tomevault-io Task Analyzer
Provides metacognitive task analysis and skill selection guidance.
Skills Index
Skills Index Reference
Load skills metadata from the project-local skills-index.yaml for tag-based matching. Use the tags field to match against task keywords and the typical_use field to validate relevance.
The skills-index.yaml is a project-local file maintained by the /sync-skills command at .claude/skills/task-analyzer/references/skills-index.yaml. It is NOT inside the plugin — each project maintains its own copy.
A default template is bundled with the plugin at skills-index.yaml as a starting point. Run /sync-skills to generate or update the local version.
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 |
Key Questions:
- What problem are we really solving?
- What is the expected outcome?
- What could go wrong if we approach this superficially?
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:
- Larger scale → process/documentation skills more important
- Smaller scale → implementation skills more focused
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 the project-local 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, typescript-testing |
| API/Integration | integration-e2e-testing |
Output Format
Return structured analysis with skill metadata from the project-local 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 at once | High risk | Split into phases |
| Implementation without tests | Quality risk | Follow TDD |
| Immediate fix on error | Root cause missed | Pause, analyze |
| Coding without plan | Scope creep | Plan first |
