Full Analysis
  • [INDIRECT_PROMPT_INJECTION]: The skill performs automated analysis of arbitrary codebases, which involves processing untrusted external data that could contain malicious instructions.
  • Ingestion points: The skill reads source files, dependency manifests (e.g., package.json, Gemfile), and configuration files (e.g., .env.example) using tools like read_file, grep, and glob as defined in SKILL.md and sub-agent playbooks.
  • Boundary markers: There are no explicit instructions or delimiters provided to the sub-agents to isolate potentially malicious prompts embedded in the codebase from the documentation task.
  • Capability inventory: The sub-agents can read project files and write documentation to the .claude/onboarding/ directory. The coordinator has the capability to spawn and manage multiple sub-agents.
  • Sanitization: No explicit sanitization or filtering of codebase content is mentioned before it is processed or included in the generated documents.
  • [COMMAND_EXECUTION]: The skill uses local filesystem exploration tools to understand the project structure.
  • Evidence: The sub-agent playbooks (e.g., structure-guide.md) recommend using shell commands such as 'find' to map the directory tree and 'grep' to identify specific code patterns like React Server Components usage.
