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.

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 | $0.00061 | $0.03643 |
| Opus 5 | $0.00030 | $0.01821 |
| Sonnet 5 | $0.00012 | $0.00729 |
| Haiku 4.5 | $0.00006 | $0.00364 |
Grade A, and why
noaa-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.

NOAA Weather.gov API
The National Weather Service (NWS) API provides free, open access to weather forecasts, alerts, observations, radar data, and more for the United States. All data is public domain — no API key or account required.
Always check the official API documentation and OpenAPI spec for the latest endpoint details.
Base URL
https://api.weather.gov
Authentication
No API key is needed. However, a User-Agent header is required on every request to identify your application.
User-Agent: (myweatherapp.com, [email protected])
The string can be anything — the more unique to your application, the less likely it will be affected by a security event. Requests without a User-Agent may be blocked.
Key Concepts
| Term | Description |
|---|---|
| Point | A latitude/longitude coordinate. Use /points/{lat},{lon} to resolve it to grid and zone info. |
| Gridpoint | A 2.5km forecast grid cell identified by a WFO office ID and x,y coordinates. |
| WFO | Weather Forecast Office — the NWS office responsible for a geographic area (e.g., DEN, OKX, LOT). |
| Zone | A geographic area used for forecasts and alerts. Types include land, marine, forecast, fire, county. |
| Station | An observation station (e.g., KDEN for Denver International Airport) that reports current conditions. |
| Alert | A weather warning, watch, or advisory issued by the NWS (e.g., tornado warning, winter storm watch). |
| SIGMET/AIRMET | Aviation weather advisories for significant or airmen's meteorological conditions. |
| TAF | Terminal Aerodrome Forecast — aviation weather forecast for an airport. |
| GeoJSON | The default response format — standard JSON with geographic feature geometry. |

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

noaa-weather is a skill published in the GitHub repository Outsharp/shipp-skills (4 stars, last pushed 5mo ago), licensed Apache-2.0. It adds 61 tokens to every session and 3,643 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
