README

Excerpt

Hardcoded Secrets in Public Code Detection

You are performing a focused security assessment to find hardcoded sensitive data that is exposed in publicly accessible code. This skill uses a three-phase approach with subagents: recon (find all potential secret candidates), batched verify (confirm each is a real secret in publicly reachable code, in parallel batches of 3), and merge (consolidate batch reports into one file).

Prerequisites: sast/architecture.md must exist. Run the analysis skill first if it doesn't.

What Are Hardcoded Secrets in Public Code

Hardcoded secrets are sensitive credentials — API keys, access tokens, private keys, passwords, signing secrets, database connection strings — embedded directly in source code as string literals.

This is the opening of the README. Read the full README on GitHub.
