A search tool for rental homes listed on boligportal.dk, a Danish housing website. It turns everyday requests into filters for Danish cities, prices, sizes, and other listing details.

Finding apartments and other rentals in Denmark, checking for new listings, and keeping track of which listings have been seen.

It removes the need to search the site manually or know its filter terms. It can also help distinguish new listings from homes already reviewed.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00063	$0.01872
Opus 5.5	$0.00025	$0.00749
Sonnet 5.5	$0.00013	$0.00374
Haiku 4.5	$0.00006	$0.00187

Security

Grade A, and why

bolig-watch 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 2mo 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.
