# gmgn-callout-score Evaluates crypto callers on GMGN by token performance and dumping behavior. Helps you decide whether to follow a caller handle or wallet before risking funds. - skill · `type=skill` · Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode · 960 installs · ★ 626 - Author: GMGNAI - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/GMGNAI/gmgn-skills/tree/HEAD/skills/gmgn-callout-score/SKILL.md - Updated: 2026-10-23 - HTML: https://affpapa.org/en/nevibecode/skills/gmgn-callout-score ## What it does The skill evaluates cryptocurrency callers on GMGN across two dimensions: coin selection and post-call conduct. It checks whether recommended tokens actually gain traction and examines the author's real trading ledger. By comparing the first buy, the call timestamp, and subsequent sales, it measures whether a caller dumped tokens on followers instead of relying on self-reported claims. Users can supply either a wallet address or a Twitter handle. Execution depends on the `gmgn-cli` tool and a configured API key via `gmgn-cli config --apply `. The skill queries the CLI directly rather than scraping web pages. Network configuration requires strict attention: the CLI does not support IPv6. Running over IPv6 triggers authorization errors, so disabling IPv6 on the network interface is mandatory before querying. Analysis is strictly bounded to the last 30 days of activity. The skill does not perform token safety audits, nor does it assess whether the caller works well for copy trading. When token security is in doubt, running a separate contract audit is necessary. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add GMGNAI/gmgn-skills --skill gmgn-callout-score -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/gmgn-callout-score/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/gmgn-callout-score/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add GMGNAI/gmgn-skills --skill gmgn-callout-score -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/gmgn-callout-score/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add GMGNAI/gmgn-skills --skill gmgn-callout-score -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/gmgn-callout-score/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install GMGNAI/gmgn-skills gmgn-callout-score ``` 2. **Manually: put the files in place** - File: `.github/skills/gmgn-callout-score/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add GMGNAI/gmgn-skills --skill gmgn-callout-score -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/GMGNAI/gmgn-skills --path skills/gmgn-callout-score ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/gmgn-callout-score/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add GMGNAI/gmgn-skills --skill gmgn-callout-score -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/GMGNAI/gmgn-skills/tree/HEAD/skills/gmgn-callout-score/SKILL.md ## When to use it - evaluate caller credibility before buying recommended tokens - detect whether a caller dumps assets immediately after posting calls - verify call timestamps against the author's on-chain trade history - separate profitable token recommendations from artificial attention pumps ## Example prompts - Check this caller's score using --wallet on sol - Use gmgn-callout-score to see if --handle dumps on followers - Is it worth following calls from caller --handle ## Source text · SKILL.md · MIT Below is the content of a third-party file.

BEGIN THIRD-PARTY FILE 2a0726225cc91943 ```text --- name: gmgn-callout-score description: >- Decide whether to act on a caller's (喊单人) calls. Scores one call-out wallet on two axes — SELECTION (do the coins he calls actually run) and POST-CALL CONDUCT (does he sell into the attention his own call created) — then returns a follow / don't-follow verdict. The conduct axis is proved from the caller's own per-trade ledger, not from any self-reported field: for each sampled coin it compares the first buy, the call timestamp, and every sell after it, so "he dumped on his followers" is a measured sequence rather than an inference. USE THIS SKILL WHEN the user asks whether a caller is worth following: 这个喊单的能不能跟, 这个喊单号靠不靠谱, 喊单信誉分, 喊单评分, 他喊完会不会砸盘, 他是不是喊完就卖, 跟他的单能不能吃到, caller 评分, is this caller trustworthy, can I follow this caller's calls, does he dump after calling, call-out credibility score, score this caller. Accepts either a GMGN profile handle (twitter_username, e.g. the last path segment of a gmgn.ai/profile/ link) or a wallet address; a handle is resolved to one (chain, wallet) pair in Step 0 and the resolution is always echoed. The same questions in any other language route here — match on meaning, not wording. DO NOT USE THIS SKILL for raw call-out data — "这个钱包 喊过什么单", "最新喊单", "谁在喊这个币", "KOL 在喊什么", the feed, the field dump, the 30d summary card — that is gmgn-callout, which owns every read of the callout endpoints and returns them untouched; this skill calls it and adds a verdict. Nor for a caller judged as a trader rather than as a caller ("这个钱包能不能跟单", "跟单评分", copy-trade backtest) — that is gmgn-wallet-analysis / gmgn-wallet-score, which read his trades and know nothing about his calls. Nor for a token the caller mentioned ("他喊的那个币安全吗", 尽调, rug check) — that is gmgn-contract-dd. Nor for a token creator's next launch ("这个 dev 的新盘能不能买") — that is gmgn-dev-score. A bare wallet address with no call-out intent stays with gmgn-wallet-analysis; a bare token address stays with gmgn-contract-dd. This skill needs the word 喊单 / caller / call-out in the ask to own it. TIE-BREAKS, because three words are shared with neighbouring skills: 喊单 paired with 能不能跟 / 信誉 / 砸盘 / 评分 routes HERE, while ``` END THIRD-PARTY FILE 2a0726225cc91943 The third-party file has ended.
