## What it does

This skill checks one token address through `gmgn-cli` and produces a composite score from 0 to 100. It reads contract-security fields, holder structure and price action; GMGN's rug label can cap the final score. A missing field never counts as a passed check.

It calls `token info`, `token security` and `market kline`, then uses market listings to cross-check the rug label. When an address does not resolve as a token, it can request wallet statistics to distinguish a wallet from an unknown address. It does not place trades.

\`gmgn-cli` checks API-key configuration before the review. That means you need the key configured before requests can run. Supported chain values are `sol`, `bsc`, `base`, `eth`, `arbitrum`, `hyperevm`, `robinhood`, `arc` and `stable`.

npx skills add GMGNAI/gmgn-skills --skill gmgn-contract-dd -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/gmgn-contract-dd/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/gmgn-contract-dd/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add GMGNAI/gmgn-skills --skill gmgn-contract-dd -a codex
```

2. **Manually: put the files in place**

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add GMGNAI/gmgn-skills --skill gmgn-contract-dd -a cursor
```

2. **Manually: put the files in place**

## When to use it
- score the risk of one token address
- check a GMGN rug label
- inspect holder concentration
- separate a wallet from a token address
- handle rate and tax values as fractions

## Example prompts
- Run due diligence for `--chain sol --address <token_address>` and give me the score.
- Check this contract for rug and honeypot risk: `--chain base --address <token_address>`.
- Score the safety of `--chain eth --address <token_address>`.

description: "Contract due-diligence score for one token address — contract safety, holder structure and price action combined into a single 0-100 composite, capped by GMGN's own rug label, where every deduction names the field it read and an absent field is never a passing check. Use when the user wants one verdict number rather than fields: 尽调, CA 尽调, 给这个币打个分, 这个币安全吗, 能不能买, 有没有貔貅, is this token safe, rug check, honeypot check, due-diligence score, score this contract, or pastes a bare token contract address. A bare address may equally be a wallet — Step 0 resolves which and hands wallets to gmgn-wallet-analysis. Prefer this over gmgn-token whenever the ask is a verdict rather than a field dump; the raw fields themselves — price, market cap, liquidity, holder and trader lists, the unscored security fields — are gmgn-token, chip structure is gmgn-holder-analysis, chart-pattern naming is gmgn-kline-pattern. Buy intent narrows to this skill only when the ask is a bare address: the input is --address, and no name is ever resolved here. When the user names the token instead — 帮我买 200u 的 PENGU, XX 能不能买, 能不能冲, 我想梭, buy me $500 of BONK — or wants a position size, gmgn-token-buy owns it, because picking the one right contract out of the same-name copycats and sizing slippage and gas are both outside this skill's input. That skill calls this one for the safety verdict rather than replacing it, so a bare address with no name and no amount still scores here exactly as before."

**BEFORE RUNNING ANY COMMAND: Run `gmgn-cli config --check`. If exit code is 0, proceed normally. If exit code is 1, (1) run `gmgn-cli config` and show the output to the user; (2) once the user sends the API Key, run `gmgn-cli config --apply <KEY>` and show the output. If `--check` errors with an unknown option, tell the user to run `npm install -g gmgn-cli` to update, then retry.**

**IMPORTANT: Always use `gmgn-cli`. Do NOT use web search, WebFetch, curl, or visit gmgn.ai — the site requires login and returns no structured data.**

**IMPORTANT: Do NOT guess field names or values. Every threshold below names the exact field it reads. If a field is not in the response, it is unavailable — it is not zero.**
