- Improved browser script evaluation to handle both expression and statement forms by adding fallback evaluation logic, fixing failures for certain script types.
- Migrated console.error() calls to structured logger.warn() and logger.error() throughout codebase.
- Updated os.tmpdir() import style in browser tool from destructured to namespace import.
- Enhanced skipped file messages to include file size information for better user visibility.
- Updated auto-read skip messages to display actual file size when files are too large to process.
- Inlined MAX_CLI_TEXT_BYTES calculation for improved code clarity.
using declaration disposes synchronously after return evaluates the
promise expression but before it settles, killing the child process
and producing empty stdout. Adding await ensures the process completes
before Symbol.dispose fires.
- Fixed bash tool hanging with background jobs by implementing timeout-based cancellation and draining stdout/stderr pipes instead of waiting indefinitely for EOF.
- Fixed crash when auto-reading large @mentions by adding file size validation (5MB for text, 25MB for images) before reading file contents.
- Prevented out-of-memory issues by skipping files exceeding size limits and displaying file size information in UI for skipped files.
- Added GB file size formatting support to handle very large files in human-readable format.
- Added file size display in UI for skipped files to inform users why files were not included.
- Added test case verifying bash executor returns correctly when command spawns background jobs.
- Clarified that subagents automatically inherit full system prompt including AGENTS.md, context files, and skills -- do not repeat project rules or conventions in task context.
- Updated task context guidance to focus on session-specific information subagents lack, eliminating redundant documentation of project constraints already available to them.
- Refined constraints template to emphasize task-specific rules and session decisions rather than global project conventions.
- Expanded anti-patterns section to explicitly flag redundant context that wastes tokens by repeating AGENTS.md rules, project constraints, and tool preferences.
