Agent PRD

What this skill does

Products get a PRD before anyone writes code. Agents almost never do, which is why they get rebuilt three times. This skill fixes that: it runs a structured interview and produces a single markdown document — the Agent PRD — that defines what the agent is, how it will be judged, how it loops, what it remembers, and what will break it.

The output is a document. Not code, not a scaffold, not a repo. If the user asks you to start implementing during the interview, finish the PRD first and say why.

The PRD exists to make three things true before the first commit:

1. Success is defined in terms something can check, not in terms of vibes.
2. The loop has a stop condition that is not just a step ceiling.
3. Nothing important lives only in a context window or only in a process that can die.
