What it does
Optimizing Gas Fees is an agent skill from jeremylongshore/tons-of-skills-marketplace. Optimize blockchain gas costs by analyzing prices, patterns, and timing. Use when checking gas prices, estimating costs, or finding optimal windows. Trigger with phrases like "gas prices", "optimize gas", "transaction cost", "when to transact".
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 14 other files, including scripts and reference files (for example `ARD.md`, `PRD.md` and `config/settings.yaml`). Compatibility notes: Designed for Claude Code
It works with Ethereum. 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. The licence is MIT.
When your agent uses it
- Checking gas prices
- Estimating costs
- Finding optimal windows
- With phrases like gas prices
Example prompts
- “gas prices”
- “optimize gas”
- “transaction cost”
- “/optimizing-gas-fees”
Requirements
- Python 3
- A credential in ETHERSCAN_API_KEY
- Compatibility (from SKILL.md): Designed for Claude Code
- Pre-approved tools (allowed-tools): Read, Bash(python3:*)
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Check current gas prices (optionally for a specific chain)
- Estimate transaction cost for known operations or custom gas limits (available operations: eth_transfer, erc20_transfer, erc20_approve…
- Find the optimal transaction window with lowest expected gas
- View gas patterns (hourly or daily)
- Predict future gas prices for a given hour
- Compare gas prices across multiple chains
- View base fee history for recent blocks
What it can do on your machine
Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadBash(python3:*)
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 5 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
eips.ethereum.orgetherscan.iol2fees.info
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
ETHERSCAN_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Compatibility
Designed for Claude Code
From compatibility in the SKILL.md frontmatter.
Context cost
Optimizing Gas Fees loads about 1k tokens when it runs, and up to ~4k if it reads all its reference files. Until then it costs about 66 tokens; SKILL.md has 294 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Optimizing Gas Fees
Overview
Gas fee optimization skill that:
- Fetches real-time gas prices from multiple sources
- Estimates transaction costs in ETH and USD
- Analyzes historical patterns to find optimal timing
- Predicts future gas prices
- Compares gas across multiple chains
Prerequisites
- Python 3.8+ with requests library
- Network access to RPC endpoints
- Optional:
ETHERSCAN_API_KEYfor higher rate limits - Optional: Custom RPC URLs via environment variables
Instructions
Check current gas prices (optionally for a specific chain):
bash cd ${CLAUDE_SKILL_DIR}/scripts && python3 gas_optimizer.py current cd ${CLAUDE_SKILL_DIR}/scripts && python3 gas_optimizer.py current --chain polygonEstimate transaction cost for known operations or custom gas limits (available operations:

Output
- Current: Base fee, priority fee, and tier prices (slow/standard/fast/instant)
- Estimate: Gas cost in native token and USD for each tier
- Patterns: Historical hourly/daily patterns with low-gas markers
- Optimal: Recommended transaction window with expected savings
- Predict: Gas forecast for specific time with confidence
- Compare: Side-by-side gas prices across chains
