Anthropic released Claude Code v2.1.269, introducing new evaluation tools for plugins, a sub-agent visualization in VSCode, and extensive stability improvements across terminal and cloud sessions.
- Added `claude plugin eval` to run plugin eval suites with JSON and HTML reports.
- Introduced an agent map in VSCode to visualize sub-agents and manage their transcripts.
- Fixed prompt cache invalidation issues when responses are cut off or sessions are resumed after interruption.
- Resolved terminal cursor, fullscreen, and escape code rendering regressions in kitty, WezTerm, and rxvt-unicode.
- Corrected permission rule application for deny/ask rules starting with `!` and Bash tee command paths.
- Improved prompt suggestion filtering for Japanese, Chinese, and Korean text without spaces.
These updates enhance plugin development workflows, improve IDE integration visibility, and fix critical session state and terminal rendering bugs.
