fix-frontmatter

fix-frontmatter is a skill for Claude Code, Codex from DailybotHQ/deepworkplan-skill. It costs 34 tokens per session (372 once invoked), scanned A, original, MIT.

A maintenance skill that checks and repairs the required frontmatter—the metadata block at the top of a `SKILL.md` file. It uses the repository's validator and repeats the check until it passes.

In plain words
What is it for?
Use it after adding or editing skills, or when the repository reports a `SKILL.md` frontmatter validation failure.
Why use it?
It fixes formatting and metadata errors that would otherwise cause continuous-integration checks to fail.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

fix-frontmatter scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Fix Frontmatter

Goal

Bring every SKILL.md under skills/ back into conformance with the frontmatter contract that CI enforces, so scripts/validate-frontmatter.py passes.

When to use

After adding or editing any SKILL.md, or when CI's "SKILL.md frontmatter validation" job fails.

Steps

  1. Run python3 scripts/validate-frontmatter.py and read every reported issue.
  2. For each flagged file, fix the frontmatter:
    • name: → kebab-case, starts with deepworkplan (e.g. deepworkplan-create)
    • version: → quoted SemVer ("2.8.0")
    • replace homepage: with documentation_url:
    • ensure --- delimiters and the required keys exist
  3. Re-run the validator until it prints OK: all N SKILL.md file(s) validated.

Validation

python3 scripts/validate-frontmatter.py exits 0.

Notes

Never edit a version: number to make the check pass — fix only quoting or format. The auto-release.yml bot owns version numbers (AGENTS.md §4). The validator scans skills/ only; .agents/skills/* is not CI-gated but follows the same style.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
