faf-format-validator

This skill checks that the SKILL.md frontmatter contains required YAML fields like name, description, and allowed-tools, and verifies the Markdown body has properly structured activation instructions.

The correct project.faf YAML structure requires the format, project, and architecture fields to ensure IANA compliance and reliable AI context. This validation skill checks that your project.faf file contains these mandatory structural sections.

Mixing SKILL.md and project.faf formats causes errors because each YAML format has distinct structural requirements for its specific use case. This skill detects mixed-format errors and guides you to correct the format choice and migrate properly.

You can check your YAML frontmatter by validating the SKILL.md file structure, ensuring the name, description, and allowed-tools fields are correctly formatted and the Markdown body contains properly structured activation instructions.

When project.faf validation fails IANA compliance, this skill identifies the missing or malformed format, project, or architecture sections and reports the errors so you can fix the YAML structure for reliable AI context.

Yes, this skill validates both distinct YAML formats in the FAF ecosystem. It checks SKILL.md frontmatter for Claude Code skills and project.faf for universal project DNA, while detecting and reporting any mixed-format errors.
