jev-pruner A Claude Code plugin that uses TypeSafe's Jev to trim noisy Bash output after the command runs, but before its result is sent back to the main LLM. This reduces the output carried into later turns without generating a summary. Using Codex? See Codex installation and usage. A hook wraps the Bash tool's result. Stdout of 10,000 estimated tokens or fewer passes through untouched, without reading history, writing an archive, or calling Jev. The gate uses on raw stdout, not a character count or an exact model tokenizer. can raise this threshold but cannot lower it. If Claude already saved the output to a file, the hook reads and counts that full output instead of its short preview. Errors, JSON/XML/YAML/diff/binary output, whole-document commands (, , , , , and ) are left untouched. Output is split into chunks of lines, capped at 200 chunks; lines longer than 2,000 characters are split first. Jev receives , plus and for recognized build/test/install or search/excerpt commands, and one noul question per chunk: “does any line in this chunk need to remain available?”. A single needed line protects the chunk, includin

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy, covering 11 red-flag categories including credential harvesting, data exfiltration, and curl | sh installers. It is a first-layer scan, not a manual audit — we say so rather than overstate it.
The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
