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

hermes-codex-operator AGENTS.md 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 2mo 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

Repository instructions

  • Keep the portable core independent of Telegram, Kanban, Codex Desktop UI, and private agent profiles.
  • Never add real prompts, results, receipts, identifiers, screenshots, user paths, hostnames, credentials, or runtime databases.
  • Use synthetic fixtures and temporary directories in tests.
  • Preserve the invariant: an ambiguous dispatch is UNKNOWN, never an automatic retry.
  • Treat App Server readback as authoritative; streamed text is not final proof.
  • Verification commands are argv arrays and must never use a shell.
  • Keep safe permissions as defaults. Broader access must be explicit caller configuration, never repository policy.
  • Run the unit suite and privacy gate before claiming completion.
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.
