Quick Summary
Goal: Refine requirements into actionable user stories with BDD acceptance criteria and business rule traceability.
Workflow:
- Extract Business Rules — Locate feature docs, extract BR-{MOD}-XXX rules, reference in stories
- Investigate Entities — Load feature docs, extract domain model and query patterns
- Write User Stories — Use "As a / I want / So that" format, validate with INVEST criteria
- Define Acceptance Criteria — BDD format (GIVEN/WHEN/THEN), gap analysis for missing scenarios
Key Rules:
- Always reference existing business rules from
docs/specs/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_pointsandcomplexityin all PBI/story outputs - [BLOCKING] Tech-agnostic output: story/acceptance-criteria prose follows
docs/project-reference/spec-principles.md§3 — no framework/product/language/design-pattern names; source paths, class names, and test identifiers appear ONLY in evidence fields (**Evidence**,IntegrationTest,[Source:]), frontmatter, and Mermaid.
Be skeptical. Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence percentages (Idea should be more than 80%).

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:
- Run:
Glob("docs/specs/{module}/*.md")for feature docs - Or:
Glob("docs/specs/{module}/**/*.md")for nested features
From PBI frontmatter or module detection:
- Check
modulefield - Identify related feature from
related_featureslist - 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/specs/{module}/*.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:
- Read entity source file
- Verify properties match documentation
- 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:
- Reference existing test case patterns from feature docs
- Use TC-{FEATURE}-{NNN} format (e.g., TC-GM-001)
- Include Evidence field:
[Source: namespace/service/id]abstract-anchor format — never physical code coordinates or repository-root paths (stack-portable; seeshared/tc-format.md) - Example from InvoiceManagement feature:
TC-INV-001: Create invoice with valid data GIVEN user has permission to create invoices WHEN user submits invoice form with all required fields THEN invoice is created and appears in invoice list Evidence: [Source: operation/sales/CreateInvoice], [Source: component/sales/Invoice]
4. Business Rules Documentation
Rule Format
BR-{MOD}-{NNN}: {Rule name}
IF {condition}
THEN {action/result}
ELSE {alternative}
Evidence: [Source: rule/{service}/{RuleName}]
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 the abstract-anchor convention (
[Source: namespace/service/id]) — no physical code coordinates or repository-root paths
Documentation Links
Add to user story:
## Reference Documentation
- Feature Doc: `docs/specs/{module}/{feature}.md`
- Related Entities: `docs/specs/{module}/*.md`
- Existing Test Cases: See feature doc Section 8 (Test Specifications)
If conflicts found, note in "Unresolved Questions" section.

Quality Checklist
Before completing BA artifacts:
- User story follows "As a... I want... So that..." format
- At least 3 scenarios: happy path, edge case, error case
- All scenarios use GIVEN/WHEN/THEN
- Out of scope explicitly listed
- Story meets INVEST criteria
- No solution-speak in requirements (only outcomes)
- Existing BRs referenced (if domain-related)
- TC format matches feature docs (if domain-related)
- Entity names use domain vocabulary
Post-Refinement Validation (MANDATORY)
Every refinement must end with a validation interview.
After completing user story or PBI refinement, conduct validation to:
- Surface hidden assumptions
- Confirm critical decisions
- Identify potential concerns
- 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.
<!-- SYNC:ai-mistake-prevention -->[IMPORTANT] Use
TaskCreateto 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.
<!-- /SYNC:ai-mistake-prevention --> <!-- SYNC:critical-thinking-mindset -->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. Keep domain concepts out of generic/shared/infrastructure layers. A reusable layer (shared library, framework, infra module) must reference NO consumer-specific domain concept — tenant/customer/product IDs, business entities, feature rules. The leak compiles and runs, so it passes review silently while coupling the "reusable" layer to one consumer. Push domain fields/logic down into the consumer via subclass or composition.
