Skill Eval Runner

Analizza e verifica la qualità delle skill tramite i file evals/.

Overview

Esegue il ciclo RED-GREEN-REFACTOR adattato alle skill:

RED: verifica che la skill risolva un problema reale
GREEN: conferma che trigger e output siano corretti
REFACTOR: suggerisce miglioramenti basati sui test

Process

Step 1: Locate Evals

ls .Claude/skill/{skill-name}/evals/

Cerca: trigger_evals.json, evals.json

Step 2: Validate Trigger Accuracy

Leggi trigger_evals.json e verifica:

Le query in should_trigger matchano la description della skill?
Le query in should_not_trigger sono sufficientemente diverse?
Ci sono abbastanza test cases? (minimo 5 per should_trigger)

Report:

Trigger Analysis for {skill-name}:
✅ should_trigger: {n} cases — coverage seems adequate
⚠️  should_not_trigger: {n} cases — consider adding more negative cases

Step 3: Validate Quality Evals

Leggi evals.json e verifica:

I test cases coprono i casi d'uso principali?
Gli expected_output_contains sono realistici?
Ci sono test per edge cases?

Step 4: Run Script Validation

Se la skill ha scripts/:

bash .Claude/scripts/run_evals.sh 2>&1

Step 5: Generate Report

SKILL EVAL REPORT: {skill-name}
================================
Trigger evals: {n} should_trigger, {m} should_not_trigger
Quality evals: {n} test cases
Scripts: {present/absent}

Examples

Example 1: Testare skill brainstorming

/skill-eval brainstorming
→ Legge .Claude/skill/brainstorming/evals/
→ Analizza trigger_evals.json: 7 should_trigger, 4 should_not_trigger
→ Analizza evals.json: 3 test cases
→ Report: PASS — coverage adeguata

Example 2: Nuova skill appena creata

/skill-eval my-new-skill
→ Legge .Claude/skill/my-new-skill/evals/
→ Trova solo 2 trigger cases
→ Report: NEEDS_IMPROVEMENT — aggiungere almeno 3 trigger cases
→ Suggerisce: "Add these trigger phrases: ..."

Troubleshooting

evals/ directory non trovata

Causa: La skill non ha ancora evals Soluzione: Usa skill-creator per aggiungere evals, oppure copia dal template in skill-template-2.0/evals/

JSON syntax error in evals file

Causa: Trailing comma o caratteri speciali Soluzione: Valida con python3 -m json.tool {file}
