Quality Gates

Per-phase quality gate criteria and scoring dimensions for spec-generator outputs.

When to Use

Phase	Usage	Section
Phase 2-5	Post-generation self-check	Per-Phase Gates
Phase 6	Cross-document validation	Cross-Document Validation
Phase 6	Final scoring	Scoring Dimensions

---

Quality Thresholds

Gate	Score	Action
Pass	>= 80%	Continue to next phase
Review	60-79%	Log warnings, continue with caveats
Fail	< 60%	Must address issues before continuing

In auto mode (-y), Review-level issues are logged but do not block progress.

Scoring Dimensions

1. Completeness (25%)

All required sections present with substantive content.

Score	Criteria
100%	All template sections filled with detailed content
75%	All sections present, some lack detail
50%	Major sections present but minor sections missing
25%	Multiple major sections missing or empty
0%	Document is a skeleton only

2. Consistency (25%)

Terminology, formatting, and references are uniform across documents.

Score	Criteria
100%	All terms consistent, all references valid, formatting uniform
75%	Minor terminology variations, all references valid
50%	Some inconsistent terms, 1-2 broken references
25%	Frequent inconsistencies, multiple broken references
0%	Documents contradict each other

3. Traceability (25%)

Requirements, architecture decisions, and stories trace back to goals.

Score	Criteria
100%	Every story traces to a requirement, every requirement traces to a goal
75%	Most items traceable, few orphans
50%	Partial traceability, some disconnected items
25%	Weak traceability, many orphan items
0%	No traceability between documents

4. Depth (25%)

Content provides sufficient detail for execution teams.

Score	Criteria
100%	Acceptance criteria specific and testable, architecture decisions justified, stories estimable
75%	Most items detailed enough, few vague areas
50%	Mix of detailed and vague content
25%	Mostly high-level, lacking actionable detail
0%	Too abstract for execution

Per-Phase Quality Gates

Phase 1: Discovery

Problem statement	Specific and measurable	Error
Target users	>= 1 persona with needs described	Error
Goals defined	>= 2 measurable goals	Error
Success metrics	>= 2 quantifiable metrics	Warning

Multi-perspective	>= 2 CLI perspectives synthesized	Info

Phase 3: Requirements (PRD)

Check	Criteria	Severity
Functional requirements	>= 3 with REQ-NNN IDs	Error
Acceptance criteria	Every requirement has >= 1 criterion	Error
MoSCoW priority	Every requirement tagged	Error
Non-functional requirements	>= 1 (performance, security, etc.)	Warning
User stories	>= 1 per Must-have requirement	Warning
Traceability	Requirements trace to product brief goals	Warning

Phase 4: Architecture

Check	Criteria	Severity
Component diagram	Present (Mermaid or ASCII)	Error
Tech stack specified	Languages, frameworks, key libraries	Error
ADR present	>= 1 Architecture Decision Record	Error
ADR has alternatives	Each ADR lists >= 2 options considered	Warning
Integration points	External systems/APIs identified	Warning
Data model	Key entities and relationships described	Warning
Codebase mapping	Mapped to existing code (if has_codebase)	Info

Phase 5: Epics & Stories

Check	Criteria	Severity
Epics defined	3-7 epics with EPIC-NNN IDs	Error
MVP subset	>= 1 epic tagged as MVP	Error
Stories per epic	2-5 stories per epic	Error
Story format	"As a...I want...So that..." pattern	Warning
Dependency map	Cross-epic dependencies documented	Warning
Estimation hints	Relative sizing (S/M/L/XL) per story	Info
Traceability	Stories trace to requirements	Warning

Phase 6: Readiness Check

Check	Criteria	Severity
All documents exist	product-brief, requirements, architecture, epics	Error
Frontmatter valid	All YAML frontmatter parseable and correct	Error
Cross-references valid	All document links resolve	Error
Overall score >= 60%	Weighted average across 4 dimensions	Error
No unresolved Errors	All Error-severity issues addressed	Error
Summary generated	spec-summary.md created	Warning

---

Cross-Document Validation

Checks performed during Phase 6 across all documents:

Completeness Matrix

Product Brief goals  ->  Requirements (each goal has >= 1 requirement)
Requirements         ->  Architecture (each Must requirement has design coverage)
Requirements         ->  Epics (each Must requirement appears in >= 1 story)
Architecture ADRs    ->  Epics (tech choices reflected in implementation stories)

Consistency Checks

Check	Documents	Rule
Terminology	All	Same term used consistently (no synonyms for same concept)
User personas	Brief + PRD + Epics	Same user names/roles throughout
Scope	Brief + PRD	PRD scope does not exceed brief scope
Tech stack	Architecture + Epics	Stories reference correct technologies

Traceability Matrix Format

| Goal | Requirements | Architecture | Epics |
|------|-------------|--------------|-------|
| G-001: ... | REQ-001, REQ-002 | ADR-001 | EPIC-001 |
| G-002: ... | REQ-003 | ADR-002 | EPIC-002, EPIC-003 |

Issue Classification

Error (Must Fix)

• Missing required document or section
• Broken cross-references
• Contradictory information between documents
• Empty acceptance criteria on Must-have requirements
• No MVP subset defined in epics

Warning (Should Fix)

• Vague acceptance criteria
• Missing non-functional requirements
• No success metrics defined
• Incomplete traceability
• Missing architecture review notes

Info (Nice to Have)

• Could add more detailed personas
• Consider additional ADR alternatives
• Story estimation hints missing
• Mermaid diagrams could be more detailed
