legacy-code-discovery

Plans and runs a multi-phase, evidence-graded discovery program for an unfamiliar or legacy estate before a migration, replatform, rewrite, or major upgrade. Use when asked to produce a discovery dossier, estimate migration scope across a whole system, or coordinate reconnaissance, mapping, and risk/seam analysis over multiple sessions. Orchestrates repo-reconnaissance, system-cartography, and migration-seams and writes an OKF v0.2 knowledge bundle. Not for single-file changes, greenfield work, routine code navigation, or routine API documentation.

Compatibility

Requires read access to the target repositories and write access only to the discovery bundle. Works best with repo-reconnaissance, system-cartography, and migration-seams from the same plugin; the fallback in Related skills applies when they are unavailable.
