What it does
Frontmatter Repair is an agent skill from LearnPrompt/LearnPrompt. Repair synthetic MDX frontmatter when title, description, or sidebar.order drift from the frontmatter contract. Use for files that follow the same observable patterns proven in the receipts; do not use on private transcripts, secret-bearing material, or arbitrary YAML.
Its SKILL.md is about 210 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts and reference files (for example `references/frontmatter-contract.md`).
It sits in Documents & Office, covering Markdown. The repository describes itself as: 永久免费开源的 AIGC 课程, 目前已支持Claude Code，Codex，Hermes，OpenClaw，Obsidian，Prompt Engineering, ChatGPT, Midjourney, Runway, Stable Diffusion, AI数字人，AI声音&音乐，开源大模型.
When your agent uses it
- Files that follow the same observable patterns proven in the receipts
- Do not use on private transcripts
- Secret-bearing material
Example prompts
- “/frontmatter-repair”
Requirements
- Node.js
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Read the frontmatter contract.
- Run node scripts/repair-frontmatter.mjs --file .
- Only repair rules proven by the receipts
- Preserve the body verbatim.
- Leave already-valid files unchanged.
- If the file contains private transcript material or secret markers, stop and escalate instead of repairing.
What it can do on your machine
Read from SKILL.md and the folder at commit 538921d. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (JavaScript), which the agent can run.
Shell commands in SKILL.md call:
node
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Frontmatter Repair loads about 212 tokens when it runs, and up to ~405 if it reads all its reference files. Until then it costs about 72 tokens; SKILL.md has 70 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 70 words (~212 tokens).
“Repair one synthetic MDX file at a time.”
