Claude Code mod

read-guard

Holds a whole-file Read (no offset/limit) of a file above the limit, a lockfile, minified code or a source map, and the same via cat, type or Get-Content in the shell; tells Claude the size, a token estimate and a better way (Grep, offset/limit). A second try at the same file goes through, and so does a Read with allow_large. Claude Code itself stops only at about 25,000 tokens.

How Claude Code mods work

  • A mod is a plugin with a JavaScript or TypeScript module that runs inside Claude Code (version 2.1.287 or later). It can draw panes beside the transcript, a band above the prompt, buttons and toasts, restyle the spinner and tool rows, and watch or rewrite tool calls and prompts.
  • It installs like any plugin: add its marketplace with /plugin marketplace add owner/repo, then /plugin install name@marketplace.
  • Check what a mod can reach before installing: it runs with your permissions. Reach goes from drawing only, to reading files, to writing files or running processes, to the network. Run claude plugin validate on a clone to list its hooks and calls without running it.
  • Turn one off from the Installed tab in /plugin, or start Claude Code with --safe-mode to skip every customization for a session.
