Identify and validate skills that declare boolean-based invocability, ensuring the frontmatter includes a valid 'name' and 'description' while flagging non-boolean or ambiguous invocable indicators.

Core Features & Use Cases

Validates presence of essential metadata (name, description) in SKILL.md.
Detects and flags non-boolean or ambiguous invocable values in frontmatter.
Useful for QA pipelines that verify skill definitions before activation in a larger automation system.

FAQPage Schema

How do I validate the boolean invocability flag in SKILL.md frontmatter?▼

To validate the boolean invocability flag in SKILL.md frontmatter, check that the metadata includes a valid name and description while flagging any non-boolean or ambiguous invocable values.

What happens when frontmatter contains a non-boolean invocable value in skill fixtures?▼

When frontmatter contains a non-boolean or ambiguous invocable value in skill fixtures, the validation fails and flags the issue, ensuring only proper boolean values are accepted for invocability.

How do I check that required metadata like name and description exists in SKILL.md?▼

To check that required metadata like name and description exists in SKILL.md, validate the frontmatter to confirm the presence of these essential fields before processing the invocability flag.

Can I use frontmatter validation for skill fixtures in QA pipelines?▼

Yes, you can use frontmatter validation for skill fixtures in QA pipelines to verify skill definitions, detect misformatted invocability, and ensure required metadata exists before activating them in larger automation systems.

Why does my skill metadata validation fail on ambiguous invocable indicators?▼

Skill metadata validation fails on ambiguous invocable indicators because the invocability flag must be a proper boolean value; any non-boolean representation triggers a failure to prevent misformatted metadata.
