Codebase Recon

Build a reusable, falsifiable model of a repository. This skill reports what the tree and executable probes support; it does not edit code or issue a final PASS/WARN/FAIL verdict.

Constraints

• To prevent a floating recon, record the exact repository commit and local source-of-truth precedence.
• Because confidence is not evidence, type every material claim and cite each fact and inference.
• To preserve traceability, prefer a verified delta when a prior pack exists instead of rewriting unchanged evidence as fresh discovery.

Modes, views, and lenses

One skill replaces a cluster of loose recon skills. Steer it with mode, view emphasis, lens, and depth — do not invent a second skill for each shape.
