SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps developers understand how external libraries actually work internally when documentation, types, or public APIs are not enough.

Core Features & Use Cases

Source Retrieval: Fetches source code for npm packages, PyPI packages, crates.io packages, and GitHub repositories for deeper investigation.
Structured Research Workflow: Guides implementation analysis through identification, fetching, locating, analyzing, and documenting evidence from source files.
Use Case: When debugging an unfamiliar dependency behavior, use this Skill to inspect the package implementation, trace execution paths, and produce evidence-backed findings.

Quick Start

Use the opensrc skill to investigate the internal implementation of the zod package and summarize the relevant source code findings.

FAQPage Schema

How do I inspect the source code of an npm dependency to debug undocumented behavior?▼

To inspect npm dependency source code for undocumented behavior, you fetch the package repository, detect the specific version, navigate internal files, and collect evidence to trace execution paths. This structured research workflow analyzes the actual implementation rather than relying on public API types.

What is the best way to research a GitHub repository implementation when documentation is insufficient?▼

Researching a GitHub repository implementation requires a structured workflow of source identification, fetching, locating relevant files, and documenting technical evidence. This deep code inspection workflow evaluates packages and uncovers internal mechanics beyond insufficient documentation.

Does this source inspection approach work with PyPI and crates.io packages?▼

Yes, source inspection works with PyPI and crates.io packages. The workflow supports fetching and analyzing source code across npm, PyPI, crates.io, and GitHub repositories, enabling dependency analysis and implementation debugging across multiple software engineering ecosystems.

When do I need to analyze package source code at the implementation level?▼

You need to analyze package source code when debugging unfamiliar dependency behavior, evaluating external libraries, or investigating undocumented APIs. Implementation-level research provides evidence-backed findings by tracing execution paths directly within the source files.

How do I trace execution paths in an external library to find the root cause of a bug?▼

To trace execution paths in an external library, fetch the source code, resolve the correct repository version, locate the relevant implementation files, and analyze the code navigation flow. This source inspection produces structured technical documentation of the root cause.
