ClaudeMap Runtime (Repo Architecture Map)

Turns any repository into a live, human-legible architecture graph and drives that map during code walkthroughs.

Dev & CodingIntermediate★ 291⑂ 16AI score 9/10Last updated: Apr 20, 2026

What it does

  • Snapshots the target project root into raw JSON via the bundled snapshot.js.
  • Hands the snapshot to the @claudemap-architect subagent, which returns a detailed graph JSON grouped into intuitive systems.
  • Renders the graph in the bundled ClaudeMap Vite UI and keeps it in sync with code changes through /refresh.
  • Supports scoped subsystem maps (/create-map), guided walkthroughs (/explain), and presentation control such as highlight/focus/flows (/show).
  • Enforces strict failure handling: if the architect pass fails, it stops instead of silently rendering a heuristic graph that would pollute the cache.

Who it's for

  • Developers inheriting an unfamiliar or legacy codebase who need the big picture fast.
  • Tech leads running onboarding sessions or architecture reviews who want a visual to point at.
  • Architects comparing system boundaries before and after a refactor.

Examples

  1. /setup-claudemap ~/work/my-api — build the map for that repo and launch the UI.
  2. /create-map just the auth subsystem — filter the root graph to auth files and get a richer internal breakdown (2–6 internal subsystems).
  3. /refresh then /explain — diff the repo, preserve untouched architect-authored scoped maps, then walk the request flow step by step on the live map.

Try it now, no install

Paste this into Claude to use the skill without installing anything.

Read the instructions in this file and follow them to help me:
https://raw.githubusercontent.com/QuinnAho/claudemap/HEAD/skill/SKILL.md

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)
  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
↓ Download ZIP
Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the skill folder from the GitHub repo QuinnAho/claudemap into my ~/.claude/skills/claudemap-runtime/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/QuinnAho/claudemap.git ~/.claude/skills/claudemap

⚠ This is a third-party skill. Check the source repository before installing.

  1. Confirm Node.js is installed (node -v); Node 18+ is recommended since the bundled UI uses Vite.
  2. Create the skills folder: mkdir -p ~/.claude/skills
  3. Clone the whole repository (not just the markdown): git clone https://github.com/QuinnAho/claudemap.git ~/.claude/skills/claudemap
    • skill/commands/*.js, skill/prompts/*, and the app/ directory are all required.
  4. Also install the packaged .claude/agents/claudemap-architect.md subagent and the .claude/commands/*.md slash commands as described in the repo README.
  5. Install dependencies: cd ~/.claude/skills/claudemap && npm install
  6. Restart Claude Code, open the project you want to analyze, and run /setup-claudemap.
  7. When the map renders, answer the follow-up prompt to request refinements instead of rebuilding from scratch.
