How does the three-phase process work?

The skill follows a sequence: Phase 1 maps the system components, Phase 2 extracts global rules and invariants, and Phase 3 creates detailed profiles (dossiers) for each specific component.

Can I run specific phases individually?

Yes, you can use arguments like 'map', 'invariants', or 'dossiers' to trigger a specific phase of the investigation independently.

What kind of 'invariants' does this skill identify?

It extracts rules across 8 categories including Security, Data Ownership, API Contracts, Idempotency, and Failure Modes to ensure system integrity.

Does it support large repositories?

Yes, it is designed for quality by investigating one item or component at a time and tracking progress via YAML files to handle large-scale systems incrementally.

Where is the architectural data stored?

The skill generates structured YAML files directly within your repository in the system-map/ and component-dossiers/ directories for version-controlled documentation.

Analyzes codebases to generate structured system maps, architectural invariants, and detailed component documentation in YAML format.

This skill provides a structured framework for reverse-engineering and documenting complex codebases through a three-phase approach. It begins by mapping core system components and boundaries, progresses to extracting global architectural invariants (such as security rules and data ownership), and concludes by creating deep-dive dossiers for individual modules. By transforming raw code into high-fidelity, machine-readable documentation, it helps developers maintain a consistent mental model of system-wide constraints and dependency chains.
