What Gas Fee Optimizer is

Gas Fee Optimizer is a plugin published in the jeremylongshore/tons-of-skills-marketplace repository on GitHub, which has about 2.8k stars. The repository describes itself as: “Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com.”

A plugin is a package that bundles skills, slash commands, subagents, hooks, and MCP connectors so they install together. Plugins are plain files with a manifest at .claude-plugin/plugin.json, and they work in both Claude Code and Claude Cowork.

Installing Gas Fee Optimizer adds everything it ships in one step. Connectors inside a plugin still need to be connected separately, and hooks and subagents only run in Cowork and Claude Code, not in regular chat.

How to install Gas Fee Optimizer

Claude Code

Add the repository as a plugin marketplace: claude plugin marketplace add jeremylongshore/tons-of-skills-marketplace
Install the plugin: claude plugin install gas-fee-optimizer@<marketplace-name>, using the marketplace name from the repository's .claude-plugin/marketplace.json.
Restart the session if the new skills or commands don't appear straight away.

Claude Cowork

Open Customize → Plugins and choose Add marketplace.
Enter jeremylongshore/tons-of-skills-marketplace (the owner/repo shorthand works for GitHub).
Find Gas Fee Optimizer in the list, click Install, then connect any connectors it needs from its Connectors tab.

Optimize Ethereum transaction gas fees through strategic timing, routing alternatives, and Layer 2 solutions.

Installation

/plugin install gas-fee-optimizer@claude-code-plugins-plus

Usage

Optimize Gas Command

/optimize-gas

Or use the shortcut:

/gas

Example Queries

# Check current gas prices
/gas What's the current gas price on Ethereum?

# Timing optimization
/gas Should I mint this NFT now or wait for lower gas?

# Compare networks
/gas Compare gas costs: Ethereum mainnet vs Arbitrum vs Polygon

# Transaction-specific advice
/gas I need to swap 1 ETH for USDC - what's the best strategy?

# Historical analysis
/gas When is the best time of day to make transactions?

Features

Real-Time Gas Analysis - Current base fee and priority recommendations
Historical Context - Compare to 24h and 7-day averages
Timing Optimization - Best time windows for low-fee transactions
L2 Comparisons - Gas costs across Arbitrum, Optimism, Base, zkSync
Sidechain Options - Polygon, Gnosis Chain alternatives
Cost Estimates - Transaction-specific cost calculations
Strategic Recommendations - Wait vs execute now analysis

What It Analyzes

Current Network State - Base fee, congestion level
Historical Patterns - Typical low-fee periods
Transaction Type - Gas estimates for different operations
Alternative Routes - L2 and sidechain comparison
Urgency Factor - Time-sensitive vs routine transactions
Cost-Benefit - Savings from waiting vs opportunity cost

Output Includes

Current gas price breakdown (base + priority fee)
Estimated costs for common transaction types
Historical comparison (percentile ranking)
Best time windows for transactions
L2/sidechain cost comparison table
Specific optimization strategies
Wait vs execute recommendation

Transaction Types Covered

Simple Transfers - ETH sends (~21,000 gas)
Token Transfers - ERC-20 operations (~65,000 gas)
DEX Swaps - Uniswap, SushiSwap (~150,000 gas)
NFT Mints - Collection minting (~200,000 gas)
DeFi Operations - Lending, staking, yield farming (varies)

Layer 2 Networks Compared

Arbitrum - Optimistic rollup, high liquidity
Optimism - Optimistic rollup, EVM-equivalent
Base - Coinbase L2, fast finality
zkSync - Zero-knowledge rollup, high security
Polygon - Sidechain, lowest cost
Gnosis Chain - xDai sidechain

Optimization Strategies

Timing

Identify low-congestion time windows
Historical pattern analysis
Weekend vs weekday comparison

Routing

L2 migration for frequent users
Sidechain alternatives for specific use cases
Bridge cost calculations

Technical

Batch transaction recommendations
Gas-efficient contract interactions
Approval optimization

Important Notes

Gas prices are highly volatile and unpredictable
Historical patterns don't guarantee future prices
Consider transaction urgency and value
Bridge costs may negate L2 savings for one-time transactions
Opportunity cost of waiting may exceed gas savings
This is optimization guidance, not financial advice

Requirements

Transaction type or operation description
(Optional) Urgency level
(Optional) Transaction value for cost-benefit analysis

Before you install

Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
Try it in a test project or a copy of your files before pointing it at real work.
Pin the version you tested, and review changes before updating.
Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
