codebase-recon

# 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. | Control | Values | Use when | |---|---|---| | **Mode** | `baseline` \| `delta` | First pack vs refresh after a prior recon | | **View emphasis** | mental model · bounded audit · pattern evidence · synthesis | Archaeology-style map, audit-style findings, pattern harvest, or executive synthesis | | **Lens** | persistence · auth · CLI · build · test (one per pass) | Domain-deep cut instead of a shallow whole-tree sweep | | **Depth** | quick · standard · deep | Orientation vs onboarding vs decision-grade evidence | Ask for the shape explicitly, for example: ```text codebase-recon --mode=delta --view=audit --lens=cli --depth=standard codebase-recon baseline, mental-model view, persistence lens, deep ``` Natural-language equivalents count.
