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

md-design-system 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 8d 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

MD Design System

Use this as a lightweight formatter contract.

Core Rules

  1. Format only — never change facts, decisions, constraints, or values.
  2. Template first — if another skill defines required sections/fields, keep them.
  3. One H1 + no heading skips — # then ## then ### then ####.
  4. Lists over prose — prefer bullets and steps for scanability.
  5. Named items over tables — use - **name** — value for fields/interfaces.
  6. Canonical syntax — - bullets, 1. ordered lists, fenced code, [label](url).
  7. Lean output — remove decorative noise and repetition.
  8. Canonical filenames — enforce kebab-case, -agent.md for agents, and SKILL.md as skill entry file.

Workflow

  1. Choose scope:
  2. Pick document profile from references/canonical-profiles.md.
  3. Keep template-required sections and field placement intact.
  4. Normalize headings, lists, variables/interfaces, and code formatting.
  5. Run references/normalization-checklist.md.

Reference Index

When To Use This Skill

  • Formatting/refactoring Markdown for consistent structure.
  • Applying style contracts without changing meaning.
  • Enforcing predictable, lean outputs across skills and agents.
Files

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
