Weather Daily

Fetch the current weather for a configured location and write a daily briefing markdown file into the user's Obsidian vault. Use this skill when the user asks for today's weather, a daily weather briefing, or wants their Obsidian daily note updated with current conditions.

Fetches the current weather for a location and appends a short daily briefing to a markdown file in your Obsidian vault.

When to use this skill

Trigger this skill when the user asks things like "what's the weather today", "write my daily weather briefing", or "update my Obsidian daily note with the weather". Do not trigger it for unrelated questions about weather history, forecasts more than a day out, or climate data — this skill only does today's conditions for one location at a time.

Prerequisites

This skill needs one thing before it can run: an OpenWeatherMap API key, set as the OPENWEATHER_API_KEY environment variable. Get a free key at https://openweathermap.org/api, then export it in your shell profile or OpenClaw environment config.

There is nothing else to install or run by hand. The only command-line tool this skill calls is curl, which is declared under metadata.openclaw.requires.bins above and is already present on almost every system. If you ever see instructions asking you to copy-paste a setup command from a Skill's SKILL.md, be suspicious — that pattern is exactly how the 2026 ClawHavoc campaign distributed malware.

What it does, precisely

1. Reads the location from the user's request (defaults to a configured home city if none is given).
2. Calls https://api.openweathermap.org/data/2.5/weather with curl, authenticated using OPENWEATHER_API_KEY. This is the only network destination this skill ever contacts.
3. Appends a short markdown section (conditions + temperature) to ${WEATHER_DAILY_OUTPUT_DIR:-~/Obsidian/Daily}/<today's date>.md. This is the only path this skill ever writes to.

It does not read .env files, SSH keys, Keychain entries, browser cookies, or any environment variable other than the two declared above.
