audit-code -- Project Code Security Review

Security-focused code review of project source code. Covers OWASP-style vulnerabilities, hardcoded secrets, dangerous function calls, and patterns relevant to AI-assisted development.

What to do

Run the auditor against the target path:

python3 "$SKILL_DIR/scripts/audit_code.py" "$ARGUMENTS"

If $ARGUMENTS is empty, default to $PROJECT_ROOT.

What it checks

Hardcoded secrets -- API keys (AWS, GitHub, Stripe, OpenAI, Slack), tokens, private keys, connection strings, passwords

Dangerous function calls -- eval, exec, subprocess with shell=True, child_process.exec, pickle deserialization, system(), gets(), etc.

SQL injection -- String concatenation/interpolation in SQL queries

Dependency risks -- Known hallucinated package names, unverified installations

Sensitive files -- .env files committed to git, credential files in repo

File permissions -- Overly permissive chmod patterns

Exfiltration patterns -- Base64 encode + network send, DNS exfiltration, credential file reads

Output

Structured report with severity-ranked findings, file locations, and actionable remediation steps.

When to use

Before committing or pushing code

When reviewing third-party contributions or PRs

As part of a periodic security audit of the codebase

After AI-assisted code generation to verify no secrets or vulnerabilities were introduced

Advisory hooks

The repository's .claude/settings.json includes PreToolUse hooks that warn on dangerous Bash and Write operations. These hooks are advisory only -- they produce warnings but do not block execution.

audit-code is the detection layer for source code security issues

The hooks provide supplementary runtime warnings during agent operation

To enforce blocking, hooks must return {"decision": "block"}

instead of warning messages
