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 | $0.00026 | $0.00293 |
| Opus 5 | $0.00013 | $0.00147 |
| Sonnet 5 | $0.00005 | $0.00059 |
| Haiku 4.5 | $0.00003 | $0.00029 |
Grade A, and why
energy 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 5d 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
Energy — Umhverfis- og orkustofnun
The Energy Authority publishes downloadable numerical energy tables and a live electricity-indicators dashboard. This source starts with the stable XLSX archive.
Data
Catalogue: https://orkustofnun.is/upplysingar/talnaefni/raforka
OS-2025-1-throun-raforkuframleidslu-a-islandi-1969-2024.xlsx contains the
1969–2024 electricity-generation series by source. It also contains a
guarantees-of-origin table; that describes certificate attribution, not physical
generation.
Usage
uv run python scripts/energy.py list
uv run python scripts/energy.py fetch
Writes data/processed/energy_generation.parquet in long form: year,
series, gwh.
Caveats
- Publication filenames and prefixes change (
OS,UOS,ROS); discover new releases from the catalogue rather than assuming a future URL. - The newest catalogue link can temporarily 404 while the previous release remains live; retain a working-version fallback.
- The source does not state a general reuse licence. Cite the Authority.
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.

energy is a skill published in the GitHub repository jokull/icelandic-data (52 stars, last pushed yesterday), licensed MIT. It adds 26 tokens to every session and 293 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
