Individual skill
sast-analysis
Perform codebase analysis and architecture mapping as the first phase of a security assessment. Explores the tech stack, frameworks, entry points, data flows, and trust boundaries. Outputs sast/architecture.md. Run this before any vulnerability detection skill. Use when asked to analyze a codebase for security or when sast/architecture.md does not yet exist.

# Codebase Analysis
You are performing the first phase of a security assessment. Your goal is to deeply understand the codebase. You are NOT looking for specific vulnerabilities yet. This is pure reconnaissance.
Create a `sast/` folder in the project root (if it doesn't already exist). This phase produces one output file inside it:
`sast/architecture.md` — technology stack, architecture, entry points, data flows
## Phase 1: Technology Reconnaissance
Explore the codebase and identify:
- **Languages**: All programming languages used and their versions if specified
- **Frameworks**: Web frameworks, ORM layers, template engines, task queues
