security
by alinaqisecurity skill for OWASP patterns, secrets management, and security testing. Use it to review auth, user input, API keys, env vars, and repo hygiene, especially for Security Audit work.
This skill scores 78/100 and is worth listing: it gives agents a clear security-focused trigger, substantial workflow guidance, and concrete rules for handling secrets, env files, and security review tasks. Directory users can expect useful install-time leverage, though it is more of a broad security playbook than a tightly scoped, tool-backed automation skill.
- Clear triggerability via when-to-use for auth, user input, API keys, and security review requests
- Substantial operational guidance with explicit rules for .gitignore, .env.example, and security testing
- Strong agent leverage from detailed headings, constraints, and repo/file references that reduce guesswork
- No install command or supporting scripts/resources, so adoption is manual and less turnkey
- No scope summary or support files, so users must infer how far the skill goes beyond the documented best practices
Overview of security skill
What the security skill does
The security skill helps you add and review baseline protections for code that handles auth, user input, secrets, APIs, or production configuration. It is most useful when you need a security skill that turns a vague “make this safe” request into concrete checks, especially for Security Audit work.
Who should use it
Use this skill if you are shipping application code, reviewing a repo before merge, or standardizing secure defaults across a team. It is a good fit for developers who want practical security guidance without starting from scratch or guessing which files to inspect first.
What makes it useful
The skill focuses on real project safeguards: .gitignore, environment variable handling, secret exposure, and automated security testing. Its main value is that it gives you a security guide with opinionated setup steps instead of generic reminders, which helps reduce missed basics and shallow reviews.
How to Use security skill
Install and activate it
Run the security install in your Claude skills workflow, then open skills/security/SKILL.md first. Since the repo ships as a single skill file, you should expect the instruction source to be compact and self-contained rather than spread across helper folders.
Give it the right input
The security usage works best when you tell it:
- the framework or stack
- where secrets and env vars live
- whether you want a review, a hardening pass, or test coverage
- the risk area, such as auth, file upload, or public client envs
A weak prompt is: “Check this app for security.”
A stronger prompt is: “Audit this Next.js app for leaked secrets, unsafe client env vars, and missing .gitignore entries; propose fixes and tests.”
Read the right parts first
For this security skill, start with SKILL.md and the sections on core principle, required security setup, and environment variables. Those are the decision-driving parts that tell you what the skill expects before you apply it to your own repository or prompt.
Use it in a workflow
A practical workflow is: identify the risky surface, map the relevant files, ask for a focused review, then apply fixes and re-run the checks. This works better than asking for a broad “security pass” because the skill is built around concrete repo hygiene and validation steps, not abstract policy.
security skill FAQ
Is this only for Security Audit tasks?
No. The security skill is useful for everyday hardening too, especially when you are editing auth flows, storing secrets, or setting up environment files. Security Audit is a strong use case, but not the only one.
How is this different from a normal prompt?
A normal prompt often produces general advice. This security skill is more useful when you want a repeatable security guide that pushes you toward specific files, required setup, and common leak paths instead of broad best practices.
Is it beginner-friendly?
Yes, if you can describe your stack and your concern clearly. It is less helpful if you want a one-shot “fix everything” answer without context, because security decisions depend on where code runs and which values are public versus private.
When should I not use it?
Do not use it as a substitute for a dedicated compliance review, penetration test, or architecture-level threat modeling session. If you only need a tiny syntax fix with no security impact, the security skill is probably overkill.
How to Improve security skill
Give concrete threat context
The best results come when you name the asset at risk: API keys, session cookies, upload paths, database credentials, or public env vars. The security skill can then focus on the real failure mode instead of producing a generic checklist.
Share the repo shape and constraints
If you want better security usage, include the framework, deployment target, and any constraints such as “must keep client env vars public-safe” or “cannot add new dependencies.” That helps the skill avoid fixes that are correct in theory but wrong for your stack.
Ask for verification, not just advice
For Security Audit work, request specific outputs such as “list the insecure files,” “show the exact .gitignore additions,” or “flag any env vars that should not be client-exposed.” This forces actionable review behavior and makes the output easier to apply.
Iterate after the first pass
Use the first answer to identify missing controls, then ask for a narrower follow-up: secrets handling, dependency checks, or auth boundary review. The skill improves when you feed it concrete findings, because the next pass can be targeted instead of repeating the same security basics.
