Validation-First Authoring

Author Cuddler content so the data contract and template contract can be validated before anything is rendered.

Pattern

What validation-first authoring enforces

This pattern treats validation as the authoring finish line for each contract, not as an optional check after the fact.

1Validate the data contract

Confirm the data JSON satisfies the Data Schema.

2Validate the render contract

Check the template JSON against the Template Schema on its own.

3Confirm version alignment

Make sure the contracts and references belong to the same release family.

4Render only after both pass

Use rendering as the final output step rather than the debugging step.

The earlier the contract fails, the easier it is to explain and fix.

Validation-first authoring means the document is not considered ready until the data contract has passed and the template contract has passed.

Pattern

Validate the data JSON against the data schema.
Validate the template JSON against the template schema.
Confirm the versions are aligned.
Render only after both checks succeed.

Why It Matters

It keeps the data contract and render contract separate.
It prevents a template from hiding a bad data model.
It makes failures easier to diagnose because the failure happens earlier and in the right place.

Use This When

a document family is shared by multiple authors
output quality matters more than fast drafting
you need predictable behavior in automated pipelines

AI Safety Policy

Cuddler.dev is operated by IdeaTilt Inc. This policy explains how AI-assisted systems, generated outputs, and automation patterns associated with Cuddler.dev are expected to be used, reviewed, and constrained.

Updated: March 23, 2026

1. Purpose and Scope

Cuddler.dev publishes standards, examples, schema artifacts, embedded guidance, and implementation guidance intended to support safe and structured AI-assisted document generation. This policy applies to AI-generated or AI-assisted content, workflows, and integrations that IdeaTilt Inc. publishes through Cuddler.dev or uses to operate related services.

2. Human Accountability

AI systems may assist with drafting, transformation, classification, or rendering workflows, but people remain responsible for decisions, approvals, and public publication. IdeaTilt Inc. expects human review before relying on AI-generated outputs for legal, commercial, compliance, or operationally sensitive use cases.

3. Validation Before Use

Generated JSON and templates should be checked against the applicable schema, specification, or implementation contract before use.
Validation failures, version mismatches, or unsafe render conditions should block downstream publishing or rendering.
Examples and reusable artifacts should prefer deterministic, inspectable structures over opaque free-form output.

4. Safety Controls for Rendered Output

Untrusted content should remain subject to strict sanitization by default.
Scripts, unsafe embeds, event handlers, and non-whitelisted protocols should not be introduced through AI-generated templates or content.
Any relaxation of sanitization or external-asset controls should be deliberate, reviewable, and appropriate to the trust level of the content source.

5. Data Handling and Confidentiality

Artifact Documents are confidential by default unless explicitly designated otherwise. Users should not place confidential, regulated, or sensitive information into AI systems unless the applicable service, contract, and safeguards are appropriate for that information. Data shared with AI-assisted workflows should be limited to what is reasonably necessary for the task.

6. Prohibited or Restricted Uses

Do not use Cuddler.dev materials to misrepresent authorship, provenance, approvals, or compliance status.
Do not use AI-generated output from Cuddler.dev workflows as a substitute for legal, security, financial, or other professional advice without qualified review.
Do not use published schemas, examples, or embedded guidance to facilitate harmful, deceptive, abusive, or unlawful activity.

7. Monitoring, Correction, and Improvement
