Exploration Skill

Exploration Protocol

Run these 5 phases in order — full commands in references/exploration-protocol.md:

1. Initial Reconnaissance — list root files, find config files, check common entry points
2. Structure Mapping — tree view (excluding noise dirs), identify main directories
3. Entry Points Detection — grep for main/index/server bootstrap per language
4. Dependency Analysis — read package.json/pyproject.toml/go.mod/Cargo.toml/composer.json
5. Pattern Detection — check for MVC, Clean/Hexagonal, feature-based, Next.js App Router directories

Architecture Pattern Detection

Pattern Indicators

Pattern	Key Directories	Indicators
MVC	controllers/, models/, views/	Rails, Laravel, Express
Clean Architecture	domain/, application/, infrastructure/	DDD, Use cases
Hexagonal	adapters/, ports/, core/	Ports & adapters
Feature-based	features/[name]/	All layers per feature
Layered	presentation/, business/, data/	Traditional 3-tier
Monolith	Single src/	Mixed concerns
Microservices	Multiple services/	Separate repos/folders
Next.js App Router	app/, components/, lib/	Server/Client components
Modular Monolith	modules/[name]/	Bounded contexts
