Build a persistent, evidence-based map of a software repository inside docs/codebase-map/ - TL;DR, architecture and dependency diagrams in Mermaid, real data flows traced with an archetype-specific strategy, the most important files ("the spine"), a reading order, potentially AI-assisted code, key concepts, and open questions. Five modes - "codebase-map init" builds the full map, "codebase-map update" refreshes it after changes, "codebase-map explain [topic]" covers one feature or domain…
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
# Codebase Map ## Purpose Build a persistent, evidence-based mental model of a software repository. The goal is not merely to document the codebase. The goal is to help the developer understand: * how the system is structured * where important logic lives * how components depend on each other * how real user requests move through the system * which files are worth reading first * which concepts are central to the application * where AI-assisted or unfamiliar code may require additional attention * what is still unknown The output must remain inside the repository so it can be reused by the developer and future coding agents. --- # Commands The skill supports five modes. Accept them as commands, as natural language, or as a mix of both — `codebase-map update`, `/codebase-map update`, and "update the codebase map" all mean the same thing. Resolve the mode before doing any work. When the mode is ambiguous, apply the default resolution rules below rather than asking, unless the choice would waste significant effort. | Command | Mode | What it does | | --- | --- | --- | | `codebase-map` or `codebase-map init` | INIT | Full workflow. Build the complete map from scratch. | …

How to install
mdr add rdilruba/codebase-map/codebase-map@sha256:f89e1f05cd74281eThe line at the top of this page pins the label git:20260911.c64e91f, 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.
