Use to reverse-engineer an existing/brownfield codebase into structured, confidence-scored characterization artifacts (tech stack, feature inventory, dependency & integration map, existing API contracts, test-coverage traceability, tech debt & risks). Use before composing a PRD, or standalone to understand a legacy system with no docs. Activate on 'characterize this codebase', 'what does this system do', 'map the architecture', 'find existing contracts', 'assess tech debt', 'reverse-engineer…
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
# Characterize Brownfield Reverse-engineers an existing codebase into structured, confidence-scored artifacts. Every claim is either a FACT (from a tool call — S7) or an INFERENCE (LLM interpretation), and every inference carries a confidence: **High** (directly observed, e.g. a parsed OpenAPI file) / **Medium** (inferred from strong signals, e.g. route patterns + naming conventions) / **Low** (guessed from weak or absent evidence). Honesty about confidence is the point — a brownfield PRD built on fabricated certainty is worse than one that says "unknown." **Boundary.** Read-only. Never edits code. Does not write a PRD (see `compose-brownfield-prd`). Does not create issues or stories. ## Inputs - Repository path (required). - Depth: `quick` (2-5 min, pattern-based, no source reads) / `deep` (10-30 min, critical dirs — **default**) / `exhaustive` (30-120 min, all source, opt-in only — warn the user of cost first). - Focus directories (optional) — narrows deep/exhaustive scans. ## Procedure ### 1. Structure & stack (FACT, via tool calls — S7 only, never recall) - `find . -maxdepth 3 -type d` (or workspace tools) for top-level layout. …

How to install
mdr add sebastiendegodez/skraft-plugin/characterize-brownfield@sha256:fdd80b8946722e92The line at the top of this page pins the label git:20260925.778348a, 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.
