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

a11y 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 7d 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

/holocron:a11y

Target: $ARGUMENTS — or the working-tree diff if no arg.

Gather

  • If no arg: git diff --name-only filtered to UI files (.tsx, .jsx, .vue, .svelte, .html, .astro).
  • If arg is a file: that file.
  • If arg is a directory: UI files under it (at most 20 — if more, ask the user to narrow).

Delegate

Spawn @a11y-auditor on the selected files. Feed it the files and ask for:

  • Blocker / Serious / Minor findings
  • WCAG success criterion (or clear reason) per finding
  • Concrete fix per finding, with file:line

Output

Group findings by severity. If a component is clean, say so — do not invent findings.

After

If the user wants durable rules from this pass (e.g. "we always set lang on <html>"), suggest /holocron:learn.

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.
