skill-creator

Brynhild skills require minimal frontmatter (name and description) in a SKILL.md file kept under 500 lines. Create a skill directory, add frontmatter at the top, write concise body content, then optionally organize references/, scripts/, and assets/ subdirectories for supporting materials.

Frontmatter is structured metadata (name, description) at the top of SKILL.md that enables discovery and routing. Body content is the skill's actual logic and guidance, kept concise to encourage progressive disclosure and clarity rather than monolithic documentation.

The skill-creator enforces a minimal frontmatter schema with only name and description to prevent system mutation and maintain consistency across Brynhild deployments. Additional metadata is not supported within frontmatter; use references and assets subdirectories instead.

Create optional references/, scripts/, and assets/ subdirectories within your skill folder. References hold external links and structured data; scripts contain reusable code or workflows; assets store supporting files. This structure supports progressive disclosure without cluttering SKILL.md.

Skill patterns are proven structural templates for organizing knowledge, workflows, and tool integrations in Brynhild skills. Apply them when designing a new skill to ensure consistency, clarity, and compatibility across agent deployments.

The 500-line limit enforces progressive disclosure, preventing overwhelming documentation and keeping core skill logic readable. Extended content moves into references and assets, making skills maintainable and scanned quickly by agents.
