Analyze a codebase and generate onboarding documentation for engineers, tech leads, and contractors. This skill is optimized for fast fact-gathering and repeatable onboarding outputs.
Core Capabilities
Architecture and stack discovery from repository signals
Key file and config inventory for new contributors
Local setup and common-task guidance generation
Audience-aware documentation framing
Debugging and contribution checklist scaffolding
When to Use
Onboarding a new team member or contractor
Rebuilding stale project docs after large refactors
Preparing internal handoff documentation
Creating a standardized onboarding packet for services
Quick Start
# 1) Gather codebase facts
python3 scripts/codebase_analyzer.py /path/to/repo
# 2) Export machine-readable output
python3 scripts/codebase_analyzer.py /path/to/repo --json
# 3) Use the template to draft onboarding docs
# See references/onboarding-template.md
Recommended Workflow
Run scripts/codebase_analyzer.py against the target repository.
Writing docs without validating setup commands on a clean environment
Mixing architecture deep-dives into contractor-oriented docs
Omitting troubleshooting and verification steps
Letting onboarding docs drift from current repo state
Best Practices
Keep setup instructions executable and time-bounded.
Document the "why" for key architectural decisions.
Update docs in the same PR as behavior changes.
Treat onboarding docs as living operational assets, not one-time deliverables.
