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 | $0.02420 | $0.02420 |
| Opus 5.5 | $0.00968 | $0.00968 |
| Sonnet 5.5 | $0.00484 | $0.00484 |
| Haiku 4.5 | $0.00242 | $0.00242 |
Grade A, and why
xweather-agent-skills AGENTS.md 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 27d 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.

Xweather API & Maps — agent skills
This repository packages six Agent Skills for the Xweather developer platform. They are provider-neutral: any skills-compatible agent can load them, and the same content also ships as plugins for Claude Code and OpenAI's ChatGPT and Codex plugin surfaces.
The skills
| Skill | Use it for |
|---|---|
plugins/xweather/skills/weather-api/ |
Building data.api.xweather.com request URLs — every endpoint, all 8 actions, filters, query syntax, and access-cost reporting |
plugins/xweather/skills/raster-maps/ |
Building maps.api.xweather.com URLs — static map images and XYZ tile templates across the full layer catalog, with map-unit cost reporting |
plugins/xweather/skills/mapsgl/ |
The MapsGL JavaScript SDK (@xweather/mapsgl) — controllers, weather layers, styling, expressions, legends, timeline animation, session cost |
plugins/xweather/skills/mapsgl-apple/ |
The MapsGL SDK for Apple platforms — install channels, MapboxMapController/MapLibreMapController, WeatherService.LayerCode layers, SwiftUI and UIKit setup, paint, expressions, legends, timeline, session cost |
plugins/xweather/skills/mapsgl-android/ |
The MapsGL Android SDK (com.xweather.mapsgl) — AAR/JitPack install over the Mapbox Maps SDK for Android, MapboxMapController, LayerCode/WeatherService layers, StyleValue/Expression styling, custom sources and layers, legends and the data inspector, timeline, session cost |
plugins/xweather/skills/webhooks/ |
Pushed data delivery — receiver design, securing the endpoint, retry and idempotency behaviour, registration |
Each skill is a directory with a SKILL.md, plus references/ for detail loaded on demand and
scripts/ for the two helper programs. Read a skill's SKILL.md when a task matches its
description; pull in references/ files only as needed — several are large.
Working in this repository
Never hand-edit the generated reference files. Six are derived from live Xweather sources:
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.
