[IMPORTANT] Use TaskCreate to break ALL work into small tasks BEFORE starting — including tasks for each file read. This prevents context loss from long files. For simple tasks, AI MUST ask user whether to skip.

External Memory: For complex or lengthy work (research, analysis, scan, review), write intermediate findings and final results to a report file in plans/reports/ — prevents context loss and serves as deliverable.

Evidence Gate: MANDATORY IMPORTANT MUST — every claim, finding, and recommendation requires file:line proof or traced evidence with confidence percentage (>80% to act, <80% must verify first).

• docs/test-specs/ — Test specifications by module (read existing TCs for related features; recommend test spec generation for new PBIs)

Quick Summary

Goal: Transform raw ideas into actionable Product Backlog Items using BA best practices, hypothesis validation, and domain research.

Workflow:

1. Idea Intake — Load artifact, detect project module
2. Domain Research — WebSearch for market/competitor context
3. Problem Hypothesis — Validate problem exists before building
4. Elicitation — Apply BABOK techniques to extract requirements
5. Acceptance Criteria — Write BDD GIVEN/WHEN/THEN scenarios (min 3)
6. Prioritization — Apply RICE/MoSCoW scoring
7. Validation Interview — MANDATORY user interview to confirm assumptions
8. PBI Generation — Save artifact to team-artifacts/pbis/

Key Rules:

Frontend/UI Context (if applicable)

When this task involves frontend or UI changes,

UI System Context — For frontend/UI/styling tasks, MUST READ these BEFORE implementing: frontend-patterns-reference.md (component base classes, stores, forms), scss-styling-guide.md (BEM methodology, SCSS vars, responsive), design-system/README.md (design tokens, component inventory, icons). MUST READ .claude/skills/shared/ui-system-context.md for full protocol and checklists.

• Component patterns: docs/project-reference/frontend-patterns-reference.md (content auto-injected by hook — check for [Injected: ...] header before reading)

• Styling/BEM guide: docs/project-reference/scss-styling-guide.md

• Design system tokens: docs/project-reference/design-system/README.md

• Never skip hypothesis validation for new features

• Validation interview is NOT optional — always ask 3-5 questions

• Use project domain-specific vocabulary when available

• MUST include story_points and complexity in PBI output (see .claude/skills/shared/estimation-framework.md)

• docs/project-reference/domain-entities-reference.md — Domain entity catalog, relationships, cross-service sync (read when task involves business entities/models)

• Scaffold Production Readiness — Production scaffold checklist: health endpoints, structured logging, graceful shutdown, config validation, CI pipeline, Dockerfile, env separation. Verify each item exists before marking scaffold complete. MUST READ .claude/skills/shared/scaffold-production-readiness-protocol.md for full protocol and checklists. — for Production Readiness Concerns table in PBI output

• Cross-Cutting Quality — Check: error handling consistency, logging standards, security headers, input validation, rate limiting, CORS config, health checks across all services. MUST READ .claude/skills/shared/cross-cutting-quality-concerns-protocol.md for full protocol and checklists. — for Authorization, Seed Data, Data Migration concerns in PBI output

Greenfield Mode

Auto-detected: If no existing codebase is found (no code directories like src/, app/, lib/, server/, packages/, etc., no manifest files like package.json/*.sln/go.mod, no populated project-config.json), this skill switches to greenfield mode automatically. Planning artifacts (docs/, plans/, .claude/) don't count — the project must have actual code directories with content.

When greenfield is detected:

1. Skip existing backlog item refinement (no backlog exists yet)
2. Enable DDD domain modeling: bounded contexts, aggregates, entities, value objects
3. Enable constraint capture: team skills, expected scale, hosting preferences, budget — as input signals for later tech stack research
4. Use WebSearch for market research and competitor analysis
5. Output domain model artifact alongside PBI artifact
6. Increase AskUserQuestion frequency — validate domain boundaries, entity relationships, business rules
7. [CRITICAL] DO NOT ask about tech stack during refinement. Tech stack is a research-driven decision that comes in a dedicated phase after business analysis. Capture team skills and scale expectations as input signals only.

Be skeptical. Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence percentages (Idea should be more than 80%).

Idea Refinement to PBI

Transform captured ideas into actionable Product Backlog Items using Business Analysis best practices, Hypothesis-Driven Development, and domain research.

When to Use

• Idea artifact ready for refinement
• Need to validate problem hypothesis before building
• Converting concept to implementable item
• Adding acceptance criteria to requirements
• Researching domain/market context for new features

Workflow Overview

Output

• Path: team-artifacts/pbis/{YYMMDD}-pbi-{slug}.md
• ID Pattern: PBI-{YYMMDD}-{NNN}

Phase 0: Locate Active Plan (if in workflow)

If running within a workflow (big-feature, greenfield-init, etc.):

1. Search for active plan — Glob plans/*/plan.md sorted by modification time, or check TaskList for plan context
2. Read plan.md — understand project scope, goals, architecture decisions, domain model
3. Read existing research — {plan-dir}/research/*.md for business evaluation, domain analysis, architecture design
4. Read docs/project-reference/domain-entities-reference.md (if exists) — understand existing domain entities
5. Use plan context to inform PBI refinement (don't re-ask questions already answered in prior steps)

Phase 1: Idea Intake & Context Loading

1. Read idea artifact from path or find by ID in team-artifacts/ideas/
2. Extract: problem statement, value proposition, target users, scope
3. Check module field for project domain; if absent, detect via keywords or prompt user

Phase 2: Domain Research

Trigger: New domain, unclear competitors, --research flag. Skip: Internal tooling, well-understood domain, time-constrained.

Use WebSearch with domain terms. Summarize in max 3 bullets (market context, competitors, best practices).

Phase 3: Problem Hypothesis Validation

Draft and validate hypothesis with user via AskUserQuestion. 42% of startups fail due to no market need - validate before building.

Skip: --skip-hypothesis, validated hypothesis exists, bug fix/tech debt.

Problem Hypothesis Template

**We believe** [target users/persona]
**Experience** [specific problem]
**Because** [root cause]
**We'll know this is true when** [validation metric/evidence]

Value Hypothesis Template

**We believe** [feature/solution]
**Will deliver** [value/benefit]
**To** [target users]
**We'll know we're right when** [success metric]

Validation Process

1. Draft hypothesis from idea content
2. Use AskUserQuestion to validate:
   • "Is this the core problem we're solving?"
   • "Who exactly experiences this? How often?"
   • "What evidence do we have this problem exists?"
3. If validated, proceed to elicitation
4. If invalidated, return idea for clarification

Phase 4: Requirements Elicitation (BABOK Core 5)

Select technique based on context:

1. Interviews

When: Deep individual insights needed, stakeholder perspectives vary Process: Prepare open-ended questions (why, how, what-if) → active listening → follow-up on unexpected answers → document verbatim quotes Output: Stakeholder needs, pain points, constraints

2. Workshops

When: Group consensus needed, complex requirements, multiple stakeholders Process: Define agenda + timebox (90 min max) → neutral facilitator → capture all voices (round-robin, silent voting) → document decisions and dissent Output: Prioritized requirements, consensus decisions

3. Document Analysis

When: Existing systems/processes to understand, regulatory requirements Process: Gather artifacts (specs, manuals, code) → extract implicit requirements → note gaps → cross-reference with stakeholder input Output: As-is state, compliance requirements, gaps

4. Observation (Job Shadowing)

When: Understand real workflow, users can't articulate needs Process: Shadow users → note workarounds/pain points → don't interrupt → ask clarifying questions afterward Output: Actual vs stated workflow, hidden requirements

5. Prototyping

When: Visual validation needed, UI/UX requirements unclear Process: Start low-fidelity (sketches, wireframes) → iterate on feedback → increase fidelity as requirements stabilize → document design decisions Output: Validated UI requirements, interaction patterns

Phase 5: Acceptance Criteria (BDD Format)

Write GIVEN/WHEN/THEN scenarios. Minimum 3: happy path, edge case, error case.

Standard BDD Format

Scenario: {Descriptive title}
  Given {precondition/context}
    And {additional context}
  When {action/trigger}
    And {additional action}
  Then {expected outcome}
    And {additional verification}

Best Practices

Example Scenarios

Scenario: Employee creates goal with valid data
  Given employee has permission to create goals
    And employee is on the goal creation page
  When employee submits goal form with all required fields
  Then goal is created with status "Draft"
    And goal appears in employee's goal list

Scenario: Goal creation fails with missing required field
  Given employee is on the goal creation page
  When employee submits form without title
  Then validation error "Title is required" is displayed
    And goal is not created

Scenario: Manager reviews subordinate goal
  Given manager has direct reports
    And subordinate has submitted goal for review
  When manager opens goal review page
  Then subordinate's goal is visible with "Pending Review" status

Project Test Case Format

• Format: TC-{FEATURE}-{NNN} (e.g., TC-GM-001)
• Evidence: file:line format
• See business-analyst skill for detailed patterns

Phase 5.5: Testability Assessment

Use AskUserQuestion with 2-3 questions:

1. "Which testing approach fits this PBI?"

   • TDD-first: Write test specs before implementation (Recommended for complex features)
   • Implement-first: Build feature, then create test specs
   • Parallel: Spec and implement simultaneously

2. "What test levels are needed?"

   • Integration tests only (Recommended for backend CQRS)
   • Integration + E2E
   • Unit + Integration + E2E

For EACH acceptance criterion, generate a corresponding test case outline:

This table becomes the seed for /tdd-spec if the user chooses TDD-first.

Document in PBI under ## Testability Assessment.

Phase 6: Prioritization & Estimation

Estimation Framework — SP scale: 1(trivial) → 2(small) → 3(medium) → 5(large) → 8(very large, high risk) → 13(epic, SHOULD split) → 21(MUST split). MUST provide story_points and complexity estimate after investigation. MUST READ .claude/skills/shared/estimation-framework.md for full protocol and checklists. for story point scale and complexity definitions.

Apply RICE score or MoSCoW for priority. Estimate using Story Points (Modified Fibonacci 1-21) for complexity measurement.

Story Points (Primary Estimation)

See shared/estimation-framework.md for SP reference table.

Quick RICE Score

Score = (Reach x Impact x Confidence) / Effort

Reach: Users affected per quarter (100, 500, 1000+)
Impact: 0.25 (minimal) | 0.5 (low) | 1 (medium) | 2 (high) | 3 (massive)
Confidence: 0.5 (low) | 0.8 (medium) | 1.0 (high)
Effort: Story points (1, 2, 3, 5, 8, 13, 21)

MoSCoW Categories

Phase 7: Validation Interview (MANDATORY)

Generate 3-5 questions covering assumptions, scope, dependencies, edge cases. Use AskUserQuestion. Document in PBI. This step is NOT optional.

Anti-Patterns to Avoid

Key Rules

• Every PBI MUST include a Dependencies table — with types: must-before, can-parallel, blocked-by, independent. This enables /prioritize and /plan to respect ordering.
• No vague dependency descriptions — Each dependency must specify the concrete PBI, service, or feature and WHY the relationship exists.

Definition of Ready (INVEST)

Project Integration

For domain PBIs: detect module (ref: .claude/skills/shared/module-detection-keywords.md), extract business rules from docs/business-features/{module}/, load entity context from .ai.md. Target 8-12K tokens for feature context.

Related

• Role Skill: business-analyst (detailed patterns)
• Input: /idea output
• Next Step: /story, /tdd-spec (Recommended for TDD), /test-spec, /design-spec
• Prioritization: /prioritize

Next Steps

MANDATORY IMPORTANT MUST after completing this skill, use AskUserQuestion to recommend:

• "/story (Recommended)" — Break PBI into implementable user stories
• "/pbi-mockup" — Generate HTML mockup report from PBI
• "/tdd-spec" — If using TDD approach
• "Skip, continue manually" — user decides

Closing Reminders

MANDATORY IMPORTANT MUST break work into small todo tasks using TaskCreate BEFORE starting. MANDATORY IMPORTANT MUST validate decisions with user via AskUserQuestion — never auto-decide. MANDATORY IMPORTANT MUST add a final review todo task to verify work quality. MANDATORY IMPORTANT MUST READ the following files before starting:

• MUST READ .claude/skills/shared/ui-system-context.md before starting
• MUST READ .claude/skills/shared/scaffold-production-readiness-protocol.md before starting
• MUST READ .claude/skills/shared/cross-cutting-quality-concerns-protocol.md before starting
• MUST READ .claude/skills/shared/estimation-framework.md before starting
