Jevkit

Jevkit is a local Go CLI that connects coding agents to TypeSafe AI's Jev service. Agents can use it to classify requests, rank useful lines in noisy output, and ask structured questions. Jevkit redacts configured patterns on your machine before sending text to Jev.

Install

On macOS or Linux, the installer downloads the latest GitHub Release, checks its checksum, and places jevkit in ~/.local/bin:

curl -fsSL https://raw.githubusercontent.com/JoshJancula/jevkit/main/install.sh | sh

On Windows, download the matching ZIP from GitHub Releases or run install.ps1 in PowerShell.

Run jevkit version to confirm the installation. On macOS and Linux, add ~/.local/bin to your PATH if needed. For source builds and development, see the build guide.

Get started

From a project directory:

jevkit key set             # securely store your TypeSafe API key
jevkit key test            # check that it works
jevkit install codex       # or claude, opencode, cursor, antigravity, all
jevkit doctor              # check the local setup

jevkit install adds hooks and an MCP server for the selected agent. Compaction is optional and starts off; set JEVKIT_COMPACT=1 when you want Jevkit to shorten supported tool output. The original output stays available locally. See the agent guide for the supported behavior and settings.

Redaction is pattern based, so check it against your own data before using Jevkit with sensitive output: jevkit redact test --diff <file>. Read the redaction guide for its limits.
