Onboard to an unfamiliar codebase by mapping its architecture, entry points, and data flow. Use when starting work in a new or unknown repository and you need a navigable mental model fast.
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
Build a navigable map of this repository so the reader can find their way around and start contributing. Work from evidence in the repo, not assumptions about the stack. ## Orient first - Identify the project type and stack from manifests and config (e.g. `package.json`, `pyproject.toml`, `go.mod`, `Cargo.toml`, `pom.xml`, `Gemfile`, Dockerfiles, CI config). Note the build, test, and run commands. - Read the README, docs, and any `CONTRIBUTING` or architecture notes before reading code, but verify their claims against the tree rather than trusting them blindly. - Get the shape of the tree: the top-level directories and what each is responsible for. ## Map the architecture - Find the **entry points**: CLI mains, server bootstraps, route registrations, scheduled jobs, queue consumers, lambda/handler exports, UI roots. List them with `file:line`. - Identify the **layers / modules** and how they depend on each other (e.g. interface → service/domain → data access → external integrations). Note the boundaries that matter. - Locate cross-cutting concerns: config/env loading, auth, logging, error handling, database/connection setup, feature flags. ## Trace the data flow …

How to install
mdr add khaledsaeed18/dotclaude/explain-codebase@sha256:d73aa1d88b85b238The line at the top of this page pins the label git:20260608.0cc2133, 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.
