- 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.
- 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 a helper that renders hub output and extracts ordered agent IDs.
- Replaced positional string assertions with explicit row-order expectations.
- Awaited asynchronous theme initialization in test setup.
- 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.
- Updated default model identifiers across many catalog providers to newer model versions.
- Renamed a couple OpenAI compatibility provider descriptors, including Together and Zhipu coding-plan identifiers.
- Added multiple new OpenAI-compatible specialized provider descriptors for additional model provider families.
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 `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.
- 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 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.
- The AgentSession retry fallback test now validates the assistant message before reading it.
- It now verifies the first content block is text before checking the recovered message text.
- 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
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.
- Added beforeEach and afterEach hooks in mnemopi tests to set and clear MNEMOPI_NO_EMBEDDINGS so embeddings are skipped during those runs.
- Updated the bun-install cache script to archive only node_modules paths that exist as directories.
- 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 CI dependency install flow to share bun cache orchestration across jobs.
- Added RustFS-backed bun cache restore/save script keyed by bun.lock hash.
`ToolResultContent` is not exported from `@oh-my-pi/pi-ai`; `ToolResultMessage.content` is `(TextContent | ImageContent)[]`. Test only needs text, so type the content array as `TextContent[]`.
`#checkTodoCompletion` used to append a `<system-reminder>` and then call
`#scheduleAgentContinue`, so a text-only acknowledgement ("paused at your
instruction") triggered another `agent_end` that re-ran the same check and
fired the next reminder — counter ticked 1/3 → 2/3 → 3/3 inside a single user
pause without any user input. The user perceived three back-to-back reminders
appear from nowhere; the agent felt implicit pressure to invent busy-work or
take destructive ops to silence the loop.
Added `#todoReminderAwaitingProgress`: a reminder sets it, any `toolResult`
(real tool-level progress) or a new user prompt clears it, and
`#checkTodoCompletion` stays silent while it is set. Reset alongside
`#todoReminderCount` on user prompts, session reset, handoff, and the no-op
short-circuits in `#checkTodoCompletion` so the field never gets stuck.
Escalation through `todo.reminders.max` still works when the agent makes
tool-level progress between stops — that is the case the cap was designed for.
Regression coverage in `agent-session-todo-reminder-loop.test.ts` drives a
mocked `agent.continue` to mirror the bug-reported model behaviour and pins
the contract: exactly one reminder per user pause when the agent only
acknowledges; re-escalation when the agent actually calls a tool between stops.
