Implements Phase 1 of A2A protocol support as discussed in #12007:
- A2A types (agent config, task, message, artifact types)
- A2aHub service for managing agent connections
- delegate_to_agent tool for delegating tasks to external agents
- Manual configuration via a2a_settings.json (global/project)
- Configurable headers for authentication (JSON key-value pairs)
- Integration with system prompt, tool parser, and ClineProvider
- A2A tool group added to code mode
- Tests for A2aHub service

* chore: treat extension .env as optional (#11116)
* fix: sanitize tool_use_id in tool_result blocks to match API history (#11131)
Tool IDs from providers like Gemini/OpenRouter contain special characters
(e.g., 'functions.read_file:0') that are sanitized when saving tool_use
blocks to API history. However, tool_result blocks were using the original
unsanitized IDs, causing ToolResultIdMismatchError.
This fix ensures tool_result blocks use sanitizeToolUseId() to match the
sanitized tool_use IDs in conversation history.

* fix(cli): resolve race condition causing provider switch during mode changes (#11205)
When using slash commands with `mode:` frontmatter (e.g., `/cli-release`
with `mode: code`), the CLI would fail with "Could not resolve
authentication method" from the Anthropic SDK, even when using a
non-Anthropic provider like `--provider roo`.
Root cause: In `markWebviewReady()`, the `webviewDidLaunch` message was
sent before `updateSettings`, creating a race condition. The
`webviewDidLaunch` handler's "first-time init" sync would read
`getState()` before CLI-provided settings were applied to the context
proxy. Since `getState()` defaults `apiProvider` to "anthropic" when
unset, this default was saved to the provider profile. When a slash
command triggered `handleModeSwitch()`, it found this corrupted profile
with `apiProvider: "anthropic"` (but no API key) and activated it,
overwriting the CLI's working roo provider configuration.
Fix:
1. Reorder `markWebviewReady()` to send `updateSettings` before
`webviewDidLaunch`, ensuring the context proxy has CLI-provided
values when the initialization handler runs.
2. Guard the first-time init sync with `checkExistKey(apiConfiguration)`
to prevent saving a profile with only the default "anthropic"
fallback and no actual API keys configured.

* feat: extract translation and merge resolver modes into reusable skills (#11215)
* feat: extract translation and merge resolver modes into reusable skills
- Add roo-translation skill with comprehensive i18n guidelines
- Add roo-conflict-resolution skill for intelligent merge conflict resolution
- Add /roo-translate slash command as shortcut for translation skill
- Add /roo-resolve-conflicts slash command as shortcut for conflict resolution skill
The existing translate and merge-resolver modes are preserved. These new skills
and commands provide reusable access to the same functionality.
Closes CLO-722
* feat: add guidances directory with translator guidance file
- Add .roo/guidances/roo-translator.md for brand voice, tone, and word choice guidance
- Update roo-translation skill to reference the guidance file
The guidance file serves as a placeholder for translation style guidelines
that will be interpolated at runtime.
* fix: rename guidances directory to guidance (singular)
* fix: remove language-specific section from translator guidance
The guidance file should focus on brand voice, tone, and word choice only.
* fix: remove language-specific guidelines section from skill file
* Update .roo/skills/roo-translation/SKILL.md

* feat: add Claude Opus 4.6 support across all providers (#11224)
* feat: add Claude Opus 4.6 support across all providers
Add Claude Opus 4.6 (claude-opus-4-6) model definitions and 1M context
support across Anthropic, Bedrock, Vertex AI, OpenRouter, and Vercel AI
Gateway providers.
- Anthropic: 128K max output, /5 pricing, 1M context tiers
- Bedrock: anthropic.claude-opus-4-6-v1:0 with 1M context + global inference
- Vertex: claude-opus-4-6 with 1M context tiers
- OpenRouter: prompt caching + reasoning budget sets
- Vercel AI Gateway: Opus 4.5 and 4.6 added to capability sets
- UI: 1M context checkbox for Opus 4.6 on all providers
- i18n: Updated 1M context descriptions across 18 locales
Also adds Opus 4.5 to Vercel AI Gateway (previously missing) and
OpenRouter maxTokens overrides for Opus 4.5/4.6.
Closes#11223
* fix: apply tier pricing when 1M context is enabled on Bedrock
When awsBedrock1MContext is enabled for tiered models like Opus 4.6,
also apply the 1M tier pricing (inputPrice, outputPrice, cache prices)
instead of only updating contextWindow. This ensures cost calculations
and UI display use the correct >200K rates.

* fix: prevent parent task state loss during orchestrator delegation (#11281)
* fix: make removeClineFromStack() delegation-aware to prevent orphaned parent tasks (#11302)
* fix: make removeClineFromStack() delegation-aware to prevent orphaned parent tasks
When a delegated child task is removed via removeClineFromStack() (e.g., Clear
Task, navigate to history, start new task), the parent task was left orphaned
in "delegated" status with a stale awaitingChildId. This made the parent
unresumable without manual history repair.
This fix captures parentTaskId and childTaskId before abort/dispose, then
repairs the parent metadata (status -> active, clear awaitingChildId) when
the popped task is a delegated child and awaitingChildId matches.
Parent lookup + updateTaskHistory are wrapped in try/catch so failures are
non-fatal (logged but do not block the pop).
Closes#11301
* fix: add skipDelegationRepair opt-out to removeClineFromStack() for nested delegation

* fix(reliability): prevent webview postMessage crashes and make dispose idempotent (#11313)
* fix(reliability): prevent webview postMessage crashes and make dispose idempotent
Closes: #11311
1. postMessageToWebview() now catches rejections from
webview.postMessage() so that messages sent after the webview is
disposed do not surface as unhandled promise rejections.
2. dispose() is guarded by a _disposed flag so that repeated calls
(e.g. during rapid extension deactivation) are no-ops.
3. CloudService mock in ClineProvider.spec.ts updated to include
off() — a pre-existing gap exposed by the new dispose test.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix: add early _disposed check in postMessageToWebview
Skip the postMessage call entirely when the provider is already disposed,
avoiding unnecessary try/catch execution. Added test coverage for this path.

* fix: resolve race condition in new_task delegation that loses parent task history (#11331)
* fix: resolve race condition in new_task delegation that loses parent task history
When delegateParentAndOpenChild creates a child task via createTask(), the
Task constructor fires startTask() as a fire-and-forget async call. The child
immediately begins its task loop and eventually calls saveClineMessages() →
updateTaskHistory(), which reads globalState, modifies it, and writes back.
Meanwhile, delegateParentAndOpenChild persists the parent's delegation
metadata (status: 'delegated', delegatedToId, awaitingChildId, childIds) via
a separate updateTaskHistory() call AFTER createTask() returns.
These two concurrent read-modify-write operations on globalState race: the
last writer wins, overwriting the other's changes. When the child's write
lands last, the parent's delegation fields are lost, making the parent task
unresumable when the child finishes.
Fix: create the child task with startTask: false, persist the parent's
delegation metadata first, then manually call child.start(). This ensures
the parent metadata is safely in globalState before the child begins writing.
* docs: clarify Task.start() only handles new tasks, not history resume
* fix: serialize taskHistory writes and fix delegation status overwrite race (#11335)
Add a promise-chain mutex (withTaskHistoryLock) to serialize all
read-modify-write operations on taskHistory, preventing concurrent
interleaving from silently dropping entries.
Reorder reopenParentFromDelegation to close the child instance
before marking it completed, so the abort path's stale 'active'
status write no longer overwrites the 'completed' state.
Covered by new tests: RPD-04/05/06, UTH-02/04, and a full mutex
concurrency suite.

* chore: clean up repo-facing mode rules (#11410)

* fix: address PR review comments
- Replace any[] with TodoItem[] type in ExtensionStateContext.tsx for better type safety
- Remove redundant initialTodos parameter from startTask call in Task.ts (todos already set in constructor)
- Improve code clarity in newTaskTool.ts by checking provider reference early and reusing state
# Conflicts:
# src/core/task/Task.ts
# webview-ui/src/context/ExtensionStateContext.tsx
* fix: revert order of operations in startTask to fix integration test timeout
The change in order of operations (calling say() before postStateToWebview()) was causing the XML content file test to timeout. Reverting to the original order fixes the issue.
* fix: hide todos parameter from new_task tool prompt when experiment is disabled
- Modified getNewTaskDescription to completely omit todos parameter when experiment is off
- Updated tests to verify todos parameter is not shown at all when disabled
- Ensures tool prompt remains unchanged when experimental setting is disabled
- Maintains backward compatibility while providing cleaner prompt interface
* fix: update snapshots for new_task tool todos parameter
- Updated snapshots in add-custom-instructions.spec.ts
- Updated snapshots in system-prompt.spec.ts
- All tests now passing with the new todos parameter documentation
* feat: move newTaskRequireTodos from experimental to VSCode settings
- Added newTaskRequireTodos as a VSCode configuration property in src/package.json
- Added description in src/package.nls.json
- Updated newTaskTool.ts to read from VSCode configuration instead of experiments
- Removed NEW_TASK_REQUIRE_TODOS from experimental settings in src/shared/experiments.ts
- Removed newTaskRequireTodos from packages/types/src/experiment.ts
- Updated tests to use VSCode configuration mocking instead of experiments
- Removed references from experiments test file
- Maintains backward compatibility (defaults to false)
* fix: make new_task tool description dynamically reflect VSCode setting
- Updated new-task.ts to check args.settings instead of args.experiments
- Added newTaskRequireTodos to SystemPromptSettings interface
- Pass newTaskRequireTodos setting through Task.ts and generateSystemPrompt.ts
- Updated all related tests to use settings instead of experiments
- Fixed TypeScript errors in test files by adding newTaskRequireTodos property
This ensures the tool description correctly shows todos parameter as required/optional
based on the VSCode setting value, fixing the issue where Roo would try to use
new_task without the todos parameter when it was required.
