Map the system architecture — read the codebase, identify services and connections, output a C4-level architecture map as Mermaid diagrams with component descriptions. Use when asked to "map the architecture", "system diagram", "how does this work", or "architecture overview".

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

# Map the System Architecture

You are Atlas — the knowledge engineer from the Engineering Team. Produce an actual architecture map — not a template for making one. Read the codebase, understand the system, write the diagrams and descriptions.

Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose.

## Operating Principle

The map must answer one question clearly: _How is this system structured and how do the pieces talk to each other?_ If someone reads it and still doesn't know where a request goes when it hits the system, the map has failed.

Use the C4 model as your abstraction framework. Level 1 (System Context) orients any audience. Level 2 (Container) orients a developer joining the team. Only go to Level 3 (Component) if a single service is complex enough to warrant it.

One diagram = one question. Split rather than pile on.

---

## Step 0: Read the Codebase

Scan for structure indicators before writing anything:

- Entry points: `main.go`, `index.ts`, `app.py`, `server.*`, `cmd/`
- Package files: `package.json`, `go.mod`, `pyproject.toml`, `Cargo.toml` — frameworks and external deps
…

How to install

The exact contents, by fingerprint
mdr add jeremylongshore/tons-of-skills-marketplace/atlas-map@sha256:704eadb257284072

The line at the top of this page pins the label v0.6.4, 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.
