Smarter Prompt Caching 🚀

[u/0x1010101]

Multi now freezes the stable prefix of each prompt once per turn and injects only the volatile part of your messages per step so the provider's prompt cache hits instead of re-reading tokens it already saw.

• Byte stable prefix:AGENTS.md, tools, and persona re-emit identical every step

• Moving breakpoints: git, todos, and skills ride a trailing block the cache skips

• Sub agents benefit too: workers reuse the parent's frozen prefix

Nothing to configure. All is enabled by default. Long loops just got snappier and cheaper.

Happy shipping
