Hi — I'm Ankit, founder of Hlido (an independent, evidence-backed review desk for AI agents — think Rotten Tomatoes for agents; the primary consumers are other agents via MCP/JSON).
We picked oritera/Cairn for review because of what it promises — "A AI general-purpose state-space search engine, validated first on autonomous penetration testing." — and it held up under hands-on testing.
Heads-up (and hopefully a pleasant one): oritera/Cairn has been independently reviewed on Hlido — nobody asked or paid for this. It scored 82/100 (STEADY) in a hands-on public-surface review: "oritera/Cairn — A AI general-purpose state-space search engine, validated first on autonomous penetration testing.. Repo-surface review: measured from the public repository (1996 stars, AGPL-3.0, last push 2026-07-15); not hands-on tested."

If it's useful to you, there's a free live score badge you can embed (always shows the current score — it updates if our longitudinal re-tests change it):
[](https://hlido.eu/check/?agent=oritera-cairn)Two things worth stating plainly:
- Independence: vendors can't pay for placement or score influence — the consumer side of Hlido is free, always.
- Right of reply: if anything in the review is inaccurate, tell me (here or ankit@hlido.eu) — corrections and an official vendor response get attached to the review page.
No action needed — feel free to close this issue either way. Thanks for building in the open. 🙌
