What is the primary purpose of the Skill Builder?

Skill Builder acts as a router that determines whether to codify existing documentation (via Skill_Seekers) or author a new capability from scratch (via skill-creator).

Can I export these skills to other AI platforms?

Yes, Skill Builder supports a --target flag to package skills for Google Gemini, OpenAI ChatGPT, or generic Markdown formats.

Does it support deep code analysis?

Yes, when analyzing GitHub repositories, it uses AST parsing for languages like Python, TypeScript, and Go to accurately extract APIs and detect conflicts.

What is the difference between a Leaf, Hub, and Router skill?

Leaves are standalone (<300 lines), Hubs cross-reference peers (300-500 lines), and Routers are high-level dispatchers that manage multiple sub-skills.

How does the security audit process work?

It uses three sequential scanners: a structural decompiler for risk scoring, a semantic agent-based scan for malicious patterns, and the AgentShield CLI for overpermissive configs.

Developer Tools

Orchestrates the end-to-end lifecycle of AI capabilities by routing between documentation codification and manual skill authoring.

Skill Builder serves as the central nervous system for developing Claude Code skills. It provides a unified workflow for transforming external sources—including documentation websites, GitHub repositories with AST parsing, and PDF manuals—into structured AI skills. Beyond simple extraction, it manages the entire development pipeline: performing multi-stage security audits, enforcing quality scoring gates, and handling the organic growth of skills from standalone leaves to complex routers. It ensures that every skill added to your environment is secure, actionable, and formatted for maximum performance across Claude, Gemini, and OpenAI platforms.

Key Features

01Intelligent lifecycle management for Leaf, Hub, and Router skill patterns
