SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It prevents failed or unverifiable actions from silently passing by programmatically checking that a submitted artifact, truth claims, and wiring are actually satisfied.

Core Features & Use Cases

  • Success-criteria verification: Reads the Plan’s declared Truths and ensures each one is testable and observed.
  • Artifact and link probing: Confirms expected artifacts exist, verifies linked URLs resolve, and checks message/content where applicable.
  • Non-blocking fallback behavior: When probes cannot be run, records an explicit fail reason so the retrying draft stage can address the gap.

Quick Start

Run validate for the action’s current stage to automatically check the Plan’s truths, artifacts, and key link wiring and record pass or fail evidence.

FAQPage Schema
How do I verify action plan success criteria without manual operator contact?

Verify action plan success criteria by programmatically probing declared Truths, checking artifact existence, resolving linked URLs, and emitting pass or fail decisions. This validation process ensures intended outcomes are actually met without requiring manual operator contact.

What is plan validation and how does artifact probing work?

Plan validation is the process of mapping declared Truths to programmatic probes to confirm artifact existence, verify content, and check URL link resolution. It determines whether an action's intended outcome is actually met by testing assertions against observed evidence.

How do I validate URLs and check if linked artifacts exist in an action plan?

Validate URLs and check linked artifacts by applying programmatic probes during the validate stage. The system confirms artifact existence, verifies linked URLs resolve correctly, and checks message content to ensure submitted artifacts satisfy declared Truths.

What happens when a validation probe cannot be run or fails to verify a truth claim?

When validation probes cannot be run, the system records an explicit fail reason through non-blocking fallback behavior. This allows the retrying draft stage to address the gap and prevents failed or unverifiable actions from silently passing validation.

Can I use a default fallback recipe for playbook validation when no specific skill exists?

Yes, you can use the default fallback recipe to validate actions with any plan shape when no playbook-specific validation skill exists. The fallback applies programmatic probes to artifact assertions and key link wiring to verify intended outcomes.

Why do unverifiable actions silently pass and how can approval gating prevent it?

Unverifiable actions silently pass when truth claims and wiring are not programmatically checked. Approval gating prevents this by probing artifacts, assertions, and key link wiring during validation, recording explicit fail evidence for gaps so the retrying draft stage can address them.
