose hooks for its active run.
- Patched `process.stdout` and `process.stderr` writes once per stream to route output chunks through active run text hooks and preserve existing worker logging when no run is active.
- Added chunk-to-string conversion for write payloads and encoding-aware forwarding while keeping callback semantics intact.
The workspace tree shown in the system prompt renders per-entry modification
times as render-time relative ages ("9m ago") computed from Date.now() on
every build. Those strings drift between sessions ("9m ago" -> "10m ago",
"59m ago" -> "1h ago") while the files themselves are unchanged. Because the
tree sits ahead of the (multi-thousand-token) tool block and KV cache is
contextual, that one early change invalidates the cached prefix for everything
after it, forcing a full prompt re-prefill on the first request of every new
session — even when nothing in the workspace actually changed.
Fix: render a deterministic absolute UTC timestamp (YYYY-MM-DD HH:MM) derived
purely from the file's mtime for the cached system-prompt tree, so the rendered
block is byte-identical across sessions and only changes when a file actually
changes. Scoped via a new internal AssembleOptions.ageMode:
- buildWorkspaceTree (cached system prompt) -> "absolute"
- buildDirectoryTree (read-tool output, not cached) -> "relative" (unchanged)
renderNode now takes a per-pass age formatter instead of reading Date.now()
directly.
Measured on a local llama.cpp server (single user, prompt cache on): with a
file whose age ticks between two back-to-back sessions, the unpatched build
re-prefills the full prefix on session 2 (27,124 prompt tokens, 46s); with this
change session 2 is a cache hit (13 tokens, 2s). Existing tests are unaffected
(they assert on filenames/order/elision, not on age strings); two regression
tests added.
- Collapsed the model list while the role/action menu is open and restored it when the menu closes.
- Limited rendered menu options to a terminal-derived visible window centered around the selected item.
- Added overflow handling via ScrollView with dynamic width and scrollbar when the option list exceeds available rows.
- Applied title-casing to `normalizeGeneratedTitle` outputs using a new internal helper.
- Adjusted tiny text and title generator tests to assert the new title-cased results.
- Added a new built-in `title` model role with `hidden` metadata and updated role definitions and schema.
- Updated title generation to resolve models in `title`, `commit`, then `smol` order and added test coverage for that precedence.
- Filtered hidden roles from selector badges and documented the new built-in role in model/settings docs.
- Updated the default `omp bench` prompt text to emphasize full-spectrum reasoning before answering.
- Required explicit enumeration of all four-table join orders with cost comparisons across nested-loop and hash joins plus index-scan versus full-scan tradeoffs.
- Expanded the changelog rationale to document sustained deliberation and exhaustive costing to avoid short-circuit benchmark responses.
- Updated CI dependency install flow to share bun cache orchestration across jobs.
- Added RustFS-backed bun cache restore/save script keyed by bun.lock hash.
- Updated the benchmark prompt to request a concrete, schema-driven query-optimization walkthrough with explicit selectivity, cardinality, join-order, and operator-cost calculations.
- Adjusted the output constraints to require plain-paragraph analysis output with no headings, lists, code fences, or tables.
- Documented the default benchmark prompt replacement in the package changelog under the Changed section.
