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

go 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 13d 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

/go — Browser check

Verify the work in a real browser instead of trusting that it compiles. Use whichever browser tooling is available and fits the check best.

Easy to miss:

  • Functional result — the page does what was intended, not just renders. A search for "X" shows results about X.
  • Console and network — JS errors and failed requests (4xx/5xx) break things silently.

A login wall is not a reason to stop. Use test credentials from the project's env files or secrets manager, or a browser where the user is already signed in; that also covers SSO, OAuth and MFA. On a deployed site that session is the user's real account, so check without changing data.

If something is broken, fix and verify again; when the same issue keeps failing, ask for direction.

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.
