Constraint Discovery is a high-performance analysis skill for Claude Code designed to identify the 'degrees of freedom' and hidden boundaries within a codebase. By deploying five specialized Explore agents in parallel, it recursively scans project memory files, architectural patterns, historical research logs, testing gaps, and configuration limits. This skill is essential for ensuring that AI-driven development remains within project-defined parameters, preventing architectural regressions, violations of established philosophy, or the repetition of past experimental failures. It centralizes all findings into a standardized JSONL format, providing a comprehensive safety map for autonomous workflows.
