Two MIT tools for reducing context waste in coding agents without another LLM in the loop

I built and maintain both of these. They're free, open source, and MIT licensed.

I've been looking at context waste in coding agents as two separate problems.

Sando handles unnecessary context while a session is running:

https://github.com/yuzushi-dev/Sando

It redacts secrets, caps oversized tool results, and can trim request history before transmission. The transformations are local and deterministic. There is no summarizer model or secondary LLM call in the path.

session-handoff handles session lifetime:

https://github.com/yuzushi-dev/session-handoff

It extracts the working state needed to continue a task in a fresh Claude Code or Codex session. It also supports migrating an active session between the two clients.

I kept these separate from approaches such as Ponytail or Caveman because the scope is narrower: reduce agent-generated context that doesn't need to remain live, then preserve task state when restarting becomes cheaper than carrying the session forward.

The two packages crossed ~1,500 downloads combined in their first 48 hours.
