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 | $0.00043 | $0.04264 |
| Opus 5 | $0.00022 | $0.02132 |
| Sonnet 5 | $0.00009 | $0.00853 |
| Haiku 4.5 | $0.00004 | $0.00426 |
Grade A, and why
sedlabanki 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 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Seðlabanki Íslands (Central Bank of Iceland)
Monetary and financial statistics: interest rates, balance sheets, and new credit.
Important: Both sedlabanki.is and gagnabanki.is are JavaScript SPAs (Blazor / Angular). Simple HTTP fetches return empty HTML shells. Use Playwright for data extraction.
Data Scope
Three core datasets covering Iceland's monetary system:
0. Key Interest Rates (Meginvextir Seðlabankans)
Type: Daily observations Period: Jan 2007 - present (18+ years) Frequency: Daily (business days)
Central Bank policy rates:
- Meginvextir / Key rate (7-day term deposit rate) — the main policy rate since 2014
- Vextir á daglánum / Overnight lending rate
- Vextir á viðskiptareikningum / Current account rate
- Also: 7-day collateralised lending, 28-day CBI CDs, REIBOR rates
Source: gagnabanki.is Power BI embed (report key: interests)
Data Portal: gagnabanki.is
The Central Bank's data portal at gagnabanki.is is an Angular SPA wrapping Power BI reports.
Architecture:
- Config API:
GET https://gagnabanki.is/api/config— returns all report IDs, time series keys, filters - Embed token:
GET https://gagnabanki.is/api/embed/{groupId}/{reportId} - Group ID:
05060786-7f48-4442-8981-314b262d68a7 - Data flows through Power BI's WABI backend (
*.pbidedicated.windows.net)

Extraction method: Playwright intercepts Power BI querydata responses from *.pbidedicated.windows.net. Data arrives in DSR (DataShapeResult) format with compressed values.
# Fetch interest rates to CSV
uv run python scripts/sedlabanki_rates.py
# Output as JSON
uv run python scripts/sedlabanki_rates.py --json
Output: data/processed/sedlabanki_rates.csv with columns: date, series, value
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.

sedlabanki is a skill published in the GitHub repository jokull/icelandic-data (52 stars, last pushed yesterday), licensed MIT. It adds 43 tokens to every session and 4,264 once invoked, about $0.0002 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.
