Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00007 | $0.00202 |
| Opus 5 | $0.00003 | $0.00101 |
| Sonnet 5 | $0.00001 | $0.00040 |
| Haiku 4.5 | $0.00001 | $0.00020 |
Grade A, and why
weather scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
bins: [curl] What it actually says
Weather
Get weather information using wttr.in.
Usage
- Current weather:
curl -s "wttr.in/CityName?format=3" - Detailed forecast:
curl -s "wttr.in/CityName" - One-line summary:
curl -s "wttr.in/CityName?format=%l:+%c+%t+%w+%h" - Moon phase:
curl -s "wttr.in/Moon"
Replace spaces in city names with + (e.g., New+York).
For JSON output: curl -s "wttr.in/CityName?format=j1"
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.
