Security audits are most useful when they produce an actionable, prioritised list of real risks — not a vague checklist. This pack helps Claude assess apps, review dependencies, and build threat models that devs can execute against.
What you can do with this pack
- Do a focused security review of a service or feature
- Review new dependencies for supply-chain risk
- Threat-model a new feature before building
- Audit auth and authorisation logic
- Triage a security incident quickly
Skills in this pack
App Security Auditor
Do a focused security review of a service or application. Trigger on 'security audit', 'secure this app', 'security review of', 'pentest prep', or when the user wants a defensive security assessment of an app or service.
Dependency Risk Reviewer
Assess a new or existing dependency for security and maintenance risk. Trigger on 'is this package safe', 'review this dependency', 'npm audit', 'supply chain', 'check this library', or when the user is about to add or update a third-party package.
Feature Threat Modeller
Build a threat model for a new feature before it ships. Trigger on 'threat model', 'what could go wrong', 'security design review', 'abuse cases', or when the user is planning a feature and wants to think through attacks.

FAQ
What is a Claude skill?
A Claude skill is a folder containing a SKILL.md file. It tells Claude when to trigger the skill and how to execute the task. Skills live inside your Claude account once uploaded.
Do these work on Free, Pro and Max plans?
Yes, as long as code execution is enabled. On Team and Enterprise plans, an admin needs to enable skills at the organisation level first.
Can I edit the skills?
Yes — the skills are plain markdown files. Open SKILL.md in any editor and change the description, steps, templates, or output format to match how you work.
Do I need all the skills in the pack?
No. Upload only the ones you'll use. Too many active skills makes Claude less precise about which one to pick.
