SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

Validation is essential to ensure outputs meet criteria; this skill runs deterministic checks to confirm artifacts before workflow completion.

Core Features & Use Cases

Reads validation.json for current sandbox step criteria
Executes deterministic validation logic
Returns detailed pass/fail results to drive retries or progression

Quick Start

Manually run the validation script: bun .claude/skills/workflow-validator/scripts/validate.ts <artifact> '<criteria>'.

FAQPage Schema

How do I validate JSON artifacts against criteria in my workflow?▼

Validation checks JSON artifacts against predefined criteria using deterministic logic. Run the validate script with your artifact and criteria to get a pass/fail result with per-check messages, enabling you to confirm outputs meet requirements before workflow completion.

Can I validate artifacts without consuming tokens?▼

Yes. The workflow-validator runs deterministic validation logic locally without token consumption, making it efficient for repeated validation during retries, debugging, or ad-hoc checks outside your normal workflow.

What does the validation script return?▼

The validation script returns detailed pass/fail results for each check performed against your artifact. These per-check messages guide you on what passed or failed, letting you update validation state and decide next workflow steps.

How do I debug validation failures?▼

Run the validation script manually against your artifact and criteria to see detailed per-check messages identifying which validations failed. This lets you diagnose issues and retry after making corrections.

Does workflow validation work with any artifact format?▼

Validation reads JSON artifacts and sandbox validation criteria from validation.json. Your artifacts must be JSON-compatible and your criteria must be defined in the validation.json file for the deterministic checks to execute.

When should I use validation outside the normal workflow?▼

Use ad-hoc validation when you're debugging validation issues, testing criteria changes, or confirming artifacts meet requirements before committing them. The token-free validation makes testing criteria iterations fast and cost-effective.
