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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00021 | $0.01804 |
| Opus 5.5 | $0.00008 | $0.00722 |
| Sonnet 5.5 | $0.00004 | $0.00361 |
| Haiku 4.5 | $0.00002 | $0.00180 |
Grade A, and why
unworld 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.

Unworld Skill: Replace Time with Derivation
Status: ✅ Production Ready Trit: 0 (ERGODIC - derivational, not temporal) Principle: seed_{n+1} = f(seed_n, color_n) Frame: No external clock, only internal derivation
Overview
Unworld replaces temporal succession with derivational succession. There is no "time" - only seed-chaining where each state derives deterministically from the previous.
seed₀ → color₀ → seed₁ → color₁ → seed₂ → ...
The "next" is not temporal but derivational.
Core Formula
# Seed chaining: derive next seed from current seed + color trit
seed_{n+1} = (seed_n ⊕ (trit_n × γ)) × MIX mod 2⁶⁴
where:
γ = 0x9E3779B97F4A7C15 (golden ratio)
MIX = 0xBF58476D1CE4E5B9 (SplitMix64 multiplier)
⊕ = XOR
Why Replace Time?
- Determinism: Given genesis seed, entire chain is determined
- Parallelism: Any position computable without computing predecessors
- Verification: Chain integrity verifiable by re-derivation
- Frame invariance: No external clock → no observer-dependent ordering
Derivation Chains
1. Color Chain
Single stream of derivations:
Genesis: 0x42D
→ trit=+1 → #D8267F → seed₁
→ trit=0 → #2CD826 → seed₂
→ trit=0 → #4FD826 → seed₃
→ ...
Invariant: GF(3) balanced (sum of trits ≡ 0 mod 3)
2. Triadic Chain
Three interleaved streams from one genesis:
Genesis: 0x42D
MINUS: seed₀ → colors...
ERGODIC: seed₀ ⊕ γ → colors...
PLUS: seed₀ ⊕ (γ << 1) → colors...
Invariant: GF(3) conserved at each position across all three streams
3. 3-MATCH Chain
Sequence of 3-MATCH gadgets, each deriving from previous:
Match₀: [color_a, color_b, color_c] → combined_trit → seed₁
Match₁: [color_a', color_b', color_c'] → combined_trit' → seed₂
...
Invariant: Each match has GF(3) = 0
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.

unworld is a skill published in the GitHub repository plurigrid/asi (70 stars, last pushed 3mo ago), licensed MIT. It adds 21 tokens to every session and 1,804 once invoked, about $0.0001 per session on Opus 5.5. 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.
