What problem does it solve?
It solves the maintenance and clarity problem of a single monolithic CLAUDE instruction file becoming too long, hard to navigate, and prone to contradictory rules.
Core Features & Use Cases
- Splitting strategy with precedence: Defines a safe order for how rules across multiple files should override each other to prevent conflicting behavior.
- Right moment to split: Recommends splitting only when the instruction set grows beyond practical limits (e.g., around 300 lines) or when multiple teams/concerns need different guidance.
- Organized folder patterns: Provides concrete layouts for splitting by concern, module, or team using a root index and additional topic files.
- Use-case example: When you have a growing codebase like a .NET solution and your CLAUDE guidance spans architecture, testing, data access, and deployment, you can split instructions so each topic lives near its domain and remains easy to find.
Quick Start
Ask the AI to reorganize your CLAUDE instructions by concern or module, create a root index, and apply the stated precedence rules to ensure there are no contradictory instructions across files.
