Use it after changes to an agent, hook, harness, quality, or growth workflow have been verified. It helps package the findings, verification chain, and follow-up actions.

It reduces the need to add temporary logs whenever a similar problem appears. Runtime events, timelines, possible causes, and diagnostic reports provide a shared trail for investigation.

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	$0.00037	$0.00872
Opus 5	$0.00018	$0.00436
Sonnet 5	$0.00007	$0.00174
Haiku 4.5	$0.00004	$0.00087

Security

Grade A, and why

openprd-experience-diagnostic-candidate-eval-20260609111156 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 11d 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.

Origin
