Security Skills

Security work is procedural.
So ship the procedures.

Recon, exploitation, hardening, response and audit — written as reviewable SKILL.md procedures your agent loads on demand.

Build an automated, continuously-running reconnaissance pipeline for bug bounty programs — subdomain enumeration, service fingerprinting, and change detection.

Bug Bounty3 installs

04
bug-bounty-report-writing

Write bug bounty reports that get triaged quickly and rated accurately — clear impact statements, minimal reproduction steps, and professional tone.

Bug Bounty3 installs

Web App Security3 installs

Harden7close the gap
09
agentic-sdlc-controls

Review a development pipeline where AI coding agents write, commit and deploy — permission boundaries, approval gates on irreversible actions, credential scope, and what must never be delegated.

Review network segmentation designs and verify enforcement — VLANs, firewalls, cloud security groups, and zero-trust boundaries.

Network Security2 installs

14
secure-code-review

Perform a security-focused code review — map trust boundaries, audit input paths and auth flows, and use vulnerability-class-driven checklists instead of line-by-line skimming.

How it works

01

Pick a skill

Every entry is a plain SKILL.md — frontmatter plus a markdown procedure. Read it before you install it.

02

Install it

The skills CLI writes it into your agent's skills directory. One command, no repo to clone.

03

Use it

Your agent loads the skill when a task matches its description, and follows the procedure step by step.
