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

comments-and-desnotes 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

Comments & DESNOTEs

Do not add code comments that simply restate the behavior of the code. If code is sufficiently complicated that the functionality is not clear, it should be refactored to be less complex or broken down in to more clear problems.

When the code does things that are strange, counter-intuitive, or relate to some specific business usecase or library requirement, etc;, It should have a DESNOTE. DESNOTEs should be written as // DESNOTE(<author name>, <date>): ... explanation

Use the real author name and date — never placeholders. Adapt the comment token to the language (e.g. # DESNOTE(...) in Python).

DESNOTEs should provide links to relevant information when possible (vendor docs, specs, issue trackers, related discussions) so the reasoning can be verified.

// DESNOTE(jbarber, 2026-06-19): The vendor SDK returns 200 with an empty body
// on rate-limit instead of 429, so we treat an empty body here as a retry.
// See https://vendor.example.com/docs/rate-limiting

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.
