File

Category: General · Sub-category: general-misc · Last updated: 2026-05-08

Invoke this skill (or /rulesense:file) when a user wants to format, clean up, or make their Claude Code rules more readable. Trigger phrases include "lint my rules", "format my rules", "clean up my rules", "make my rules more readable", "fix my rule formatting", "tidy my rules". Also triggers on scoped variants: "lint the rules for this folder", "format rules in src/", "clean up rules under api/". This skill applies three structural transforms only — it never rewrites rule content, adds examples, or scores rules (those belong to assay and forge). Produces a before/after diff for user confirmation before writing.

From the source SKILL.md

Reformat Claude Code rule files using three structural transforms: split multi-concept bullets into one-concept-per-bullet, add blank-line separation between bullets, and restructure long single-directive rules into sub-lists.
