Historical Page Fallback

Open CoinGecko's historical-data page only when cli-coingecko routes a request here after a genuine CLI failure and a visual result can satisfy the request.

Workflow

1. Require a CoinGecko coin ID and an ISO date (YYYY-MM-DD). If cg search still works, use it to resolve a supplied name or ambiguous symbol. If the entire CLI is unavailable, resolve the ID through CoinGecko's website search in Chromium and confirm the page slug; never infer an ID from a symbol.

2. Build the validated ±1-day URL:

   uv run <skill-dir>/scripts/build-url.py <coin-id> <date>

   Invalid IDs or calendar dates exit nonzero without opening a page.

3. Pass the returned URL to Chrome DevTools new_page with background: false. Do not use the macOS open command.

4. Complete with ### 🌐 CoinGecko history opened — <coin-id> · <date> (±1 day), the linked page URL, and a concise disclosure of the CLI failure that triggered the fallback. Keep the helper's bare-URL stdout and validation errors undecorated.

Boundaries

• Do not use this route for authentication, tier, rate-limit, invalid-input, or ambiguity errors.
• A browser page is not machine-readable evidence. If the user requested JSON, CSV, or an exact export, report the CLI failure without claiming completion.
