JevTO: smaller command-output views, with exact recall
An experimental open-source tool that trims command output for Claude Code and other coding agents while preserving the original output for later retrieval.
- For
- Developers using Claude Code or other coding agents
- Worth noticing
- Its benchmark page separates output reduction from session-input savings, reporting 94% across 23 scenarios versus 9% median in a three-run Codex test.
Field notes
Commands run with the user's permissions, and JevTO stores stdout, stderr, and exit status separately in a local store. Its rules recognize selected test and build-output patterns, protect listed failure signals, and mark deferred sections for retrieval; if a view would not be smaller, the original is delivered unchanged. The page distinguishes a 94% rules-only estimate across 23 scenarios from a 9% median session-input reduction in a three-run Codex test, and notes that output reduction is not measured bill savings.
