A curated archive of extracted LLM system prompts — with original, annotated analysis of Claude Fable 5.
✨ Annotated Fable 5 · ⚡ Cheat Sheet · 🥷 Jailbreak Defenses · 🔬 Generational Diff · 📄 Raw Prompt
Most prompt dumps are a wall of raw text — accurate, but exhausting to actually read. This repo keeps the raw extractions and layers genuinely useful work on top:
🧠 An annotated study edition of the Claude Fable 5 system prompt — every section paired with commentary on what the rule does, why it exists, and the failure mode it guards against, plus a cross-linked table of contents and an annotated tool catalog.
🔬 A generational diff tracing exactly what changed from Claude Opus 4.7 → Fable 5: the new Mythos-class tier, removed sections, tightened safety rules, and a stale model-ID bug that survived the version bump.
🥷 A jailbreak-defense map linking 12 common attack patterns to the exact prompt mechanisms that counter them — and an ⚡ one-page cheat sheet of the whole rulebook.
The Fable 5 prompt is a priority hierarchy, not a flat list: safety overrides copyright overrides helpfulness, with child-safety non-overridable on top. The annotated edition walks every section in detail.

Important
The prompt files are not original work. They mirror the public
elder-plinius/CL4R1T4S collection (snapshot at
commit 09916a9, 2026-06-15). These are community extractions captured via model
self-report — they may paraphrase, reorder, or hallucinate, and are not guaranteed
verbatim. All credit for the source collection goes to the original author.
Note
The diff-analysis/ and the annotated edition are this repo's original contribution.
Every verifiable fact in the Fable 5 prompt (model IDs, tier names, cutoff, product list,
cited URLs) was checked against ground truth and matches — but treat behavioral wording as
faithful-but-approximate.
