How long does a typical codebase exploration take?

The two-phase exploration typically takes 6-10 minutes, saving hours of potential rework caused by incorrect assumptions or incomplete context.

Can I skip discovery if I already know the codebase architecture?

No, the skill is designed to validate assumptions, as mental models are often stale or high-level. Discovery reveals recent changes and forgotten implementation details.

Why use this skill instead of just using 'grep'?

While grep finds specific strings, this skill maps the entire architectural context, preventing the need for multiple round-trips and uncovering hidden dependencies grep might miss.

When is the best time to use the Exploring Codebase skill?

It is best used when starting work on unfamiliar code, planning cross-layer changes, or when dealing with high-stakes production emergencies where accuracy is critical.

What is the 'Two-Phase' approach?

Phase 1 is a Meta-Exploration to map the structure (architecture, components, layers); Phase 2 is an Adaptive Deep Dive that targets specific areas based on Phase 1's findings.

Learning & Documentation

Automates multi-perspective discovery and deep-dive analysis to provide a comprehensive architectural understanding of any codebase.

About

This skill implements an autonomous two-phase workflow to eliminate the risks of incomplete context and stale mental models during software development. It starts by discovering natural architectural perspectives—such as layers, components, and boundaries—then dispatches adaptive parallel agents to explore each area in detail. This systematic approach is designed to prevent common engineering pitfalls like the Cascade Effect or hidden dependencies, ensuring that even under high production pressure, developers work with a complete and validated mental model of the system rather than relying on dangerous shortcuts.

Key Features

Automatic identification of architectural patterns, modules, and organization principles
Built-in Red Flag prevention system to bypass common engineering assumptions and shortcuts
Two-phase autonomous exploration: discovery pass followed by adaptive deep-dives
Synthesis of complex findings into actionable, comprehensive system insights
Parallel exploration agents tailored specifically to the discovered codebase structure
17 GitHub stars

Use Cases

Planning architectural changes or features that span multiple system layers
Onboarding or starting work on an unfamiliar codebase or legacy component
Investigating complex system behavior across microservices or library boundaries
