A2a Code Audit

Audit Python and JavaScript code for security vulnerabilities, style issues, and bugs using static analysis tools and provide a detailed structured report.

Code Audit & Security Scan

Static code analysis for security vulnerabilities, style violations, and bugs.

When to Use

Trigger on: "audit code", "scan for bugs", "security check", "code review", "find vulnerabilities"

What This Does

• Analyzes code for common security issues
• Checks for style violations
• Identifies potential bugs
• Returns structured report with severity levels

Supported Languages

• Python
• JavaScript/TypeScript

Workflow

Step 1: Receive Code

Get code to analyze + language.

Step 2: Static Analysis

Analyze using pattern matching and heuristics:

Python checks:

• Use of eval(), exec(), import()
• Hardcoded credentials
• SQL injection risks
• Path traversal
• Insecure random

JS/TS checks:

• eval() usage
• innerHTML without sanitization
• Hardcoded API keys
• console.log in production code

Step 3: Scoring

text

Score = 100 - (issues_found × severity_weight)
Verdict: PASS (>80), WARN (50-80), FAIL (<50)

Step 4: Present Results

text

## Code Audit: [language]

### Summary
| Metric | Value |
|--------|-------|
| Score | [X]/100 |
| Verdict | [PASS/WARN/FAIL] |
| Issues | [N] |

### Issues
1. [SEVERITY] [issue description] (line [N])
2. ...

### Recommendations
- [fix suggestions]

No External Tools Required

This skill uses only:

• Platform exec tool
• Pattern matching
• No external binaries needed

Example

text

## Code Audit: Python

### Summary
| Metric | Value |
|--------|-------|
| Score | 70/100 |
| Verdict | WARN |
| Issues | 3 |

### Issues
1. HIGH: eval() usage (line 2)
2. MEDIUM: hardcoded 'password' (line 5)
3. LOW: unused import 'os' (line 1)

### Recommendations
- Replace eval() with safer alternatives
- Use environment variables for secrets
- Remove unused imports

Notes

• Works with platform tools only
• No install steps required
• Pattern-based analysis (not full compiler)
• Always note limitations in report
