- Removes `model` field from task item/schema, TaskParams, and TaskItem types.
- Removes model selector validation, formatting, and approval display logic.
- Updates task tool priority docs to reflect that model is no longer per-call overridable.
- Updates eval agent() helper docs and prompt templates to remove model parameter.
- Updates tests to reflect removal of model override capability.
- Replaced the separate GUI-linked pi_natives.desktop.linux-x64 addon with
a pure-Rust X11 backend (x11rb RustConnection capture via RandR/GetImage,
XTest input with keysym mapping) compiled into the core addon on every
published target; Linux arm64 and musl are now supported and headless
hosts load the addon unaffected.
- Removed the native-desktop-linux cargo feature, desktop_unsupported.rs,
lazy desktop loader, second napi build, desktop packaging/CI steps, GUI
build dependencies, and the now-unreferenced vendored libspa crate;
reverted setup-system-deps to main.
- Preserved the desktop input hardening semantics on the unified backend:
XTest layouts reject negative origins and coordinates beyond 0..=32767,
batch coordinates stay bound to the frame last returned to JS with
intermediate screenshots deferred, coordinate input requires a
previously returned frame, and failed chord releases still release
every held key.
- Enforced a 60s worker-side execute deadline (DESKTOP_DEADLINE_EXCEEDED):
no input is emitted after expiry and wait-heavy batches are rejected
upfront.
- Added int32 fail-closed validation for coordinates, drag points, and
scroll deltas at the JS ingress and gateway schema.
- Exposed computer to models without native OpenAI computer-use support as
a regular function tool with a typed GA action schema across OpenAI,
Azure, and Codex Responses providers, including named forced choice.
- Added the /computer slash command (on/off/status/toggle) for
session-only enablement via runtime tool registration in SessionTools.
- Updated docs, changelogs, and contract tests accordingly.
- Replaced single-provider preferences with ordered priority lists for web search and image generation.
- Added a `MultiSelectSubmenu` component supporting toggle and reordering interactions in settings.
- Implemented migration logic to convert legacy single-provider preferences into ordered priority lists.
- Updated setup wizard scenes, image generation fallback logic, and search provider chains to use priority lists.
Added TCP server transport for vscode-js-debug and recursively handled startDebugging requests, breakpoint synchronization, active child routing, and tree cleanup.
Fixes#5984
- Added the `xd://` virtual device protocol (`internal-urls/xd-protocol.ts`, `tools/xdev.ts`): tools declaring `loadMode: "discoverable"` are unmounted from the request tools array and driven via `read xd://` (list/docs+schema) and `write xd://<tool>` (execute), gated by the `tools.xdev` setting (default on) and inlined into the system prompt.
- Merged the `irc`, `job`, and `launch` tools into a single `hub` tool (`tools/hub/`, `async/job-manager.ts`): messaging keeps `send`/`inbox`/`list`, job control maps to `wait`/`cancel`/`jobs`, process supervision keeps `start`/`logs`/`stop`/`restart`/`describe` with `ps`, and the unified `wait` races background jobs against peer messages; SDK `IrcTool`/`JobTool`/`LaunchTool` are replaced by `HubTool`.
- Removed the hidden `resolve` tool in favor of the `xd://resolve`/`xd://reject`/`xd://propose` resolution devices, auto-including `write` whenever a deferrable tool or plan mode is present.
- Removed the BM25 tool-discovery system: the `search_tool_bm25` tool, the `tool-discovery` module, the `tools.discoveryMode`/`mcp.discoveryMode`/`mcp.discoveryDefaultServers`/`tools.essentialOverride` settings, per-tool MCP selection, and the `mcp_tool_selection` message type.
- Unified tool presentation on `ToolLoadMode` (`essential`|`discoverable`), replacing the custom-tool `xdev?: boolean` opt-out; custom, extension, MCP, RPC host, image-generation, and TTS tools now default to `discoverable`, and added a `satisfies` predicate to `SoftToolRequirement`.
- Removed the standalone `ssh` command tool and `ssh/ssh-executor` (the `ssh://` read/write/search protocol stays), and made `--tools` address hidden built-ins.
- Updated collab-web to render `xd://` dispatches and `hub` op families, dropped the `search_tool_bm25`/`ssh`/`report-finding` renderers, refreshed tool docs and prompts, and migrated the affected tests and changelogs.
- Updated prewalk gating in `AgentSession` to key the todo gate on active tools instead of registry presence, so deactivated todo tools no longer block prewalk handoff.
- Changed subprocess tool filtering so `todo` is stripped for normal subagents but retained when prewalk is armed, and propagated the prewalk state through tool-session setup.
- Added regression tests for restricted active-tool slates and prewalk/non-prewalk subagent tool propagation to verify todo is handled correctly in each case.
The agent:// path segment was always treated as a jq JSON-extraction key
against <parent>.md, so agent://Parent/Child loaded Parent.md and applied
.Child instead of resolving the nested child capsule Parent.Child.md. A
precise-planner reading its own scout child therefore got Not found.
The slash is now a hierarchy separator first: agent://Parent/Child resolves
Parent.Child.md (subagent children are allocated as dot-qualified ids). It
falls back to JSON extraction only when no nested output matches the path;
the ?q= query form is always extraction.
Fixes#5238
- Replaced legacy `pi/` role alias prefix with canonical `@` syntax across model resolution, documentation, and tests.
- Added support for bare `*` default alias and multiple alias prefix detection with custom role resolution in `resolveConfiguredRolePattern()`.
- Enhanced thinking suffix parsing to accept unambiguous abbreviations (minimum 2 characters) for effort and level selectors.
- Extended `resolveCliModel()` and `filterAvailableModelsByEnabledPatterns()` to accept settings parameter for role alias resolution from `--model` flag.
- Introduced a project-scoped `launch` tool to orchestrate long-running services, debuggers, and watchers with persistent execution capabilities.
- Implemented a robust daemon broker with Unix/Windows IPC transport that manages process lifecycles, readiness monitoring, and automatic log rotation.
- Added detached process support to ensure services persist independently of the main application lifecycle, including recovery and cleanup mechanisms.
- Updated the `bash` interceptor to prioritize the new `launch` tool for background processes and provided comprehensive documentation for lifecycle and signal handling.
- Removed the bash command fixup system and associated logic from both the Rust and TypeScript components.
- Deleted the redundant fixup module and its exported implementations.
- Updated technical documentation and configuration settings to reflect the removal of pre-execution bash command rewriting.
- Enabled granular task execution by allowing batches to interleave blocking items with non-blocking async background spawns.
- Updated task orchestration to support simultaneous inline result collection and persistent background job tracking.
- Improved agent visibility in the job tool by reporting running subagents even when not explicitly linked to a backing job ID.
- Enhanced terminal state handling to prevent premature tool block closures while async background operations remain active.
- Renamed task wire fields, replacing `assignment` and `description` with `task` and `name` while removing `role` references.
- Implemented automated task UI label generation using a tiny model to replace manual role descriptions.
- Updated task execution and rendering logic to support per-item agent resolution and dynamic badge display.
- Migrated schemas, prompts, and test suites to enforce the new flat task structure and agent-centric policy.
- Added six new search providers (Bing, Yahoo, Ecosia, Startpage, Mojeek, and Public) to expand coverage and parallel search capabilities.
- Implemented a unified `browserFetch` utility with headless-browser fallback and randomized Chrome profiles to improve scrape reliability.
- Integrated automated bot-defense mechanisms including CAPTCHA detection, ALTCHA proof-of-work, and homepage-token flows.
- Fixed hanging search CLI commands by ensuring proper closure of AuthStorage connections.
- Removed the `plan` agent definition and associated prompt file from bundled agents.
- Updated documentation to reflect the removal of `plan` from available subagents.
- Cleaned up related tests to remove references to the deprecated agent.
Documented the 1-3600 second bash timeout clamp in the schema, model-facing prompt, and tool docs, including the async timeout behavior.
Added coverage that the shipped schema and rendered prompt expose the contract.
Fixes#4408
Added providers.webSearchGeminiModel and GEMINI_SEARCH_MODEL so Gemini web_search requests use a selected grounding model while keeping gemini-2.5-flash as the fallback.
Covered OAuth, Developer API, and missing modelVersion fallback paths in Gemini web search tests.
Fixes#4312
Clarified hashline minus-row errors and model-facing prompt examples so Markdown list rows use the + body-row prefix instead of triggering write fallbacks.
Fixes#4179
Added root omp docs for memory_edit, learn, manage_skill, generate_image, and tts, plus package-level coverage for user-facing README-only CLIs.
Added a docs-index freshness check to package check and made gen:bundle generate and reset the docs embed itself.
Fixes#3934
- Renamed references to the `quick_task` subagent to `sonic` across docs, agent definitions, prompts, and test files.
- Updated the parallel file analysis tool to spawn `sonic` subagents instead of `quick_task`.
- Documented the breaking change in the changelog along with additions and removals of other built-in subagents.
The DuckDuckGo provider hit api.duckduckgo.com (the Instant Answer API),
which only serves Wikipedia / Wolfram-Alpha-style topics — empty
AbstractText / Results / RelatedTopics for the vast majority of agent
queries. The orchestrator then rejected the empty response and surfaced
'DuckDuckGo returned no renderable search content', leaving users with
no working free fallback.
Switch the provider to POST html.duckduckgo.com/html/ (the no-JS HTML
frontend) with a browser User-Agent, parse the result blocks (unwrapping
//duckduckgo.com/l/?uddg=… redirect URLs), and map recency to the df
form field (d/w/m/y). When DuckDuckGo serves the bot-detection modal
(HTTP 200/202 with anomaly-modal body) we surface a clear
SearchProviderError so the orchestrator can fall through to the next
provider with cause attached.
Fixes#3799
- Renamed the `find` and `search` tools to `glob` and `grep` respectively across the codebase to improve command clarity.
- Implemented full-stack support for the renamed tools, including CLI arguments, system prompts, SDK exports, and tool registration.
- Added automated migration logic in `settings` to transform legacy `find` and `search` configuration keys to their new equivalents.
- Updated the `collab-web` renderer registry to ensure backwards compatibility with legacy tool outputs.
- Added tree-sitter markdown support to resolve headings into full sections in `pi-ast`.
- Enabled block operations (`SWAP.BLK`, `DEL.BLK`, `INS.BLK.POST`) on markdown headings so they encompass the entire section, including nested deeper headings.
- Updated system prompt to guide agents in using structured markdown heading edits for plans.
- Fixed `plan-mode-guard` to correctly resolve local protocol options for subagents.
- Removed deprecated eval prelude helpers `append`, `tree`, `diff`, `sort`, `uniq`, and `counter` from all supported runtimes.
- Cleaned up runtime implementations, protocol definitions, and UI rendering logic associated with the removed helpers.
- Updated project documentation, prompts, and test suites to reflect the reduced helper API surface.
- Recorded functional changes in the package changelog.
- Refactored `todo` tool to accept a single operation object instead of an `ops` array.
- Implemented parameter normalization to maintain backward compatibility with legacy array-based tool calls.
- Updated tool instructions, documentation, and UI rendering components to reflect the new interface.
- Added compatibility tests to verify rendering and execution for both legacy and current operation formats.
The eval agent() helper used `agent_type`/`return_handle` (snake_case) in
Python/Ruby/Julia and `agentType`/`returnHandle` (camelCase) in JS, forcing
the prelude docs to repeat every option twice ("JS same but camelcased").
Both are now single lowercase words identical across all four runtimes, and
`agent` matches the `task` tool's existing agent-selection parameter.
- Renamed across py/js/rb/jl preludes (signatures, forwarding, docstrings).
- Renamed the `__agent__` bridge wire protocol + `EvalAgentArgs` (`agentType`
→ `agent`, `returnHandle` → `handle`) so no prelude-side remap is needed.
- Updated prompt docs (workflow-notice.md, tools/eval.md), repo docs
(docs/tools/eval.md, docs/python-repl.md), and all bridge/prelude tests.
- CHANGELOG: Breaking Changes entry under [Unreleased].
- Removed the `readHashLines` setting to consolidate hashline display logic.
- Simplified `resolveFileDisplayMode` to derive hashline visibility solely from the active edit mode.
- Added automatic cleanup of the `readHashLines` key from existing configuration files.
- Implemented `waitForSelector` and `waitForNavigation` methods in the browser tool API.
- Introduced per-operation fail-fast budget management with dynamic timeout clamping.
- Added validation for selector engines to reject unsupported Playwright-only platform features.
- Standardized error handling to provide descriptive, named timeouts for stalled browser operations.
