Vibecoding Use Cases

Overview

This repository defines USECASES.jsonc, a standardized JSONC-based format for documenting use cases in small to mid-scale vibecoding projects. Vibecoding blends AI-assisted coding (e.g., Cursor, Aider, Roo Code) with rapid iteration, typically for 1–10 developers building CLI tools, web apps, or scripts. The format offers:

• Human-readable documentation: Converts to Markdown with Mermaid diagrams for clarity.
• Programmatic access: Parseable by AI agents (e.g., for code generation) or CI/CD pipelines (e.g., test automation).
• Simplicity: Lightweight schema, editable in text editors, with comments for context.

Unlike traditional SWE frameworks (e.g., UML, Agile), USECASES.jsonc is tailored for vibecoding’s lightweight, AI-driven workflows. See COMPARISON.rst for a detailed comparison.

USECASES.jsonc Format

The USECASES.jsonc file stores use cases as a JSON array, with each use case containing:

• id: Unique identifier (e.g., "UC-VIBE-001").
• actors: Entities involved (e.g., "Developer", "AI Agent").
• description: Brief summary of the use case.
• preconditions: Conditions before execution.
• postconditions: Expected outcomes.
• basic_flow: Step-by-step interaction sequence.
• core_scenario: High-level goal.
• feature_specific_scenario: Context for specific features.
• needs: Requirements or motivations.
• choices_compromises_assumptions: Rationale for design decisions.
• solution: Expected output or behavior (e.g., command, result).
• mermaid_flow: Mermaid syntax for flow diagrams.

JSONC (JSON with Comments) ensures parseability while allowing human-readable comments. See USECASES.jsonc for an example meta-use case.

Usage

1. Create Use Cases: - Write use cases in USECASES.jsonc following the schema. - Example: Document a CLI command, web endpoint, or script behavior.
2. Convert to Documentation: - Use jsonc2md (forthcoming) to generate Markdown with Mermaid diagrams. - Example: go run jsonc2md -input USECASES.jsonc -output usecases.md
3. Generate Diagrams: - Use jsonc2mmd (forthcoming) to extract Mermaid diagrams. - Example: go run jsonc2mmd -input USECASES.jsonc -output diagrams.mmd
4. Integrate with AI/Automation: - Parse USECASES.jsonc with AI agents for code generation or analysis. - Use in CI/CD for test generation or feature validation.
