codebase-scan

# Codebase Scan ## Purpose / When to Activate Activate: - During Bootstrap initialization (before architecture extraction) - When onboarding GAAI onto an existing codebase - When the project structure is unknown --- ## Process 1. Recursively list directories and files 2. Identify entry points, config files, manifests, and core modules 3. Highlight likely architecture boundaries 4. Output a structured project tree and key file list --- ## Outputs **`codebase_tree`** — structured directory tree with annotations for key files **`key_files_list`** — list of significant files: entry points, configs, manifests, core modules, test runners --- ## Quality Checks - Repository structure is fully visible - Core technical pillars are identified - No blind spots remain - Output is structured for use by `architecture-extract` --- ## Non-Goals This skill must NOT: - Interpret architecture decisions (use `architecture-extract`) - Read file contents in depth - Make recommendations **Maps the terrain. Does not interpret it.**
