Acquire Codebase Knowledge

Drops seven markdown files in docs/codebase covering stack, structure, architecture, conventions, integrations, testing, and concerns. Runs a Python scan script first to catalog manifests, dependencies, CI configs, and metrics across 25+ languages, then populates templates based only on verifiable evidence. The workflow is rigid by design: every claim needs a file reference, unknowns get marked TODO, and you validate against checklists before finishing. Best for onboarding or legacy audits where you need grounded documentation fast. Won't guess or infer, which means you get honest gaps instead of plausible fiction. Handles monorepos and path aliases but demands Python 3.8+ and won't work without running from project root.
