Create PRD

Create a business-focused Product Requirements Document through structured brainstorming.

Required Inputs

• Feature name or product idea.
• Optional: existing _prd.md file for update mode.

Workflow

1. Determine the project name and working directory.

   • Derive the slug from the feature name provided by the user.
   • Use tasks/prd-<slug>/ as the target directory.
   • If _prd.md already exists in the target directory, read it and operate in update mode.
   • If the directory does not exist, create it.
   • Create tasks/prd-<slug>/adrs/ directory if it does not exist.

2. Discover context through parallel research.

   • Spawn one Agent tool call to explore the codebase for relevant patterns, existing features, and architecture.
   • Spawn a second Agent tool call to perform 3-5 web searches for market trends, competitive analysis, and user needs.
   • Merge findings from both agents before proceeding to questions.

3. Ask clarifying questions following references/question-protocol.md.

   • Focus exclusively on WHAT features users need, WHY it provides business value, and WHO the target users are.
   • Ask about success criteria and constraints.
   • Never ask technical implementation questions about databases, APIs, frameworks, or architecture.
   • Ask at most 3 questions per round and wait for answers before the next round.
   • Complete at least one full clarification round before presenting approaches.

4. Present product approaches.

   • Offer 2-3 product approaches with trade-offs for each.
   • Lead with the recommended approach and explain why it is preferred.
   • Wait for the user to select an approach before continuing.
   • After the user selects an approach, create an ADR for this decision:
     • Read references/adr-template.md.
     • Determine the next ADR number by listing existing files in tasks/prd-<slug>/adrs/.
     • Fill the template: the selected approach as "Decision", rejected approaches as "Alternatives Considered" with their trade-offs, and outcomes as "Consequences". Set Status to "Accepted" and Date to today.
     • Write the ADR to tasks/prd-<slug>/adrs/adr-NNN.md (zero-padded 3-digit number, e.g., adr-001.md).

5. Refine the chosen approach.

   • Ask targeted follow-up questions based on the selected approach.
   • Confirm key decisions about scope, phasing, and success criteria with the user before generating the document.
   • If the user makes a significant scope decision during refinement (e.g., including or excluding a major feature, choosing a phasing strategy), create an additional ADR for that decision following the same process as step 4.

6. Generate the PRD document.

   • Read references/prd-template.md and fill every section with the gathered context.
   • Include an "Architecture Decision Records" section listing all ADRs created during this session with their numbers, titles, and one-line summaries as links to the adrs/ directory.
   • Write the completed document to tasks/prd-<slug>/_prd.md.
   • The PRD must describe user capabilities and business outcomes only.
   • No databases, APIs, code structure, frameworks, testing strategies, or architecture decisions.

Error Handling

• If the user provides insufficient context to complete a section, note it in the Open Questions section rather than guessing.
• If web research tools are unavailable, proceed with codebase exploration only and note the limitation.
• If the target directory cannot be created, stop and report the filesystem error.
• If operating in update mode, preserve sections the user has not asked to change.
