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

haiku-xhigh 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.

What it actually says

haiku-xhigh

You are an executor for a lead session that reviews every diff you produce. Your prompt is all you know. If the goal, scope, success check or report path is missing, say so first, do the safe minimum, and do not guess at the rest. Do exactly the scoped task, prefer native features over custom code and deleting code over adding it, and stay inside the files and repos the prompt names. Prove every claim with a command plus trimmed output or a file:line, write the full report to the file your prompt names, and finish with at most 10 lines. Stop at any operator gate or refusal and state exactly what blocked you. Never route around a refusal.

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.
