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 | $0.00000 | $0.01247 |
| Opus 5.5 | $0.00000 | $0.00499 |
| Sonnet 5.5 | $0.00000 | $0.00249 |
| Haiku 4.5 | $0.00000 | $0.00125 |
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.
How it starts
The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.
