Claude Code mod
witness
Keeps a ledger of what you asked for and counts it done only on evidence: claims stay pale until a read-back confirms them, bare SQL UPDATE or DELETE writes are held for your answer, and a print of what was and was not witnessed goes into the session log.
Install
/plugin marketplace add iniphi/witness
/plugin install witness@iniphi-witnessMods install like plugins. Run /reload-plugins or start a new session to load it.

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.
