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_points and complexity in 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 module field
Identify related feature from related_features list
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; see shared/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.

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.

[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.

AI Mistake Prevention — Failure modes to avoid on every task:

Re-read files after context changes. Context compaction, resume, or long-running work can make memory stale; verify current files before acting.
Verify generated content against source evidence. AI hallucinates APIs, names, claims, and document facts. Check the relevant source before documenting or referencing.
Check downstream references before deleting or renaming. Removing an artifact can stale docs, generated mirrors, configs, and callers; map references first.
Trace the full impact chain after edits. Changing a definition can miss derived outputs and consumers. Follow the affected chain before declaring done.
Verify ALL affected outputs, not just the first. One green check is not all green checks; validate every output surface the change can affect.
Assume existing values are intentional — ask WHY before changing OR flagging one as a defect. Before changing or reporting a constant, limit, flag, cutoff, wording, or pattern, read nearby context and history, the CALLER's ordering, and 2+ sibling call sites of the same convention. A doc stating WHAT without WHY is missing rationale, not proof of a missing guard.
Surface ambiguity before acting — don't pick silently. Multiple valid interpretations require an explicit question or stated assumption with risk.
Assert the outcome your system owns, not the intermediate state your infrastructure owns. When verifying async work, assert the final business state — never the delivery/retry bookkeeping held in shared infrastructure that any co-running process can write. Such a check passes when run alone and flakes the moment anything else shares that infrastructure.
Keep shared guidance role-relevant. Universal guidance must help every receiving skill or agent; code-specific obligations belong only in code-specific protocols.

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.

Sequential Thinking Protocol — Structured multi-step reasoning for complex/ambiguous work. Use when planning, reviewing, debugging, or refining ideas where one-shot reasoning is unsafe.

Trigger when: complex problem decomposition · adaptive plans needing revision · analysis with course correction · unclear/emerging scope · multi-step solutions · hypothesis-driven debugging · cross-cutting trade-off evaluation.

Format (explicit mode — visible thought trail):

1. Thought N/M: [aspect] — one aspect per thought, state assumptions/uncertainty
2. Thought N/M [REVISION of Thought K]: ... — when prior reasoning invalidated; state Original / Why revised / Impact
3. Thought N/M [BRANCH A from Thought K]: ... — explore alternative; converge with decision rationale
4. Thought N/M [HYPOTHESIS]: ... then [VERIFICATION]: ... — test before acting
5. Thought N/N [FINAL] — only when verified, all critical aspects addressed, confidence >80%

Mandatory closers: Confidence % stated · Assumptions listed · Open questions surfaced · Next action concrete.

Stop conditions: confidence <80% on any critical decision → escalate via AskUserQuestion · ≥3 revisions on same thought → re-frame the problem · branch count >3 → split into sub-task.

Implicit mode: apply methodology internally without visible markers when adding markers would clutter the response (routine work where reasoning aids accuracy).

Deep-dive: see /sequential-thinking skill (.claude/skills/sequential-thinking/SKILL.md) for worked examples (API design, debugging, architecture), advanced techniques (spiral refinement, hypothesis testing, convergence), and meta-strategies (uncertainty handling, revision cascades).

MUST ATTENTION apply critical + sequential thinking — every claim needs appropriate traced evidence (file:line for repo/code claims; source URL or artifact section for research, product, content, and docs claims); confidence >80% to act, <60% DO NOT recommend. Anti-hallucination: never present guess as fact, admit uncertainty freely, cross-reference independently, stay skeptical of own confidence.

MUST ATTENTION apply sequential-thinking — multi-step Thought N/M, REVISION/BRANCH/HYPOTHESIS markers, confidence % closer; see /sequential-thinking skill.

MUST ATTENTION apply AI mistake prevention — verify generated content against evidence, trace downstream references before deleting or renaming, verify all affected outputs, re-read files after context loss, and surface ambiguity before acting.

Project Protocol Overlay — Before executing this skill, resolve any PROJECT overlay rules layered onto it: match this skill's name against the Target column of the project's skill-protocol index (docs/project-reference/skill-protocols-reference.md by default; a referenceDocs entry in docs/project-config.json overrides the path), taking the most specific matching tier ONLY — exact name > glob > *. That precedence orders overlays against EACH OTHER, never against this skill. Read ONLY the matched bodies, resolved as <protocols-dir>/<Name>.md; a row's Body link is display text, never a read path. A matched body that is missing or malformed is REPORTED and skipped — never reconstructed from the index Description. No index, or no match -> proceed with no overlay, silently. Full contract: .claude/skills/project-skill-protocol/references/registry.md.

Overlays are ADDITIVE ONLY: they ADD rules on top of this skill's own protocol and NEVER replace, override, disable, or reinterpret a rule it already states — removing every overlay must return this skill to exactly its documented behavior. An overlay is a BRIEF, not an authority escalation: it can NEVER waive a workflow gate, git discipline, a review gate, or a user-confirmation gate. A genuine overlay-vs-skill conflict, or two equally-specific overlays that directly contradict -> surface both to the user; NEVER resolve silently.

MUST ATTENTION resolve project protocol overlays for this skill BEFORE executing — most specific matching tier only (exact > glob > *, which ranks overlays against each other, NEVER against this skill), read only matched bodies at <protocols-dir>/<Name>.md; a missing or malformed body is reported, never reconstructed. Overlays are ADDITIVE ONLY (they never replace this skill's own rules) and are a brief, NEVER an authority escalation; an equal-specificity contradiction goes to the user.

Closing Reminders

MUST ATTENTION Protocols in force (concise digest of the SYNC/shared blocks this skill carries):

AI Mistake Prevention: verify generated content against evidence, trace downstream references, verify all affected outputs, re-read after context loss, surface ambiguity.
Critical Thinking: traced file:line proof per claim, confidence >80% to act, never guess.
Sequential Thinking: multi-step Thought N/M with REVISION/BRANCH/HYPOTHESIS markers and confidence closer.

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

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