Arch Plan — Development skill for Claude Code

Create a structured implementation plan for the requested feature or change.

Steps

1. Requirements Analysis

• Clarify the goal: what problem does this solve and for whom?
• List functional requirements (what the system must do).
• List non-functional requirements (performance, security, scalability).
• Identify constraints (timeline, tech stack, backward compatibility).

2. Architecture Review

• Read the existing codebase structure to understand current patterns.
• Identify which mo
