- Implemented a queueing mechanism in `ToolExecutionComponent` to prevent starvation of edit previews during high-frequency argument updates.
- Replaced eager cancellation of in-flight diff computations with a drain loop that ensures every update is processed once the current compute settles.
- Added `partialJsonOf` helper to safely narrow streamed JSON buffers from tool arguments.
- Added regression test to verify that slow diff computations are not aborted by incoming stream chunks and instead queue a subsequent re-run.
- Implement cleanup logic to drop `thinkingSignature` values from assistant thinking blocks during persistence.
- Identify and drop signatures only when the underlying reasoning data is already recoverable via the `providerPayload` items.
- Ensure orphaned signatures that cannot be reconstructed from the payload are preserved during serialization.
- Add comprehensive test coverage to verify deduplication safety and edge-case handling for missing payloads.
- Added missing `noteDisplayableThinkingContent` mock function to test fixtures.
- Included `markActivityStart` and `markActivityEnd` methods in status line mocks to match updated controller interfaces.
- Removed the architectural restriction limiting advisors to read-only tools.
- Updated advisor configuration to permit any built-in tool, including `edit`, `write`, and `bash`.
- Defaulted advisor toolsets to `read`, `grep`, and `glob`, while maintaining strict session isolation for each advisor.
Preserved extension-registered provider and model header objects so request-time reads observe later mutations instead of registration-time snapshots.
Fixes#3725
The SSH renderer previously declared 'provisionalPendingPreview: "collapsed"',
which only opted the COLLAPSED pending shape out of the transcript's
stable-prefix ratchet. Once the user expanded an in-flight SSH preview (ctrl+o)
and the framed block outgrew the viewport, the pending rows became
ratchet-eligible and committed to native scrollback before the result render
inserted the 'Output' section. The settled render then re-anchored the frame,
producing two distinct stranded shapes in history:
- a stale 'pending SSH: [host]' header pinned above the final '<- SSH: [host]'
frame (header variant), and
- the pending bottom border row reused in-place as the new 'Output' separator,
with a fresh '...' footer pushed below it (footer variant).
Flip 'provisionalPendingPreview' to 'true' so every pending shape — collapsed
or expanded — is treated as provisional and stays out of native scrollback
until the result render commits a settled frame. The 'collapsed'-only opt-out
remains correct for renderers (bash, eval) whose expanded pending preview is
top-anchored and survives the result render without re-anchoring.
Added two contract tests asserting expanded pending SSH is commit-unstable
and that bash/eval expanded pending preview is still commit-stable — keeping
the opt-in renderer-scoped.
Fixes#3714
Changed legacy SSE pending requests to reject with a transport-closed error when the persistent stream ends, preserving MCP tool reconnect-and-retry behavior.
Fixes#3710
Rejected legacy SSE endpoint events whose resolved URL uses a different origin than the configured SSE URL, preventing configured headers from being posted cross-origin.
Fixes#3710
- Introduced guest snapshot reconciliation to maintain host state consistency during session switching.
- Improved yield tool reliability by implementing incremental schema validation and strict parameter enforcement.
- Fixed a calculation edge case in the status line to prevent negative time values during activity tracking.
- Expanded the test suite with new validation for session interruption, collab state synchronization, and process error handling.
- Added regression test in `remote-compaction` to verify that concurrent v2 compaction preparation correctly reuses preserved history and avoids redundant re-expansion.
- Added mock-backend verification in `session-storage` to ensure that failed atomic title updates do not rollback newer optimistic state.
- Updated `sql-session-storage` expectations to account for the preserved fixed-width title slot header in session files.
- Expanded `remote-compaction` fetch header validation to include `x-client-request-id` assertion.
Added the MCP protocol 2024-11-05 HTTP+SSE transport so type:"sse" opens the endpoint stream, posts JSON-RPC to the announced endpoint, and correlates streamed responses.
Fixes#3710
Replaced the controller-side switchActiveModel flag with a currentContextTokens hint on AgentSession.setModel, so the over-context decision is computed against the refreshed candidate metadata. setModel returns whether the live switch happened, and the Alt+M default-role path uses that to gate the live side effects.
- Added logic to `assembleYieldResult` to automatically accumulate incremental yields into arrays for schema-identified array properties.
- Updated `YieldTool` to bypass schema validation for incremental stream yields, allowing partial data emissions that don't satisfy the full output schema yet.
- Enhanced `YieldTool` parameter declaration to remove blocking top-level JSON schema combinators, ensuring compatibility with strict-mode providers (OpenAI/Codex).
- Updated `parseYieldType` to gracefully handle `null` type values emitted by strict providers for untyped final yields.
- Added regression tests for array-valued findings alignment and strict-mode tool schema compatibility.
Decoupled default-role persistence from live model switching when the selected model is below the current session context window.
Updated the model selector regression coverage so the Alt+M Default action remains selectable and advances to thinking selection.
Fixes#3708
- Updated the demotion logic to treat complete, signed thinking blocks as stable content that terminates an interrupted stream.
- Protected signed thinking runs from being stripped when processing interrupted agent messages.
- Added `getForceFileSuggestions` and `shouldTriggerFileCompletion` to `AutocompleteProvider` interface.
- Updated `Editor` to invoke file completion logic dynamically when providers support it.
- Corrected log viewer scroll offset calculation to account for viewport height.
- Added comprehensive unit test for log row selection and expansion.
- Implemented mouse wheel scrolling and click interaction for log entries.
- Added cursor navigation and expansion toggling via click in the log viewer.
- Updated help text to reflect available mouse controls.
- Updated `convertToLlm` to detect and strip trailing thinking runs from user-interrupted assistant messages.
- Retained original thinking content on the persisted assistant message to ensure UI state (render, reload, and rebuild) remains intact.
- Added `followedByInterruptedThinking` helper to verify continuity message presence before stripping for the provider request.
- Updated persistence tests to confirm thinking remains in the session state but is excluded from LLM context headers.
- Replace the static "Goal/Next" status line with an ephemeral LLM-generated summary triggered after idle periods.
- Hook the recap into the agent's side-channel pipeline, using live goal and task state as context anchors for meaningful recaps.
- Implement abort logic so that active user interactions immediately cancel pending recaps and discard late-arriving responses.
- Added `statusLine.compactThinkingLevel` setting to render the thinking level as a leading icon.
- Replaced the verbose ` · <level>` suffix with a single glyph when compact mode is enabled.
- Updated the status line controller and component to resolve and propagate the new configuration.
- Refactored test assertions to use loadEntriesFromFile for session file parsing.
- Verified forked session content using entry type discrimination instead of line-based parsing.
- Introduced V2 streaming remote compaction for OpenAI-compatible models, enabling full conversation history forwarding and reducing data loss from local trimming.
- Added comprehensive support for sessionId, promptCacheKey, and automatic retry mechanisms to improve compaction reliability and accuracy.
- Updated agent, catalog, and configuration schemas to manage V2 streaming settings, model metadata, and model-specific context window constraints.
- Extended freeform tool patch support for Azure OpenAI and Codex models and refined assistant-side history preservation across providers.
- Extracted taskToolRenderer to a dedicated renderer file to resolve circular dependencies.
- Updated all references to the renderer to point to the new location.
- Extended `tools/yield.ts` with typed incremental sections, raw last-turn terminal results, and updated yield guidance in the subagent system prompts.
- Reworked `task/executor.ts`, `task/render.ts`, and `task/types.ts` to assemble typed yield sections, render reviewer results from incremental yield data, and preserve the typed result shape.
- Switched `prompts/agents/reviewer.md`, `review-request.md`, and `review-custom-request.md` from `report_finding` calls to incremental `yield` sections.
- Added incremental-yield coverage in `test/task/executor-warnings.test.ts`, `test/task/render-yield-shape.test.ts`, `test/tools/yield-extraction.test.ts`, and `test/tools/yield.test.ts`.
- Added `INTERRUPTED_THINKING_MESSAGE_TYPE` and `demoteInterruptedThinking` in `session/messages.ts` for stripping unfinished thinking into durable context.
- Persisted hidden interrupted-thinking context from `session/agent-session.ts` immediately after user-interrupted assistant turns.
- Added the `prompts/system/interrupted-thinking.md` envelope used for replaying interrupted reasoning.
- Added focused interrupted-thinking coverage in `test/agent-session-interrupted-thinking.test.ts` and `test/session/interrupted-thinking-demote.test.ts`.
- Implemented mutable session titles with audit tracking, including storage persistence for SQL and Redis backends.
- Added comprehensive session management features such as idle recap triggers, incremental subagent yield submissions, and automated title refreshing.
- Enhanced task tracking in the TodoTool with progress prioritization and improved session cleanup logic.
- Introduced citation tag handling for OpenAI-compatible source markers and improved edit parsing.
Split image-bearing custom messages into developer text plus user image content before provider conversion so queued skill images stay out of developer slots.
