Claude Code v2.1.265: Plugin Directory Support, 1GB Tool Result Cap, and More

Anthropic shipped Claude Code v2.1.265, a maintenance release with several notable additions and a long list of bug fixes aimed at plugin management, telemetry, and reliability.

Key Additions

• Plugin folder support – You can now point --plugin-dir at a folder containing multiple plugins. Each child folder with a manifest loads, and plugins added or removed while running are picked up automatically.
• 1 GB cap on tool results – Results saved to disk are now limited to 1 GB. If a result is truncated, the in-conversation preview indicates that the saved file was truncated.
• Unified telemetry – Claude Desktop and Cowork now send user.email and user.groups through the Claude apps gateway, matching terminal sessions.

Bug Fixes Worth Noting

• Prompt-cache reuse fixes – Resuming a foreground-spawned subagent no longer changes its tool list and system prompt prefix, preserving cache reuse. Similarly, agent teammates and resumed subagents keep SubagentStart hook context and preloaded skills in the prompt prefix.
• Resume after crash during tool call – The last prompt is no longer rewritten, and the interrupted tool call is kept and marked as interrupted.
• Command-line fixes – /model opusplan[1m] no longer fails with "Model not found." Also, /model now reports if saving the default model fails, instead of falsely claiming success.
• Syntax highlighting – Fixed a bug that occasionally dropped a character after Ruby ?, Erlang $, or Perl $ sigils in permission prompts.
• Terminal UI – Fullscreen transcript no longer jumps a row when suggestion lists open/close. Two-key shortcuts now wait up to 3 seconds for the second key (important in tmux) and show a notice on timeout.
• Security – Plugins with backslashes in paths no longer bypass symlink containment checks on macOS/Linux. Plugin dirs starting with two dots are now handled correctly.
• Remote Control & background sessions – End-of-turn signal is now sent after the final message. Background (--bg) sessions are less likely to be retired mid-turn near idle timeout.
• IDE/SDK sessions – VS Code and SDK sessions no longer require re-login when a session closed during a token refresh.
• Plugin and marketplace – /plugin Discover/Browse and claude plugin list --json --available now show descriptions for marketplace plugins whose metadata only exists in plugin.json.
• Workflow runs – Resuming after a container restart now gives a clear error if the run journal is missing, instead of rerunning every agent.
• API skills – The claude-api skill's error-code guide now correctly states model access failures return 404 and unavailable beta headers return 400 (not 403).
• Non-interactive sessions – A cd now persists across turns in -p mode with stream-json input, Agent SDK, and cloud sessions.

This release focuses on hardening the developer experience, especially for teams relying on prompt caching and long-running sessions.
