What it does

Weather is an agent skill from DrugClaw/DrugClaw. Get current weather and short forecasts quickly using wttr.in (no API key required). Use when users ask for weather by city/region.

Its SKILL.md is about 180 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: {"deps":["curl"]}

It sits in Research & Science. The repository describes itself as: 💊 AI Research Assistant for Accelerated Drug Discovery. 🦞.

When your agent uses it

  • Users ask for weather by city/region

Example prompts

  • “/weather”

Requirements

  • Compatibility (from SKILL.md): {"deps":["curl"]}

What it can do on your machine

Read from SKILL.md and the folder at commit 960a6e0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl

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

  • Network

    No URLs in SKILL.md. Its commands use curl, which can reach the network depending on how they are called.

    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.

  • Compatibility

    {"deps":["curl"]}

    From compatibility in the SKILL.md frontmatter.

Context cost

Weather loads about 178 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 38 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~35
When it runs · the whole SKILL.md, loaded when a task matches
~178

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

Auto-check passed

The automated check found no risky patterns in SKILL.md.

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); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Proprietary) doesn't allow us to republish the file, so here is its outline and opening line. It has 38 words (~178 tokens).

“Use this skill for quick weather lookups without API keys.”
