Claude Code mod

second-opinion

/second-opinion asks Fable (or the model you set) for a candid senior review of your recent commits, branch, uncommitted diff or a plan file, in the background without switching the session's model. Each run is one paid model call against your usage; the review opens in a pane, is saved under ~/.claude/second-opinions/, and can be handed to Claude with your next prompt.

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.
