What is prepare-experiment?

A pre-launch checklist for a machine-learning training round or experiment. It checks the logging contract, including training and validation loss, and sets the order for a smoke test followed by the full training chain.

Use it before launching training jobs or adding an experiment arm on the named systems, and again whenever the trainer changes.

It catches logging and setup problems before a long training run starts. Repeating it after trainer changes helps keep results comparable and recorded consistently.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00132	$0.01290
Opus 5.5	$0.00053	$0.00516
Sonnet 5.5	$0.00026	$0.00258
Haiku 4.5	$0.00013	$0.00129

Security

Grade A, and why

prepare-experiment 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 8d 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 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.
