air_quality is a skill for Claude Code from nikhilreddy3888/public-api-toolkit. It costs 35 tokens per session (194 once invoked), scanned A, original, MIT.

A skill for getting air-quality information from WAQI, the World Air Quality Index service. It can use a city or geographic coordinates and returns the air-quality index, pollutant levels, and advice.

In plain words
What is it for?
Use it to check pollution levels and air quality for a city or location, including PM2.5, PM10, ozone, and nitrogen dioxide.
Why use it?
It avoids having to find, call, and interpret the air-quality service manually. The free demo access has usage limits.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

air_quality scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
