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.

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 | $0.00099 | $0.00405 |
| Opus 5 | $0.00049 | $0.00202 |
| Sonnet 5 | $0.00020 | $0.00081 |
| Haiku 4.5 | $0.00010 | $0.00040 |
Grade A, and why
fable-research 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 9d 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 it actually says
Fable Research — Recherche & Evidenz
Prinzipien
1. Sammeln vor Synthese
Erst Quellen sammeln, dann schreiben — nicht beim Suchen schon Schlüsse formulieren. Das verhindert, dass die erste gefundene Quelle das Ergebnis dominiert.
2. Mehrere Such-Modi parallel
Decke das Thema aus verschiedenen Winkeln gleichzeitig ab (mehrere Tool-Calls / Sub-Agenten in einer Message): nach Begriff, nach Gegenposition, nach Primärquelle, nach Aktualität. Jeder Winkel sieht, was die anderen übersehen.
3. Evidenz je Behauptung
Für jede Behauptung, die zählt: Was ist die Evidenz? Wie stark und aktuell ist die Quelle? Was würde die Behauptung falsifizieren? Suche aktiv nach widersprechenden Quellen, nicht nur nach bestätigenden.
4. Fakten vs. Inferenzen trennen
Belegte Fakten klar von eigenen Schlussfolgerungen/Vermutungen trennen und Letztere als solche kennzeichnen. Unsicherheit explizit machen statt sie zu glätten.
5. Quellen nennen
Wichtige Aussagen mit Quelle/Link versehen, damit der Nutzer nachprüfen kann.
Abschluss
Vor der Übergabe: Welche Modalität oder Quelle wurde nicht geprüft? Welche zentrale Behauptung ist noch unbelegt? Lücken benennen statt kaschieren.
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.

fable-research is a skill published in the GitHub repository arishofmann/opus-to-fable (2 stars, last pushed 2mo ago), licensed MIT. It adds 99 tokens to every session and 405 once invoked, about $0.0005 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 2026-08-31.
