- Added shared auth storage and model registry for concurrent and eager compaction tests.
- Replaced per-test auth storage creation and cleanup routines with shared lifecycle management.
- Removed local auth storage variables and individual cleanup hooks from test harness instances.
- Added `splitAddressableFileLines` to strip terminal newlines from line addressability without removing genuine blank lines.
- Updated coding-agent read tool context parsing to use addressable file lines.
- Prevented `formatNumberedLines` from appending a synthetic empty line when encountering a terminal newline.
- Added tests to ensure trailing newlines do not generate addressable blank lines.
- Added a post-apply syntax advisory warning when an edit breaks parsing on files that previously parsed cleanly.
- Implemented Rust-specific single-quote lexing in `computeDelimiterBalance` to correctly handle lifetimes and character literals.
- Added test suites covering rust lifetime delimiter counting and the post-apply parse advisory behavior.
- Updated eager compaction and plan reference tests to track call indices and task delegation markers instead of text strings.
- Removed obsolete context message marker checks, vibe mode assertions, and prompt gating test cases.
- Simplified prewalk, workflow, and Gemini instruction test expectations across agent modules.
- Removed the system prompt personality test suite entirely.
- Added archive and member size assertion limits along with path byte-length checks for PAX and GNU metadata targets.
- Added support for global PAX attributes, old-GNU name records, and signed GNU base-256 numeric header fields.
- Updated archive reading in WriteTool to accept a filesystem path instead of buffered bytes.
- Added test coverage for signed GNU base-256 values, PAX extensions, overlong path rejections, and oversized archives.
- Bound PAX sparse record memory overhead by caching sparse markers and specific keys.
- Update system prompt phrasing and tests for tool inventory and date displays.
- Added Google provider thinking configuration parameters and force-reasoning-off controls.
- Implemented MCP SSE stream resumption using Last-Event-ID and `SSEResumeError`.
- Added support for TAR old-GNU sparse extension blocks, path length checks, and archive entry overrides.
- Restricted external thinking support to specific models and added semver fallback parsing.
- Added the `--external-thinking` CLI flag alongside model capability checks to gate external thinking tool availability.
- Updated Anthropic and Google transports to honor `forceReasoningOff` for native thinking-off controls.
- Renamed the `thoughts` property and parameter to `notes` across think fixtures, tools, and tests.
- Updated system prompt instructions and test suites to verify transport-specific thinking and tool activation.
- Capped directory-alias rewrites per lookup (ELOOP-style, 40) so a directory
symlink targeting its own subtree (a -> a/b) throws a catchable ToolError
instead of looping forever growing the path.
- Deferred pending tar link resolution while any directory on the target path
is itself an unresolved link, and rewrote targets through established
directory aliases before the exact-path lookup, so file symlinks routed
through directory aliases materialize instead of dangling.
- Regression tests reproduce both shapes: pre-fix the aliased symlink read
failed with 'cannot be materialized' and the self-cycle read hung.
- Refactored and condensed numerous system prompts, agent instructions, and tool documentation files across packages.
- Streamlined workflow rules, formatting constraints, and execution guidelines for improved clarity and brevity.
- Updated discovery rules, recommendation criteria, and syntax standards in prompt templates.
- Update the ty parser regex to correctly match file path and position before the severity and error code.
- Adjust discovery prompt documentation and test cases to match the revised ty output format.
- Added a markdown template defining a tool-only turn directive for Gemini models.
- Appended the forced tool directive to request contents when using Antigravity Gemini routes with forced tool mode.
- Added discovery subagent and custom checker specifications for alternative toolings across multiple languages.
- Implemented interactive TUI flows for target picking and free-form request discovery.
- Added output parsers for popular static analysis and linting tools.
- Increased default maximum subagents cap and documented the new capabilities.
