description: Audit staged changes (or a specific file/directory) for security issues in three categories. Hardcoded secrets — AWS keys, `sk-`/`sk_live_`/`sk_test_` patterns, password/secret assignments, private-key blocks, `.env` contents, API tokens, JWTs, bearer tokens. OWASP top-10 — SQL injection via string concatenation, XSS via unsanitized rendering, missing permission checks, unsafe deserialization (`eval`/`exec` on untrusted data), debug-mode misconfigs, PII or tokens in logs. Dependency risks — runs `pip-audit` for Python diffs, `npm audit` for JS/TS diffs, flags new unpinned deps. Scope defaults to `git diff --cached`; falls back to the last commit if nothing's staged; an explicit path overrides. Reports findings in a severity-ranked table (CRITICAL/HIGH/MEDIUM/LOW/INFO) with file:line + recommendation per row, or a "no issues detected" verdict listing what was checked. Use before committing changes touching security-sensitive paths. Do NOT use for full-codebase audits (diff-scoped — see Claude Code's `/security-review` for branch-wide review), runtime/fuzzing analysis, or as a substitute for full-lockfile dependency scanning.

# /security-check — Audit Changes for Security Issues
Scan staged or recent changes for secrets, OWASP vulnerabilities, and dependency risks.
## Usage
```
/security-check [FILE_OR_DIRECTORY]
```
If no argument is given, audit all staged changes (`git diff --cached`). If there are no staged changes, audit the diff from the last commit.
## Instructions
1. **Gather the changes** to audit:
- Staged changes: `git diff --cached`
- Or last commit: `git diff HEAD~1`
- Or specific path if provided
2. **Check for hardcoded secrets** — scan for patterns:
- AWS access keys (`AKIA...`)
- Generic secret patterns (`sk-`, `sk_live_`, `sk_test_`)
- Password assignments (`password=`, `passwd=`, `secret=`)
- Private keys (`-----BEGIN.*PRIVATE KEY-----`)
- `.env` file contents committed by mistake
- API tokens, JWTs, or bearer tokens in source code
3. **OWASP Top 10 review**:
- SQL injection: string concatenation in queries
- XSS: unsanitized user input rendered in HTML/JSX
- Broken authentication: missing permission checks on endpoints
- Insecure deserialization: unsafe deserialization of untrusted data (e.g., eval, exec)
- Security misconfiguration: debug mode enabled in production settings
- Sensitive data exposure: PII or tokens in log statements
4. **Dependency audit**:
- Run `pip-audit` if Python files changed
- Run `npm audit` if JavaScript/TypeScript files changed
- Flag any new dependencies added without version pinning
5. **Report findings** in a table:
| Severity | File:Line | Finding | Recommendation |
|----------|-----------|---------|----------------|
Severity levels: CRITICAL, HIGH, MEDIUM, LOW, INFO
6. If no issues found, report "No security issues detected" with a summary of what was checked.
