PRD Authoring

Turn a feature request into an approved PRD with verifiable acceptance criteria. The full process is defined in .ai-rules/rules/02-prd.md — this skill is the trigger shape and the gate enforcer. Read that rule first.

When this skill should fire

• Human asks to "plan a feature", "write a PRD", "spec this out", "draft requirements", or similar.
• Human pastes a bug report, feature idea, or product brief that needs structured decomposition before implementation begins.
• An existing PRD needs sharpened acceptance criteria.

Do not fire for: implementation requests, refactors, code review, or work where a human-approved PRD already exists.

Required behavior

Follow .ai-rules/rules/02-prd.md exactly. The short version:

1. Explore the codebase first. Produce a written Codebase Analysis.
2. Present the analysis. Wait for the human to confirm it before continuing.
3. Ask 3–8 clarifying questions with lettered options.
4. Generate the PRD.
5. Present acceptance criteria separately. Wait for human approval.
6. Stop. Do not generate tasks or write implementation code.

Progressive disclosure

Load these references only when you need them:

• references/codebase-analysis.md — rubric, common failure modes, and a worked example for the Codebase Analysis artifact. Load when producing step 1.
• references/acceptance-criteria.md — rubric, common failure modes, and a worked example for verifiable acceptance criteria. Load when drafting step 5 or when sharpening vague human-supplied criteria.

The rule file is the source of truth for the process. References here exist for taste and calibration; they do not duplicate the rule body.

Hard gates

These gates are non-negotiable. Stop and prompt the human at each one:

• Codebase Analysis gate — do not propose a solution before the human confirms your reading of the codebase.
• Acceptance Criteria gate — do not proceed past the PRD until the human explicitly approves the acceptance criteria.

If the human asks you to skip a gate, refuse and explain why. The whole point of this skill is to preserve the human gates that the conversational flow would otherwise erode.

Out of scope

• Task generation. After AC approval, hand off to a task-breakdown skill or equivalent in your runner. This skill ends at "AC approved".
• Implementation. Never edit production code under this skill.
