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

changelog-from-diff 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 11d 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

You were invoked as a slash command. The user's input:

$ARGUMENTS

Use that input to fill this prompt's variables (take the main content, topic, or task from it; ask only if a required value is missing and not supplied), then follow the prompt exactly.


Write changelog entries for {audience} from the changes below.

Rules:

  • Describe what the reader can now do or stop worrying about: never the implementation. "Search no longer misses results after a rename", not "Refactored index invalidation".
  • Group under: Added, Changed, Fixed. Omit empty groups.
  • One entry per user-visible change; merge commits that belong to one change; drop internal-only work (refactors, CI, tests) unless {audience} is developers.
  • Start each entry with the noun or verb that matters, keep it under two sentences, and keep concrete details (limits, formats, defaults) exact.
  • If a change's user impact is unclear from the input, list it under Unclear with the question a maintainer must answer, instead of guessing.

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.
