SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps users understand the architecture, relationships, and gaps in local codebases by providing a comprehensive view of the code's structure and behavior.

Core Features & Use Cases

  • Comprehensive Codebase Understanding: Analyze local codebases to map architecture, relationships, real flows, contracts, and runtime contexts.
  • Search and Trace: Utilize explicit paths, directory basenames, and fuzzy matches to locate and trace code within the system.
  • Security and Safety: Ensures confidentiality of local code, logs, configs, and runtime state, summarizing only relevant information without exposing secrets.
  • Multi-Repo Analysis: Investigate relationships between multiple codebases, including imports, endpoints, and shared libraries/types/schemas.
  • Evidence Standard: Provides a clear standard for evidence, categorizing conclusions based on the strength of the supporting data.

Quick Start

Run the 'understand-system' skill to get an overview of the local codebase structure and relationships.

FAQPage Schema
How do I analyze local codebase architecture and map component relationships?▼

To analyze local codebase architecture, this tool performs deep filesystem inspection to map dependencies, internal structures, and relationships. It generates a comprehensive architectural overview revealing real flows, contracts, and runtime contexts.

Can I trace dependencies across multiple repositories and shared libraries?▼

Multi-repo dependency tracing is supported to investigate relationships between multiple codebases. It maps shared libraries, imports, endpoints, and schemas across repositories to reveal inter-system dependencies.

How does codebase mapping handle sensitive data like secrets in local configs?▼

Codebase mapping ensures the confidentiality of local code, configs, and logs by summarizing only relevant structural information. It explicitly avoids exposing secrets or sensitive runtime state during the architecture analysis.

What is the best way to locate specific code using fuzzy matches and directory basenames?▼

Locating specific code is done by utilizing explicit file paths, directory basenames, and fuzzy matches within the local system. This search and trace mechanism accurately pinpoints code components within the broader architecture.

Does system understanding provide evidence for its architectural conclusions and gap analysis?▼

System understanding provides a clear evidence standard that categorizes conclusions based on the strength of supporting data. This ensures architectural gap analysis is grounded in concrete evidence from the local filesystem.

Can I use this for multi-repo analysis without external dependencies?▼

Multi-repo analysis can be performed without external dependencies, requiring only deep filesystem inspection and access to local code repositories. It natively maps cross-repo imports and shared schemas.
