task-analyzer

name	task-analyzer
description	Performs task analysis and skill selection. Use when: determining task complexity, selecting appropriate skills, or estimating work scale.

Task Analyzer

Provides task analysis and skill selection guidance.

Skills Index

See skills-index.yaml for available skills metadata.

Task Analysis Process

1. Understand Task Essence [MANDATORY]

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 [MUST answer before proceeding]:

• 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-rules, testing
Fix	Bug resolution	ai-development-guide, testing
Refactoring	Structure improvement	coding-rules, ai-development-guide
Design	Architecture decisions	documentation-criteria, implementation-approach
Quality	Testing, review	testing, 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-rules (implementation, security)
  - testing (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	coding-rules/references/typescript.md, testing/references/typescript.md
API/Integration	integration-e2e-testing

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

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
    tags: [...]
    typical-use: <string>
    size: <small|medium|large>
    sections: [...]  # Full section list from yaml
    references: [...]  # Full reference file list from yaml when present

Note: Section and reference selection (choosing which sections or reference files are relevant) is done after reading the actual SKILL.md files. For output-format templates, read only the reference files matching the document type being created or reviewed.

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 [MANDATORY to detect]

Detect and flag these patterns IMMEDIATELY:

Pattern	Warning	REQUIRED Action
Large change at once	High risk	MUST split into phases
Implementation without tests	Quality risk	MUST follow TDD
Immediate fix on error	Root cause missed	MUST pause and analyze with 5 Whys
Coding without plan	Scope creep	MUST plan first

ENFORCEMENT: Detecting ANY warning pattern requires IMMEDIATE corrective action

Common Decision Points

Decision	Criteria
Need documentation?	Check documentation-criteria decision matrix
Which implementation approach?	Check implementation-approach phases
How to test?	Check testing + integration-e2e-testing
Code quality concerns?	Check ai-development-guide anti-patterns
Frontend specific?	Check coding-rules/references/typescript.md
