What it does
Crops is an agent skill from austintgriffith/ethskills. Use for every Ethereum dApp architecture plan and for reviews of existing systems, trust assumptions, custody, admin keys, pause or upgrade powers, hosted infra (RPC, indexer, paymaster, bundler, frontend host, oracle, sequencer), privacy, identity flows, agent permissions, stablecoin issuer risk, censorship resistance, user exit, and restrictive licenses (BUSL, SSPL). CROPS means Censorship Resistance, Open Source and Free, Privacy, Security.
Its SKILL.md is about 5.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Backend & APIs, covering Smart contracts and Crypto and DeFi analysis. It works with Ethereum. The repository describes itself as: The missing knowledge between AI agents and production Ethereum.
When your agent uses it
- Every Ethereum dApp architecture plan and for reviews of existing systems
- Trust assumptions
- Hosted infra (RPC
- Agent permissions
Example prompts
- “/crops”
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 markdown).
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):
l2beat.comblog.ethereum.orgethereum.foundation
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
Crops loads about 5.6k tokens when it runs. Until then it costs about 113 tokens; SKILL.md has 2,718 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 2,718 words (~5,566 tokens).
“CROPS is the Ethereum Foundation's shorthand for the properties Ethereum must preserve: Censorship Resistance, Open Source and Free (as in Freedom), Privacy, Security. This skill turns those values into concrete dApp and smart contract architecture checks.”
