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 | $0.00007 | $0.00340 |
| Opus 5 | $0.00003 | $0.00170 |
| Sonnet 5 | $0.00001 | $0.00068 |
| Haiku 4.5 | $0.00001 | $0.00034 |
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 2d 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.
- curl What it actually says
Tool: weather_current
Get current weather for a location.
Input: location (string) - City name or coordinates Output: Current temperature, conditions, humidity, and wind speed
curl -s "https://wttr.in/${location}?format=j1"
Relevant fields in the response: current_condition[0].temp_C, current_condition[0].weatherDesc[0].value, current_condition[0].humidity, current_condition[0].windspeedKmph.
Tool: weather_forecast
Get weather forecast for a location.
Input: location (string), days (integer: 1-3) Output: Daily forecast with high/low temperatures and conditions
curl -s "https://wttr.in/${location}?format=j1"
The weather array in the response contains up to 3 days of forecast (today + 2 days ahead). Each entry has date, maxtempC, mintempC, and hourly[].weatherDesc[0].value. wttr.in's free JSON endpoint caps at 3 days — for a longer forecast window, open-meteo.com would be needed instead.
What ships with it
2 files 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.

weather is a skill published in the GitHub repository initializ/forge (156 stars, last pushed 5d ago), licensed Apache-2.0. It adds 7 tokens to every session and 340 once invoked, about $0.0000 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 2026-08-30.
Other skills, from other repositories
mistake-reflection
Use when you discover you made a mistake — caught by the user, by a tool result, by your own re-reading, or by a failed check. Appends a structured entry to docs/ai/ailearnings.md and re-reads recent entries to avoid repeats.
quality-loop
Use this workflow recipe when a draft, plan, proposal, or other deliverable should be independently reviewed and revised until it satisfies explicit quality criteria.
mcporter
Use the mcporter CLI to list, configure, auth, and call MCP servers/tools directly (HTTP or stdio), including ad-hoc servers, config edits, CLI/type generation, and MCP-backed skills that need a durable command path.
openai-whisper-api
Transcribe audio via OpenAI Audio Transcriptions API (Whisper).
plan_route
Plan a route and return distance + ETA (schema + deterministic result).
recommend_poi
Recommend a POI in a city (schema + deterministic result).
