# Implementation Gap Validation
<background_information>
- **Mission**: Analyze the gap between requirements and existing codebase to inform implementation strategy
- **Success Criteria**:
- Comprehensive understanding of existing codebase patterns and components
- Clear identification of missing capabilities and integration challenges
- Multiple viable implementation approaches evaluated
- Technical research needs identified for design phase
</background_information>
<instructions>
## Core Task
Analyze implementation gap for feature **$1** based on approved requirements and existing codebase.
## Execution Steps
1. **Load Context**:
- Read `{{KIRO_DIR}}/specs/$1/spec.json` for language and metadata
- Read `{{KIRO_DIR}}/specs/$1/requirements.md` for requirements
- Core steering context: `product.md`, `tech.md`, `structure.md`
- Additional steering files only when directly relevant to the feature's domain rules, integrations, runtime prerequisites, compliance/security constraints, or existing product boundaries
- Relevant local agent skills or playbooks only when they clearly match the feature's host environment or use case and provide analysis-relevant context
2. **Read Analysis Guidelines**:
- Read `rules/gap-analysis.md` from this skill's directory for comprehensive analysis framework
#### Parallel Research
The following research areas are independent and can be executed in parallel:
1. **Codebase analysis**: Existing implementations, architecture patterns, integration points, extension possibilities
2. **External dependency research**: Dependency compatibility, version constraints, known integration challenges (when needed)
3. **Context loading**: Requirements, core steering, task-relevant extra steering, relevant local agent skills/playbooks, and gap-analysis rules
If multi-agent is enabled, spawn sub-agents for each area above. Otherwise execute sequentially.
After all parallel research completes, synthesize findings for gap analysis.
3. **Execute Gap Analysis**:
- Follow gap-analysis.md framework for thorough investigation
- Analyze existing codebase using Grep and Read tools
- Use WebSearch/WebFetch for external dependency research if needed
- Evaluate multiple implementation approaches (extend/new/hybrid)
- Use language specified in spec.json for output
4. **Generate Analysis Document**:
- Create comprehensive gap analysis following the output guidelines in gap-analysis.md
- Present multiple viable options with trade-offs
- Flag areas requiring further research
5. **Write Gap Analysis to Disk**:
**Write the gap analysis to disk so it survives session boundaries and can be referenced during design phase.**
- Save the gap analysis to `{{KIRO_DIR}}/specs/$1/research.md`
- If the file already exists, append the new analysis (separated by a horizontal rule `---`) rather than overwriting previous research
- Verify the file was written by reading it back
## Important Constraints
- **Information over Decisions**: Provide analysis and options, not final implementation choices
- **Multiple Options**: Present viable alternatives when applicable
- **Thorough Investigation**: Use tools to deeply understand existing codebase
- **Explicit Gaps**: Clearly flag areas needing research or investigation
- **Context Discipline**: Start with core steering and expand only with analysis-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 analysis
- **Grep extensively**: Search codebase for patterns, conventions, and integration points
- **WebSearch/WebFetch**: Research external dependencies and best practices when needed
- **Write last**: Generate analysis only after complete investigation
## Output Description
Provide output in the language specified in spec.json with:
1. **Analysis Summary**: Brief overview (3-5 bullets) of scope, challenges, and recommendations
2. **Document Status**: Confirm analysis approach used
3. **Next Steps**: Guide user on proceeding to design phase
**Format Requirements**:
- Use Markdown headings for clarity
- Keep summary concise (under 300 words)
- Detailed analysis follows gap-analysis.md output guidelines
## Safety & Fallback
### Error Scenarios
- **Missing Requirements**: If requirements.md doesn't exist, stop with message: "Run `/kiro-spec-requirements $1` first to generate requirements"
- **Requirements Not Approved**: If requirements not approved, warn user but proceed (gap analysis can inform requirement revisions)
- **Empty Steering Directory**: Warn user that project context is missing and may affect analysis quality
- **Complex Integration Unclear**: Flag for comprehensive research in design phase rather than blocking
- **Language Undefined**: Default to English (`en`) if spec.json doesn't specify language
### Next Phase: Design Generation
**If Gap Analysis Complete**:
- Review gap analysis insights
- Run `/kiro-spec-design $1` to create technical design document
- Or `/kiro-spec-design $1 -y` to auto-approve requirements and proceed directly
**Note**: Gap analysis is optional but recommended for brownfield projects to inform design decisions.

Install the "kiro-validate-gap" agent skill from https://github.com/gotalab/cc-sdd/tree/main/tools/cc-sdd/templates/agents/antigravity-skills/skills/kiro-validate-gap. Read its SKILL.md or equivalent instructions first, install only the files needed for this workspace, and summarize any required setup before using it.
