Limited the optional LM Studio /api/v0/models metadata lookup with an abort timeout and started the catalog request independently so OpenAI-compatible servers without the native endpoint still refresh. Added a regression for hung native metadata probes.\n\nFixes #2945
Queried LM Studio native /api/v0/models metadata during catalog and runtime discovery so type=vlm models advertise image input. Added regressions for both provider-manager and runtime discovery paths.\n\nFixes #2945
- Integrated comprehensive loop guard support for DeepSeek and assistant prose patterns, including configurable stream checks.
- Implemented Moonshot Flavored JSON Schema (MFJS) normalization for improved tool compatibility and enum type inference.
- Added support for Ollama reasoning effort backfilling and Grok-specific service tier cost tracking across providers.
- Expanded model catalog with new entries and unified compatibility logic for improved OpenRouter API integration.
- Migrated all wire protocol, schema definitions, and tools validation from Zod to ArkType across multiple packages.
- Updated extension runtimes, custom tools loader, and TypeBox compatibility shim to expose and use ArkType instances.
- Added a comprehensive ArkType migration guide, validation parity tests, and helper utilities.
- Removed redundant PDF asset routing and parsing implementations from the read tool.
- Added new `tui.tight` setting with default `false` and documented behavior.
- Added global tight-mode APIs and `setIgnoreTight` propagation across Box, Text, and Markdown.
- Handled `tui.tight` updates to refresh UI borders and trigger rerendering.
- Updated key message components to ignore tight mode selectively and preserve intended spacing.
- Tracked completed primary turns in `AgentSession` and started an immune-turn window after each interrupting advisor steer.
- Routed follow-on `concern`/`blocker` notes to the aside channel while the immune window is active, while preserving prior auto-resume-suppressed handling.
- Added the `advisor.immuneTurns` setting and tests for immune-turn detection and delivery-channel decisions.
- Updated `executeSearch` to read `providers.antigravityEndpoint` once and catch uninitialized-settings errors, so web search fallback no longer aborts before any provider runs.
- Added missing `Vision` and `Git` entries to `TAB_GROUPS` so those new settings now render in their intended setting-section groups.
- Adjusted context and idle-compaction tests to wait for prompt-in-flight transitions and provide `getContextUsage` for deterministic snapshots during pending turns.
- Updated getApiKey signatures to accept a Model and return ApiKey or ApiKeyResolver.
- Updated stream key handling to resolve credentials per model and use seedApiKeyResolver for retries.
- Added antigravityEndpointMode setting with auto/production/sandbox endpoint selection.
- Added 429/5xx endpoint failover for Gemini stream, usage, search, and image calls.
Added a git.enabled setting and skipped footer/status-line git probes when integration is disabled or no git-backed status segment is rendered.
Fixes#2847
- Added `images.describeForTextModels` configuration defaulting to true for text models.
- Added `describeAttachedImagesForTextModel` to persist images and generate local:// descriptions.
- Added image-description notices to session flow with hidden typing and pre-user insertion.
- Added fallback behavior that returns notes when vision is unavailable or output is empty.
- Changed `select_folded_spans` to skip an unfold candidate that exceeded `unfold_limit` and continue processing the remaining BFS queue instead of breaking.
- Added a regression test in `summary.rs` proving a large `<style>` raw-text span no longer starves sibling HTML sections from unfolding.
- Updated the summary unfold-ceiling setting description to document that overflowed candidates stay folded while BFS continues.
- Removed the Codex-preferred canonical remapping path for exact `provider/id` model matches.
- Resolved explicit `openai/gpt-5.5` references as `openai` provider without redirecting to `openai-codex`.
- Added regression tests to confirm explicit provider/id and enabled-model patterns are not coalesced to Codex.
Limit provider-priority ranking to provider defaults that share the first fallback default id, preserving mixed-provider startup precedence while keeping the OpenAI/Codex tie fix.\n\nFixes #2807
Route stale OpenAI GPT default roles through canonical Codex selection when the catalog prefers the Codex OAuth transport, and rank shared provider defaults by canonical provider priority.\n\nFixes #2807
- Removed render_mermaid from tool discovery, task definitions, and registries.
- Removed renderMermaid setting and prompt/docs references tied to the deleted tool.
- Added maxWidth and theme color options to Mermaid ASCII resolution in markdown flow.
- Re-rendered Mermaid ASCII in both directions and clipped output to available width.
Install a subagent's ordered model candidates as child-session retry fallback chains so a retryable provider failure advances to the next candidate instead of killing the worker (issue #2750).
The routing bypass in matchModel() returned early for any provider whose
post-slash id contained a valid @slug, so fuzzy provider-qualified patterns
over non-aggregator ids that legitimately end in @ (e.g. google-vertex/opus@default
-> claude-opus-4-8@default) resolved to nothing. Gate the bypass on
providerModels.some(supportsUpstreamRouting) so only OpenRouter / Vercel Gateway
short-circuit to the routing fallback. Addresses Codex review feedback on #2710.
Kept OpenRouter and Vercel upstream routing suffixes in subagent retry fallback selectors so same-base routed candidates stay distinct.
Resolved retry fallback candidates from the raw selector before model switching so routed fallback models keep their requested upstream route.
Prevented provider-scoped fuzzy matching from consuming OpenRouter @upstream selectors whose slug also appears in the model id.
Added resolver coverage for openrouter/deepseek/deepseek-v4-pro@deepseek:high so the upstream routing block and thinking level are both preserved.
Fixes#2708
- Added the missing `ui.group` property to the `plan.defaultOnStartup` setting schema entry.
- Recorded the fix in the coding-agent changelog under the Fixed section.
- Added awaited `onTurnEnd` and `setOnTurnEnd` wiring for turn-end callbacks.
- Added `advisor.syncBacklog` settings (off/1/3/5) and documented 30-second catch-up caps.
- Fixed advisor runtime backlog handling with failure counters, waiters, and retry requeue.
- Updated agent sessions to enqueue advisor updates on turn end and removed direct `turn_end` branch logic.
- Added advisor context maintenance hook and token estimation before prompting for auto-upkeep.
- Added re-prime replay handling to reset advisor context and recover deferred prompts.
- Implemented session-level context compaction with model promotion and snapcompact-first fallback summarization.
- Surfaced advisor settings in the model tab and updated advisor system guidance text.
- Created AdvisorRuntime and AdviseTool to drive a read-only advisor agent that delivers severity-tagged advice (nit, concern, blocker) with interruption policy and transcript delta rendering.
- Added /advisor slash command with on/off/status/dump subcommands to control advisor lifecycle and inspect advisor metrics (model, messages, tokens, cost).
- Added advisor.enabled and advisor.subagents settings to enable passive advisor review on main agent and spawned task/eval subagents.
- Implemented advisor message rendering with severity-color badges (blocker=error, concern=warning, nit=muted) in chat log and status line indicator (++ badge).
- Extended yield-queue and session-history-format to support advisor batching and optional thinking block inclusion.
- 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.
- 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 `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.
- 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 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 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.
Read vLLM max_model_len and OpenAI-compatible context_length metadata during model discovery, route providers.vllm.baseUrl into built-in discovery before cached models exist, and avoid sending local placeholder bearer tokens.
Scope the vLLM model cache to the discovery base URL so endpoint changes refetch immediately, and add focused regression coverage for configured and built-in vLLM discovery.
Add a proxy-discovery regression: a `context_length: 0` upstream value
must be rejected by `toPositiveNumberOrUndefined` and fall back to the
default window. Raw `??` would have pinned it at 0 (nullish coalescing
does not skip 0), so this guards the should-fix the helper was added for.
Also apply biome formatting to the discovery change (collapse the
multiline `contextWindow:` expression, drop a trailing space) and the new
tests so `biome check` passes — the PR as submitted failed the formatter.
Addresses review feedback on #2466.
Updated model discovery to use `context_length` reported by the API when available, falling back to bundled reference data and default. Added `context_length` field to parsed model response and modified context window assignment logic.
