SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides rapid, intelligent codebase exploration, saving you hours of manual digging. Whether you're onboarding to a new project, searching for a specific feature, or understanding architectural patterns, it quickly surfaces the information you need, reducing cognitive load and accelerating your understanding.

Core Features & Use Cases

  • File & Pattern Discovery: Quickly find files by name, extension, or complex glob patterns (e.g., **/*.rs for Rust source files).
  • Advanced Code Search: Perform exact, pattern, or context-aware searches for keywords, functions, or error handling patterns across your codebase.
  • Structure & Entry Point Analysis: Understand project organization, module boundaries, and main entry points without extensive manual navigation.
  • Use Case: Quickly get up to speed on an unfamiliar codebase by identifying key files, understanding project organization, and locating specific feature implementations without manual digging.

Quick Start

Find all Rust source files in the project.

glob '**/*.rs'

Search for all files containing "UserRepository" (case-insensitive).

grep -i "UserRepository" --output-mode files_with_matches
