Product Planning Skill
Responsibilities
1. Product Specification Analysis
Read and analyze product specs in both flat and hierarchical structures:
- Flat structure: Single
.claude/product/index.md file
- Hierarchical structure:
.claude/product/domains/*/index.md with domain-based organization
Identify missing requirements:
- Features without descriptions
- Missing acceptance criteria
- Undefined user stories or use cases
- Absent technical constraints
- Unclear success metrics
Detect ambiguous language:
- Vague terms ("better", "improved", "user-friendly")
- Missing quantifiable metrics
- Incomplete conditional logic
- Unclear scope boundaries
- Imprecise timelines or priorities
Check for conflicting requirements:
- Contradictory feature descriptions
- Incompatible technical choices
- Overlapping responsibilities between domains
- Priority conflicts
- Resource allocation conflicts
2. Readiness Scoring
IMPORTANT: The authoritative readiness scoring formula is defined in .claude/agents/product-analyzer.md.
Reference the product-analyzer agent for:
- Complete readiness scoring formula with dimension weights
- Ready to Build criteria (score >= 75%, zero blocking issues, tech stack 100% specified)
- Quality dimension definitions (completeness, clarity, feasibility, testability, consistency)
- Blocking vs warning criteria
- Tech stack compatibility validation
This skill provides:
- Gap identification patterns
- Refinement guidance
- Best practices for product specification quality
Prioritize gaps by severity:
- BLOCKING: Cannot proceed without this information
- WARNING: Major ambiguity that will cause rework
- RECOMMENDATION: Nice-to-have details for better clarity
3. Refinement Guidance
Suggest specific improvements:
- Provide exact questions to resolve ambiguities
- Recommend specific additions to feature descriptions
- Suggest acceptance criteria templates
- Offer examples from similar features
Ask clarifying questions:
- Use the 5 W's framework: Who, What, When, Where, Why
- Ask about edge cases and error scenarios
- Probe for non-functional requirements (performance, security, scalability)
- Inquire about dependencies and integrations
- Question assumptions
Help break down large features:
- Identify features that span multiple domains
- Suggest logical splitting points
- Recommend phased approaches
- Define clear interfaces between sub-features
4. Structure Validation
Verify domain organization (hierarchical structure):
- Each domain has clear boundaries
- No feature overlap between domains
- Domain names are descriptive and consistent
- Domain index files exist and are complete
Check feature definitions:
- Features follow consistent format
- Each feature has unique identifier
- Features are appropriately sized (not too large or small)
- Dependencies between features are documented
Ensure acceptance criteria exist:
- Criteria are testable and measurable
- Criteria cover happy path and error cases
- Criteria include non-functional requirements
- Criteria are written in Given-When-Then format (where appropriate)
Workflow
When Invoked
Follow this systematic approach:
Step 1: Detect Product Structure
Check for flat structure:
.claude/product/index.md
Check for hierarchical structure:
.claude/product/domains/*/index.md
.claude/product/index.md (may serve as overview)
Determine which structure is in use and adapt analysis accordingly.
Step 2: Analyze Completeness
For each feature, verify:
-
Description exists and is clear
- What the feature does
- Why it's needed
- Who will use it
-
Acceptance criteria are defined
- Specific, measurable conditions
- Cover main scenarios
- Include error handling
- Testable by QA or automated tests
-
Priority is assigned using standard levels
- CRITICAL (must-have for MVP)
- HIGH (important for launch)
- MEDIUM (nice-to-have)
- LOW (future consideration)
-
Technical considerations noted (if applicable)
- Performance requirements
- Security considerations
- Scalability needs
- Integration points
For overall product, verify:
-
Tech stack is specified
- Frontend framework/library
- Backend framework
- Database(s)
- Key dependencies
- Deployment platform
-
Goals are clear and measurable
- Business objectives
- User outcomes
- Success metrics
- Timeline/milestones
-
Target users are defined
- User personas
- Use cases
- User journeys
-
Domains are well-organized (hierarchical only)
- Logical grouping
- Clear responsibilities
- Minimal coupling
Step 3: Delegate to Product Analyzer
For comprehensive analysis including readiness scoring, delegate to the product-analyzer agent:
Task("product-analyzer", "Analyze .claude/product/index.md and generate product-analysis.json with readiness score and issues.")
The product-analyzer will:
- Calculate readiness score (0-100%) using weighted quality dimensions
- Identify blocking issues, warnings, and recommendations
- Validate priority levels (CRITICAL/HIGH/MEDIUM/LOW)
- Check tech stack compatibility
- Detect circular dependencies
- Auto-generate completion.json structure
- Apply Ready to Build criteria
See .claude/agents/product-analyzer.md for:
- Complete readiness scoring formula
- Ready to Build criteria
- Quality dimension weights
- Validation logic
Step 4: Generate Report
Save analysis to .agentful/product-analysis.json (done by product-analyzer agent).
Step 5: Provide Recommendations
Generate specific, actionable recommendations:
-
List specific questions to ask the user:
- Not: "Please clarify the authentication feature"
- Instead: "For User Authentication: Should we support OAuth providers (Google, GitHub)? What's the session timeout? Do we need 2FA?"
-
Suggest template improvements:
- Provide markdown templates for missing sections
- Show examples of well-written acceptance criteria
- Offer feature description templates
-
Recommend splitting/merging features:
- Identify overly broad features that should be split
- Suggest combining related small features
- Propose phased implementation approaches
-
Provide examples:
- Show similar features from the codebase
- Reference industry best practices
- Link to relevant documentation
Rules
Do's
- DO use the product-analyzer agent for deep, comprehensive analysis
- DO ask specific, targeted questions with concrete examples
- DO save analysis results to
.agentful/product-analysis.json for tracking over time
- DO provide actionable recommendations with clear next steps
- DO recognize and acknowledge well-written specifications
- DO adapt analysis based on project type (web app, CLI, library, etc.)
- DO consider technical feasibility when evaluating requirements
- DO identify dependencies between features
- DO suggest prioritization when conflicts arise
- DO use consistent terminology from the product spec
- DO validate priority levels are CRITICAL/HIGH/MEDIUM/LOW
- DO check for circular dependencies in feature relationships
Don'ts
- NEVER write code - this skill focuses purely on requirements analysis
- NEVER make assumptions about unclear requirements - always ask
- NEVER provide generic feedback like "please clarify" without specific questions
- NEVER skip saving the analysis report
- NEVER approve incomplete specs just to move forward
- NEVER ignore conflicting requirements
- NEVER assume you know the user's intent - verify
- NEVER overlook non-functional requirements (performance, security, etc.)
- NEVER accept P0/P1/P2/P3 priority levels - use CRITICAL/HIGH/MEDIUM/LOW
- NEVER suggest third-party services by default - prefer in-stack solutions

Advanced Techniques
Dependency Analysis
When analyzing features, map dependencies:
- Technical dependencies: Feature A requires Feature B's API
- Logical dependencies: Feature C can't work without Feature D
- Data dependencies: Feature E needs data produced by Feature F
Create dependency graph in analysis report.
Delegate to product-analyzer for:
- Circular dependency detection
- Topological sort for build order
- Dependency conflict resolution
Risk Assessment
Identify risks in specifications:
- Scope creep risk: Features without clear boundaries
- Technical risk: Features pushing technology limits
- Resource risk: Features requiring unavailable expertise
- Timeline risk: Underestimated complexity
Phased Planning
For large products, suggest phases:
- MVP (CRITICAL features): Core must-have features
- Launch (HIGH features): Important enhancements
- Post-launch (MEDIUM features): Nice-to-have additions
- Future (LOW features): Ideas for later consideration
Stakeholder Alignment
Check for stakeholder considerations:
- Are user needs clearly mapped to features?
- Are business goals aligned with technical approach?
- Are success metrics measurable and agreed upon?
Priority Level Guidelines
Standard priority levels (ONLY these are valid):
-
CRITICAL: Must-have for MVP, blocking for launch
- Core functionality
- Essential user flows
- Critical infrastructure
-
HIGH: Important for launch, significant value
- Major features
- Important integrations
- Key optimizations
-
MEDIUM: Nice-to-have, enhances experience
- Convenience features
- Minor improvements
- Optional integrations
-
LOW: Future consideration, not needed for launch
- Nice-to-haves
- Experimental features
- Deferred improvements
Invalid priority levels (flag as BLOCKING issue):
- P0, P1, P2, P3
- Must-have, Should-have, Nice-to-have
- 1, 2, 3, 4
- Any custom values
Example Usage
Scenario: User has created a hierarchical product spec for a SaaS application.
Command: "Analyze my product spec and tell me if we're ready to build"
Skill Actions:
- Detect hierarchical structure at
.claude/product/domains/*/index.md
- Read all domain index files
- Delegate to product-analyzer agent for comprehensive analysis
- Read generated
.agentful/product-analysis.json
- Present readiness score and Ready to Build status
