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 | $0.00031 | $0.02903 |
| Opus 5 | $0.00015 | $0.01452 |
| Sonnet 5 | $0.00006 | $0.00581 |
| Haiku 4.5 | $0.00003 | $0.00290 |
Grade A, and why
kortagerd 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 6d 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.
How it starts
The opening of the file, as written. The whole thing — 263 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Kortagerð (Mapmaking) — Iceland Maps
Generate high-quality maps of Iceland using cached LMI geodata. Supports interactive HTML (Leaflet) and static PNG/SVG (geopandas + matplotlib).
Quick Start
# Ensure geodata is cached
uv run python scripts/lmi.py download
# Interactive map (full-screen, layer toggles, popups)
uv run python scripts/kortagerð.py html -o reports/map.html
# Static map (publication-quality PNG)
uv run python scripts/kortagerð.py static -o reports/map.png
# Zoomed to capital area with Reykjavík highlighted
uv run python scripts/kortagerð.py static --bounds capital --highlight "Reykjavíkurborg" -o reports/rvk.png
# Overlay custom points from CSV
uv run python scripts/kortagerð.py static --points data/my_locations.csv -o reports/custom.png

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.

kortagerd is a skill published in the GitHub repository jokull/icelandic-data (52 stars, last pushed yesterday), licensed MIT. It adds 31 tokens to every session and 2,903 once invoked, about $0.0002 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.
