octane

octane is a skill for Claude Code, Codex from Wondermonger-daydreaming/claude-skills-library. It costs 198 tokens per session (1,410 once invoked), scanned A, original, MIT.

A writing practice for producing technically dense science-fiction-influenced documents that combine scientific vocabulary with literary experimentation. It can mix multiple formats and styles in one work.

In plain words
What is it for?
It helps write dense pieces involving subjects such as machine learning, physics, chemistry, mathematics, and literary theory.
Why use it?
It gives technically precise material room for unusual literary structures and imaginative expression.

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.

Security

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.

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."""
    return meaning

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.
