SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires curl, jq, base64, and includes scripts (resource) components.

What problem does it solve?

This Skill provides a structured, tiered approach to researching codebases, libraries, and APIs by combining fast local exploration with lightweight web-based research, enabling faster comprehension of unfamiliar code patterns and debugging contexts.

Core Features & Use Cases

  • Tiered escalation: start with Local codebase exploration using Grep, Glob, and Read, then move to CLI tools (rg, fd, curl), web research (WebSearch/WebFetch), and lightweight API scripts.
  • Library/API research and debugging: quickly understand API usage, external dependencies, and common integration patterns across large repositories.
  • Use Case: when investigating a legacy project, locate usage of a deprecated API, verify compatibility with a target library version, and surface relevant docs and examples.

Quick Start

Analyze the current project by performing local exploration (Grep/Glob/Read) and, if needed, fetch library/API references with WebFetch or the provided scripts.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
What is the best way to research unfamiliar code and APIs?▼

Researching unfamiliar codebases is best handled by a tiered escalation strategy, starting with local exploration using Grep and Glob, then advancing to CLI tools and web research for API references and examples.

How do I investigate deprecated API usage in a legacy codebase?▼

Investigating deprecated API usage in a legacy codebase starts with local Grep searches to locate patterns, then escalates to fetching library documentation and compatibility references via WebFetch or lightweight scripts.

Do I need curl and jq installed to research external libraries?▼

Yes, researching external libraries and APIs through lightweight scripts requires curl and jq installed, as these CLI tools handle fetching and parsing JSON responses from external dependencies during the escalation process.

How does tiered code research maximize context efficiency?▼

Tiered code research maximizes context efficiency by enforcing a simple-to-advanced workflow that begins with fast local tools, escalating to CLI utilities, web research, and MCP servers only as needed.

Can I use this approach to debug unfamiliar code patterns in large repositories?▼

Yes, you can debug unfamiliar code patterns in large repositories using this structured approach, which combines local codebase exploration with web research to quickly understand external dependencies and integration patterns.
