What it does
Concepts is an agent skill from austintgriffith/ethskills. The essential mental models for building onchain — focused on what LLMs get wrong and what humans need explained. "Nothing is automatic" and "incentives are everything" are the core messages. Use when your human is new to onchain development, when they're designing a system, or when they ask "how does this actually work?" Also use when YOU are designing a system — the state machine + incentive framework catches design mistakes before they become dead code.
Its SKILL.md is about 3.1k 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. It works with Ethereum. The repository describes itself as: The missing knowledge between AI agents and production Ethereum.
When your agent uses it
- Your human is new to onchain development
- Theyre designing a system
Example prompts
- “Nothing is automatic”
- “incentives are everything”
- “re designing a system, or when they ask”
- “/concepts”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Who pokes it? (someone must pay gas)
- Why would they? (what's their incentive?)
- Is the incentive sufficient? (covers gas + profit?)
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 solidity).
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):
speedrunethereum.comethtechtree.comethereum.orgethskills.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
Concepts loads about 3.1k tokens when it runs. Until then it costs about 117 tokens; SKILL.md has 1,365 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 1,365 words (~3,068 tokens).
“"Smart contracts run automatically." No. Smart contracts cannot execute themselves. There is no cron job, no scheduler, no background process. Every function needs a caller who pays gas. This single misconception is the root cause of most broken onchain designs.”

What does Concepts do?
The essential mental models for building onchain — focused on what LLMs get wrong and what humans need explained. Concepts is an agent skill from austintgriffith/ethskills. The essential mental models for building onchain — focused on what LLMs get wrong and what humans need explained.
When should I use Concepts?
Concepts fits situations like: your human is new to onchain development; theyre designing a system.
How do I install Concepts in Claude Code?
Run `npx skills add austintgriffith/ethskills --skill concepts -a claude-code`. Or copy the skill folder (concepts in austintgriffith/ethskills) into .claude/skills/concepts in your project. Claude Code loads it when a task matches its description.
How do I install Concepts in Codex?
Run `npx skills add austintgriffith/ethskills --skill concepts -a codex`. Or copy the skill folder (concepts in austintgriffith/ethskills) into .agents/skills/concepts in your project. Codex loads it when a task matches its description.
Can I use Concepts in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add austintgriffith/ethskills --skill concepts -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/concepts, .gemini/skills/concepts, .github/skills/concepts and .opencode/skills/concepts in your project.
What does Concepts need to run?
SKILL.md names no scripts, command-line tools or credentials: Concepts is instructions for the agent only.
Does Concepts access the network?
SKILL.md names 4 domains. As links in the text: speedrunethereum.com, ethtechtree.com, ethereum.org and ethskills.com. This is read from the text; nothing was executed.
Is Concepts safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Concepts use?
No licence was found for Concepts or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Concepts use?
About 3.1k tokens (SKILL.md is roughly 12k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
