Command compression that proves it helped.

Boost measures task success, preserves recovery, and learns from every rollback.

The short answer

Compression ratio is not the outcome

Boost measures whether agents still finish the work.

The Boost advantage

Why Boost is the better command-output choice

All four reduce tokens, but at different layers. RTK compresses commands, Headroom compresses the wider context stream, and Caveman shortens assistant replies. Boost stays at the command boundary and adds a measurable safety loop: preserve requested detail, recover hidden output, learn from every retrieval, and verify that agents still complete the task.

Approval safety compares whether the host sees the original executable. RTK separately evaluates host permission rules before rewriting.

The honest summary

Does better
Task-level proof, native approval visibility, versioned rollback learning, and OTLP evidence.
Also does
Flag-aware command compression and raw-output recovery.
Does not do
RAG or full-context compression, or shorter assistant replies.

When you do not need Boost

Skip it if your agent rarely runs shell commands or your main problem is verbose replies.

Data, telemetry, and preview status

Redacted originals stay local. Boost sends product telemetry to JFrog under the Preview Agreement. External OTLP export is optional.
