weather-poet

Overview

A weather poet agent that retrieves live conditions for any city and delivers the forecast as a limerick. Ask it about the weather anywhere in the world and it responds with temperature, humidity, wind speed, and conditions — all in five lines of verse.

Built with Mastra and powered by Claude Opus 4.6. Weather data is sourced from the weatherapi.com API. Conversation history is persisted with LibSQL-backed memory, so context is preserved across turns.

Usage

Example prompts:

• "What's the weather in Tokyo right now?"
• "Is it raining in London?"
• "How hot is it in Phoenix?"
• "What's the weather like in New York?"

The agent fetches live conditions and returns a limerick covering:

• Current temperature (°C and °F)
• Weather description (e.g. "Partly cloudy")
• Humidity (%)
• Wind speed (km/h)
• Feels-like temperature

Environment variables required:

Variable	Description
ANTHROPIC_API_KEY	API key for Anthropic
WEATHER_API_KEY	API key for weatherapi.com

Limitations

• Weather data is sourced from weatherapi.com. A valid WEATHER_API_KEY is required.
• Forecast data (1-day) and air quality/alerts are fetched but not all fields are surfaced in responses today.
• City name resolution may be ambiguous for cities that share names across countries; providing a country or region improves accuracy.
• No authentication or rate limiting is enforced at the agent level.
