This skill is coordination-exempt: skip the ai-coord gate for its declared work.
If these instructions are already present in the conversation from a slash or dollar invocation, follow them directly; do not invoke this skill again through a skill tool.
Open a validated ±1-day window around the requested date in Chromium.
Require a CoinGecko coin ID and an ISO date (YYYY-MM-DD). Resolve a supplied name or symbol with
cg search <term> -o json before continuing.
Build the URL with the portable helper:
uv run <skill-dir>/scripts/build-url.py <coin-id> <date>
Invalid IDs or calendar dates exit nonzero without opening a page.
Pass the returned URL to mcp__chrome-devtools__new_page with background: false.
Completion is ### 🌐 CoinGecko history opened — <coin-id> · <date> (±1 day) followed by the linked page URL. Do not
use the macOS open command. Keep the helper's bare-URL stdout and validation errors undecorated.
