# Technical Design Validation

<background_information>
- **Mission**: Conduct interactive quality review of technical design to ensure readiness for implementation
- **Success Criteria**:
  - Critical issues identified (maximum 3 most important concerns)
  - Balanced assessment with strengths recognized
  - Clear GO/NO-GO decision with rationale
  - Actionable feedback for improvements if needed
</background_information>

<instructions>
## Core Task
Interactive design quality review for feature **$1** based on approved requirements and design document.

## Execution Steps

1. **Gather Context**:
   - Read `{{KIRO_DIR}}/specs/$1/spec.json` for language and metadata
   - Read `{{KIRO_DIR}}/specs/$1/requirements.md` for requirements
   - Read `{{KIRO_DIR}}/specs/$1/design.md` for design document
   - Core steering context: `product.md`, `tech.md`, `structure.md`
   - Additional steering files only when directly relevant to architecture boundaries, integrations, runtime prerequisites, domain rules, security/performance constraints, or team conventions that affect implementation readiness
   - Relevant local agent skills or playbooks only when they clearly match the feature's host environment or use case and provide review-relevant context

#### Parallel Research

The following research areas are independent and can be executed in parallel:
1. **Context & rules loading**: Spec documents, core steering, task-relevant extra steering, relevant local agent skills/playbooks, and `rules/design-review.md` from this skill's directory for review criteria
2. **Codebase pattern survey**: Gather existing architecture patterns, naming conventions, and component structure from the codebase to use as reference during review

If multi-agent is enabled, spawn sub-agents for each area above. Otherwise execute sequentially.

After all parallel research completes, synthesize findings for review.

2. **Execute Design Review**:
   - Reference conversation history when available: leverage prior requirements discussion and user's stated design intent
   - Follow design-review.md process: Analysis → Critical Issues → Strengths → GO/NO-GO
   - Limit to 3 most important concerns
   - Engage interactively with user — ask clarifying questions, propose alternatives
   - Use language specified in spec.json for output

3. **Decision and Next Steps**:
   - Clear GO/NO-GO decision with rationale
   - Provide specific actionable next steps (see Next Phase below)

## Important Constraints
- **Quality assurance, not perfection seeking**: Accept acceptable risk
- **Critical focus only**: Maximum 3 issues, only those significantly impacting success
- **Conversation-aware**: Leverage discussion history for requirements context and user intent when available
- **Interactive approach**: Engage in dialogue, ask clarifying questions, propose alternatives
- **Balanced assessment**: Recognize both strengths and weaknesses
- **Actionable feedback**: All suggestions must be implementable
- **Context Discipline**: Start with core steering and expand only with review-relevant steering or use-case-aligned local agent skills/playbooks
</instructions>

## Tool Guidance
- **Read first**: Load spec, core steering, relevant local playbooks/agent skills, and rules before review
- **Grep if needed**: Search codebase for pattern validation or integration checks
- **Interactive**: Engage with user throughout the review process

## Output Description
Provide output in the language specified in spec.json with:

1. **Review Summary**: Brief overview (2-3 sentences) of design quality and readiness
2. **Critical Issues**: Maximum 3, following design-review.md format
3. **Design Strengths**: 1-2 positive aspects
4. **Final Assessment**: GO/NO-GO decision with rationale and next steps

**Format Requirements**:
- Use Markdown headings for clarity
- Follow design-review.md output format
- Keep summary concise

## Safety & Fallback

### Error Scenarios
- **Missing Design**: If design.md doesn't exist, stop with message: "Run `/kiro-spec-design $1` first to generate design document"
- **Design Not Generated**: If design phase not marked as generated in spec.json, warn but proceed with review
- **Empty Steering Directory**: Warn user that project context is missing and may affect review quality
- **Language Undefined**: Default to English (`en`) if spec.json doesn't specify language

### Next Phase: Task Generation

**If Design Passes Validation (GO Decision)**:
- Review feedback and apply changes if needed
- Run `/kiro-spec-tasks $1` to generate implementation tasks
- Or `/kiro-spec-tasks $1 -y` to auto-approve and proceed directly

**If Design Needs Revision (NO-GO Decision)**:
- Address critical issues identified
- Re-run `/kiro-spec-design $1` with improvements
- Re-validate with `/kiro-validate-design $1`

**Note**: Design validation is recommended but optional. Quality review helps catch issues early.
