Open-Meteo Historical Weather

Use the CLI-owned open-meteo.historical-weather capability. This Skill supplies intent routing and result-use boundaries only; the CLI owns source discovery, input/output schemas, HTTP behavior, limits, validation, and receipts.

Before running

1. Read references/tiangong-data-requirement.json.
2. Use the caller- or workspace-resolved stable CLI. The requirement declares compatible capability and operation contract majors; it does not select a package build.
3. Run data describe with that same CLI. Continue only when the capability ID, required contract majors, and the open-meteo.series-all-null operation feature match; then copy the exact current capability/operation versions from that response into the run request.
4. Run the default static doctor. Do not add --live unless the user explicitly asks for a provider probe.
