metronome
A Claude Code plugin that prevents Claude from taking shortcuts on repetitive tasks.
Problem
When Claude encounters repetitive tasks, it tends to declare "I'll work efficiently" and then:
- Switches from step-by-step edits to bulk operations (e.g.
sedone-liners) - Breaks files, then runs
git checkoutto revert—losing unrelated uncommitted changes too
Example: Asked to fix comments across 20 files one by one, Claude processes 5 files correctly, then announces "I'll handle the rest efficiently." It runs a sed command that corrupts files, notices the breakage, and runs git checkout to undo everything—including your other uncommitted changes.
This plugin detects such declarations and blocks the Bash tool call, reminding Claude to slow down.
