What it does
Gas is an agent skill from austintgriffith/ethskills. Current Ethereum gas prices, transaction costs, and the real economics of building on Ethereum today. Use when estimating costs, choosing between mainnet and L2s, or when a user asks about Ethereum being expensive. Counters the
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with Ethereum. The repository describes itself as: The missing knowledge between AI agents and production Ethereum.
When your agent uses it
- Estimating costs
- Choosing between mainnet and L2s
- A user asks about Ethereum being expensive
Example prompts
- “/gas”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- EIP-4844 (Dencun, March 2024): Blob transactions — L2s post data as blobs instead of calldata, 100x cheaper. L2 batch cost went from…
- Activity migration to L2s: Mainnet congestion dropped as everyday transactions moved to L2s.
- Pectra (May 2025): Doubled blob capacity (3→6 target blobs).
- Fusaka (Dec 2025): PeerDAS (nodes sample 1/8 of data) + 2x gas limit (30M→60M).
What it can do on your machine
Read from SKILL.md and the folder at commit 06ea4ef. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are javascript and bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
eth.llamarpc.com
Also links to:
data.chain.linketherscan.ioultrasound.moneyethskills.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Gas loads about 1.3k tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 567 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); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 567 words (~1,340 tokens).
“Your gas estimate is 100-600x too high. Most LLMs confidently state gas is 10-30 gwei. Post-Fusaka (Dec 2025), typical base fee is under 1 gwei — usually 0.1-0.5 gwei. Verify: cast base-fee --rpc-url https://eth.llamarpc.com”
