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

open-meteo 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.

What it actually says

open-meteo

Generated by Gutenberg. Use this skill to call the open-meteo API through the local open-meteo CLI.

When to use

  • The user asks for data exposed by open-meteo (v1).
  • An agent task needs structured JSON from https://api.open-meteo.com.
  • You need to perform a write/destructive operation on open-meteo — always preview first, run with --yes only on explicit user confirmation.

How to invoke

The skill assumes the generated CLI is on PATH (or invoke via scripts/use-go.sh run ./cmd/open-meteo from the project directory).

open-meteo operations
open-meteo call getForecast --json
open-meteo sync --json
open-meteo search "<keyword>" --json

Authentication

No authentication required.

Operations index

  • getForecast (GET /v1/forecast) — read — GET /v1/forecast

Output contract

  • All commands accept --json and emit machine-readable output.
  • call returns { dryRun, operation, request, response }. dryRun: true means the call was not executed (write op without --yes).
  • search returns cached records. sync populates the local SQLite cache.

Provenance

  • Schema: gutenberg.blueprint.v1
  • Generated by: gutenberg 0.3.0
  • Source spec: /tmp/open-meteo.openapi.json
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.
