What it does
Security Review is an agent skill from mohitagw15856/pm-claude-skills. Review a design, PR, or feature for security issues before it ships. Use when asked to do a security review, security-review a change/PR, or check a feature for vulnerabilities. Produces a structured review across the common risk areas (authn/authz, input handling, secrets, data exposure, dependencies), findings ranked by severity with concrete fixes, and a ship / fix-first verdict. For code and systems you own or are authorized to review.
Its SKILL.md is about 970 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Security, covering Security review, Authentication and Authorization and RBAC. The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.
When your agent uses it
- Asked to do a security review
- Security-review a change/PR
- Check a feature for vulnerabilities
Example prompts
- “/security-review”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- AuthN / AuthZ — is identity verified, and is every action authorized (incl. object-level / IDOR, privilege escalation)?
- Input handling — validation/encoding; injection (SQL/command/template), SSRF, path traversal, deserialization, XSS.
- Secrets & crypto — hard-coded secrets, key handling, weak/absent crypto, tokens in logs/URLs.
- Data exposure — over-broad responses, PII in logs/errors, missing encryption in transit/at rest, verbose errors.
- Dependencies & config — known-vuln libraries, insecure defaults, missing security headers, CORS, permissions.
- Abuse & availability — rate-limiting, resource exhaustion, business-logic abuse, missing audit logging.
What it can do on your machine
Read from SKILL.md and the folder at commit 1cbf1f0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Security Review loads about 973 tokens when it runs. Until then it costs about 115 tokens; SKILL.md has 441 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Security Review Skill
A security review is a focused pass for the ways a change could be abused — before it reaches production. This skill reviews a design, PR, or feature against the recurring risk areas, ranks findings by severity, and gives a clear verdict with concrete fixes. It's for code/systems you own or are authorized to review, and it complements (not replaces) automated scanners and a formal pentest.
Not quite this? Use
vendor-security-reviewwhen you are assessing a third-party vendor rather than your own design.
Required Inputs
Ask for these only if they aren't already provided:
- What's under review — the design/diff/feature, and what it does.
- Context — the stack, where it runs, what data/permissions it touches, who can reach it (internet-facing? authenticated?).
- Sensitivity — the assets involved (PII, credentials, money, admin capability) and the threat context.
Output Format
Security review: [change/feature]
Summary & verdict — one-line read and a call: ✅ ship / 🔁 fix-first / ⛔ block, with the gating issue(s).
Review by risk area — scan each and note findings:
- AuthN / AuthZ — is identity verified, and is every action authorized (incl. object-level / IDOR, privilege escalation)?
- Input handling — validation/encoding; injection (SQL/command/template), SSRF, path traversal, deserialization, XSS.
- Secrets & crypto — hard-coded secrets, key handling, weak/absent crypto, tokens in logs/URLs.
- Data exposure — over-broad responses, PII in logs/errors, missing encryption in transit/at rest, verbose errors.
- Dependencies & config — known-vuln libraries, insecure defaults, missing security headers, CORS, permissions.
- Abuse & availability — rate-limiting, resource exhaustion, business-logic abuse, missing audit logging.
Findings (ranked) — each with severity, where, why it's exploitable, and the fix:
| Severity | Area | Finding (how it's exploited) | Fix |
|---|---|---|---|
| 🔴 Critical/High | |||
| 🟡 Medium | |||
| 🔵 Low / hardening |
What's done well — controls already in place (so they're kept).
Follow-ups — anything needing a scanner, a pentest, or a deeper look.

Quality Checks
- Every standard risk area is considered (authz incl. IDOR, input/injection, secrets, data exposure, deps, abuse)
- Findings are ranked by severity with a concrete, actionable fix each
- Exploitability is explained — why it's a real issue in this context, not a generic warning
- A clear ship / fix-first / block verdict names the gating issues
- Existing good controls are acknowledged; deeper follow-ups (scanner/pentest) are flagged
Anti-Patterns
- Do not produce a generic checklist — tie each finding to this code/design and its exploit path
- Do not rank everything the same — separate critical from hardening nits
- Do not report an issue without a fix — give the concrete remediation
- Do not miss authorization (IDOR/privilege) — it's the most common real-world web flaw
- Do not review code you don't own or aren't authorized to assess
Based On
Secure code/design review practice (OWASP Top 10 & ASVS risk areas, severity-ranked findings, actionable remediation).
Example Trigger Phrases
- "Do a security review?"
- "Security-review a change/PR."
- "Check a feature for vulnerabilities."
