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 | $0.00025 | $0.00307 |
| Opus 5 | $0.00013 | $0.00153 |
| Sonnet 5 | $0.00005 | $0.00061 |
| Haiku 4.5 | $0.00003 | $0.00031 |
Grade A, and why
aircraft-register 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 11d 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
Aircraft Register
Access
- Data page:
https://www.transpordiamet.ee/ohusoidukite-register - Method:
GET - Response: server-rendered HTML; no public JSON endpoint is documented.
Retrieve
- Fetch the data page and locate the table containing
Registration markandType of the Aircraft. - Read the update date and total from the table's first row.
- For each aircraft row, use physical cells 2, 5, 6, 7, and 8 (one-based). The other cells are empty layout columns.
- Normalize whitespace, including non-breaking spaces, but preserve identifiers and names.
Return:
registration_markaircraft_typeserial_numberowneroperatorregister_update_datesource_url
Limits
- This is a complete published table, not an identifier search API.
- Owners and operators may be
eraisik(private person); do not infer a hidden identity. - The update date is written as
DD.MM.YYYY/updated, without aRegister seisugalabel.
Verify
Require the five bilingual column labels, a date matching DD.MM.YYYY/updated, and multiple registration marks beginning ES - after whitespace normalization.
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.

aircraft-register is a skill published in the GitHub repository taivop/marketplace (17 stars, last pushed 11d ago), licensed MIT. It adds 25 tokens to every session and 307 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.
