- Derived the `SEARCH_PROVIDER_ORDER`, `SEARCH_PROVIDER_PREFERENCES`, and `SEARCH_PROVIDER_LABELS` metadata dynamically from a single `SEARCH_PROVIDER_OPTIONS` source of truth.
- Reprioritized the default search provider sequence, shifting higher-order choices like Perplexity, Gemini, and Anthropic ahead of Tavily and Brave.
- Updated documentation to reflect the new search provider evaluation order.
- 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.
This change introduces a new `openrouter` API type and extensively refactors OpenAI-family streaming providers, centralizing shared logic and improving robustness.
Key changes include:
- **Unified OpenAI-family Logic:** Consolidated core utilities, compat resolution, request shaping, and stream processing into `openai-shared.ts`, reducing duplication across `openai-completions`, `openai-responses`, and `openai-codex-responses`.
- **OpenRouter API Type:** Introduced a dedicated `openrouter` API type with dual-surface compatibility, allowing it to dispatch requests as either OpenAI Chat Completions or Responses.
- **Enhanced Provider Integration:**
- Improved Perplexity search to leverage shared OpenAI streaming transports, including API-key fallback to OpenRouter and support for Perplexity's Responses API.
- Integrated xAI-specific logic directly into the shared `stream.ts` dispatch, removing the dedicated `xai-responses` provider.
- Refined credential parsing for Google Gemini CLI and handling of Azure deployment names.
- **Robustness & Consistency:** Improved error handling for Codex, standardized output token parameter resolution, and ensured consistent application of reasoning suppression across all Chat Completions dialects.
- **New Documentation:** Added `provider-endpoint-constraints.md` to detail endpoint-specific behaviors and quirks for various providers.
- **Telemetry & Debugging:** Extended telemetry propagation to advisor calls and overflow compaction tasks. Improved debugging for Codex WebSocket failures and stream error messages.
- **Tooling & Security:** Updated browser stealth scripts to prevent detection and added a new `ts-no-inline-cast-access` TTSR rule.
- Added PDF member read syntax (`doc.pdf:<member>`) and trailing-colon listing.
- Added asset-read handling to serve extracted PDF images as inline image content.
- Added PDF image extraction caching keyed by size and mtime with marker files for retries.
- Added basename validation that rejects unknown/traversal-like PDF members and shows available names.
- 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.
- Added a new `--advisor` flag to argument parsing and launch flag definitions.
- Applied the parsed `advisor` flag as a runtime-only override of `advisor.enabled` during startup.
- Updated advisor-related docs and added parseArgs tests for `--advisor` behavior and position handling.
Included JS and TS hookCapability results in extension path discovery so hooks under hooks/pre and hooks/post bind to the extension runner without explicit settings entries.
Fixes#2796
- 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.
- 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.
Break the Warp resize feedback-loop redraw storm by env-pinning resize classification. Merge resolves the issue-2088 test against #2755 by keeping the CMUX env-clearing setup and adding #2741's TERM_PROGRAM/PI_TUI_RESIZE_IN_PLACE neutralizers.
Load .github/instructions/*.instructions.md as rules. Includes review fix c509a5d59c: split comma-separated applyTo via parseCSV and treat **/* as an always-apply glob.
The non-multiplexer resize fast path borrows the alternate screen for
throwaway drag frames. Warp reports a terminal height one row different
for the alt buffer, so each alt enter/leave emits a fresh SIGWINCH that
re-enters the fast path — a self-sustaining loop that floods ED3 full
repaints with completely stable geometry (observed ~130
fullPaint(clearScrollback) frames over 15s, continuing after the drag
stopped). PI_FORCE_SYNC_OUTPUT cannot help (it is a loop, not tearing);
tmux works because the multiplexer path never toggles the alt buffer.
Route resize through the in-place repaint path (no alt-screen borrow, no
ED3 rewrap) for multiplexers and for terminals that re-report size on
alt-screen toggles, via resizeRepaintsInPlace(). Default-on for Warp,
overridable with PI_TUI_RESIZE_IN_PLACE=1|0. Tradeoff matches a
multiplexer: scrollback above the window keeps its old wrap.
Tests assert no alt-screen borrow / no ED3 across a Warp resize burst and
that the override toggles both ways; existing direct-terminal resize
tests now pin TERM_PROGRAM so they stay deterministic under Warp.
Added GitHub Copilot instruction-file discovery to the github rule provider path, mapping applyTo frontmatter into always-apply or glob-scoped rules and avoiding duplicate always-apply prompt content when context imports the same file.\n\nFixes #2731
Register tree-sitter-elisp in the shared AST language registry so
.el files infer the emacs-lisp grammar across blockRangeAt,
summarizeCode, astGrep/astEdit, and native aliases.
This fixes edit-tool block operations on top-level Emacs Lisp forms
instead of returning unsupported-language block errors.
- Add canonical emacs-lisp aliases and .el extension inference.
- Teach summaries to fold Lisp forms without grouping arbitrary lists.
- Map .el rendering and highlighting aliases through coding-agent/native.
- Cover defun, ERT, use-package, with-eval-after-load, pcase,
summary, astMatch, astEdit, and edit-tool insertion paths.
- Document the language and update package changelogs.
- Passed USER_INTERRUPT_LABEL through abort paths in collab, ACP, RPC, runtime, and SDK flows.
- Added userInitiated to synthetic continue inputs and session prompt calls.
- Suppressed advisor auto-resume during user aborts and preserved queued concerns.
- Cleared suppression on user prompts and reclaimed parked advisor cards on abort settle.

- Fixed parsing edge cases for comments, string escapes, nested args, and truncated blocks.
- 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 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.
