Claude Code 2.1.287 ships Mods for in-session TypeScript extensions
Claude Code 2.1.287 turns on Mods by default: small JS/TS plugins that hook tool calls, prompts, and UI so you can rewrite behavior or draw custom panes—Anthropic already uses them for /diff and AGENTS.md. Install via /plugin; they run with full machine access, so only load mods you trust.
