Weather

What it does

When your agent uses it

• The user asks about weather
• A weekly forecast for a place

Example prompts

• “Use the weather skill to fetch current weather conditions and a 7-day forecast for a requested location using Open-Meteo geocoding and forecast APIs”
• “/weather”

Requirements

• Python 3
• Pre-approved tools (allowed-tools): python

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

1. 1Activate the skill documentation with skill.activate("weather") if it is not already active.
2. 2Fetch the live weather JSON with skill.runScript("weather", "scripts/get_weather.py", [...args]).
3. 3Summarize the returned JSON for the user, explicitly calling out the current conditions and the 7-day forecast.

What it can do on your machine

Read from SKILL.md and the folder at commit 0fdba82. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • python

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Ships 1 file in scripts/ (Python), which the agent can run.

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Weather loads about 1k tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 278 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~58

When it runs · the whole SKILL.md, loaded when a task matches

~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
