Characterize existing code into a rebuild package a team can reimplement from without the source: behavior specs, domain model, BR-NNN rules (explicit/implicit), quirks, gaps, entry-point completeness, each claim cited file:line with confidence. Use on "reverse-engineer this for a rebuild", "extract the business rules", "reimplement X without the original code", "characterize code for a rewrite".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# reverse-spec-for-rebuild Turn existing code into a **rebuild package**: enough data shapes, business rules, implicit behavior, provenance and known unknowns that a team can rebuild the same business logic and use cases without the original source. Works in any git repository; a kb tree and the OpenSpec CLI are optional accelerators. Not the same as a kb-oriented behavioral spec generator: those strip line numbers and rule catalogs on purpose. This skill keeps them, so its output never goes under a kb-indexed root. Methodology (provenance citations, confidence levels, state/edge/error checklists, entry-point completeness) adapted and rewritten from greenfield (Apache-2.0); see the package `NOTICE`. ## When to use - A system will be rewritten (new stack, new team, vendor exit) and its business logic must survive. - You need a catalog of business rules, including the implicit ones that live in defaults, exception handlers and ordering. - You need to know what is NOT known about a system (registered gaps). Skip for a single trivial file, or when you only want searchable docs. ## Inputs - Target directory (default: repository root) and an optional single capability. …

How to install
mdr add blackbelttechnology/pi-agent-dashboard/reverse-spec-for-rebuild@sha256:934266d37f501ab3The line at the top of this page pins the label git:20261006.3a198d2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
