[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 ATTENTION ask user whether to skip.

Critical Thinking Mindset — Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence >80% to act. Anti-hallucination: Never present guess as fact — cite sources for every claim, admit uncertainty freely, self-check output for errors, cross-reference independently, stay skeptical of own confidence — certainty without evidence root of all hallucination.

AI Mistake Prevention — Failure modes to avoid on every task: - Check downstream references before deleting. Deleting components causes documentation and code staleness cascades. Map all referencing files before removal. - Verify AI-generated content against actual code. AI hallucinates APIs, class names, and method signatures. Always grep to confirm existence before documenting or referencing. - Trace full dependency chain after edits. Changing a definition misses downstream variables and consumers derived from it. Always trace the full chain. - Trace ALL code paths when verifying correctness. Confirming code exists is not confirming it executes. Always trace early exits, error branches, and conditional skips — not just happy path. - When debugging, ask "whose responsibility?" before fixing. Trace whether bug is in caller (wrong data) or callee (wrong handling). Fix at responsible layer — never patch symptom site. - Assume existing values are intentional — ask WHY before changing. Before changing any constant, limit, flag, or pattern: read comments, check git blame, examine surrounding code. - Verify ALL affected outputs, not just the first. Changes touching multiple stacks require verifying EVERY output. One green check is not all green checks. - Holistic-first debugging — resist nearest-attention trap. When investigating any failure, list EVERY precondition first (config, env vars, DB names, endpoints, DI registrations, data preconditions), then verify each against evidence before forming any code-layer hypothesis. - Surgical changes — apply the diff test. Bug fix: every changed line must trace directly to the bug. Don't restyle or improve adjacent code. Enhancement task: implement improvements AND announce them explicitly. - Surface ambiguity before coding — don't pick silently. If request has multiple interpretations, present each with effort estimate and ask. Never assume all-records, file-based, or more complex path.

Quick Summary

Goal: Refine requirements into actionable user stories with BDD acceptance criteria and business rule traceability.

Workflow:

1. Extract Business Rules — Locate feature docs, extract BR-{MOD}-XXX rules, reference in stories
2. Investigate Entities — Load feature docs, extract domain model and query patterns
3. Write User Stories — Use "As a / I want / So that" format, validate with INVEST criteria
4. Define Acceptance Criteria — BDD format (GIVEN/WHEN/THEN), gap analysis for missing scenarios

Key Rules:

• Always reference existing business rules from docs/business-features/ before creating new ones
• User stories must pass INVEST criteria (Independent, Negotiable, Valuable, Estimable, Small, Testable)
• Include entity context and related domain model in every story
• MUST ATTENTION include story_points and complexity in all PBI/story outputs

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

• docs/project-reference/domain-entities-reference.md — Domain entity catalog, relationships, cross-service sync (read when task involves business entities/models) (content auto-injected by hook — check for [Injected:...] header before reading)

Business Rules Extraction (Project Domain)

When refining domain-related PBIs, automatically extract and reference existing business rules.

Step 1: Locate Related Feature Docs

Dynamic Discovery:

1. Run: Glob("docs/business-features/{module}/detailed-features/*.md") for feature docs
2. Or: Glob("docs/business-features/{module}/detailed-features/**/*.md") for nested features

From PBI frontmatter or module detection:

1. Check module field
2. Identify related feature from related_features list
3. Read discovered feature documentation

Step 2: Extract Existing Business Rules

From feature doc "Business Rules" section:

• Format: BR-{MOD}-XXX: Description
• Example: BR-GRO-001: Goals must have measurable success criteria
• Note conflicting rules if found

Step 3: Add to User Story

Include section:

## Related Business Rules

**From Feature Docs:**

- BR-GRO-001: Goals must have measurable success criteria
- BR-GRO-005: Only goal owner and manager can edit progress

**New Business Rules (if applicable):**

- BR-GRO-042: {New rule description}

**Conflicts/Clarifications:**

- {Note any conflicts with existing rules}

Token Budget

Target 8-12K tokens total (validated decision: prefer completeness):

• Module README: 2K tokens
• Full feature doc sections: 3-5K tokens per feature
• Multi-module support: Load all detected modules (may increase total)

Entity Domain Investigation

When refining domain-related PBIs, investigate related entities using feature docs.

Step 1: Load Feature Doc

Glob("docs/business-features/{module}/detailed-features/*.md")

Select file matching feature from PBI context.

Step 2: Extract Domain Model

From ## Domain Model section (Section 5):

• Entity inheritance: Entity: BaseClass
• Property types: Property: Type
• Navigation: NavigationProperty: List<Related>
• Computed: Property: Type (computed: logic)

Step 3: Correlate with Codebase

From ## File Locations section:

1. Read entity source file
2. Verify properties match documentation
3. Note any undocumented properties (flag for doc update)

Step 4: Identify Query Patterns

From ## Key Expressions section:

• Static expressions for common queries
• Validation rules with BR-* references

Step 5: Add to User Story

Include entity context:

## Entity Context

**Primary:** {Entity} - {description}
**Related:** {Entity1}, {Entity2}
**Key Queries:** {ExpressionName}
**Source:** {path}

This ensures implementation uses correct entities and patterns.

Core Capabilities

1. Requirements Refinement

• Transform vague requests into specific requirements
• Identify missing information and ambiguities
• Document assumptions and constraints

2. User Story Writing

Format

As a {user role/persona}
I want {goal/desire}
So that {benefit/value}

INVEST Criteria

• Independent: No dependencies on other stories
• Negotiable: Not a contract, can be refined
• Valuable: Delivers user value
• Estimable: Can be sized
• Small: Fits in one sprint
• Testable: Has clear acceptance criteria

3. Acceptance Criteria (BDD Format)

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

For Project Domain:

1. Reference existing test case patterns from feature docs
2. Use TC-{FEATURE}-{NNN} format (e.g., TC-GM-001)
3. Include Evidence field: file:line format
4. Example from GoalManagement feature: TC-GRO-GOAL-001: Create goal with valid data GIVEN employee has permission to create goals WHEN employee submits goal form with all required fields THEN goal is created and appears in goal list Evidence: goal.service.ts:87, goal.component.ts:142

4. Business Rules Documentation

Rule Format

BR-{MOD}-{NNN}: {Rule name}
IF {condition}
THEN {action/result}
ELSE {alternative}
Evidence: {file}:{line}

5. Gap Analysis

• Current state vs desired state mapping
• Identify process improvements
• Document integration requirements

Context Validation (Project Domain)

Before finalizing user story:

Cross-Reference Check

• Business rules don't conflict with existing BR-{MOD}-XXX rules
• Test case format matches existing TC-{FEATURE}-{NNN} patterns
• Entity names match those in feature docs
• Evidence format follows file:line convention

Documentation Links

Add to user story:

## Reference Documentation

- Feature Doc: `docs/business-features/{module}/detailed-features/{feature}.md`
- Related Entities: `docs/business-features/{module}/detailed-features/*.md`
- Existing Test Cases: See feature doc Section 15 (Test Specifications)

If conflicts found, note in "Unresolved Questions" section.

## Post-Refinement Validation (MANDATORY)

**Every refinement must end with a validation interview.**

After completing user story or PBI refinement, conduct validation to:

1. Surface hidden assumptions
2. Confirm critical decisions
3. Identify potential concerns
4. Brainstorm with user on alternatives

### Validation Interview Process

Use `AskUserQuestion` tool with 3-5 questions:

| Category        | Example Questions                       |
| --------------- | --------------------------------------- |
| Assumptions     | "We assume X. Is this correct?"         |
| Scope           | "Should Y be explicitly excluded?"      |
| Dependencies    | "Does this depend on Z being ready?"    |
| Edge Cases      | "What happens when data is empty/null?" |
| Business Impact | "Will this affect existing reports?"    |

### Document Validation Results

Add to user story/PBI:

Validation Summary

Validated: {date}

Confirmed Decisions

• {decision}: {user choice}

Concerns Raised

• {concern}: {resolution}

Action Items

• [ ] {follow-up if any}

### When to Flag for Stakeholder Review

- Decision impacts other teams
- Scope change requested
- Technical risk identified
- Business rule conflict detected

**This step is NOT optional - always validate before marking refinement complete.**

## Closing Reminders

- **MANDATORY IMPORTANT MUST ATTENTION** break work into small todo tasks using `TaskCreate` BEFORE starting
- **MANDATORY IMPORTANT MUST ATTENTION** search codebase for 3+ similar patterns before creating new code
- **MANDATORY IMPORTANT MUST ATTENTION** cite `file:line` evidence for every claim (confidence >80% to act)
- **MANDATORY IMPORTANT MUST ATTENTION** add a final review todo task to verify work quality
- **MUST ATTENTION** apply critical thinking — every claim needs traced proof, confidence >80% to act. Anti-hallucination: never present guess as fact.
- **MUST ATTENTION** apply AI mistake prevention — holistic-first debugging, fix at responsible layer, surface ambiguity before coding, re-read files after compaction.

**[TASK-PLANNING]** Before acting, analyze task scope and systematically break it into small todo tasks and sub-tasks using TaskCreate.
