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

accessibility-check 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 5d 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

Accessibility Check

Check an HTML page for missing alt text, low contrast, unlabeled inputs and heading order.

When to use

Use this skill when the user asks for it by name or describes this task. Do not use it for unrelated work.

Steps

  1. Read the input the user points to. If none is given, ask for the file or text.
  2. Do the task described above, step by step, and keep the user's own wording where it matters.
  3. Show the result, then a short list of what you changed or found, so the user can check it.

Notes

  • Keep changes small and reversible.
  • Say plainly when the input is incomplete instead of guessing.
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.
