Task Analyzer

Provides metacognitive task analysis and skill selection guidance.

Skills Index

See [skills-index.yaml](references/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

1. Essential - Directly related to task type
2. Quality - Testing and quality assurance
3. Process - Workflow and documentation
4. 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 |
