What it tells the agent

The instruction file, verbatim from the audited commit — this is the text the model reads, and the surface the audit's instruction layer examines. Quoted here so you can judge it without cloning anything.

# Weather

Two free services, no API keys needed.

## wttr.in (primary)

Choose one request that matches the user's scope. Do not fetch current
conditions separately when a today or forecast request already includes them.

Platform notes:
- On Windows PowerShell, use `curl.exe`; bare `curl` may resolve to
  `Invoke-WebRequest`.
- On macOS and Linux, use `curl`.

Current conditions only:
```bash
curl -s "https://wttr.in/London?format=3"
# Output: London: ⛅️ +8°C
```

Custom current conditions format:
```bash
curl -s "https://wttr.in/London?format=%l:+%c+%t+%h+%w"
# Output: London: ⛅️ +8°C 71% ↙5km/h
```

Today's weather, including current conditions (use this single request for
questions about today's weather):
```bash
curl -s "https://wttr.in/London?1&m"
```

Full forecast:
```bash
curl -s "https://wttr.in/London?T&m"
```

On Windows PowerShell, replace `curl` with `curl.exe` in the commands above.

Format codes: `%c` condition · `%t` temp · `%h` humidity · `%w` wind · `%l` location · `%m` moon

Tips:
- URL-encode spaces: `wttr.in/New+York`
- Airport codes: `wttr.in/JFK`
- Units: `?m` (metric) `?u` (USCS)
- Today only: `?1` · Current only: `?0`
- PNG (macOS/Linux): `curl -s "https://wttr.in/Berlin.png" -o weather.png`
- PNG (Windows PowerShell): `curl.exe -s "https://wttr.in/Berlin.png" -o weather.png`

## Open-Meteo (fallback, JSON)

Free, no key, good for programmatic use:
```bash
curl -s "https://api.open-meteo.com/v1/forecast?latitude=51.5&longitude=-0.12&current_weather=true"
```

Find coordinates for a city, then query. Returns JSON with temp, windspeed, weathercode.

Questions

What does the Weather skill do?

Ultra-lightweight, open-source, self-hosted personal AI agent framework in Python with WebUI, tools, memory, MCP, multi-agent workflows, automation, and chat apps

Is Weather safe to install?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean skill reads B.

What can Weather access on my machine?

The audit observed no filesystem, network or shell use at all in its source.

How current is this page?

The grade is for one exact copy of the source (59e883b22cc8), read on 2026-09-29. The repository is watched, and a new audit runs when it changes — this is the first audit.
