Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/owasp/secure-agent-playbook --skill code-review-security- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads code-review-security automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
Security Code Review
Review code for security vulnerabilities by following the full procedure in plays/code-review-security.md.
Steps
-
Scope & Context — Establish language/framework, trust boundary (server/client/library/CLI), data sensitivity (PII, credentials, financial), and exposure (internet-facing, internal, local).
-
Systematic Review by Vulnerability Class (priority order):
- Injection (A03) — SQL, command, XSS, SSTI, LDAP, path traversal, header, log injection
- Authentication & Session (A07) — Hardcoded credentials, missing auth, weak sessions, JWT issues
- Authorization (A01) — Missing authz checks, IDOR, horizontal/vertical privilege escalation
- Cryptography (A02) — Weak algorithms, hardcoded keys, missing encryption, custom crypto
- Data Exposure (A01) — Sensitive data in errors/logs, credentials in code, debug mode
- Misconfiguration (A05) — Default credentials, permissive CORS, missing security headers
- Deserialization (A08) — Untrusted deserialization, missing integrity checks, CSRF gaps
-
Framework-Specific Checks — Apply checks for detected framework (React, Express, Django, Flask, Spring, Rails, Go).
-
Diff-Specific Analysis (for PRs) — Focus on changed lines plus context, verify security controls preserved, check new endpoints match auth patterns, look for removed security controls.
-
Produce Findings — Cite file:line, show vulnerable snippet, explain attack scenario, provide fixed code, rate confidence.
Output
Scope summary, findings sorted by severity using templates/finding.md, positive observations (good security controls in place), and severity count table.
