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

- 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].

- Updated `DEFAULT_ESSENTIAL_TOOL_NAMES` to include these tools by default.
- Updated documentation and tests to reflect the change in default essential tool availability.
Fixes#3165
- Implemented `tab.ariaSnapshot()` to capture and represent page structures as ARIA-tree YAML.
- Introduced `tab.ref()` and ref-based selector parsing to enable precise element interaction via unique ARIA identifiers.
- Integrated automated script bundling for cross-environment evaluation of ARIA snapshot logic.
- Updated browser action methods to resolve and target elements using ARIA-ref handles.
- Implement JSON repair and strict argument validation to sanitize raw payloads and redact sensitive information from agent event logs.
- Add automatic authentication fallback for benchmark model resolution to ensure consistent performance testing across providers.
- Refactor search tool API parameters by replacing `i` with a case-sensitive `case` boolean flag for clarity.
- Update session history formatting to ensure empty objects are consistently serialized as `{}` instead of empty strings.
- Removed the customizable `timeout` parameter from the tool schema and implementation.
- Fixed the timeout duration to 5 seconds to simplify tool usage.
- Updated documentation and error messages to advise narrowing search patterns instead of adjusting timeouts.
- Switch all UI components and tests from sharp box corners (`boxSharp`) to rounded ones (`boxRound`).

- Remove outdated architectural notes regarding forced tool-choice queues in documentation.
- Standardized elision markers across all tool outputs and filters to use cohesive `[...N [type] elided...]`, `[...Nln elided...]`, and `[...xB elided...]` syntax.
- Updated documentation, prompts, and test expectations to reflect the unified elision format.
- Improved transcript viewer robustness by preventing content aliasing through path-inclusive signature hashing.
- Added logic to clear stale transcript content when associated session files are deleted, accompanied by verifying test cases.
- Centralized decoding of tmux's `extended-keys` control sequences (`csi-u` and `xterm` formats) into a shared utility.
- Updated the multi-line editor and single-line input to use this decoder, preventing escape tails (e.g., `[27;5;106~`) from leaking into the text buffer.
- Added parity to the single-line input by explicitly stripping any remaining control characters after decoding to ensure data integrity.
- Removed the `fflate` dependency in favor of using `node:zlib` for ZIP operations.
- Updated documentation and internal code comments to reflect the transition to native `node:zlib` DEFLATE support.
- Centralized archive operations into a new `utils/zip.ts` module with unified support for ZIP, tar, and tar.gz formats.
- Optimized ZIP reading using lazy, ranged central-directory access and implemented ZIP64 support for large files.
- Hardened archive extraction with directory traversal protection and configured memory limits for loading and extraction.
- Refactored tool-specific logic to utilize the new centralized utility and deleted the redundant `archive-reader.ts`.
- Derived the `SEARCH_PROVIDER_ORDER`, `SEARCH_PROVIDER_PREFERENCES`, and `SEARCH_PROVIDER_LABELS` metadata dynamically from a single `SEARCH_PROVIDER_OPTIONS` source of truth.
