ac-init

To generate CLAUDE.md context documentation, run the /ac-init command with an optional project description. It scans the project structure, module responsibilities, key files, and dependencies to produce root-level and module-level documentation artifacts.

Automated project structure scanning works by using the Claude main thread to pull project information and optional subagents to perform read-only scans. This parallel scanning collects module responsibilities, key files, and dependency relationships to compile comprehensive context files.

You need the --modules flag when generating module-level CLAUDE.md files for multi-module repositories. It organizes module structures and interface relationships, creating specific documentation artifacts alongside the root-level context file.

Yes, the project structure scanner enforces ignore rules to automatically skip build and cache directories. This ensures the generated CLAUDE.md context documentation only includes relevant source files and module structures.

Yes, you can use subagents to scan large project structures in parallel. The main thread decides whether to enable subagents, which perform read-only scans to collect module responsibilities and dependency relationships for comprehensive documentation.

The best way to document module responsibilities is using automated scanning to identify project structure and generate CLAUDE.md context files. It captures module responsibilities, key files, and dependencies, providing a clear overview for multi-module repositories.
