What problem does it solve? Keeping a standard operating procedures repository consistent is hard: stack documents drift in structure, changelogs get forgotten, and agents generate code where only documentation belongs. This Skill gives AI agents a strict, enforceable rulebook for every modification to the SOP repository. ## Core Features & Use Cases - Mandatory Document Structure: Requires every stack document to contain Project Structure, Naming Conventions, Architectural Patterns, and Testing Strategies sections in a fixed order. - Documentation Synchronization: Keeps the active task file in tasks/, DESIGN.md, and CHANGELOG.md (Keep a Changelog format) in sync whenever system-prompt.md or structural files change. - Markdown-Only Enforcement: Restricts all output to validated Markdown documentation and prohibits generating application code inside the SOP repository. - Use Case: When an agent updates a stack rule document, it must also update CHANGELOG.md, record status and architectural reasoning in the active task file, and validate Markdown formatting before marking the task complete. ## Quick Start Apply the sop-maintenance rules whenever you modify any document in this SOP repository and update the changelog and active task file accordingly.
