What problem does it solve? Applying the same compliance fix or mechanical rewrite across dozens of skill, phase, and agent files by hand is slow and error-prone. This Skill automates the sweep while keeping every change behind explicit human approval, so mass edits never slip through unreviewed. ## Core Features & Use Cases - Brief-to-criteria expansion: Converts a free-form task brief into numbered, deterministic check-and-fix criteria that proposer agents apply verbatim. - Parallel proposer dispatch: Fans out haiku proposer agents in waves of up to 6, each emitting targeted before/after edits per file without writing to plugin files directly. - Two approval gates: Presents the scoped file list and the aggregated unified diff via interactive prompts; nothing is applied without explicit user approval, and the skill never commits. - Use Case: After codifying a new guideline (e.g., every gate must end with a canonical approve/reject string), run batch-fix to retroactively enforce it across every SKILL.md, phase file, and agent file in the repo. ## Quick Start Ask the AI to batch-fix every skill file so that each Phase 1.5 gate ends with the canonical approve/reject/feedback string, then approve the scope and diff when prompted.
