Use it after development checks, tests, or quality verification for agent, hook, harness, or quality changes. It helps document symptoms, relevant source files, reusable tests, and the next diagnostic checks.

When troubleshooting information exists only in temporary logs or chat, similar failures may require the same investigation again. This captures the evidence and verification chain for future work.

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	$0.00907
Opus 5	$0.00018	$0.00453
Sonnet 5	$0.00007	$0.00181
Haiku 4.5	$0.00004	$0.00091

Security

Grade A, and why

openprd-experience-diagnostic-candidate-eval-20260617115106 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 12d 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

This is a copy
