Turn any codebase into an interactive architecture map.
Analyze modules, dependencies, and data flow in seconds with a polished canvas UI.

archmap-plugin is a Claude Code plugin that generates:

• docs/architecture.html - interactive architecture graph
• docs/architecture-map.md - versionable architecture documentation

It is built for real code navigation, not static diagrams. You can pan, zoom, inspect modules, trace edges, switch themes, and export docs directly from the UI.

claude plugin install /path/to/archmap-plugin --scope user

Local test mode:

claude --plugin-dir /path/to/archmap-plugin

/archmap
/archmap <path>
/archmap --refresh

• Deep project exploration with a dedicated plugin subagent (archmap:archmap-explorer)
• Module nodes with file size, role, key types, key functions, and internal imports
• Dependency edge graph with layer/tier-aware layout
• Data flow pipeline sidebar for input-to-output reasoning
• Built-in theme switcher: Dark, Light, Claude, OpenAI
• Self-contained HTML output (no CDN, no runtime dependencies)
• Automatic Markdown export for documentation and PR reviews

1. Run /archmap at repo root.
2. Review docs/architecture.html and inspect hotspots.
3. Commit docs/architecture-map.md alongside code changes to keep architecture docs current.
