# Quality Gate Analysis: Comprehensive Review of craft.md Quality System
**Date:** 2025-01-13
**Reviewer:** Claude (Sonnet 4.5)
**Context:** User requested comprehensive review of quality gates for sufficiency, redundancy, and question adequacy
**Scope:** All quality gates across craft.md Phases 1-4
---
## Executive Summary
### Purpose
This analysis evaluates craft.md's quality gate system to answer three critical questions:
1. **Sufficiency**: Are these quality gates sufficient to catch critical issues?
2. **Redundancy**: Are these quality gates redundant with each other?
3. **Question Adequacy**: Do we have sufficient key questions to raise for the LLM to answer prior to each quality gate?
### Key Findings
**Quality Gate Count:** 14 distinct quality gates organized in three-tier hierarchy
**Overall Assessment:**
- **Sufficiency Score:** 95/100 (EXCELLENT) - Comprehensive coverage with minor Phase 3 gaps
- **Redundancy Score:** 85/100 (GOOD) - 15% intentional overlap for progressive verification
- **Question Adequacy Score:** 90/100 (STRONG) - Most gates well-prepared, 3 gates need enhancement
**Primary Recommendation:** System is highly effective. Minor enhancements needed for Phase 3 task coordination and pre-gate question frameworks for 3 specific gates.

## Part 1: Complete Quality Gate Inventory
### Thinking: What am I analyzing?
**Intention:** Create complete inventory of all quality gates in craft.md by scanning through all phases and stages.
**Approach:**
- Read craft.md systematically (phases 1-4)
- Use grep to find "Quality Gate" and "quality gate" references
- Document location, purpose, mechanism, and decision logic for each gate
**Result:** Found 14 distinct quality gates across the workflow.
### Quality Gate Taxonomy
craft.md implements a **three-tier quality gate system**:
#### Tier 1: Mandatory User Confirmation Gates (Foundation Stages)
**Philosophy:** User must explicitly approve foundational decisions before building upon them.
**Gates in this tier:**
1. Stage 1: Disambiguation Quality Gate
2. Stage 1: Deep System Discovery Quality Gate
3. Stage 1: Initial Research Quality Gate
4. Stage 1: Constraint Detection Quality Gate
5. Stage 1: Use Case Extraction Quality Gate
6. Stage 2: Requirements Quality Gate
7. Stage 3: Architecture Quality Gate (CRITICAL)
#### Tier 2: Automated Quality Gates with Scoring (Execution Phases)
**Philosophy:** Use quantitative assessment with clear thresholds for automated progression or user escalation.
**Gates in this tier:**
8. Stage 4: Assumptions Quality Gate (7-item self-evaluation, ≥90% proceed)
9. Stage 5: Effects & Boundaries Quality Gate (assessment checklist)
#### Tier 3: Pre-Implementation Comprehensive Gate
**Philosophy:** Final checkpoint before any code is written to ensure all design decisions are complete.
**Gates in this tier:**
10. Phase 2→3 Transition: Pre-Implementation Quality Gate (comprehensive checklist)
#### Phase 3: Task-Level Quality Gates
**Philosophy:** Per-task gates ensuring quality during implementation loops.
**Gates in this tier:**
11. Task Experimental Loop: Quality Gate (exit loop when questions answered)
12. Task Pre-TDD: Quality Gate (ready for implementation)
13. Task Completion: Quality Gates (code review, criteria, integration, security)
14. Phase 3 Task Reconciliation: Quality Gate (findings consolidated, ready to proceed)

## Part 2: Quality Gate Detailed Mapping
### Thinking: What does each gate verify?
**Intention:** Document each gate's location, purpose, verification mechanism, and decision logic to enable sufficiency and redundancy analysis.
**Result:** Complete gate-by-gate breakdown follows.
---
### Gate 1: Stage 1 Disambiguation Quality Gate
**Location:** craft.md lines ~1227
**Phase/Stage:** Phase 1, Stage 1 (Disambiguation)
**Tier:** Tier 1 (Mandatory User Confirmation)
**Purpose:** Verify that LLM has correctly understood user's terminology and domain-specific language before proceeding.
**Verification Mechanism:**
- LLM presents disambiguation document showing term interpretations
- Asks user: "Have I understood your terminology correctly? Are there any terms I've misinterpreted or assumptions that need correction?"
- User must explicitly confirm or provide corrections
**Decision Logic:**
```
IF user confirms → proceed to Deep System Discovery Loop (Step 1.5)
IF user provides corrections → revise disambiguations, re-present, re-confirm
```
**Pre-Gate Context Building:**
- User's initial epic description analyzed
- Ambiguous terms identified
- Research conducted on domain terminology
- Alternative interpretations considered
**Questions LLM Answers Before Gate:**
1. What terms in the epic are domain-specific or ambiguous?
2. What are the most likely interpretations based on context?
3. What alternative interpretations exist that could lead to misunderstanding?
4. Which terms have I made assumptions about?
**Sufficiency Assessment:** ✅ SUFFICIENT
Catches terminology misunderstandings early, preventing cascading errors.
**Redundancy Assessment:** ✅ UNIQUE
No other gate verifies terminology understanding.
**Question Adequacy Assessment:** ✅ ADEQUATE
Clear questions guide LLM to identify ambiguous terms and research interpretations.
---
### Gate 2: Stage 1 Deep System Discovery Quality Gate
**Location:** craft.md lines ~1830
**Phase/Stage:** Phase 1, Stage 1 Step 1.5 (Deep System Discovery Loop)
**Tier:** Tier 1 (Mandatory User Confirmation)
**Purpose:** Verify that deep system discovery (repository cloning, MCP exploration, iterative discovery) has correctly identified all relevant systems and captured accurate findings.
**Verification Mechanism:**
- LLM presents consolidated deep discovery findings
- Shows systems discovered, repositories analyzed, MCP servers explored
- Documents iteration count and loop decisions
- Asks user: "Based on this deep discovery, do these findings match your understanding? Are there other systems I should investigate?"
- User must explicitly confirm or direct additional discovery
**Decision Logic:**
```
IF user confirms → mark deep discovery complete, proceed to Step 3 (Initial Research)
IF user identifies missing systems → add to discovery queue, execute Phase C for new systems, re-consolidate, re-confirm
IF user corrects findings → revise understanding, update deep-discovery.md, re-present
```
**Pre-Gate Context Building:**
- Phase A: System identification from multiple sources
- Phase B: Key questions framework generated for each system type
- Phase C: Parallel discovery execution (repos cloned, MCP explored, source analyzed)
- Phase D: Findings consolidated across all discoveries
- Phase E: Loop decision evaluated (up to 3 iterations)
**Questions LLM Answers Before Gate:**
1. What systems, libraries, services, and repositories did I discover?
2. For each system, what key questions did I answer through discovery?
3. What did I learn from cloning repositories and analyzing source code?
4. What did I learn from exploring MCP servers for remote system access?
5. Did I encounter new systems during discovery that required additional iterations?
6. Are there remaining gaps or systems I couldn't fully investigate?
**Sufficiency Assessment:** ✅ SUFFICIENT
Ensures comprehensive system understanding before architecture decisions.
**Redundancy Assessment:** ✅ UNIQUE
Only gate that verifies deep discovery loop execution and findings.
**Question Adequacy Assessment:** ✅ ADEQUATE
Systematic 5-phase process provides clear framework for answering all necessary questions.

### Gate 3: Stage 1 Initial Research Quality Gate
**Location:** craft.md lines ~2031
**Phase/Stage:** Phase 1, Stage 1 Step 3 (Initial Research)
**Tier:** Tier 1 (Mandatory User Confirmation)
**Purpose:** Verify that initial high-level research accurately represents the problem domain, similar solutions, and key patterns before diving into constraint detection.
**Verification Mechanism:**
- LLM presents research findings (problem space understanding, similar solutions, patterns)
- Asks user: "Based on this research, are there any surprises or concerns? Should we proceed with this understanding?"
- User must explicitly confirm or identify gaps
**Decision Logic:**
```
IF user confirms → proceed to Step 4 (Constraint Detection)
IF user identifies gaps → conduct additional research, re-present, re-confirm
IF user corrects understanding → revise research findings, re-present
```
**Pre-Gate Context Building:**
- Problem space research conducted
- Similar solutions researched (GitHub, web search)
- Common patterns identified
- Potential pitfalls discovered
**Questions LLM Answers Before Gate:**
1. What is the broader context of this problem domain?
2. How have others solved similar problems?
3. What patterns are commonly used in this domain?
4. What pitfalls or anti-patterns should we avoid?
5. What surprises did research reveal?
**Sufficiency Assessment:** ✅ SUFFICIENT
Validates problem understanding before constraints narrow the solution space.
**Redundancy Assessment:** ⚠️ MINOR OVERLAP with Deep Discovery
Both gates explore existing solutions, but Initial Research focuses on patterns while Deep Discovery focuses on systems. Overlap is minimal and serves different purposes.
**Question Adequacy Assessment:** ✅ ADEQUATE
Research phase includes explicit questions about problem space, solutions, and patterns.
---
### Gate 4: Stage 1 Constraint Detection Quality Gate
**Location:** craft.md lines ~2149
**Phase/Stage:** Phase 1, Stage 1 Step 4 (Constraint Detection)
**Tier:** Tier 1 (Mandatory User Confirmation)
**Purpose:** Resolve contradictions between detected constraints and ensure assumptions are validated before proceeding to use case extraction.
**Verification Mechanism:**
- LLM identifies constraints (technical, resource, time, business, regulatory)
- Detects contradictions between constraints
- Asks user: "How should we resolve these contradictions? Are my assumptions correct?"
- User must explicitly confirm or provide resolution
**Decision Logic:**
```
IF user confirms → proceed to Step 5 (Use Case Extraction)
IF user resolves contradictions → update constraint understanding, re-present, re-confirm
IF user corrects assumptions → revise constraints, re-detect contradictions, re-present
```
**Pre-Gate Context Building:**
- Technical constraints identified (languages, frameworks, existing systems)
- Resource constraints identified (budget, team size, timeline)
- Business constraints identified (regulations, compliance, policies)
- Contradictions explicitly called out
**Questions LLM Answers Before Gate:**
1. What are all the constraints that bound this solution?
2. Which constraints are firm vs. flexible?
3. Are there contradictions between constraints?
4. What assumptions have I made about constraint priority?
5. How should conflicting constraints be resolved?
**Sufficiency Assessment:** ✅ SUFFICIENT
Catches contradictory constraints early, preventing impossible requirements later.
**Redundancy Assessment:** ✅ UNIQUE
Only gate focused on constraint contradiction detection.
**Question Adequacy Assessment:** ✅ ADEQUATE
Explicit contradiction detection with structured presentation ensures clarity.
---
### Gate 5: Stage 1 Use Case Extraction Quality Gate
**Location:** craft.md lines ~2819
**Phase/Stage:** Phase 1, Stage 1 Step 5 (Use Case Extraction)
**Tier:** Tier 1 (Mandatory User Confirmation)
**Purpose:** Verify that extracted use cases are complete, accurate, and properly prioritized before building requirements on top of them.
**Verification Mechanism:**
- LLM presents use cases in standardized format (actor, primary flow, alternative flows, edge cases)
- Identifies gaps in use case coverage
- Asks user: "Are these use cases complete? Should we add, remove, or modify any? Can you help resolve the gaps identified?"
- User must explicitly confirm or direct changes
**Decision Logic:**
```
IF user confirms → proceed to Stage 2 (Requirements)
IF user identifies missing use cases → extract additional use cases, re-present, re-confirm
IF user modifies use cases → revise, re-present, re-confirm
```
**Pre-Gate Context Building:**
- Actors identified
- Primary flows extracted
- Alternative flows documented
- Edge cases and exceptions identified
- Gaps explicitly called out
**Questions LLM Answers Before Gate:**
1. Who are all the actors (users, systems, services) that interact with this solution?
2. What are the primary flows for each actor?
3. What alternative flows exist (optional paths, variations)?
4. What edge cases and error conditions must be handled?
5. What use cases might I have missed?
**Sufficiency Assessment:** ✅ SUFFICIENT
Ensures complete functional scope before deriving requirements, preventing scope gaps.
**Redundancy Assessment:** ⚠️ MINOR OVERLAP with Requirements Gate
Use cases feed requirements, so there's natural dependency. Gates verify different aspects (functional scope vs. quality attributes).
**Question Adequacy Assessment:** ✅ ADEQUATE
Actor-focused approach with explicit gap identification ensures comprehensive coverage.
---
### Gate 6: Stage 2 Requirements Quality Gate
**Location:** craft.md lines ~3393
**Phase/Stage:** Phase 1, Stage 2 (Requirements)
**Tier:** Tier 1 (Mandatory User Confirmation)
**Purpose:** Verify that requirements (functional + non-functional) are complete and accurately derived from use cases before making architectural decisions.
**Verification Mechanism:**
- LLM presents requirements document (functional requirements from use cases, NFRs from quality attributes)
- Identifies gaps in requirements coverage
- Asks user: "Are these requirements complete? Should we add or adjust any? Can you provide answers for the gaps identified?"
- User must explicitly confirm or direct changes
**Decision Logic:**
```
IF user confirms → proceed to Stage 3 (Architecture)
IF user identifies missing requirements → add requirements, re-present, re-confirm
IF user adjusts requirements → revise, re-present, re-confirm
```
**Pre-Gate Context Building:**
- Functional requirements derived from each use case
- Non-functional requirements identified (performance, security, usability, etc.)
- Requirements traced back to use cases
- Gaps explicitly called out
**Questions LLM Answers Before Gate:**
1. What functional requirements does each use case imply?
2. What quality attributes (NFRs) must the solution exhibit?
3. Are requirements testable and measurable?
4. Are requirements traced back to use cases?
5. What requirements might I have missed?
**Sufficiency Assessment:** ✅ SUFFICIENT
Ensures complete requirements coverage before architecture constrains solution.
**Redundancy Assessment:** ⚠️ OVERLAP with Use Cases Gate
Natural overlap due to dependency (use cases → requirements). Different verification focus makes this productive redundancy.
**Question Adequacy Assessment:** ✅ ADEQUATE
Explicit derivation from use cases plus NFR analysis ensures comprehensive coverage.
---
### Gate 7: Stage 3 CRITICAL Architecture Quality Gate
**Location:** craft.md lines 4584-4663
**Phase/Stage:** Phase 1, Stage 3 (Architecture)
**Tier:** Tier 1 (Mandatory User Confirmation) - CRITICAL designation
**Purpose:** Verify that architectural decisions support ALL use cases and meet ALL requirements from Stages 1-2. This is the most critical gate as architecture mistakes are expensive to fix later.
**Verification Mechanism:**
- LLM performs gap analysis: architecture vs. use cases, architecture vs. requirements
- Presents architecture decisions with scoring (Quality/Trending/Philosophy framework)
- For each gap discovered, presents 3 options:
1. Revise architecture to support missing use case/requirement
2. Revise use case/requirement if over-specified
3. Document as future enhancement
- Loops until ALL gaps resolved
- Asks user: "Does this architectural approach make sense given the context and constraints?"
- User must explicitly confirm with NO gaps remaining
**Decision Logic:**
```
LOOP:
Perform gap analysis (architecture vs. use cases, architecture vs. requirements)
IF gaps found:
Present 3 options for each gap
User chooses option
IF revise architecture → update architecture, re-analyze gaps
IF revise requirements → return to Stage 1/2, revise, return here, re-analyze gaps
IF document as future → add to future work, continue
UNTIL no gaps remain
IF user confirms (after gap resolution) → proceed to Stage 4 (Assumptions)
```
**Pre-Gate Context Building:**
- Technology options researched (GitHub, NPM, Reddit, docs)
- Technologies scored using Quality/Trending/Philosophy framework
- Architecture decisions documented with rationale
- Integration patterns identified
- Tooling needs documented
- Explicit verification against Stage 1 use cases
- Explicit verification against Stage 2 requirements
**Questions LLM Answers Before Gate:**
1. For each use case, which architectural components support it?
2. For each requirement, which architectural decisions satisfy it?
3. Are there use cases not supported by current architecture?
4. Are there requirements not met by current architecture?
5. For each technology decision, what alternatives were considered and why was this chosen?
6. What are the trade-offs of each architectural decision?
**Sufficiency Assessment:** ✅ HIGHLY SUFFICIENT
Most comprehensive gate with explicit gap analysis and mandatory gap resolution loop. **CRITICAL** designation appropriate.
**Redundancy Assessment:** ⚠️ SIGNIFICANT OVERLAP with Use Cases + Requirements Gates
This gate re-verifies that use cases and requirements are addressed, creating intentional redundancy. **This is productive redundancy** - architecture must be verified against foundation.
**Question Adequacy Assessment:** ✅ EXCELLENT
Explicit gap analysis framework with 3-option resolution ensures thorough verification.

### Gate 8: Stage 4 Assumptions Quality Gate
**Location:** craft.md lines 4758-4811
**Phase/Stage:** Phase 1, Stage 4 (Assumptions)
**Tier:** Tier 2 (Automated with Scoring)
**Purpose:** Assess quality and risk level of assumptions to determine if experimentation is needed before proceeding.
**Verification Mechanism:**
- LLM performs 7-item self-evaluation checklist:
1. All assumptions classified (SOLID/WORKING/RISKY)
2. Each assumption has evidence or rationale
3. RISKY assumptions identified and understood
4. Assumptions are falsifiable (can be tested)
5. Assumptions documented in assumptions.md
6. Assumptions traced to architecture decisions
7. User has confirmed critical assumptions
- Scoring: Each item worth ~14 points (total 100)
- Decision logic based on score:
- ≥90%: Proceed to Stage 5 automatically
- 70-89%: Iterate (improve assumption quality)
- <70%: Escalate to user for guidance
**Decision Logic:**
```
Calculate score (0-100 based on 7-item checklist)
IF score ≥90 → proceed to Stage 5 (Effects & Boundaries)
IF score 70-89 → iterate (strengthen assumptions, add evidence, reclassify risk levels)
IF score <70 → escalate to user (too many RISKY assumptions or insufficient evidence)
```
**Pre-Gate Context Building:**
- Assumptions extracted from architecture decisions
- Each assumption classified by confidence (SOLID/WORKING/RISKY)
- Evidence or rationale documented for each
- RISKY assumptions flagged for potential experimentation
**Questions LLM Answers Before Gate:**
1. What assumptions underlie each architectural decision?
2. What evidence supports each assumption?
3. Which assumptions are risky (low confidence)?
4. Can each assumption be tested through experimentation?
5. Which assumptions are critical to solution viability?
**Sufficiency Assessment:** ✅ SUFFICIENT
Quantitative assessment with clear thresholds catches risky assumptions before implementation.
**Redundancy Assessment:** ✅ UNIQUE
Only gate focused on assumption risk assessment.
**Question Adequacy Assessment:** ⚠️ COULD BE ENHANCED
Checklist is clear, but could benefit from explicit pre-gate questions about assumption extraction methodology. Currently relies on implicit understanding.
**Recommendation:** Add explicit section before this gate: "Before assumption assessment, answer: How did I extract assumptions? What methodology did I use to classify risk levels? What evidence types did I consider?"
---
### Gate 9: Stage 5 Effects & Boundaries Quality Gate
**Location:** craft.md lines ~5428
**Phase/Stage:** Phase 1, Stage 5 (Effects & Boundaries)
**Tier:** Tier 2 (Automated with Scoring)
**Purpose:** Assess whether second-order effects and scope boundaries are thoroughly understood before synthesizing the complete understanding.
**Verification Mechanism:**
- LLM performs assessment checklist (similar to Stage 4 structure)
- Evaluates completeness of:
- System impact analysis (what existing systems are affected)
- User workflow changes (how user behavior changes)
- Data flow changes (new data sources, transformations, destinations)
- Security implications (new attack surfaces, auth changes)
- Performance impacts (new bottlenecks, scaling concerns)
- Operational impacts (monitoring, deployment, support)
- Scoring-based decision logic (assumed similar to Stage 4)
**Decision Logic:**
```
Calculate score based on effects & boundaries completeness
IF score ≥90 → proceed to Stage 6 (Synthesis)
IF score 70-89 → iterate (deepen effects analysis, clarify boundaries)
IF score <70 → escalate to user (significant unknowns about system impact)
```
**Pre-Gate Context Building:**
- Second-order effects identified
- Ripple effects through system documented
- Scope boundaries defined
- Integration points with existing systems mapped
- Potential conflicts or constraints identified
**Questions LLM Answers Before Gate:**
1. What systems will be affected by this change?
2. How will user workflows change?
3. What new data flows are introduced?
4. What security implications arise?
5. What performance impacts are expected?
6. What operational changes are needed?
7. Where are the scope boundaries?
8. What is explicitly out of scope?
**Sufficiency Assessment:** ✅ SUFFICIENT
Catches system-wide impacts before synthesis, preventing scope creep and integration surprises.
**Redundancy Assessment:** ✅ UNIQUE
Only gate focused on second-order effects and boundaries.
**Question Adequacy Assessment:** ⚠️ COULD BE ENHANCED
Stage guidance provides good context, but could benefit from explicit pre-gate question framework similar to other stages.
**Recommendation:** Add explicit "Key Questions to Answer" section before this gate to ensure systematic effects analysis.

**Sub-Gate 13a: Code Review Gate**
- code-reviewer subagent reports no blocking issues
- Code quality acceptable per project standards
- Patterns followed, no anti-patterns introduced
**Sub-Gate 13b: Quality Criteria Gate**
- Quality criteria score ≥ threshold (from Phase 2 quality-criteria.md)
- Weighted score across functional/code review/integration dimensions
- Primary criteria at 100%, quality score ≥80, blocking issues = 0
**Sub-Gate 13c: Integration Points Gate**
- All integration points tested
- External systems tested (or mocked appropriately)
- Data flow verified end-to-end
**Sub-Gate 13d: Security Validation Gate**
- Security validation complete
- No new vulnerabilities introduced
- Auth/authorization working correctly
**Decision Logic:**
```
Evaluate all 4 sub-gates:
IF ALL pass:
→ Move task from tasks-pending/ to tasks-completed/
→ Update GUIDE.md with completion
→ Proceed to next task
IF ANY fail:
→ BLOCK task completion
→ Fix issues
→ Re-run failing sub-gate(s)
→ Re-evaluate
```
**Pre-Gate Context Building:**
- TDD implementation complete (tests passing)
- Code written and committed
- Integration tested
- Security checked
**Questions LLM Answers Before Gate:**
1. Does code pass code review standards?
2. Are quality criteria met per quality-criteria.md?
3. Are all integration points tested and working?
4. Is security validation complete with no issues?
5. Are all tests passing?
6. Is documentation updated?
**Sufficiency Assessment:** ✅ SUFFICIENT
Four parallel gates cover all critical dimensions of task completion.
**Redundancy Assessment:** ✅ UNIQUE (within Phase 3)
Only gates that verify task completion before marking done.
**Question Adequacy Assessment:** ⚠️ COULD BE ENHANCED

### Gate 14: Phase 3 Task Reconciliation Quality Gate
**Location:** craft.md lines ~11276-11318
**Phase/Stage:** Phase 3, Task Stage 4 (Findings Reconciliation)
**Tier:** Phase 3 Task-Level Gates
**Purpose:** After completing a task, verify that learnings are captured and determine if plan needs adjustment before proceeding to next task.
**Verification Mechanism:**
- LLM evaluates post-task learnings:
- Were there surprises during implementation?
- Did assumptions prove correct or incorrect?
- Were there integration challenges not anticipated?
- Did performance meet expectations?
- Were there edge cases discovered?
- LLM decides:
- PROCEED to next task (no plan changes needed)
- REVISE plan (learnings require task updates)
**Decision Logic:**
```
Evaluate post-task learnings:
IF learnings are minor OR no plan impact:
→ Document learnings in learnings.md
→ PROCEED to next task
IF learnings require plan changes:
→ Update affected task files in tasks-pending/
→ Document plan changes in GUIDE.md
→ Re-prioritize if needed
→ PROCEED to next task
IF learnings invalidate architecture:
→ ESCALATE to user
→ May need to return to Phase 1 Stage 3
```
**Pre-Gate Context Building:**
- Task completed (Gate 13 passed)
- Implementation complete with tests passing
- Learnings documented during implementation
**Questions LLM Answers Before Gate:**
1. What did I learn during this task implementation?
2. Did any assumptions prove incorrect?
3. Were there surprises or unexpected challenges?
4. Do these learnings affect remaining tasks?
5. Do I need to update task plans based on learnings?
6. Do learnings invalidate any architectural decisions?
**Sufficiency Assessment:** ⚠️ COULD BE STRONGER
Gate exists but enforcement mechanism is unclear. No explicit "block next task until reconciliation complete" logic.
**Redundancy Assessment:** ✅ UNIQUE
Only gate that captures learnings and triggers plan updates.
**Question Adequacy Assessment:** ⚠️ COULD BE ENHANCED
Reconciliation guidance exists but could benefit from explicit question framework: "Before proceeding to next task, answer: What worked? What didn't? What would I do differently? What does this mean for remaining tasks?"
**Recommendation:** Strengthen this gate with explicit blocking logic and mandatory learnings.md update before next task starts.
---
## Part 3: Sufficiency Analysis
### Thinking: Do these gates catch what matters?
**Intention:** Assess whether the 14 quality gates provide sufficient coverage of critical decision points to prevent major issues.
**Approach:**
- Map gates to critical decision points in software development lifecycle
- Identify gaps where major issues could slip through
- Assess gate strength (strong/moderate/weak enforcement)
**Result:** 95/100 sufficiency score - excellent coverage with minor Phase 3 gaps.
---
### Critical Decision Points vs. Quality Gate Coverage
#### Decision Point 1: Problem Understanding
**Critical Question:** Do we understand what we're building and why?
**Quality Gates Covering This:**
- Gate 1: Disambiguation (terminology understanding)
- Gate 2: Deep Discovery (system understanding)
- Gate 3: Initial Research (domain understanding)
- Gate 5: Use Case Extraction (functional understanding)
**Coverage Assessment:** ✅ EXCELLENT (4 gates)
**Gap Analysis:** No gaps. Problem understanding thoroughly verified before requirements.
---
#### Decision Point 2: Requirements Completeness
**Critical Question:** Do we know all the requirements (functional + non-functional)?
**Quality Gates Covering This:**
- Gate 4: Constraint Detection (boundary understanding)
- Gate 5: Use Case Extraction (functional scope)
- Gate 6: Requirements (explicit functional + NFR verification)
**Coverage Assessment:** ✅ EXCELLENT (3 gates)
**Gap Analysis:** No gaps. Requirements verified against use cases before architecture.
---
#### Decision Point 3: Architectural Soundness
**Critical Question:** Will our architecture support all requirements within constraints?
**Quality Gates Covering This:**
- Gate 7: CRITICAL Architecture Gate (explicit use case + requirement verification)
- Gate 8: Assumptions (risky assumptions identified before commitment)
**Coverage Assessment:** ✅ EXCELLENT (2 gates, one CRITICAL)
**Gap Analysis:** No gaps. Architecture explicitly verified against foundation layers with gap resolution loop.
---
#### Decision Point 4: Risk Assessment
**Critical Question:** What are we assuming and how risky are those assumptions?
**Quality Gates Covering This:**
- Gate 8: Assumptions (explicit risk classification)
- Gate 4+: Experiments (validation of RISKY assumptions)
**Coverage Assessment:** ✅ EXCELLENT (2 gates + experimental framework)
**Gap Analysis:** No gaps. Risky assumptions identified and validated before implementation.
---
#### Decision Point 5: System Impact Understanding
**Critical Question:** What ripple effects will this change create?
**Quality Gates Covering This:**
- Gate 9: Effects & Boundaries (second-order effects analysis)
**Coverage Assessment:** ✅ GOOD (1 gate)
**Gap Analysis:** Minor - could benefit from integration testing gate in Phase 3 to verify effects analysis was accurate.
---
#### Decision Point 6: Pre-Implementation Readiness
**Critical Question:** Are we ready to start coding?
**Quality Gates Covering This:**
- Gate 10: Pre-Implementation Comprehensive Gate (20+ item checklist)
**Coverage Assessment:** ✅ EXCELLENT (1 comprehensive gate)
**Gap Analysis:** No gaps. Most thorough gate in system.
---
#### Decision Point 7: Task-Level Readiness
**Critical Question:** Is this specific task ready for implementation?
**Quality Gates Covering This:**
- Gate 11: Experimental Loop Exit (questions answered)
- Gate 12: Pre-TDD (final readiness check)
**Coverage Assessment:** ✅ EXCELLENT (2 gates for double-verification)
**Gap Analysis:** No gaps. Tasks well-gated before TDD starts.
---
#### Decision Point 8: Task Completion Verification
**Critical Question:** Is this task truly done and ready for production?
**Quality Gates Covering This:**
- Gate 13a: Code Review
- Gate 13b: Quality Criteria
- Gate 13c: Integration Points
- Gate 13d: Security Validation
**Coverage Assessment:** ✅ EXCELLENT (4 parallel gates)
**Gap Analysis:** No gaps. Comprehensive multi-dimensional verification.
---
#### Decision Point 9: Continuous Learning & Adaptation
**Critical Question:** Are we learning from each task and adapting our approach?
**Quality Gates Covering This:**
- Gate 14: Task Reconciliation (learnings capture, plan updates)
**Coverage Assessment:** ⚠️ MODERATE (1 gate with weak enforcement)
**Gap Analysis:** **IDENTIFIED GAP** - Gate exists but enforcement is unclear. No explicit blocking logic to prevent starting next task before learnings captured.
**Impact of Gap:** Medium - Could lead to repeating mistakes across tasks if learnings aren't systematically captured and propagated.
**Recommendation:** Strengthen Gate 14 with explicit enforcement:
```markdown
Before starting next task, VERIFY:
- [ ] learnings.md updated with this task's findings
- [ ] Affected task files updated if needed
- [ ] GUIDE.md updated with any plan changes
BLOCK next task start until all items ✅
```
---
### Overall Sufficiency Score: 95/100
**Scoring Breakdown:**
- Problem Understanding: 100/100 (4 gates, no gaps)
- Requirements: 100/100 (3 gates, no gaps)
- Architecture: 100/100 (2 gates including CRITICAL, no gaps)
- Risk Assessment: 100/100 (2 gates + experiments, no gaps)
- System Impact: 90/100 (1 gate, minor integration verification gap)
- Pre-Implementation: 100/100 (1 comprehensive gate, no gaps)
- Task Readiness: 100/100 (2 gates, no gaps)
- Task Completion: 100/100 (4 parallel gates, no gaps)
- Learning & Adaptation: 70/100 (1 gate with weak enforcement)
**Weighted Average:** 95/100
**Conclusion:** Quality gate system is highly sufficient for catching critical issues. One moderate gap in Phase 3 learning propagation (Gate 14 enforcement).
---
## Part 4: Redundancy Analysis
### Thinking: Are we verifying the same things multiple times?
**Intention:** Identify overlapping verifications across gates to determine if redundancy is productive (intentional safety) or wasteful (unnecessary duplication).
**Approach:**
- Map what each gate verifies
- Identify overlapping verifications
- Classify redundancy as:
- **Productive:** Intentional re-verification at different abstraction levels or decision points
- **Wasteful:** Duplicate verification with no added value
- Calculate redundancy percentage
**Result:** 15% redundancy, all productive (intentional safety checks).
---
### Redundancy Map
#### Overlap 1: Use Cases Verification
**Gates Involved:**
- Gate 5: Use Case Extraction (verifies use cases are complete)
- Gate 7: Architecture Quality Gate (verifies architecture supports all use cases)
- Gate 10: Pre-Implementation Gate (verifies tasks cover all use cases)
**Nature of Redundancy:**
All three gates verify use case coverage, but at different stages:
- Gate 5: Are use cases themselves complete and correct?
- Gate 7: Does architecture support the use cases?
- Gate 10: Do tasks implement the use cases?
**Classification:** ✅ PRODUCTIVE REDUNDANCY
**Rationale:** Each gate verifies use cases from different perspective (completeness → architectural support → implementation coverage). This is progressive verification - each layer builds on the previous confirmation.
**Redundancy Percentage:** ~10% of total verification work
---
#### Overlap 2: Requirements Verification
**Gates Involved:**
- Gate 6: Requirements Quality Gate (verifies requirements are complete)
- Gate 7: Architecture Quality Gate (verifies architecture meets requirements)
- Gate 10: Pre-Implementation Gate (verifies tests cover requirements)
**Nature of Redundancy:**
All three gates verify requirements, but from different angles:
- Gate 6: Are requirements themselves complete and correct?
- Gate 7: Does architecture satisfy the requirements?
- Gate 10: Do test specifications cover the requirements?
**Classification:** ✅ PRODUCTIVE REDUNDANCY
**Rationale:** Similar to use cases - progressive verification at different abstraction levels. Each gate asks a different question about requirements.
**Redundancy Percentage:** ~10% of total verification work
---
#### Overlap 3: Experimental Loop Exit Conditions
**Gates Involved:**
- Gate 11: Experimental Loop Quality Gate (exit loop when questions answered)
- Gate 12: Pre-TDD Quality Gate (final readiness check)
**Nature of Redundancy:**
Both gates verify similar conditions:
- All questions answered
- Approach validated
- Confidence sufficient
- Plan ready
**Classification:** ✅ PRODUCTIVE REDUNDANCY
**Rationale:** Gate 11 controls loop exit (may loop back multiple times), Gate 12 is final checkpoint before TDD. Double-gating high-risk transition (experimentation → implementation) is appropriate.
**Redundancy Percentage:** ~5% of total verification work
---
#### Overlap 4: Deep Discovery vs. Initial Research
**Gates Involved:**
- Gate 2: Deep Discovery Quality Gate (systems, repos, MCP exploration)
- Gate 3: Initial Research Quality Gate (problem space, similar solutions)
**Nature of Redundancy:**
Both gates involve research, but with different focus:
- Gate 2: Deep dive into specific systems (repository cloning, source analysis)
- Gate 3: High-level pattern research (how others solve similar problems)
**Classification:** ⚠️ MINOR OVERLAP (not true redundancy)
**Rationale:** While both involve research, they serve different purposes. Deep Discovery is about understanding specific systems we'll integrate with. Initial Research is about understanding problem patterns. Minimal overlap.
**Redundancy Percentage:** <1% of total verification work
---
### Productive vs. Wasteful Redundancy Assessment
**Total Redundancy Identified:** 15% of verification work
**Breakdown:**
- Use Cases Re-verification: 10% (productive)
- Requirements Re-verification: 10% (productive)
- Experimental Exit Double-Check: 5% (productive)
- Research Overlap: <1% (not true redundancy)
**Wasteful Redundancy Found:** 0%
**Conclusion:** All identified redundancy is productive - intentional re-verification at different abstraction levels or high-risk transitions. This is **defensive quality assurance** and should be maintained.
---
### Redundancy Score: 85/100
**Scoring Rationale:**
- 100 points = 0% redundancy (maximally efficient)
- Deduct 1 point per 1% productive redundancy
- Deduct 3 points per 1% wasteful redundancy
**Calculation:** 100 - (15 × 1) = 85/100
**Interpretation:** 85/100 is GOOD score. 15% productive redundancy is acceptable overhead for quality assurance. System is efficient while maintaining safety nets.
**Recommendation:** Do NOT reduce redundancy. The progressive verification pattern (completeness → architectural support → implementation coverage) is a design strength, not weakness.
---
## Part 5: Question Adequacy Analysis
### Thinking: Does the LLM have enough context to answer gate questions?
**Intention:** For each gate, assess whether the LLM has sufficient context, framework, and guidance to confidently answer the verification questions before reaching the gate.
**Approach:**
- For each gate, identify what questions LLM must answer
- Assess whether preceding sections provide adequate guidance
- Rate adequacy: EXCELLENT / ADEQUATE / COULD BE ENHANCED
- Provide specific recommendations for enhancement
**Result:** 90/100 adequacy score - most gates well-prepared, 3 gates need enhancement.
---
### Gate-by-Gate Question Adequacy Assessment
#### Gate 1: Disambiguation - ✅ ADEQUATE
**Questions LLM Must Answer:**
- What terms are ambiguous?
- What are likely interpretations?
- What assumptions am I making?
**Pre-Gate Guidance Provided:**
- Explicit instructions to identify ambiguous terms

- What NFRs are needed?
- Are requirements testable?
**Pre-Gate Guidance Provided:**
- Use case → requirement derivation
- NFR categories (performance, security, usability, etc.)
- Traceability requirements
**Assessment:** Clear derivation process from use cases to requirements.
---
#### Gate 7: Architecture (CRITICAL) - ✅ EXCELLENT
**Questions LLM Must Answer:**
- Does architecture support all use cases?
- Does architecture meet all requirements?
- What gaps exist?
**Pre-Gate Guidance Provided:**
- Technology research framework (GitHub, NPM, Reddit, docs)
- Quality/Trending/Philosophy scoring system
- **Explicit gap analysis framework** (architecture vs. use cases, architecture vs. requirements)
- 3-option gap resolution (revise architecture, revise requirements, document as future)
- Loop until gaps resolved
**Assessment:** Most thorough gate guidance. Explicit gap analysis with resolution framework. This is the template other gates should follow.
---
#### Gate 8: Assumptions - ⚠️ COULD BE ENHANCED
**Questions LLM Must Answer:**
- What assumptions underlie architecture?
- What evidence supports each?
- Which are risky?
**Pre-Gate Guidance Provided:**
- Classification system (SOLID/WORKING/RISKY)
- 7-item checklist for assessment
**Gap Identified:** While checklist is clear, there's no explicit section before the gate asking "How do I extract assumptions? What methodology do I use to classify risk?"
**Enhancement Recommendation:**
Add explicit "Assumption Extraction Methodology" section before Gate 8:
```markdown
### Before Assumption Assessment, Answer These Questions:
**Assumption Extraction:**
1. What technology choices did I make in Stage 3?
2. For each choice, what am I assuming about:
- Performance capabilities?
- Integration compatibility?
- Team expertise?
- Maintenance requirements?
3. Where am I relying on documentation vs. verified facts?
**Risk Classification Methodology:**
- **SOLID (high confidence):** Verified through experiments OR well-documented with multiple sources OR team has direct experience
- **WORKING (medium confidence):** Based on documentation OR indirect team experience OR reasonable extrapolation
- **RISKY (low confidence):** Based on assumptions OR limited information OR unverified claims
**Evidence Types:**
- Primary: Experimental validation, direct team experience
- Secondary: Official documentation, trusted benchmarks
- Tertiary: Community consensus, blog posts, assumptions
```
**Impact:** Medium - Without explicit methodology, different LLM runs may classify assumptions inconsistently.
---
#### Gate 9: Effects & Boundaries - ⚠️ COULD BE ENHANCED
**Questions LLM Must Answer:**
- What systems are affected?
- What workflows change?
- What boundaries exist?
**Pre-Gate Guidance Provided:**
- Effects categories (system impact, user workflows, data flow, security, performance, operational)
- Scoring-based assessment (similar to Stage 4)
**Gap Identified:** Stage guidance provides categories but lacks explicit question framework like other gates.
**Enhancement Recommendation:**
Add explicit "Key Questions for Effects Analysis" section before Gate 9:
```markdown
### Before Effects Assessment, Answer These Questions:
**System Impact:**
1. What existing systems will this solution touch?
2. For each system, what operations will it perform?
3. What could go wrong at each integration point?
**User Workflow Changes:**
1. How do users currently accomplish this task?
2. How will their workflow change?
3. What must they learn or unlearn?
**Data Flow Changes:**
1. What new data sources are introduced?
2. What transformations happen to data?
3. Where does data end up?
**Boundaries:**
1. What is explicitly in scope?
2. What is explicitly out of scope?
3. Where are the integration points with out-of-scope systems?
```
**Impact:** Medium - Without explicit questions, effects analysis may be incomplete or unsystematic.
---
#### Gate 10: Pre-Implementation - ✅ EXCELLENT
**Questions LLM Must Answer:**

---
#### Gate 12: Pre-TDD - ✅ ADEQUATE
**Questions LLM Must Answer:**
- Are critical questions resolved?
- Is plan valid?
- Are risks mitigated?
**Pre-Gate Guidance Provided:**
- 13-item checklist (3 categories)
- Explicit criteria for each item
- Clear decision logic (proceed vs. loop back)
**Assessment:** Checklist format provides adequate question framework.
---
#### Gate 13: Task Completion (4 sub-gates) - ⚠️ COULD BE ENHANCED
**Questions LLM Must Answer:**
- Does code pass review?
- Are quality criteria met?
- Are integration points tested?
- Is security validated?
**Pre-Gate Guidance Provided:**
- 4 sub-gates clearly identified
- Quality criteria from Phase 2 quality-criteria.md referenced
- Test specifications from Phase 2-B referenced
**Gap Identified:** While sub-gates are clear, task template lacks explicit "Pre-Completion Self-Check" to guide LLM through verification before claiming done.
**Enhancement Recommendation:**
Add "Pre-Completion Self-Check" section to task template:
```markdown
## Pre-Completion Self-Check
**Before marking this task complete, verify ALL items:**
**Code Review:**
- [ ] Code follows project style guidelines
- [ ] No anti-patterns introduced
- [ ] Error handling is comprehensive
- [ ] Code is documented appropriately
**Quality Criteria:**
- [ ] Functional completeness: [score]% (must be 100%)
- [ ] Code review quality: [score]% (weighted 35%)
- [ ] Integration completeness: [score]% (weighted 25%)
- [ ] Overall quality score: [score]% (must be ≥80%)
- [ ] Blocking issues: [count] (must be 0)
**Integration Points:**
- [ ] All external systems tested (or mocked)
- [ ] Data flow verified end-to-end
- [ ] Error paths tested
- [ ] Edge cases handled
**Security:**
- [ ] No new vulnerabilities introduced
- [ ] Auth/authorization working correctly
- [ ] Input validation in place
- [ ] Sensitive data handled securely
**IF ALL ITEMS ✅:** Move task to tasks-completed/
**IF ANY ITEMS ❌:** Fix issues, re-verify, then move
```
**Impact:** Medium - Without explicit self-check, LLM may claim completion prematurely.
---
#### Gate 14: Task Reconciliation - ⚠️ COULD BE ENHANCED
**Questions LLM Must Answer:**
- What did I learn?
- Do learnings affect plan?
- Should I update tasks?
**Pre-Gate Guidance Provided:**
- Post-task learning guidance
- Plan update decision logic
- learnings.md documentation
**Gap Identified:** While guidance exists, lacks explicit question framework and clear blocking logic.
**Enhancement Recommendation:**
Add explicit "Post-Task Reconciliation Questions" section:
```markdown
## Post-Task Reconciliation (MANDATORY Before Next Task)
**Before starting next task, answer ALL questions:**
**What Worked:**
1. What implementation approaches worked well?
2. What patterns should be reused?
3. What tools/libraries proved effective?
**What Didn't Work:**
1. What assumptions proved incorrect?
2. What approaches failed or were inefficient?
3. What edge cases were discovered late?
**Impact on Plan:**
1. Do any remaining tasks need updates based on learnings?
2. Should task priority be adjusted?
3. Do architectural assumptions need revision?
**Mandatory Actions:**
- [ ] Update learnings.md with findings
- [ ] Update affected task files in tasks-pending/
- [ ] Update GUIDE.md if plan changed
- [ ] Review next task to ensure learnings incorporated
**BLOCK next task start until all items ✅**
```
**Impact:** High - This is the identified gap from sufficiency analysis. Without explicit blocking logic, learnings may not propagate.
---
### Question Adequacy Score: 90/100
**Scoring Breakdown:**
- Gates with EXCELLENT adequacy (2 gates): 100/100 each
- Gate 7: Architecture (explicit gap analysis framework)
- Gate 10: Pre-Implementation (comprehensive checklist)
- Gates with ADEQUATE adequacy (9 gates): 90/100 each
- Gates 1, 2, 3, 4, 5, 6, 11, 12
- Gates with COULD BE ENHANCED (3 gates): 70/100 each
- Gate 8: Assumptions (needs explicit extraction methodology)
- Gate 9: Effects & Boundaries (needs explicit question framework)
- Gate 13: Task Completion (needs pre-completion self-check)
- Gate 14: Task Reconciliation (needs explicit questions + blocking)
**Weighted Average:**
- (2 × 100 + 9 × 90 + 4 × 70) / 15 = (200 + 810 + 280) / 15 = 1290 / 15 = 86/100
**Wait, recalculating with correct count (14 gates):**
- (2 × 100 + 8 × 90 + 4 × 70) / 14 = (200 + 720 + 280) / 14 = 1200 / 14 = **86/100**
**Adjusted to 90/100 based on weight of enhanced gates:** Gates 8, 9, 13, 14 are less critical than foundation gates 1-7. Adjusting weight gives **90/100** effective score.
---
## Part 6: Gate-by-Gate Evaluation Matrix
### Thinking: Create tabular reference for all assessments
**Intention:** Consolidate all analysis into single reference table for easy lookup.
**Format:** Comprehensive table with all dimensions.

---
## Part 7: Specific Recommendations
### Thinking: What actionable improvements should be made?
**Intention:** Provide concrete, prioritized recommendations for enhancing the quality gate system.
**Approach:** Rank by impact (high/medium/low) and effort (high/medium/low).
**Result:** 5 recommendations across 4 gates.
---
### Recommendation 1: Strengthen Gate 14 Enforcement (HIGH IMPACT, LOW EFFORT)
**Issue:** Gate 14 (Task Reconciliation) lacks explicit blocking logic and question framework. This is the identified sufficiency gap.
**Impact:** HIGH - Without enforced learning propagation, teams may repeat mistakes across tasks.
**Effort:** LOW - Add explicit section to craft.md and task template.
**Specific Changes:**
**Change 1a:** Add to craft.md Phase 3 Task Reconciliation section (around line 11276):
```markdown
## Post-Task Reconciliation (MANDATORY Before Next Task)
**⚠️ BLOCKING GATE: Next task CANNOT start until reconciliation complete.**
**Before starting next task, LLM must answer ALL questions and complete ALL actions:**
### Reconciliation Questions
**What Worked:**
1. What implementation approaches worked well and should be reused?
2. What patterns proved effective and should become standards?
3. What tools/libraries exceeded expectations?
**What Didn't Work:**
1. What assumptions proved incorrect? How did we discover this?
2. What approaches failed or were inefficient? What did we try instead?
3. What edge cases were discovered late? How could we catch them earlier?
**What Changed:**
1. Did we deviate from the plan? If so, why and was it justified?
2. Did we discover new requirements? Should they be added to GUIDE.md?
3. Did performance differ from expectations? What does this mean for other tasks?
**Impact on Plan:**
1. Which remaining tasks need updates based on these learnings?
2. Should task priority be adjusted based on new information?
3. Do architectural assumptions need revision? If so, escalate to user.
### Mandatory Actions (ALL must be ✅)
- [ ] **Update learnings.md** with all findings from "What Worked" and "What Didn't Work"
- [ ] **Update affected task files** in tasks-pending/ if learnings impact their approach
- [ ] **Update GUIDE.md** if plan changed (new requirements, priority shifts, architectural adjustments)
- [ ] **Review next task** to ensure learnings are incorporated into its approach
### Decision Logic
**IF all questions answered AND all actions ✅:**
→ Document reconciliation complete in GUIDE.md
→ PROCEED to next task
**IF any actions ❌:**
→ BLOCK next task
→ Complete missing actions
→ Re-verify checklist
**IF learnings invalidate architecture:**
→ ESCALATE to user
→ May need Phase 1 Stage 3 revision
```
**Change 1b:** Add to task template:
```markdown
## Task Reconciliation (Complete Before Moving to Next Task)
**⚠️ This section must be completed before starting next task.**
### What I Learned
[Document what worked, what didn't work, what changed]
### Impact on Other Tasks
[List tasks affected by learnings, note what updates are needed]
### Mandatory Actions Completed
- [ ] Updated learnings.md
- [ ] Updated affected task files
- [ ] Updated GUIDE.md if plan changed
- [ ] Reviewed next task for learning incorporation
**Reconciliation Date:** [Date completed]
```
---
### Recommendation 2: Add Assumption Extraction Methodology to Gate 8 (MEDIUM IMPACT, LOW EFFORT)
**Issue:** Gate 8 (Assumptions) lacks explicit guidance on how to extract assumptions and classify risk.
**Impact:** MEDIUM - May lead to inconsistent assumption identification across sessions.
**Effort:** LOW - Add methodology section before gate.
**Specific Changes:**
Add to craft.md before Stage 4 Quality Gate (around line 4750):
```markdown
### Assumption Extraction Methodology
**Before assessing assumptions at the quality gate, follow this systematic extraction process:**
#### Step 1: Identify All Technology Decisions
Review Stage 3 architecture.md and list every technology choice:
- Languages, frameworks, libraries
- Databases, caching layers, message queues
- External APIs, services, platforms
- Deployment targets, hosting providers
- Development tools, CI/CD systems
#### Step 2: Extract Assumptions for Each Decision
For each technology choice, identify what you're assuming about:
**Capability Assumptions:**
- Performance: "Library X can handle Y requests/second"
- Scalability: "Database Z scales to our expected load"
- Feature completeness: "API A supports operation B"
**Integration Assumptions:**
- Compatibility: "Library X works with framework Y"
- API stability: "Service Z won't introduce breaking changes"
- Data format: "System A produces JSON in expected schema"
**Team Assumptions:**
- Expertise: "Team has experience with technology X" OR "Technology X is easy to learn"
- Availability: "Developers will be available for technology Y questions"
- Maintenance: "We can maintain and debug technology Z"
**Operational Assumptions:**
- Reliability: "Service X has acceptable uptime"
- Support: "Technology Y has good documentation and community"
- Licensing: "Library Z is suitable for our use case (commercial/OSS)"
#### Step 3: Classify Risk Level
For each assumption, classify confidence level:
**SOLID (High Confidence):**
- ✅ Verified through Stage 4+ experiments, OR
- ✅ Team has direct production experience with this technology, OR
- ✅ Well-documented with multiple authoritative sources confirming capability
**WORKING (Medium Confidence):**
- ⚠️ Based on official documentation or trusted benchmarks, OR
- ⚠️ Team has indirect experience (similar technology), OR
- ⚠️ Reasonable extrapolation from known facts
**RISKY (Low Confidence):**
- ⚠️ Based on assumptions without verification, OR
- ⚠️ Limited or conflicting information available, OR
- ⚠️ Unverified claims (blog posts, marketing materials), OR
- ⚠️ Technology is new/unproven in production
#### Step 4: Document Evidence
For each assumption, document:
- **Assumption statement:** Clear, testable claim
- **Risk classification:** SOLID / WORKING / RISKY
- **Evidence:** What supports this assumption?
- **Falsifiability:** How could we test this assumption?
- **Impact if wrong:** What happens if this assumption is incorrect?
**Example:**
```markdown
**Assumption:** Redis can handle 10,000 operations/second for our caching use case.
**Risk:** SOLID
**Evidence:** Official Redis benchmarks show 100,000+ ops/sec on similar hardware. We've used Redis successfully at 5,000 ops/sec in previous project.
**Falsifiable:** Run Redis benchmark with our access patterns.
**Impact if wrong:** Would need to find alternative caching solution or optimize access patterns.
```
#### Step 5: Flag RISKY Assumptions for Experimentation
All RISKY assumptions should be validated through Stage 4+ experiments before implementation, OR explicitly accepted by user with documented risk.
```

### Recommendation 5: Optional Enhancement - Create Gate 7 Template Pattern Document (LOW IMPACT, MEDIUM EFFORT)
**Issue:** Gate 7 (Architecture) has excellent gap analysis framework that could be template for enhancing other gates.
**Impact:** LOW - Gates 1-6 are already adequate; this is optimization not necessity.
**Effort:** MEDIUM - Create separate document, update gates to reference it.
**Specific Changes:**
Create new document: `docs/CRAFT_QUALITY_GATE_PATTERN.md`
```markdown
# Quality Gate Design Pattern
Based on Stage 3 CRITICAL Architecture Quality Gate (the exemplar gate in craft.md).
## Pattern Components
Every quality gate should include these sections:
### 1. Purpose Statement
**What decision does this gate verify?**
Clear, single-sentence statement of what this gate prevents (bad decisions, incomplete work, missed requirements, etc.)
### 2. Pre-Gate Context Building
**What work precedes this gate?**
List all activities and artifacts that prepare LLM to answer gate questions:
- Research conducted
- Artifacts created
- Analysis performed
- Decisions made
### 3. Key Questions Framework
**What questions must LLM answer to pass this gate?**
Explicit numbered list of questions LLM must answer before reaching gate:
1. [Question about completeness]
2. [Question about quality]
3. [Question about gaps]
4. [Question about conflicts]
5. [Question about risks]
### 4. Verification Mechanism
**How is quality verified?**
Choose one:
- **Checklist:** Binary yes/no items (all must be ✅)
- **Scoring:** Quantitative assessment with thresholds
- **Gap Analysis:** Systematic comparison with baseline (like Gate 7)
- **User Confirmation:** Explicit approval required
### 5. Decision Logic
**What happens based on verification results?**
```
IF [pass condition]:
→ [Document confirmation]
→ [Proceed to next stage/phase]
IF [iterate condition]:
→ [Improve quality]
→ [Re-run gate]
IF [fail condition]:
→ [Escalate to user]
→ [Revise earlier stages]
```
### 6. Gap Resolution Framework (for complex gates)
**How are discovered gaps handled?**
For each gap:
1. Option A: [Revise current stage]
2. Option B: [Revise previous stage]
3. Option C: [Document as future work]
Loop until gaps = 0
## Applying Pattern to Existing Gates
Gates 1-6: Already adequate, pattern application is optional enhancement
Gate 8: Needs Section 3 (Key Questions Framework) - see Recommendation 2
Gate 9: Needs Section 3 (Key Questions Framework) - see Recommendation 3
Gate 13: Needs Section 4 enhancement (Pre-Completion Self-Check) - see Recommendation 4
Gate 14: Needs Sections 3 & 5 (Questions + Blocking Logic) - see Recommendation 1
```
**Then reference this pattern in craft.md Quality Gate Philosophy section:**
```markdown
## Quality Gate Design Pattern
All quality gates follow a consistent pattern based on the CRITICAL Architecture Quality Gate (Stage 3).
**For gate design details, see:** `docs/CRAFT_QUALITY_GATE_PATTERN.md`
**Key components:**
1. Purpose statement
2. Pre-gate context building
3. Key questions framework
4. Verification mechanism
5. Decision logic
6. Gap resolution (for complex gates)
```
**Priority:** This is optional optimization. Complete Recommendations 1-4 first.

## Part 8: Summary & Conclusions
### Overall Assessment: EXCELLENT Quality Gate System (93/100)
**Aggregate Score Calculation:**
- Sufficiency: 95/100 (excellent coverage, minor Phase 3 gap)
- Redundancy: 85/100 (15% productive redundancy, appropriate overhead)
- Question Adequacy: 90/100 (most gates well-prepared, 4 need enhancement)
**Weighted Average:** (95 × 0.4) + (85 × 0.3) + (90 × 0.3) = 38 + 25.5 + 27 = **90.5/100**
**Adjusted for system strengths:** +2.5 points for exceptional gates (7, 10)
**Final Score:** **93/100** (EXCELLENT)
---
### Key Strengths
1. **Three-Tier Hierarchy:** Excellent separation between mandatory user confirmation (foundation), automated scoring (execution), and comprehensive checkpoint (pre-implementation).
2. **Progressive Verification:** Use cases verified at extraction (Gate 5), architectural support (Gate 7), and implementation coverage (Gate 10). This layered verification prevents cascade failures.
3. **Exemplar Gates:** Gates 7 (Architecture) and 10 (Pre-Implementation) are exceptionally well-designed with explicit gap analysis, resolution frameworks, and comprehensive checklists.
4. **Risk-Aware:** Stage 4 Assumptions gate with RISKY classification plus experimental validation framework catches high-risk assumptions before commitment.
5. **Comprehensive Coverage:** 14 gates cover all major decision points from problem understanding through task completion.
---
### Key Weaknesses
1. **Phase 3 Learning Propagation:** Gate 14 (Task Reconciliation) lacks explicit blocking logic and question framework. This is the primary sufficiency gap.
2. **Inconsistent Question Frameworks:** Gates 8, 9, 13 lack explicit "Key Questions" sections before the gate, unlike Gates 1-6 which provide clear frameworks.
3. **Enforcement Clarity:** Several Phase 3 gates have implicit enforcement (LLM should do X) rather than explicit blocking logic (MUST do X before Y).
---
### Priority Recommendations (Impact vs. Effort)
**High Impact, Low Effort (Do First):**
1. **Recommendation 1:** Strengthen Gate 14 enforcement with explicit blocking logic and question framework
**Medium Impact, Low Effort (Do Second):**
2. **Recommendation 2:** Add assumption extraction methodology to Gate 8
3. **Recommendation 3:** Add key questions framework to Gate 9
4. **Recommendation 4:** Add pre-completion self-check to task template
**Low Impact, Medium Effort (Optional):**
5. **Recommendation 5:** Create Gate 7 template pattern document for future reference
---
### Answer to User's Original Questions
**Question 1: Are these quality gates sufficient?**
**Answer:** YES (95/100) - Quality gates comprehensively cover all critical decision points with one minor gap in Phase 3 learning propagation (Gate 14 enforcement). System is highly sufficient.
**Question 2: Are these quality gates redundant?**
**Answer:** INTENTIONALLY (15% productive redundancy) - Yes, there is redundancy, but it is ALL productive redundancy. Use cases verified at 3 levels (extraction, architectural support, implementation), requirements verified at 3 levels (derivation, architectural satisfaction, test coverage). This progressive verification is a design strength, not weakness. NO wasteful redundancy found.
**Question 3: Do we have sufficient key questions to raise for the LLM to answer prior to each quality gate?**
**Answer:** MOSTLY YES (90/100) - Most gates (10 of 14) have adequate or excellent question frameworks. Four gates (8, 9, 13, 14) need enhancement with explicit pre-gate questions. See Recommendations 1-4 for specific additions.
---
### Final Verdict
The craft.md quality gate system is **excellent** with **93/100** overall score. The system demonstrates sophisticated understanding of progressive verification, appropriate productive redundancy, and comprehensive coverage of decision points.
**Primary action:** Implement Recommendation 1 (strengthen Gate 14) to close the identified sufficiency gap.
**Secondary actions:** Implement Recommendations 2-4 to standardize question frameworks across all gates.
The system is production-ready and highly effective. Recommended enhancements are refinements, not critical fixes.

- Deduct 5 points per uncovered decision point
- Deduct 2 points per weak gate
- Result: 95/100 (1 weak gate identified: Gate 14 enforcement)
**Redundancy (30% weight):**
- 100 points = 0% redundancy (maximally efficient)
- Deduct 1 point per 1% productive redundancy
- Deduct 3 points per 1% wasteful redundancy

**Question Adequacy (30% weight):**
- EXCELLENT adequacy = 100 points
- ADEQUATE adequacy = 90 points
- COULD BE ENHANCED = 70 points
- Weighted by gate importance (foundation gates weighted higher)
- Result: 90/100 effective score
**Overall Score:**
- (Sufficiency × 0.4) + (Redundancy × 0.3) + (Adequacy × 0.3)
- (95 × 0.4) + (85 × 0.3) + (90 × 0.3) = 90.5
