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

aat-lint 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 12d 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

Run the anti-ai-tell linters on $ARGUMENTS (a file or directory; default: the current directory's changed files).

  1. For prose (.md, .txt): python3 ${CLAUDE_PLUGIN_ROOT}/skills/anti-ai-tell/lint.py <file> --prose
  2. For code/markup (.css, .tsx, .svg, .docx, ...): python3 ${CLAUDE_PLUGIN_ROOT}/skills/anti-ai-tell/visual_lint.py <file_or_dir>
  3. If a fingerprint.json exists, pass --fingerprint fingerprint.json so the user's chosen accent/font is not flagged.

Report the findings grouped by severity (Hard-tell / Strong-flag / Density-watch), then remind: a clean lint is the floor, not the ceiling — do the Tier-2 hand-pass (hierarchy, point of view, a rough edge) the linter can't see.

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.
