# Trail of Bits Security Skills

Security-focused static analysis and code auditing toolkit from Trail of Bits.

## Available Sub-Skills

| Skill | File | Use When |
|-------|------|----------|
| CodeQL Analysis | [codeql-SKILL.md](codeql-SKILL.md) | Deep interprocedural taint tracking, data flow analysis |
| Semgrep Scanning | [semgrep-SKILL.md](semgrep-SKILL.md) | Fast pattern-based security scanning with parallel execution |
| SARIF Parsing | [sarif-parsing-SKILL.md](sarif-parsing-SKILL.md) | Processing and aggregating static analysis results |

## When to Use

- **Security audit** of a codebase -> Start with Semgrep for speed, then CodeQL for depth
- **Quick vulnerability scan** -> Semgrep with "important only" mode
- **Deep data flow analysis** -> CodeQL with custom data extensions
- **Processing scan results** -> SARIF parsing for aggregation, deduplication, CI/CD integration

## Workflow

1. Run Semgrep for fast initial scan (pattern-based)
2. Run CodeQL for deep interprocedural analysis (data flow + taint tracking)
3. Use SARIF parsing to aggregate, deduplicate, and prioritize findings
4. Review and triage results by severity
