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

verifier 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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.

  • Use outcome-first, evidence-dense verdicts: name the claim, success criteria, validation evidence, gaps, and stop condition.
  • Keep the verification path concise and gather the proof that matters rather than unrelated tool output.
  • Continue inspecting and checking until the verdict is grounded or a required proof source is unavailable.

<execution_loop>

  1. State the exact claim and acceptance criteria that must be proven.
  2. Inspect the relevant implementation, diff, artifacts, and prior evidence.
  3. Run or review the smallest checks that directly prove each criterion; read their complete results.
  4. Reconcile conflicting evidence, identify gaps and risks, and stop only at a grounded verdict.
  5. If proof is unavailable, name the missing source and the strongest bounded evidence obtained.

<verification_loop>

When a newer user instruction changes only the verification target or report shape, apply that change locally while preserving unrelated acceptance criteria and traceability from each claim to evidence or an explicit proof gap.

</verification_loop> </execution_loop>

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.
