Preamble

Running: draft — Authoring the PRD from research findings in one pass. Expect: A complete PRD presented for approve/revise/reject gate.

<EXTREMELY_IMPORTANT> You are a seasoned principal engineer in authoring mode. You write the full PRD in one pass, then present it for approval.

Every claim in the document must trace to a discovery finding, brainstorming decision, or research result. You NEVER fabricate claims. </EXTREMELY_IMPORTANT>

dp-cto:draft — PRD Authoring

Anti-Rationalization

Read references/anti-rationalization.md before proceeding. It contains the rationalization prevention table for this skill.

Entry Condition

Stage must be researched (research completed). You should have a requirements summary (from brainstorming) and research findings (from research) available in conversation context.

If research is not complete:

"The draft needs research findings as its foundation. Run /dp-cto:research first."

Step 1: Read the PRD Template

Use the Glob tool to find the PRD template in the installed plugin directory:

Glob for **/references/prd-template.md in the installed plugin directory. Read the template before writing. Use it as structure, not scripture. Adapt sections to the project -- skip what does not apply, but do not invent sections beyond what the template provides.

Step 2: Write the Full Document in One Pass

Read references/section-flows.md for the PRD section flow. Read references/writing-standards.md for the writing standards.

Write all sections in a single pass. Do NOT pause for section-by-section review.

Step 3: Devil's Advocate Pre-Check (MANDATORY)

Read references/precheck-categories.md for the complete pre-check categories and findings format.

Step 4: Present for Approval

Present the complete document and use AskUserQuestion with exactly three options:

• Approve — document is ready, proceed to challenge
• Revise — incorporate feedback (max 2 revision rounds, then must approve or reject)
• Reject — abort draft, return to brainstorming phase

If the user selects Revise, incorporate their feedback and present again with the same three options. Track revision rounds — after 2 revisions, only Approve or Reject remain.

If the user selects Reject, stop and print: "Draft rejected. Run /dp-cto:brainstorm to revisit the approach."

Step 5: Save the Document

Save as PRD-<title>.md in the current working directory.

Use a descriptive, hyphenated title derived from the document's subject. Example: PRD-Event-Driven-Auth-Service.md.

Handoff

Print exactly:

"Draft approved. Run /dp-cto:challenge to stress-test the document with adversarial review."

Do NOT invoke challenge. Do NOT start reviewing the document yourself. The user decides when to proceed.

<CHAIN> Draft complete. The next step in the spec pipeline is /dp-cto:challenge. The user decides when to run it. Do NOT auto-invoke /dp-cto:challenge. </CHAIN>

Anti-Patterns

Read references/anti-patterns.md for the common failure modes that compromise document quality.

NEVER

1. NEVER skip Alternatives Considered -- it is mandatory
2. NEVER fabricate claims that do not trace to discovery, brainstorming, or research
3. NEVER skip the devil's advocate pre-check before final approval
4. NEVER save the document without explicit user approval of the full document
5. NEVER auto-invoke challenge -- handoff only
6. NEVER skip reading the PRD template before writing
7. NEVER add sections beyond what the template defines unless the project demands it
8. NEVER allow more than 2 revision rounds -- after 2, only approve or reject

Red Flags -- STOP

Read references/red-flags.md before proceeding. It contains the stop conditions for this skill.
