Is security checked during the development process?

Yes, Phase 6 involves a dedicated security and error handling review pass with a confidence scoring system to identify vulnerabilities.

Can I approve the design before code is written?

Absolutely. The workflow requires explicit user approval of the Implementation Blueprint and ADR before proceeding to Phase 5.

What are the 7 phases of the feature-dev skill?

The workflow includes Discovery, Codebase Exploration, Clarifying Questions, Architecture Design, Implementation, Quality Review, and Summary.

How does the three-lens analysis work?

It evaluates every design decision based on Simplicity, Extensibility, and Consistency to ensure the best trade-off for the specific project context.

Does this skill handle project documentation?

Yes, it automatically generates Architecture Decision Records (ADRs) in your repository and updates your CHANGELOG.md file.

Productivity & Workflow

Executes a structured 7-phase workflow to guide feature development from initial discovery through implementation and quality review.

This skill provides a rigorous, systematic framework for building new features or making significant changes within a codebase. It guides the AI through a comprehensive process including deep codebase exploration, three-lens architectural analysis (balancing simplicity, extensibility, and consistency), and automated documentation via Architecture Decision Records (ADRs). By enforcing a triple-pass quality review—covering correctness, security, and maintainability—it ensures that new code is robust, secure, and perfectly aligned with existing project patterns.
