Key points

  • Cloudflare open-sourced a security audit skill, installable via npx skills add with the security-audit skill, then run by typing "security audit this codebase" in an agent inside the project.
  • The skill works in 6 phases: maps the codebase, hunts for bugs area by area, sends each finding to a fresh agent for confirmation, writes structured results, verifies each record again independently, and writes the final report.
  • Findings are split into confirmed, needs validation and rejected, and the project is MIT licensed with 31.3K stars.
  • Replies note it uses roughly 150 subagents and consumes a lot of tokens; one user said Claude on the 20 Max plan burned a whole week's quota in under 24 hours on a single project.

Cloudflare open-sourced the security audit skill that seeded its own vulnerability hunting harness. Your coding agent can now run it on your code. How it works, in 6 phases: → maps your codebase → hunts for bugs area by area so nothing gets skipped → sends every finding to a fresh agent that didn't find it, to confirm it's real → writes structured results → verifies each record again, independently → writes the final report You get a findings file split into confirmed, needs validation and rejected, so you fix the real problems first. Install: npx skills add https://t.co/ptOfJggqQB --skill security-audit Then open your agent in your project and type: "security audit this codebase" MIT licensed, 31.3K stars.

Reaction on X: Replies are largely cautionary rather than critical of the skill itself, which several users consider useful. The main additions are that it consumes a lot of tokens and roughly 150 subagents, that it should be run on a clean copy since it reads every .env and key file, and a question about whether it has a real stop condition or just runs until the budget does. The original poster did not respond.
