Running Skills Edd Cycle

Running Skills EDD Cycle

Run evaluation-driven development cycle for agent skills.

Workflow

Step 1: Build Evaluations First

Create evaluations BEFORE writing documentation. This ensures skills solve real problems.

1. Run Claude on representative tasks WITHOUT the skill
2. Document specific failures or missing context
3. Create 3+ evaluation scenarios that test these gaps

Evaluation scenarios are saved to tests/scenarios.md as the final step of /creating-effective-skills workflow.

Step 2: Establish Baseline

Measure Claude's performance WITHOUT the skill:

1. Run each evaluation scenario
2. Record: success/failure, missing context, wrong approaches
3. This becomes comparison baseline

Step 3: Write Minimal Instructions

Create just enough content to address the gaps:

• Start with core workflow only
• Add detail only when tests fail
• Avoid over-explaining

REQUIRED: Use the Skill tool to invoke creating-effective-skills before writing any skill content. This ensures proper naming, description format, and structure from the start.

Step 4: Evaluate with Multiple Models

Note: This step requires Claude Code CLI. Skip if using Claude.ai.

REQUIRED: Use the Skill tool to invoke evaluating-skills-with-models with the skill path.

This will:

1. Auto-load scenarios from tests/scenarios.md
2. Execute with sub-agents across models (sonnet, opus, haiku)
3. Evaluate against expected behaviors
4. Determine recommended model (least capable with full compatibility)

After evaluation: Document recommended model in skill's metadata.

REQUIRED: Use the Skill tool to invoke improving-skills when observations reveal issues.

Step 5: Final Review

Before considering the skill complete:

REQUIRED: Use the Skill tool to invoke reviewing-skills to verify compliance with best practices.

1. Address all compliance issues identified
2. Re-run evaluations after fixes
3. Repeat until skill passes review

Step 6: User Validation Guide

After all reviews pass, output instructions for user to validate in a fresh session:

## Test Your Skill

Run this command in a new terminal to test with a fresh Claude session:

claude --model {recommended_model} "{evaluation_query}"

After testing, paste the output file or result back to this session for final confirmation.

Replace:

• {recommended_model}: Model determined in Step 4 (e.g., sonnet)
• {evaluation_query}: A representative query from your evaluations

Quick Reference

Cycle

Identify gaps -> Create evaluations -> Baseline -> Write minimal -> Model eval (sub-agents) -> Review -> User validation
