Acceptance Criteria: Define

Step 0: Check for Context

If no request or task description was provided as context (the skill was invoked with no arguments and nothing in the conversation describes a feature, task, or plan to evaluate):

• Output: "This skill needs a request or task description as context. Please describe the feature or task you want acceptance criteria for, or point me to a plan file."
• STOP — do not continue.

Step 1: Identify the Plan File (if any)

Check whether the context references an implementation plan file:

• Look for a file path ending in .md mentioned in the request or conversation (e.g., .agents/plans/feature-name.md)
• Look for any .agents/plans/*.md file that matches the feature being discussed
