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 | $0.00065 | $0.10152 |
| Opus 5.5 | $0.00026 | $0.04061 |
| Sonnet 5.5 | $0.00013 | $0.02030 |
| Haiku 4.5 | $0.00006 | $0.01015 |
Grade A, and why
uniswap-v3-expert 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 17d 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.

Uniswap V3 Expert
Architecture Overview
Uniswap V3 is a concentrated liquidity AMM where each (tokenA, tokenB, fee) triple gets its own UniswapV3Pool contract, deployed via CREATE2 from a singleton UniswapV3Factory. LPs provide liquidity in discrete price ranges instead of across the full (0, infinity) curve, dramatically improving capital efficiency.
Contract Hierarchy
UniswapV3Factory (singleton)
├── creates UniswapV3Pool contracts via CREATE2 (one per token pair + fee tier)
│ ├── Core swap, mint, burn, collect, flash, observe logic
│ └── Stores tick state, positions, observations, and protocol fees
│
Periphery contracts (stateless routers / managers):
├── NonfungiblePositionManager — wraps LP positions as ERC-721 NFTs
├── SwapRouter (legacy v1) — single and multi-hop exact-input / exact-output swaps; Ethereum, Arbitrum, Optimism, Polygon only
├── SwapRouter02 — v2+v3 unified router with multicall
├── UniversalRouter — command-based router supporting v2, v3, permits, NFTs
├── Quoter — offchain swap simulation (reverts internally to return amounts)
├── QuoterV2 — returns sqrtPriceX96After, initializedTicksCrossed, gasEstimate
└── TickLens — batch read initialized ticks for a pool
Token Ordering
Uniswap V3 enforces token0 < token1 (by address). The factory and pool reject misordered pairs. Always sort before calling factory or pool functions:
(address token0, address token1) = tokenA < tokenB
? (tokenA, tokenB)
: (tokenB, tokenA);
Pool Address Derivation (CREATE2)
Pool addresses are deterministic. You can compute them offchain without querying the factory:
address pool = address(uint160(uint256(keccak256(abi.encodePacked(
hex"ff",
factory,
keccak256(abi.encode(token0, token1, fee)),
POOL_INIT_CODE_HASH
)))));
The POOL_INIT_CODE_HASH for Uniswap V3 is:
0xe34f199b19b2b4f47f68442619d555527d244f78a3297ea89325f843f87b8b54

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.

uniswap-v3-expert is a skill published in the GitHub repository ccashwell/evm-cortex (131 stars, last pushed 17d ago), licensed MIT. It adds 65 tokens to every session and 10,152 once invoked, about $0.0003 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.
