 "problem": "Agents start coding from a vague plan and the wrong design only shows up after many files change.",
 "outcome": "A sequence or flow diagram of the planned change that you read, correct and approve before any code is written.",
 "steps": [
  "Install the skill with: npx skills add cathrynlavery/diagram-design",
  "Describe the feature, for example: Give me a sequence of a bearer call with token refresh on 401.",
  "Read the diagram and fix any wrong step by telling the agent what to change.",
  "Once the diagram matches your intent, ask the agent to implement it."

 "difficulty": "Intermediate",
 "time": "30 minutes",
