Check

Read-only verification of the agent's current work against a specific question. Produces a verdict-first answer backed by evidence from git state and codebase context.

Write and Edit are intentionally excluded from allowed-tools. This skill MUST NOT modify any files.

Workflow

Follow all 4 steps sequentially.

Step 1: Parse the Question

1. Extract the question text from everything after /check.

   • /check does the new endpoint handle errors? -> question is "does the new endpoint handle errors?"
   • /check (bare, no argument) -> must clarify

2. Classify the question:

   • Verification -- expects YES / NO / PARTIAL (e.g., "is X done?", "does Y handle Z?", "are tests passing?")
   • Explanation -- expects a short description (e.g., "what changed in auth?", "how does the new caching work?")
