SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill automates the extraction and analysis of HTTP/HTTPS traffic captured in Charles Proxy session files (.chlsj). It helps developers quickly locate endpoints, filter by URL patterns and HTTP methods, inspect request bodies, and export results for debugging and documentation, saving hours of manual parsing.

Core Features & Use Cases

Pattern-based filtering: extract requests by URL substring
Method filtering: filter by HTTP method (GET, POST, PUT, PATCH, DELETE)
Request body inspection: view and extract request payloads
JSON export: save filtered responses for further analysis
Summary mode: overview traffic without heavy data
Pretty-printed output: readable JSON by default
CLI and Claude Code friendly: usable from terminal or Claude Code interactions

Quick Start

Usage: python3 extract_responses.py <file.chlsj> <path_pattern> [options] Examples:

Extract all /api/users responses: python3 extract_responses.py session.chlsj '/api/users'
Show POST requests to /logs with bodies: python3 extract_responses.py session.chlsj '/logs' --method POST
Save responses to a file: python3 extract_responses.py session.chlsj '/items' --output items.json
