# Skill Validation Report: subagent-teams

**Rating**: **Good**
**Overall Score**: **84/100**

## Summary

The `subagent-teams` skill is a well-structured Automation skill with strong procedural workflows, excellent domain expertise in references, and clear anti-patterns. It has minor gaps in user interaction (limited clarification questions), lacks external documentation links (domain is internal to Claude Code), and the description style could be improved slightly. Overall, it is functional and ready for use with minor improvements.

## Critical Issues

None. The skill is functional and well-structured.

## Improvement Recommendations

1. **High Priority**: Add explicit `Required Clarifications` section with 2-3 concrete questions:
   ```markdown
   ## Required Clarifications
   1. **Task scope**: "What is the complete scope of work?"
   2. **Constraints**: "Any files/areas that should NOT be modified?"
   3. **Priority**: "Which subtask results are most critical?"
   ```

2. **Medium Priority**: Add a brief "Output Format" specification for synthesized results:
   ```markdown
   ## Synthesized Output Format
   After all subagents complete, deliver:
   - Summary of findings/changes per subtask
   - Any conflicts or gaps identified
   - Recommended next steps (if iterative)
   ```

3. **Low Priority**: Add external documentation links where applicable (Anthropic Claude Code docs, Task tool reference).

## Strengths

- Excellent workflow structure (5 phases with clear gates)
- Comprehensive anti-patterns table with corrections
- Strong reference files covering delegation patterns, prompts, and context management
- Good model selection strategy with cost optimization
- High reusability — works across any domain or task type
- Clear "Does/Does NOT" scope definition
- Practical sizing guide for team composition
