This file provides guidance to Claude Code when working with the gmgn-cli plugin.

CRITICAL RULE — Read This First

ALL queries about GMGN data MUST use gmgn-cli via the skills below.

This includes: trending tokens, token info, security checks, K-line / price history, wallet holdings, KOL trades, Smart Money trades, swaps, and any other on-chain data.

NEVER do any of the following to fetch GMGN data:

• Web search (e.g. searching "gmgn trending solana")
• WebFetch / curl to gmgn.ai or any gmgn domain
• Browser automation or scraping
• Any method other than gmgn-cli

Why: The gmgn.ai website requires login, uses dynamic rendering, and does not expose structured data. The CLI is the only correct and supported method. If you attempt to scrape the site, you will get no data or be blocked.

When a user asks anything about GMGN data — always invoke the matching skill and run the CLI command. No exceptions.

Project Overview

This is a Claude Code plugin — a collection of GMGN OpenAPI skills for on-chain operations. It provides CLI tools and skills for token queries, market data, wallet portfolio analysis, and swap execution across sol / bsc / base.

Available Skills

Skill	Purpose	When to Use
gmgn-token	Token info, security, pool, holders, traders	User asks about a token's price, market cap, security risk, liquidity pool, top holders, or top traders; user wants to research a token before buying; user asks "is this token safe", "who holds this token", "what's the liquidity"
gmgn-market	K-line / candlestick market data + trending tokens + newly launched launchpad tokens	User asks for price history, chart data, OHLCV candles, trading volume over time; user wants to analyze price trends; user asks "show me the 1h chart", "what was the price last week", "give me kline data for this token"; user wants to discover hot or trending tokens; user asks "what tokens are trending", "show me top tokens by volume", "find hot tokens on SOL"; user asks about newly launched tokens, fresh tokens, latest tokens on launchpads — e.g. "show me new tokens on pump.fun", "what tokens just launched on SOL", "find newly created tokens", "latest tokens on letsbonk" → use market trenches --type new_creation
gmgn-portfolio	Wallet holdings, activity, trading stats, token balance	User asks about a wallet's holdings, P&L, transaction history, trading statistics, or token balance; user wants to analyze a wallet; user asks "what tokens does this wallet hold", "show me recent trades", "what's the win rate of this wallet"
gmgn-track	Track trade activity of wallets I follow, KOL trades, Smart Money trades across chains	User asks about trades from wallets they follow; user wants to see what KOLs or Smart Money are buying/selling; user asks "show me what wallets I follow have traded recently", "what are KOLs buying", "show me smart money moves on BSC"
gmgn-swap	Token swap execution + order status query	User wants to swap tokens, execute a trade, or check an order status; user asks "swap SOL for USDC", "buy this token", "check my order"; requires private key configured in .env

Architecture

• src/ — TypeScript source (CLI commands, API client, signer)
• skills/ — 5 SKILL.md files for Claude Code skill definitions
• dist/ — Compiled output (generated by npm run build)
• .claude-plugin/ — Plugin metadata for Claude Code

Prerequisites

Config lookup order (project overrides global):

1. ~/.config/gmgn/.env — global config, set once for all projects
2. .env in the current working directory — project-level override (takes precedence)

Required variables:

• GMGN_API_KEY — apply at https://gmgn.ai/ai
• GMGN_PRIVATE_KEY — PEM content, required for swap/order commands only

If the user has not configured credentials or commands fail with a missing key error, guide them to create ~/.config/gmgn/.env:

mkdir -p ~/.config/gmgn
cat > ~/.config/gmgn/.env << 'EOF'
GMGN_API_KEY=your_api_key_here
EOF

Auth Modes

Mode	Commands	Requirements
Normal	token / market / portfolio	GMGN_API_KEY only, no signature
Critical	swap / order	GMGN_API_KEY + GMGN_PRIVATE_KEY — CLI handles signing automatically

SKILL.md Authoring Rules

When creating or updating any file in skills/:

• Language: English only — no bilingual content. SKILL.md files are read by AI, not humans.
• Package runner: Always use the pre-installed gmgn-cli binary (e.g. gmgn-cli token info ...). Never use npx gmgn-cli or npx gmgn-cli@<version> — npx downloads the package at runtime alongside live credentials. The package must be installed once with npm install -g gmgn-cli.
• Section order: Sub-commands → Supported Chains → Prerequisites → Parameters/Options (if needed) → Usage Examples → Notes
• --raw flag: All commands support --raw for single-line JSON output. Always document it in the Notes section.
• YAML frontmatter: Quote argument-hint values that contain | characters to avoid YAML parsing errors.

Keeping Docs in Sync

src/commands/*.ts is the single source of truth for all commands, sub-commands, and options.

When any file in src/commands/ is modified, you MUST also update:

1. skills/gmgn-{command}/SKILL.md — Sub-commands table and Options tables must exactly reflect the current command definitions.
2. Readme.md — The ## Commands section bash examples must reflect added/removed commands or options.
3. Readme.zh.md — Same as Readme.md for the bash examples (Chinese descriptions are maintained separately).
