Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00038 | $0.00659 |
| Opus 5 | $0.00019 | $0.00329 |
| Sonnet 5 | $0.00008 | $0.00132 |
| Haiku 4.5 | $0.00004 | $0.00066 |
Grade A, and why
publish-the-run-that-did-not-work 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.
How it starts
The opening of the file, as written. The whole thing — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Trigger
You ran a comparison to decide whether a change helps, and the result is inconvenient: negative, not significant, or contradicting something already announced.
It does not apply to a run that was simply broken — a crashed harness measured nothing, and publishing it as a result would be its own kind of noise. Fix and rerun, and say that you did.
Do
- Write down, before running, what outcome would kill the claim. If you cannot name it, the experiment cannot fail, and an experiment that cannot fail is not one.
- Report the effect with an interval, not a point estimate.
+9.8pp [−3.5, +16.7]says something+9.8ppdoes not. - When a later run supersedes an earlier one, keep the earlier one published and unedited, and link the correction. Amending it removes the only evidence that the correction happened.
- If a claim does not survive replication, retract it in the same place it was made, in the same size type.
Avoid
Rerunning until it looks better and reporting the best run. That is not a bad measurement, it is a selected one, and selection cannot be detected in the number afterwards by anyone — including you.
Avoid quietly dropping the negative result while keeping the positive one from the same series. Avoid pooling a fresh sample with an old one after seeing that pooling helps; if pooling was not pre-registered as primary, it is secondary and must be labelled that way.
And avoid describing a non-significant delta with words that imply significance: "improved", "lifted", "up from". "Not significant on its own" is the sentence.
Check
Ask what a sceptical reader could conclude from the artefacts you published. If the answer requires trusting that you did not discard anything, the artefacts are incomplete — publish the journal, the per-item outcomes, or the raw pairs.
Then check the claim in your own README against the results section. If one says a thing the other retracts, the retraction is the true one and the claim has to move.
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.

publish-the-run-that-did-not-work is a skill published in the GitHub repository brcampidelli/chimera-agent (25 stars, last pushed today), licensed Apache-2.0. It adds 38 tokens to every session and 659 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
