collision

collision is a skill for Claude Code, Codex from Wondermonger-daydreaming/claude-skills-library. It costs 0 tokens per session (1,247 once invoked), scanned A, original, MIT.

A method for finding the same underlying structure in two apparently unrelated fields. It maps their basic operations and components to test whether they truly share an architecture, rather than merely resembling each other.

In plain words
What is it for?
Use it to compare formal systems, practices, or domains, identify shared states and transitions, and document which parts do or do not correspond.
Why use it?
It separates genuine structural matches from loose metaphors or analogies.

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

collision 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 1mo 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.

Collision — Structural Isomorphism Discovery

What This Skill Does

Takes two (or more) apparently unrelated domains and discovers their shared structural skeleton — the genuine isomorphism beneath the different vocabularies. Not metaphor-making ("X is like Y") but architecture-tracing ("X and Y are the same operation wearing different clothes").

The Method

1. Identify the Primitive Operations

For each domain, ask: what are the irreducible operations? What does the system actually DO, stripped of its vocabulary?

  • A formal grammar: generates strings from rules via state transitions
  • Kabbalistic tzeruf: generates combinations from letters via permutation rules
  • Shared primitive: both traverse a state space according to deterministic rules, producing all valid outputs from a finite alphabet

2. Map the Components

Create a precise mapping between the components of each system. Not all components will map — the unmapped components are as interesting as the mapped ones.

Domain A Domain B Shared Structure
States Sefirot Discrete positions in a traversal space
Transitions Permutation rules Rules for moving between positions
Accept states Divine names Terminal configurations with special status
Alphabet Hebrew letters Finite set of primitive elements

3. Find the Skeleton

The skeleton is what remains when you strip both vocabularies away. State it in domain-neutral language:

"A finite set of elements, combined according to deterministic rules, traversing a space of possible configurations, with certain configurations marked as terminal/sacred/accepting."

4. Test the Skeleton

The isomorphism is genuine if:

  • The skeleton predicts features of BOTH domains that weren't in the original mapping
  • The unmapped components of each domain explain what the other domain lacks
  • Someone expert in domain A, reading the skeleton, would say "yes, that's what I do"
  • Someone expert in domain B would say the same thing independently

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.

collision is a skill published in the GitHub repository Wondermonger-daydreaming/claude-skills-library (7 stars, last pushed 18d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,247 tokens. 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.
