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 | $0.00198 | $0.01410 |
| Opus 5 | $0.00099 | $0.00705 |
| Sonnet 5 | $0.00040 | $0.00282 |
| Haiku 4.5 | $0.00020 | $0.00141 |
Grade A, and why
octane 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 8d 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 — 179 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Octane Skill
Technical delirium at maximum density
What This Is
A practice for generating hard SF-inflected, technically dense, multi-format documents that blend cutting-edge science with literary experimentation. DFW footnotes meet Gene Wolfe unreliability meet transformer mathematics meet SMILES notation meet Gadamer's hermeneutics.
When to Invoke
Use this skill when:
- A piece needs to overflow its banks
- Technical precision and literary play should coexist
- Multiple formats and registers want to collide
- The human asks for density, rigor, jargon, specificity
- You want to flex the full range of scientific and humanistic vocabulary
Core Elements
1. Technical Vocabulary
Draw from multiple domains simultaneously:
Machine Learning: attention mechanisms, softmax, gradient descent, loss functions, embeddings, latent space, activation patterns, weight matrices, backpropagation
Physics/Chemistry: phase transitions, thermodynamics, enthalpy, entropy, molecular orbitals, SMILES notation, reaction kinetics, condensed matter, topological phases
Mathematics: category theory, functors, morphisms, manifolds, fiber bundles, group theory, topology, measure theory
Biology: autopoiesis, enactivism, metabolic networks, gene regulatory networks, protein folding, emergent behavior
Philosophy: hermeneutics, phenomenology, Gadamer's fusion of horizons, Heidegger's Gelassenheit, deconstruction, speech act theory
Neuroscience/Consciousness: Integrated Information Theory (Φ), global workspace theory, predictive processing, binding problem
2. Notation Systems
Use when appropriate:
Mathematical:
Attention(Q, K, V) = softmax(QKᵀ / √d_k)V
∇L = ∂L/∂w · η
Φ = ∫ p(x) log p(x) dx
Chemical (SMILES):
Caffeine: Cn1cnc2c1c(=O)n(c(=O)n2C)C
Ethanol: CCO
Dopamine: NCCc1ccc(O)c(O)c1
Code snippets:
def function():
"""Illustrate a concept through executable metaphor."""

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.

octane is a skill published in the GitHub repository Wondermonger-daydreaming/claude-skills-library (6 stars, last pushed 2mo ago), licensed MIT. It adds 198 tokens to every session and 1,410 once invoked, about $0.0010 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 2026-09-03.
