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> to complete configuration and verification, then show the output to the user. If --check returns an error (unknown option or command not found), tell the user to run npm install -g gmgn-cli to update, then retry.

IMPORTANT: Always use gmgn-cli commands. Do NOT use web search, WebFetch, curl, or visit gmgn.ai — the website requires login and does not expose structured data.

IMPORTANT: Do NOT guess field names or values. Fields not listed in Field Reference below have not been confirmed against the live API — if the script's defensive lookups come back empty for them, degrade gracefully (see Notes) rather than inventing a value.

⚠️ IPv6 NOT SUPPORTED: If you get a 401 or 403 error and credentials look correct, check for IPv6 immediately: (1) list all network interfaces and their IPv6 addresses — run ifconfig | grep inet6 (macOS) or ip addr show | grep inet6 (Linux); (2) send a test request to https://ipv6.icanhazip.com — if the response is an IPv6 address, outbound traffic is going via IPv6. Tell the user immediately: "Please disable IPv6 on your network interface — gmgn-cli commands only work over IPv4."

When the user gives a wallet address, extract --chain and --wallet from their message, then run the analysis script below — it computes all three angles (profitability, copy-tradeability, Dev reputation) from a single shared data pull, regardless of which one the user actually asked about. Also detect the user's language: set LANG to 'zh' if the user wrote in Chinese, 'en' if in English (default 'zh'). Ask for --latency / --slippage / --gas only if the user wants a customized backtest — otherwise use the defaults baked into the script. Once the script runs, decide which section to lead with in your reply — see Framing the Report by Question below.

Core Concepts

This skill deliberately splits "is this trader good?" from "can you copy it?" — a wallet can be great at trading and terrible to copy, or mediocre at trading but easy to ride along with:

Track-record score (0–100) — Is this trader actually good, judged by outcome distribution, not just win rate. A wallet with a 30% win rate can still score high here if it cuts losses hard and the 30% that win pay for the rest — that's disciplined risk management, not luck.
Copy-tradeability score (0–100) — Even if the wallet is genuinely skilled, can you capture that edge? A wallet that snipes sub-$100k market caps or round-trips in 5 seconds is not copyable — by the time your transaction lands, the wallet has already exited and you're the exit liquidity. This score penalizes early entries, thin per-trade margins, ultra-short holds, and bot-tier trade frequency.
Backtest estimate — A concrete "what you'd actually keep" number: the wallet's raw return minus your entry-latency price drift, minus round-trip slippage, minus gas — using the latency/slippage/gas the user specifies (or sane defaults).
Dev-reputation score — Only computed when the wallet is itself a token creator (its created_token_count exceeds half its traded-token count — i.e. it's mostly launching, not trading). Judges the wallet as a developer: survival rate of tokens it created, how many are stuck on the bonding curve and never graduated, and whether its recent launches passed a basic security check. When this applies, entry-timing / win-rate factors are unreliable (the wallet controls its own token's price and holder list) — the track-record and copy-tradeability scores are shown at a steep discount, and the verdict pivots to Dev reputation instead.
No trading history — If the wallet has zero buy/sell transactions in the sampled period (only transfers/airdrops), none of the above can be computed honestly. The script detects this and reports it plainly instead of forcing a score onto empty data.
