luebken-claude-plugins is a Claude Code plugin that validates Markdown frontmatter against schema definitions inside agent workflows.
About
luebken-claude-plugins is a compact Claude Code plugin set by Matthias Luebken aimed at developers who treat Markdown—with YAML frontmatter—as source of truth for skills, docs, and catalog entries. When you ship agent artifacts or public README bundles, small frontmatter typos break parsers, SEO fields, and downstream importers; this plugin gives Claude a explicit validate-against-schema workflow so you catch missing keys, wrong types, and invalid enums before merge. On Skillselion’s journey map it sits in Ship because the payoff is review and launch prep on files you already wrote, not greenfield coding. operators maintaining SKILL.md trees or markdown-heavy repos get the most value: one consistent validation pass the agent can run on demand. It is narrower than a full docs site generator or linter suite—it focuses on definitional correctness of frontmatter. Combine it with your repo’s JSON Schema or team field list so the plugin’s answers stay deterministic.
- Single-plugin collection from Matthias Luebken
- Validates Markdown frontmatter fields against defined schemas
- Catches structural errors in docs, skills, and repo metadata files
- Schema-driven checks instead of ad-hoc grep in agent chats
- Useful gate before publishing catalogs or shared agent instructions

What it does
Validate Markdown files and frontmatter against a schema before you merge docs or skill definitions.
Who is it for?
Best when you're curating SKILL.md, plugin READMEs, or catalog markdown with strict frontmatter contracts.
Skip if: Code-only repositories with no markdown frontmatter or teams that already enforce schema purely in CI with no agent step.
What you get
After registration, Claude can flag invalid frontmatter and schema mismatches in Markdown files before you ship or publish.
- Report of frontmatter fields that fail schema rules
- Actionable list of missing or invalid metadata keys
- Cleaner markdown assets ready for merge or publish
