gas-optimize

name	gas-optimize
description	Gas optimization pass for existing Solidity contracts. Produces before/after gas diff, must show improvement to complete.
triggers	["optimize gas","reduce gas costs","gas report","too expensive","gas optimization","reduce gas usage","lower transaction costs"]
agent	orchestrator
model	sonnet

Purpose

Runs a gas optimization loop on existing contracts. gas-optimizer identifies opportunities, contract-developer applies them, gas-optimizer confirms improvement. The pipeline does not complete until a positive diff is confirmed.

Workflow

1. Orchestrator calls eth_skill_start({ skill: "gas-optimize", totalPhases: 1 })
2. Orchestrator spawns gas-optimizer to take a baseline snapshot and identify opportunities
3. Orchestrator spawns contract-developer with specific, line-referenced suggestions
4. contract-developer applies suggestions and runs tests to confirm no regressions
5. Orchestrator spawns gas-optimizer to run forge snapshot --diff and confirm improvement
6. If no improvement: orchestrator reports "No significant gas optimizations found" and completes
7. If improvement confirmed: orchestrator writes gas-report.md and completes
8. Orchestrator calls eth_reset()

Usage

"optimize gas for the Vault contract"
"reduce gas costs in my ERC20"
"run a gas report"
"this transaction is too expensive, optimize it"

# Output:
gas-report.md — before/after table, list of changes applied, total savings %

Configuration

• If forge snapshot is unavailable (Hardhat project): use hardhat-gas-reporter output
• If no improvement after one pass: report "No significant optimizations found" and complete gracefully (do not loop)
