Create AI Commands Effortlessly with Build-Feature Skill

Build-Feature Skill for AI Agent Commands

The Build-Feature Skill facilitates the creation of new commands, flags, or behaviors in a precise, methodical approach, tailored for AI coding agents such as Claude Code, Cursor, and Codex. It follows a tightly structured, test-first methodology to ensure all open decisions are resolved efficiently before implementation begins.

What this skill does

• Read Existing Features: Begin by examining the closest analogous command and its corresponding test within the codebase to serve as the foundational pattern for the new command.
• Settle Decisions: Concurrently resolve all open decisions, including command names, flags, outputs, error codes, and behaviour constraints by consulting with the owner.
• Write Behaviors: Document each behavior with a command and expected result to form the basis of actionable tests, ensuring checks could pass or fail effectively.

Who it is for

This skill is designed for developers and teams who employ AI agents in their coding practices, particularly those seeking to expand the functional scope of their software through carefully controlled command additions.

Use cases

• Add New Commands: Facilitate the addition of new commands in an existing software application by consistently following structured patterns.
• Implement Feature Flags: Simplify the process of implementing feature flags and behaviors that require straightforward decision-making and testing procedures.
• Support Development Teams: Assist development teams in maintaining consistent command structures and outputs through rigorous adherence to predefined methods.

Technical details

The Build-Feature Skill leverages AI agent libraries such as Claude Code, Cursor, and Codex to develop new command features. It focuses on pre-existing code inspection, decision resolution, and behavior documentation to establish a robust framework for command augmentation.
