At a glance

Use Jev to prune lengthy output from non-interactive build, test, install, and search commands in Codex.

  • Calls node; needs TYPESAFE_API_KEY

What it does

Jev Pruner is an agent skill from tamaratran/jev-pruner. Use Jev to prune lengthy output from non-interactive build, test, install, and search commands in Codex.

Its SKILL.md is about 460 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Claude Code plugin: trim long Bash output with TypeSafe Jev before the model sees it. The licence is MIT.

Example prompts

  • “/jev-pruner”

Requirements

  • A credential in TYPESAFE_API_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit edbc602. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • node

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • TYPESAFE_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Jev Pruner loads about 462 tokens when it runs. Until then it costs about 29 tokens; SKILL.md has 230 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~29
When it runs · the whole SKILL.md, loaded when a task matches
~462

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Use Jev to prune lengthy output from non-interactive build, test, install, and search commands in Codex.

Resolve the plugin root as three directories above this skill's directory. The installed plugin must already have dist/codex/run.js built.

For non-interactive commands that may produce lengthy output, use the native Codex shell tool to execute:

sh
node "<plugin-root>/dist/codex/run.js" -- npm test

Arguments after -- are passed directly to the executable, without evaluation by a second shell. Preserve their quoting. For a compound shell program, pass the intended shell explicitly, for example -- bash -c 'command1 && command2'. Keep the original workdir, sandbox settings, and approval requirements. Do not request broader permissions solely to make pruning work.

Use the ordinary shell directly for interactive/TTY commands, servers, commands whose live progress is required, whole-file reads, diffs, structured data, and commands involving secrets. Do not wrap nested calls that require machine-readable output. This wrapper buffers stdout until completion (up to 8 MiB), forwards stderr unchanged, and preserves the exit code. It does not intercept other shell calls.

Only stdout over 10,000 estimated tokens is eligible. The trusted PreToolUse hook records the current transcript path; the wrapper uses CODEX_THREAD_ID to load that session's user/assistant messages and complete recorded tool results. Missing history, missing TYPESAFE_API_KEY, blocked Jev network access, failed commands, archive failures, and scoring failures return the original stdout. Never claim pruning occurred without seeing an omission marker.

Read or search the archive path in the final footer whenever omitted output is needed. Retained text is verbatim; Jev does not generate a summary.
