Task Analyzer
Provides metacognitive task analysis and skill selection guidance.
Skills Index
See skills-index.yaml for available skills metadata.
Task Analysis Process
1. Understand Task Essence
Identify the fundamental purpose beyond surface-level work:
| Surface Work | Fundamental Purpose | |--------------|---------------------| | "Fix this bug" | Problem solving, root cause analysis | | "Implement this feature" | Feature addition, value delivery | | "Refactor this code" | Quality improvement, maintainability | | "Update this file" | Change management, consistency |
Action: Map the user request to one row in the Surface Work → Fundamental Purpose table above. If no row matches, state the fundamental purpose explicitly before proceeding.
2. Estimate Task Scale
| Scale | File Count | Indicators | |-------|------------|------------| | Small | 1-2 | Single function/component change | | Medium | 3-5 | Multiple related components | | Large | 6+ | Cross-cutting concerns, architecture impact |
Scale affects skill priority:
- Scale >= Large → include documentation-criteria and implementation-approach in selectedSkills with priority high
- Scale = Small → limit selectedSkills to task-type essential skills only (max 3)
3. Identify Task Type
| Type | Characteristics | Key Skills | |------|-----------------|------------| | Implementation | New code, features | coding-principles, testing-principles | | Fix | Bug resolution | ai-development-guide, testing-principles | | Refactoring | Structure improvement | coding-principles, ai-development-guide | | Design | Architecture decisions | documentation-criteria, implementation-approach | | Quality | Testing, review | testing-principles, integration-e2e-testing |
4. Tag-Based Skill Matching
Extract relevant tags from task description and match against skills-index.yaml:
Task: "Implement user authentication with tests"
Extracted tags: [implementation, testing, security]
Matched skills:
- coding-principles (implementation, security)
- testing-principles (testing)
- ai-development-guide (implementation)
5. Implicit Relationships
Consider hidden dependencies:
| Task Involves | Also Include | |---------------|--------------| | Error handling | debugging, testing | | New features | design, implementation, documentation | | Performance | profiling, optimization, testing | | Frontend | typescript-rules, test-implement | | API/Integration | integration-e2e-testing |
Output Format
Return structured analysis with skill metadata from skills-index.yaml:
taskAnalysis:
essence: <string> # Fundamental purpose identified
type: <implementation|fix|refactoring|design|quality>
scale: <small|medium|large>
estimatedFiles: <number>
tags: [<string>, ...] # Extracted from task description
selectedSkills:
- skill: <skill-name> # From skills-index.yaml
priority: <high|medium|low>
reason: <string> # Why this skill was selected
# Pass through metadata from skills-index.yaml
tags: [...]
typical-use: <string>
size: <small|medium|large>
sections: [...] # All sections from yaml, unfiltered
Note: Section selection (choosing which sections are relevant) is done after reading the actual SKILL.md files.
Skill Selection Priority
- Essential - Directly related to task type
- Quality - Testing and quality assurance
- Process - Workflow and documentation
- Supplementary - Reference and best practices
Metacognitive Question Design
Generate 3-5 questions according to task nature:
| Task Type | Question Focus | |-----------|----------------| | Implementation | Design validity, edge cases, performance | | Fix | Root cause (5 Whys), impact scope, regression testing | | Refactoring | Current problems, target state, phased plan | | Design | Requirement clarity, future extensibility, trade-offs |
Warning Patterns
Detect and flag these patterns:
| Pattern | Warning | Mitigation | |---------|---------|------------| | Large change detected | Pair with implementation-approach | Split into phases per strategy | | Implementation task detected | Pair with testing-principles | Apply TDD from start | | Error fix requested | Pair with ai-development-guide | Apply 5 Whys before fixing | | Multi-file task without plan | Pair with documentation-criteria | Create work plan first |
