You are paying for stale context

01

Context accumulates with each request

Old errors, superseded plans, files you finished with: context keeps piling up.

Much of it goes stale

As sessions progress, bugs get fixed, plans get replaced and files get rewritten.

Stale costs compound through the session

Model routing and prompt caching mitigate the symptom but not the root cause.

…because no one manages context lifecycle

Agents never clean up stale context.

If processes handled memory the same way.

Useful information is preserved in context. Paginated information is recalled on demand.

Vachi preserves quality

We validated that output quality remains unchanged across several benchmarks.

Removing stale context mitigates bad outcomes

Driven by improved signal to noise ratio.
