    Because the LLM inference makes airgapping infeasible right?

    We’re working on adding native support for Shelley! The idea is that even with native recall from Shelley, ctx results are more accurate, ergonomic, and token efficient For example…

    Very cool! Do you have any of it OSS? Or drop me an email: luca@ctx.rs

    It's all in the skill / instruction that you give to the agent. The agent should treat the history as anthropology - a record of what happened, not necessarily the ground truth. Cr…

    Thanks and this is a very interesting idea! We considered this, but the main thing you gain from this tradeoff is some disk space and cleaner retention semantics from not having to…

    Nice, yea I typically spend about 1/3 of my sessions on finding ways to improve the agents' SDLC. Lots of random audits and things. And yea on the import thing, there are quite a f…

    Lol fair enough! Great project btw. Interesting choice to trigger incremental refresh on SessionStart hook, that's nice. How have you enjoyed the semantic search?

    This is true, maybe we could reword it to be less absolute. The bigger point is that when they do go spelunking in the old session logs, it is extremely token inefficient, and you …

    This is likely true, but ultimately this tool is just SQL, which I believe Claude and others must be heavily RL'd on. We try to not do anything "special" and make it boringly SQL r…

    Yes this is how we started as well! At first I thought the main improvement would be that the search would be faster, but rg is already pretty freakin fast when the fs cache is war…

    Building this made it obvious that there should be a standard format / specification for agent transcripts and logs (similar to ACP for runtime events). If you're interested in dis…

    Show HN: ctx – Search the coding agent history already on your machine

    Coding agents don't have long-term memory. But you do have months of full-fidelity agent transcripts stored on your machine. A simple solution that goes a long way: ingest those tr…

    Hi HN, OP here. We posted here back in April and the most common request was to make the source code public. As of today, ctx is now open-source: https://github.com/ctxrs/ctx ctx i…

    I’ve had lots of inconsistent app reviews from Apple. Just appeal and/or re-word your language and you’ll be ok. Plan on it taking a few weeks to fully sort out.
