zaryab2000/decipher-gas-optimizoor
Skill Claude CodeCodex
Analyzes foundry.toml optimizer configuration for Foundry-based Solidity projects. Detects suboptimal optimizerruns settings relative to contract call frequency, missing viair flag for complex contracts, and outdated Solidity versions missing built-in optimizer gains. Covers CO-001 (optimizerruns tuning), CO-002…
zaryab2000/decipher-gas-optimizoor
Skill Claude CodeCodex
Detects deployment cost inefficiencies in Solidity: factory patterns that deploy full contracts when ERC-1167 minimal proxies would suffice, non-payable admin functions with unnecessary ETH check overhead, dead code paths inflating bytecode, and opportunities for vanity addresses via CREATE2 for high-frequency…
zaryab2000/decipher-gas-optimizoor
Skill Claude CodeCodex
Detects storage slot inefficiencies in Solidity contracts: struct packing gaps, suboptimal field ordering, mapping-vs-array tradeoffs, SSTORE2 for large static data, transient storage for within-transaction state, and batch mutation patterns. Use when writing or reviewing struct definitions, state variable…
Skill Claude CodeCodex
Analyze and optimize gas consumption in Solidity smart contracts using proven patterns and best practices.
Skill Claude CodeCodex
Use when analyzing EVM/DeFi arbitrage opportunities — cross-DEX spot spreads, triangular cycles, stablecoin depegs, or MEV/price dislocation — or when the user wants opportunities quantified net of fees, gas, and slippage. Analysis only, not trade execution.
Skill Claude CodeCodex
Use when reducing gas costs, auditing gas usage, or refactoring Solidity/Yul for efficiency — when a contract should be cheaper to deploy or call, or when the user mentions high gas fees, SSTORE/SLOAD costs, storage packing, calldata vs memory, unchecked math, loop costs, or transient storage (EIP-1153).
Skill Claude CodeCodex
Use when auditing an EVM/Solidity contract for security vulnerabilities — including reentrancy, access-control gaps, EIP-7702 delegation risks, EIP-1153 transient storage flaws, unsafe delegatecall, or hardcoded secrets — or when evaluating contract safety and producing a severity-rated finding set.
