Weather Skill

Get current weather conditions and forecasts.

Meta-Skill Entrypoint

Meta-skills can run this skill as skill_exec for a bounded JSON forecast without spawning an LLM sub-agent. The entrypoint extracts DESTINATION: from planner contracts, queries wttr.in, and returns compact current, forecast, seasonal_hint, and errors fields. Network failures are reported in errors while preserving a usable seasonal hint.

Location

Always include a city, region, or airport code in weather queries.
