- Added LaTeX math and Mermaid allowances in terminal and final-chat prompts.
- Added inline math tokenization in TUI for $, $$, \(\), and \[\].
- Added LaTeX-to-Unicode conversion helpers and exports for math rendering.
- Fixed inline math detection to skip escaped dollars and currency-like spans.
- Rewrote `formatSessionDumpText` in `session-dump-format.ts` to emit the pre-16.x full dump: system-prompt prelude, model/thinking config, tool inventory with parameters, and the transcript as markdown role headings (`## User`, `## Assistant`, `### Tool Call`/`### Tool Result`), reusing `renderDelimitedThinking` for `<thinking>` blocks.
- Dropped the compact default and the `[raw]` flag from `/dump`: removed the `isRaw` parameter from `handleDumpCommand` in `command-controller.ts`, `interactive-mode.ts`, and `types.ts`, and removed the `inlineHint: "[raw]"`/`compact` plumbing in `builtin-registry.ts`.
- Updated the `formatSessionAsText` doc comment in `agent-session.ts` to describe the verbose dump shape.
- Removed the obsolete `formatSessionDumpText raw thinking` suite from `advisor.test.ts` and refreshed `session-dump-format.test.ts` to assert the verbose dump output.
- Recorded the revert in the coding-agent changelog and trimmed `/dump` from the compact transcript tool-intent-prefix entry.
- Introduced advisory note output as `<advisory>` tags with optional severity and guidance.
- Updated session transcript formatting to `### Session update` and inline watched role labels.
- Added shared `escapeXmlText` utility and escaped XML-sensitive text in advisor outputs.
- Added one-shot success run token metrics and one-shot statistics reporting.
- Added an includeToolIntent option to session history formatting to control intent comments.
- Updated tool call rendering to prefix call lines with a leading comment when the tool argument contains a non-empty intent field.
- Enabled intent rendering in advisor history updates and added tests for intent-on and intent-off output paths.
- Renamed ToolCallSyntax type to Dialect and Grammar interface to DialectDefinition across all packages.
- Moved grammar directory to dialect and updated all import paths in agent, ai, catalog, and coding-agent packages.
- Added renderTranscript and renderThinking methods to DialectDefinition, enabling native dialect-aware conversation serialization.
- Consolidated rendering utilities into new dialect/rendering.ts with shared helpers for ChatML, legacy text, and dialect-specific formatting.
- Updated conversation serialization in agent and coding-agent to use dialect.renderTranscript() for native turn envelope rendering.
- 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.
- 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 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.
- Fixed `/dump` output (`session-dump-format.ts`) and the RPC `get_state` `dumpTools` payload (`rpc-mode.ts`) serializing Zod schema instances — leaking `def`/`shape` internals and stringified methods — by converting parameters through `zodToWireSchema` like providers receive.
- Fixed context-usage token estimation stringifying the Zod `def` tree, which overcounted tool schema tokens in the status line.
- Fixed tool-discovery indexing (`tool-index.ts`) returning empty `schemaKeys` for Zod tools, weakening BM25 ranking; keys are now recovered via wire conversion.
- Fixed the extension inspector panel rendering "(no arguments)" for Zod tools by reading properties off the converted wire schema.
- Added coverage in `tool-index.test.ts` plus new `context-usage.test.ts` and `session-dump-format.test.ts`, and a changelog entry.
Registers a HistoryProtocolHandler with the internal URL router: history:// lists every registered agent (id, status, kind, last activity) and history://<agentId> renders a concise markdown transcript (tool calls collapsed to one line each, thinking elided). Live refs render from the in-memory message array; parked refs load read-only from the JSONL session file via loadSessionMessagesReadOnly (no writer, no lock). System prompt + read tool prompt + docs/tools/read.md learn the new scheme.
Move bundled models, model cache/manager, thinking metadata, effort helpers,
provider descriptors/discovery, wire constants, and model identity utilities
into the new @oh-my-pi/pi-catalog package.
Update pi-ai to keep provider runtime/auth concerns, move catalog provider
metadata into CATALOG_PROVIDERS, and migrate coding-agent, agent, stats, docs,
and tests to import catalog values from pi-catalog.
Split coding-agent model registry helpers into discovery, roles, and models
config modules while preserving registry orchestration.
BREAKING CHANGE: @oh-my-pi/pi-ai no longer exports catalog subpaths such as
/models, /model-cache, /model-manager, /model-thinking, /effort,
/provider-models*, discovery helpers, and provider wire constants; use the
matching @oh-my-pi/pi-catalog subpaths instead.
- Introduced `AsideMessage` as a message-or-thunk union so aside providers can defer injection decisions.
- Updated agent loop handling to resolve aside thunks at injection time and skip entries that returned `null`, then switched the session yield queue to `drainLazy` for deferred message building.
- Added tests validating lazy aside evaluation and staleness-aware dropping when everything becomes stale after dequeueing.
- Added an agent loop test proving aside messages are delivered after tool results, before the next model request, without interrupting tool execution.
- Added a yield-queue test confirming stale entries are excluded, the queue is cleared, and re-draining yields no messages.
- Added a new SessionManager.forkFrom test confirming terminal breadcrumb suppression while cloning source session history under a new parent session.
- Updated TanCommandController test fixtures with required assistant message API, provider, model, and completion metadata.
- Added image-reference rendering to make `[Image #N]` placeholders clickable in chat.
- Added MIME-aware image blob materialization with extensioned sidecar paths.
- Added clickable path, line, and URL hyperlinks for read, search, and fetch outputs.
- Hardened OSC8 hyperlink emission with URI validation and control-byte/idempotency checks.
- Added `IndexedSessionStorage` with `SessionStorageBackend` for index-based storage reads.
- Removed `readTextSync` from the public `SessionStorage` API and sync backends.
- Changed Redis and SQL backends to warm `{size, mtimeMs}` metadata and read via `readTextSlices`.
- Added per-path write queues and `drain()` to serialize operations and surface first failures.
- Classified each session's final message as done, interrupted, aborted, error, or pending from a 32 KiB tail read.
- Rendered the status as a colored segment on the session metadata line.
- Added `peekFileTail` and `readTextSuffix` across storage backends to read file tails in one pass.
- Simplified `MemorySessionStorage` to a string array mirror with a sidecar mtime map.
- Column truncation is now applied to a cloned array so `collectedLines` retains on-disk content for snapshot recording.
- Snapshots bound to hashline TAGs now hold the original file text, preventing hash-mismatch failures on subsequent edits to files with long lines.
- Added regression tests covering full-file, range, multi-range reads and a live edit-after-read scenario.
Two TS errors in CI:
1. `agent-session.ts:1317` — `error TS1345: An expression of type 'void'
cannot be tested for truthiness`. The listener type is
`(event: AgentSessionEvent) => void`, so the returned value can't be
directly tested. Same shape in `agent.ts:1079`.
2. `test/session/emit-listener-isolation.test.ts:19` — the test fixture
for `AgentEvent.tool_execution_start` was missing the required `args`
field.
Cast the return to `unknown` and check `instanceof Promise` instead of
duck-typing `.then` — type-safe and matches what async functions actually
return. Add `args: {}` to the test fixture.
Both `AgentSession.#emit` (session/agent-session.ts) and `Agent.#emit`
(packages/agent/src/agent.ts) iterated listeners with no error isolation.
A synchronous throw in any subscriber aborted the for-loop, so later
subscribers (TUI rendering, ACP bridge, task executor progress,
hindsight) silently missed events. Many listeners — see
`modes/controllers/event-controller.ts:141` and
`modes/controllers/input-controller.ts:576` — are registered as
`async (event) => { await this.handleEvent(event); }`; the returned
Promise was dropped, so any rejection became an unhandled rejection.
Wrap each listener invocation in try/catch and attach a `.catch` to any
returned thenable. Errors are logged via `logger.warn` (already imported
in agent-session.ts) and `console.error` (agent.ts has no logger
dependency, keep it that way).
Test: new `test/session/emit-listener-isolation.test.ts` registers two
listeners on both classes; first listener throws (or returns a rejecting
Promise); asserts the second listener still receives the event AND no
`unhandledRejection` fires. 4 cases (sync+async × Agent+AgentSession).
All fail on current main; all pass with the fix.
- Added optional `onBeforeYield` configuration and `setOnBeforeYield` in Agent, executed before follow-up checks.
- Added `YieldQueue` to `AgentSession`, with setup/teardown and streaming/idle flush via `setOnBeforeYield`.
- Replaced immediate async-result follow-up dispatch with queued batch entries, including stale-state suppression.
- Added MCP follow-up queueing in SDK, deduplicating updates by `serverName` and `uri`.
- Added changelog entries for `onBeforeYield`, async-result batching, MCP dedupe, and `display.shimmer` modes.
- Added yield queue unit tests for streaming emission, debounced idle batches, stale filtering, and error isolation.
