Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00032 | $0.01376 |
| Opus 5 | $0.00016 | $0.00688 |
| Sonnet 5 | $0.00006 | $0.00275 |
| Haiku 4.5 | $0.00003 | $0.00138 |
Grade A, and why
tekjusagan 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 — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Tekjusagan — "The Income Story" (Prime Minister's Office)
Iceland's most widely-cited public income/inequality tool. Interactive dashboard showing changes in living standards for demographic groups over ~25 years (income, assets, gender, education). Owned by Forsætisráðuneytið; data source Hagstofa Íslands.
Architecture
A thin Angular SPA (tekjusagan.is) that embeds a token-authenticated Power BI report. Unlike public /view?r=... embeds (e.g. landlaeknir), Tekjusagan's Power BI is private — clients fetch a short-lived embed token from Tekjusagan's own backend, then initialize the Power BI JS SDK with that token.
API
| Endpoint | Purpose | Returns |
|---|---|---|
GET https://tekjusagan.is/api/report/04ba62a1-8e38-44bd-a6b0-cb63d1fec3d8 |
Issue a Power BI embed token for the report | {"embedToken": "<1773-char JWT>", "id": "04ba62a1-..."} |
| Field | Value |
|---|---|
| Power BI report ID | 04ba62a1-8e38-44bd-a6b0-cb63d1fec3d8 |
| Power BI group ID | a08a802a-ca7b-4103-9052-18a85d009ec4 |
| Embed container | https://app.powerbi.com/reportEmbed?reportId={id}&groupId={group} |
| DAX endpoint (authenticated) | https://wabi-europe-north-b-redirect.analysis.windows.net/explore/... |
Auth flow: The token is issued without any input credentials (public anonymous endpoint). It scopes access to this one report for the current session. Tokens expire after ~1 hour — re-fetch if a long scrape session is needed.
Dashboard routes (5)
The SPA exposes five Power BI report routes. Each triggers its own DAX queries — drive them via page.goto() rather than clicking menu items (menus only expand the nav tree).
| Slug | Route | Content |

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.
- 6d ago First seen · 100 lines · 32 tokens per session scan A 918f1d288466
tekjusagan is a skill published in the GitHub repository jokull/icelandic-data (52 stars, last pushed today), licensed MIT. It adds 32 tokens to every session and 1,376 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.
