Workflow Validator Skill

Validates JSON artifacts against validation criteria using deterministic script execution.

Automatic Validation via Hook (v0.6.0)

As of v0.6.0, the PostToolUse:Write hook automatically calls this validation script whenever an artifact is written to sandbox/*/outputs/*.json.

You typically don't need to manually invoke this skill - the hook handles it.

When to Manually Use This Skill

Use this skill only in these scenarios:

• Retrying after validation failure - when the hook blocked a write and you need to debug
• Debugging validation issues - to see detailed check results
• Checking artifacts outside the normal workflow - for ad-hoc validation
• Pre-checking before write - to validate data before writing to sandbox
