> So I built Pensieve. It's a local index of your code, documents, and past agent sessions. Any agent can query it over MCP and get the few files that matter on the first try

What are the various ways Pensieve is superior to iterative grep? Is it just better "semantic" search instead of literal "grep"?

Cache invalidation is hard - how does Pensieve address it?

Your site says "Pensieve watches your folders, repos and agent sessions and re-indexes what changed. Uncommitted edits count, and every worktree is tracked by branch, so your agents never work from stale context." but you don't define what "stale context" is - if I'm exploring 3 different implmentations of the same concept across 3 different branches, which one is the "stale context"?

Could you take a few minutes to explain the what and the how? Links to writeup to blog posts or files in your repo would be very helpful.

Finally, can I use Pensieve with Paseo? What if I wanted to expose Pensieve's capability to my Paseo setup?
