SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Run Semgrep static analysis scans on a codebase using parallel subagents to speed up vulnerability detection and bug hunting across multi-language projects.

Core Features & Use Cases

Automatic language detection: detects languages and selects appropriate rulesets to maximize coverage.
Parallel scanning: spawns Task subagents to run scans concurrently across languages and repos.
SARIF output merging: merges results into a single SARIF file for streamlined review.
Semgrep Pro cross-file analysis (optional): leverages cross-file taint analysis when Pro is available.

Quick Start

Provide a repository path to scan to initiate a parallel Semgrep analysis.

FAQPage Schema

How do I run static analysis on a multi-language codebase?▼

Parallel Semgrep scans automate static analysis for multi-language codebases. The system detects languages automatically and selects appropriate rulesets to identify vulnerabilities and bugs across the entire repository.

Can I get SARIF output from Semgrep scans?▼

SARIF output is generated from Semgrep scans. The tool merges results from parallel subagent scans across different languages into a single SARIF file for streamlined review.

Does Semgrep support cross-file taint analysis?▼

Cross-file taint analysis is supported in Semgrep Pro. When a Pro license is available, the scanner leverages this feature to track data flow across multiple files for deeper security insights.

Do I need a Semgrep Pro license to scan for vulnerabilities?▼

A Semgrep Pro license is not required to scan for vulnerabilities. The CLI runs full ruleset or high-confidence scans automatically, but a Pro license is optional and only needed for cross-file taint analysis.

What is the best way to speed up static analysis on large repositories?▼

To speed up static analysis on large repositories, the scanner spawns parallel Task subagents to run Semgrep concurrently across different languages. This parallel scanning approach accelerates vulnerability detection significantly.
