What problem does it solve? Repositories accumulate disorganized, duplicated, or contradictory Claude Code instructions across CLAUDE.md, .claude/rules, runbooks, and generated templates, causing lost policies and bloated context. This Skill diagnoses the existing instruction architecture and proposes a modular, traceable reorganization without silently dropping any rule. ## Core Features & Use Cases - Instruction discovery and classification: Finds CLAUDE.md, .claude/rules, commands, and SKILL.md files, detects auto-generated templates, and classifies each rule by scope (global, path-specific, runbook, ADR, wiki). - Approval-gated migration: Produces a diagnostic report with a traceability matrix in .gtsi/reviews/ and applies changes only after explicit user approval, preserving security and governance policies. - Mandatory behavioral baseline: Ensures every restructured CLAUDE.md explicitly contains four working principles (think before changing, prioritize simplicity, surgical changes, verifiable results) and validates their presence. - Use Case: A team whose automation overwrites CLAUDE.md across projects uses this Skill to identify the source template, separate global rules from project-specific ones, and migrate Airflow and dbt rules into scoped .claude/rules files. ## Quick Start Ask the assistant to review and reorganize this repository's CLAUDE.md and .claude/rules, preserving all existing policies and proposing a modular structure before applying any changes.
