BEFORE RUNNING ANY COMMAND: Run gmgn-cli config --check. Exit 0 → proceed. Exit 1 → run gmgn-cli config, show the output, and once the user sends the API key run gmgn-cli config --apply <KEY> and show that output. If --check is an unknown option, tell the user to run npm install -g gmgn-cli, then retry.

IMPORTANT: Always use the pre-installed gmgn-cli binary. Never use web search, WebFetch, curl, npx, or gmgn.ai — the site requires login and exposes no structured data.

⚠️ IPv6 IS NOT SUPPORTED. On a 401/403 with correct credentials, check ifconfig | grep inet6 (macOS) or ip addr show | grep inet6 (Linux) and fetch https://ipv6.icanhazip.com. If an IPv6 address comes back, tell the user to disable IPv6 — gmgn-cli works over IPv4 only.

Run

python3 ~/.claude/skills/gmgn-dev-score/dev_score.py <chain> <dev_address> [max_pages]

max_pages defaults to 25 and only bounds the trade walk; raise it for a dev with hundreds of launches — the JSON says when it truncated. The script prints one JSON object on stdout (progress and rate-limit notes go to stderr). It computes; it writes no report. You write the report, from that object, in the user's language.
