When a bash tool call requests a timeout outside the allowed 1-3600s
range, the effective clamped value and the originally requested value
are now emitted as a notice appended to the tool output and exposed on
BashToolDetails via requestedTimeoutSeconds. The renderer shows the
clamped+requested pair inline in the timeout badge.
- Queued outbound JSON-RPC messages behind a per-client promise queue to serialize writes.
- Added a project-load gate for project-aware LSP operations before diagnostics and reference lookups.
- Retried declaration-only references with a short delay until project metadata is available, then proceeded with normal results.
- Relaxed chunk-mode parameter validation to accept `{path}`-only edits as valid delete operations.
- Updated the invalid-parameters help text to document accepted chunk delete payloads.
- Added a test that verifies a bare `{path}` edit removes the targeted chunk when null values are stripped.
- Added a streaming parser path for apply_patch envelopes that tolerates incomplete patch bodies.
- Updated apply patch preview expansion to return best-effort hunks when the renderer is in partial mode.
- Added a renderer test confirming streaming apply_patch input shows file paths without end-marker parse errors.
- Added built-in model entries for gpt-5.5 and gpt-image-2, including updated context windows, token limits, and pricing.
- Updated generated-model policy application to set or clear applyPatchToolType based on inferred GPT-5 freeform rules.
- Changed Spark edit-mode resolution to return apply_patch by default, honoring explicit replace and strict-mode overrides.
- Added tests for GPT-5 freeform policy inference and Spark edit-mode default, variant, and strict-mode behavior.
Slots a new "apply_patch" variant alongside the existing edit modes
(replace, patch, hashline, chunk, vim). The mode accepts a single input
string containing a Codex *** Begin Patch / *** End Patch envelope,
parses it with a new lenient parser (heredoc-tolerant), and fans each
file-op out to the existing executePatchSingle so LSP writethrough,
plan-mode guards, fs-cache invalidation and diagnostics are shared
with the patch mode.
Exposes both tool shapes from the spec: the JSON function-tool variant
(§1.2, {input: string}) and the OpenAI custom-tool / Lark-grammar
"freeform" variant (§1.1, raw patch string). The edit tool advertises
a Lark grammar via customFormat and a wire name via customWireName;
openai-responses emits it as a grammar-constrained custom tool when a
model opts in with applyPatchToolType: "freeform" in models.json.
custom_tool_call / custom_tool_call_output are plumbed end-to-end
through the shared responses code (emission, streaming, history
replay), and the agent-loop dispatcher matches tool calls by either
name or customWireName so returned calls route correctly.
Also threads preview/diff rendering for apply_patch through the TUI
(tool-execution + edit renderer) so streaming patches show per-file
diffs like the other edit modes.
Default edit mode is unchanged (hashline); opt in via edit.mode or
PI_EDIT_VARIANT=apply_patch.
- Standardized missing-file read errors and now return `File not found: <path>` for absent edit targets.
- Centralized AI provider, usage, and OAuth helpers into shared modules to remove duplicated logic.
- Migrated OAuth/API-key login flows to shared factory helpers and removed inline prompt/token-exchange code.
- Reused shared tools and formatter utilities for discovery, stream tails, LSP batching, and source formatting.
- Consolidated repeated test helpers and fixtures into shared modules, replacing inline helper duplicates.
- Added a new read.toolResultPreview boolean setting defaulting to false to control inline read result rendering.
- Updated read tool group rendering to show inline previews only when enabled and to hide duplicate summary rows for previewed entries.
- Passed the setting through event and UI helper constructors and added tests for default-off behavior and the duplicate-preview summary case.
- Refactor path normalization to combine expandPath and normalizeLocalScheme
- Add validation in utils.ts to reject local:// paths as filesystem paths
- Fix bash-skill-urls regex to handle hyphen-prefixed local:/ patterns
- Add tests for hyphen-prefixed and @local: patterns
- Add negative lookbehind to regex in bash-skill-urls to prevent matching local:/
inside paths like /repo/local:/PLAN.md
- Normalize local scheme before expanding paths in path-utils
- Add test cases for both changes
Expands the regex pattern to match local:/ (single-slash) URLs in addition to local:// (triple-slash), preventing potential Linux path leaks.
- Add regex patterns for single-quoted, double-quoted, and unquoted local:/ URLs
- Add test coverage for all three quote styles
Removed unconditional topic:news coupling in buildRequestBody that scoped
Tavily index to news publications whenever recency was set. Technical queries
with --recency now search the general index filtered by time only.
Tightened SearchParams.recency contract in base.ts: providers MUST interpret
recency as a pure time filter and MUST NOT change topic scope as a side effect.
Three fixes to make CI green after the opus 4.7 and auto-bump landed:
1. github-copilot model mapper: prefer capabilities.limits.max_prompt_tokens
over the root-level context_length field (which mirrors max_context_window_tokens, i.e.
total window). Copilot's real /models response returns both for the gpt-5.x family, and
context_length inflates contextWindow with the output budget. Also restore the bundled
Copilot limits (claude-opus-4.6, gpt-5.2, gpt-5.4, gpt-5.4-mini, grok-code-fast-1) to
the values the fixed mapper produces so tests that depend on truthful offline fallbacks
pass. Update the two Copilot discovery tests whose payloads conflated context_length
with prompt capacity.
2. coding-agent task schema: make the per-task assignment description context-mode-aware.
The previous description unconditionally told agents that 'shared background belongs
in context', which is wrong for independent mode where shared context is disabled.
3. coding-agent model-registry test: update the anthropic-latest canonical collapse case
to claude-opus-4-7 since opus 4.7 is now the newest official opus in models.json.
- Updated todo start handling to set the requested task to in_progress while demoting all other in_progress tasks to pending.

- Documented UUIDv7 session handling and OpenAI cache-routing fixes in package Unreleased changelogs.
The tests were using the old { sel, op, content } format which is no longer
recognized after the edit tool consolidation. Updated to use the new
{ path: 'file:selector', write/insert } format.

- Added rollback handling for pending INSERT-mode changes whenever a non-final kbd sequence leaves insert mode, and updated the resulting VimInputError with guidance for using `insert` and escaping insert transitions.
- Hardened VimTool execution by resetting stale insert state before processing commands and by only applying empty inserts when Vim remains in INSERT mode.
