Anthropic launches Claude Code mods: TypeScript functions that rewrite prompts and UI
KhuyenTran16 · x · 2026-10-07
Anthropic has announced mods, small TypeScript functions that customize how Claude Code behaves and looks. Mods ship inside plugins and work in both the CLI and desktop app.
- What they can do: run before/after/instead of events — rewrite prompts before they reach the model, block/rewrite/retry tool calls, auto-approve or deny permission requests, redact secrets from tool output, add new UI, or replace built-in features
- Vs hooks: hooks couldn't rewrite events, draw UI, or replace features; mods can
- Design: shared publicly on GitHub before launch for developer feedback
- Security note: mods run with the same machine access as Claude Code itself, are not sandboxed, and should only be installed from trusted sources
