Yilabsai Houyiagent Weather

Weather Skill

Provides weather-related query capabilities with two input modes and provider fallback.

Tools

get_date

Get current date or calculate date with offset.

Parameters:

• offset_days (int | str, optional): Days to offset, or relative string like "today", "tomorrow", "yesterday"

Returns: ISO format date string (YYYY-MM-DD)

Examples:

get_date()           # Returns today's date
get_date(1)          # Returns tomorrow's date
get_date(-1)         # Returns yesterday's date
get_date("tomorrow") # Returns tomorrow's date

get_weather

Get weather by coordinates or city name.

Parameters:

• lat (float, optional): Latitude coordinate (-90 to 90)
• lon (float, optional): Longitude coordinate (-180 to 180)
• city (str, optional): City name (friendly mode)
• country (str, optional): Country/region disambiguation for city mode
• date (str, optional): ISO date string or relative string like "today", "tomorrow"
• provider (str, optional): auto (default), openmeteo, or wttr

At least one mode is required:

• Coordinates mode: provide both lat and lon
• City mode: provide city

Returns: Human-readable weather summary

Example:

get_weather(lat=39.9042, lon=116.4074, date="today")
# Open-Meteo date-aware forecast

get_weather(city="Hangzhou", date="today")
# City mode (internally resolves coordinates first)

get_weather(city="London", provider="wttr")
# Current weather summary from wttr.in

Lifecycle Hooks

This skill registers default hooks that users can extend:

• PreToolUse: Validates dual-mode input contract (lat+lon or city) and coordinate ranges.
• PostToolUse: Logs a summary of the weather result. Output is injected into the prompt for downstream use.

Data Source

• Open-Meteo — structured forecast (date-aware)
• wttr.in — compact current-weather text summary

Agent Execution Contract

When an AI Agent needs to execute this skill, use the following workspace-agnostic command. Replace the placeholders with actual values (use None for missing values, strings must be quoted).

uv run python -c "from houyi.skills.weather import get_weather; print(get_weather.executor(lat={LAT}, lon={LON}, city={CITY}, country={COUNTRY}, date={DATE}, provider={PROVIDER}))"

Example:

uv run python -c "from houyi.skills.weather import get_weather; print(get_weather.executor(lat=None, lon=None, city='Hangzhou', country=None, date='today', provider='auto'))"
