Project Metadata Builder

Project Metadata Builder

Build comprehensive project metadata and maintain a global registry at ${CLAUDE_PROJECTS_YML_PATH}.

Activation Triggers

• After project-analysis agent completes analysis
• User says: "update project metadata", "refresh projects", "register project"
• Session start with auto_update_on_session: true in config

Execution

Run the builder script for a project:

cd ${CLAUDE_SKILLS_PATH}/project-metadata-builder && \
uv run python -m scripts.builder <project_path> [--session-id <id>]

Arguments

Output

Updates ${CLAUDE_PROJECTS_YML_PATH} with:

• Identity: Name, slug, description
• Git: Remote URL, branch, last commit (hash, message, author, date), total commits
• Languages: Primary language, all languages with percentages
• Frameworks: Detected frameworks (react, docker, playwright, etc.)
• Dependencies: Python (from pyproject.toml) and Node (from package.json)
• Structure: Project type, key directories, entry points
• Runtime: Docker services, MCP servers
• Activity: Status (active/stale/archived), timestamps
• Sessions: Last N sessions with commits and files changed

Configuration

Settings in ${CLAUDE_PATH}/config.yml (project root):

project_metadata:
  session_history_limit: 10      # Keep last N sessions
  auto_update_on_session: true   # Auto-update on session start
  periodic_refresh_hours: 24     # Periodic refresh (0 = disabled)
  stale_project_days: 30         # Mark stale after N days inactive
  activity_threshold_commits: 5  # Min commits for "active" status
  projects_file: ${CLAUDE_PROJECTS_YML_PATH}
  log_level: INFO
