A pantograph extension that keeps the provider's prompt cache warm while you're idle by periodically sending a small throwaway prompt, which is never added to the context window or the transcript. https://code.tjp.lol/panto-warming.git/atom?h=v0.2.0 2026-09-25T21:11:20Z 2026-09-25T21:11:20Z t t@tjp.lol 2026-09-25T20:58:55Z urn:sha1:8da8849e71a8dac7ed81d45d7674e6a3f38cbb7c Send a minimal transient prompt on idle intervals to keep the provider-side prompt cache warm, then discard prompt and response so the context window and transcript stay untouched.
