v16.0.0

@oh-my-pi/pi-agent-core

Breaking Changes

• Renamed owned tool-calling options from toolCallSyntax/exampleSyntax to dialect/exampleDialect.


• Changed compaction conversation serialization to use the target model's native dialect turn, thinking, tool-call, and tool-result envelopes when a dialect is selected.


• Renamed the owned dialect environment variable from PI_OWNED_TOOLS to PI_DIALECT.

Added

• Added onTurnEnd hook support (setOnTurnEnd/onTurnEnd) to run awaited per-turn bookkeeping with current messages before the next model request and skip callback execution for aborted or error turns

Changed

• Renamed toolCallSyntax option to dialect in AgentOptions and AgentLoopConfig


• Updated conversation serialization to use dialect's native transcript rendering when a dialect is selected


• Changed internal references from ToolCallSyntax type to Dialect type across agent loop and compaction modules

@oh-my-pi/pi-ai

Breaking Changes

• Renamed the public dialect entrypoint from @oh-my-pi/pi-ai/grammar to @oh-my-pi/pi-ai/dialect.


• Renamed grammar dialect identifiers from ToolCallSyntax to Dialect, renamed the Grammar interface to DialectDefinition, and renamed Grammar.syntax to DialectDefinition.dialect.


• Added DialectDefinition.renderThinking and DialectDefinition.renderTranscript so dialect implementations serialize complete native chat transcripts, not just tool call/result blocks.

Added

• Added renderTranscript method to dialect definitions for serializing complete native chat transcripts


• Added renderThinking method to dialect definitions for rendering thinking/reasoning blocks


• Added support for 11 dialect implementations: Anthropic, DeepSeek, Gemini, Gemma, GLM, Harmony, Hermes, Kimi, Pi-native, Qwen3, and XML


• Added createInbandScanner factory function to instantiate dialect-specific scanners


• Added getDialectDefinition function to retrieve dialect implementations by name


• Added renderToolCatalog and renderInbandToolPrompt functions for tool catalog rendering


• Added renderToolInventory function to generate human-readable per-tool documentation with examples


• Added renderToolExamples function to render tool usage examples in the model's native dialect


• Added encodeInbandToolHistory function to encode tool call history in dialect-specific format


• Added wrapInbandToolStream function to process streaming responses with in-band tool call parsing


• Added ThinkingInbandScanner for parsing thinking/reasoning blocks across dialects


• Added OwnedStream class for managing dialect-aware streaming with tool call events


• Added in-band thinking channels to every dialect that was missing one: gemini (a ```thinking fence mirroring ```tool_code), gemma (its native <|channel>thought…<channel|> reasoning channel), kimi (<think>…</think>), and pi (<thinking>…</thinking>). Each scanner now parses reasoning into thinking events instead of leaking chain-of-thought into the visible reply, and every dialect's renderThinking is a real channel that round-trips back through its scanner (no passthrough renderers).

Changed

• Moved public dialect entrypoint from @oh-my-pi/pi-ai/grammar to @oh-my-pi/pi-ai/dialect in package exports


• Updated internal imports in stream-markup-healing.ts to use new dialect module path


• Changed renderToolInventory to demote a tool description's own markdown headers by one level when it contains a top-level # header, so they nest under the wrapping # Tool: <name> heading instead of reading as sibling sections. Descriptions that already start at ## and headers inside fenced code blocks are left untouched.

Fixed

• Fixed Gemini, Gemma, Kimi, and Pi in-band scanners to respect parseThinking: false, leaving private reasoning markers in visible text when parsing is disabled


• Fixed thinking-channel parsing for streaming Gemini, Gemma, Kimi, and Pi outputs so split or partial <thinking> blocks no longer leak into visible replies


• Fixed in-band thinking finalization and Kimi stream-healing interactions so leaked <think> blocks are preserved when structured tool calls are present, not duplicated when explicit reasoning is present, and closed on stream flush.

Removed

• Removed src/grammar/factory.ts (replaced by src/dialect/factory.ts)


• Removed src/grammar/rendering.ts (functionality moved to src/dialect/rendering.ts)


• Removed src/grammar/xml.ts (replaced by src/dialect/xml.ts)

@oh-my-pi/pi-catalog

Breaking Changes

• Renamed the catalog-owned tool syntax API from ToolCallSyntax/FALLBACK_TOOL_SYNTAX/preferredToolSyntax to Dialect/FALLBACK_DIALECT/preferredDialect.

@oh-my-pi/pi-coding-agent

Breaking Changes

• Renamed the SDK tool format type and resolver from ToolCallFormat/resolveToolCallSyntax to DialectFormat/resolveDialect, and the agent option from toolCallSyntax to dialect.


• Changed /dump transcript output to render messages with the selected model's native dialect turn and thinking envelopes instead of markdown role headings.

Added

• Added advisor.syncBacklog setting (off, 1, 3, 5) to pause turn completion until advisor review backlog drops below the threshold, with a maximum 30-second wait


• Added advisor backlog synchronization at turn end when enabled so the main session stays aligned with the advisor's pending review turns


• Added automatic discovery of WATCHDOG.md files from user and project locations so advisor guidance from local watchdog instructions is appended to its system prompt


• Added /advisor on, /advisor off, /advisor status, and /advisor dump [raw] slash-command subcommands to manage the advisor at runtime


• Added advisor.enabled and advisor.subagents settings to enable the advisor and extend it to spawned task/eval subagents


• Added advisor status badge (++ in success color) to the status line when an advisor is active


• Added /dump [raw] flag to toggle between compact and legacy uncompact transcript output formats


• Added /advisor on, /advisor off, and /advisor status slash-command subcommands to enable or disable the advisor at runtime and view advisor status metrics


• Added a passive advisor: assign a second model to the advisor role and enable advisor.enabled to have it silently review each primary turn and inject severity-tagged advice notes via the advise tool. A nit rides the non-interrupting aside queue (batched into one card at the next step boundary), while a concern or blocker interrupts the running agent through the steering channel — aborting in-flight tools, or resuming the agent when it has already yielded — so high-severity advice is acted on immediately. Advice renders in the primary transcript as a distinct Advisor card, and the advisor gets hard-isolated read-only read/search/find access — bound to its own ToolSession so its reads never touch the primary's snapshot/seen-lines caches — to investigate the workspace before weighing in. The status line shows a ++ badge (in the success color, kept distinct from the model name) after the model name while an advisor is active, and /advisor dump copies the advisor's own transcript to the clipboard. Advisors are created only for the top-level session by default; enable advisor.subagents to extend them to spawned task/eval subagents.


• Animated "thinking" pulse (·‥…‥) shown in place of a hidden thinking block while the model is actively reasoning, so streaming progress is visible even with hideThinkingBlock enabled.

Changed

• Changed advisor prompting guidance to emit at most one advise per update and to prefer silence when the agent is on track


• Changed /dump default output to compact markdown format; use /dump raw for the legacy uncompact format


• Changed /dump and /advisor dump to default to compact transcript output and accept an optional raw flag for the legacy uncompact format


• Session dump output now renders message history using the model's native dialect turn envelope instead of markdown role headings


• Changed RPC, RPC-UI, and ACP hosts to default the advisor settings off instead of inheriting a user's interactive-session advisor preference.

Fixed

• Fixed advisor backlog tracking so failed advice prompts do not stall catch-up indefinitely by dropping pending backlog after repeated consecutive failures


• Fixed backlog accounting to decrement only after successful advisor prompts so sync waits correctly reflect advisor progress


• Fixed advisor context batching to still send pending review updates when context maintenance fails instead of dropping the batch


• Fixed explicit advisor enablement to clear protocol-default overrides so enabling the advisor applies immediately


• Fixed advisor message card notes getting truncated to two lines when the card is collapsed.


• Fixed advisor context handling to maintain its token budget by promoting or compacting/restarting advisor context while preserving advisor reasoning-off settings.


• Fixed startup.quiet leaving MCP and LSP startup status events visible during launch ().

What's Changed

• fix: align tool cache paths with XDG dirs by


• fix(coding-agent): respect startup.quiet for startup statuses by
