Optim-Jev：为 Claude Code 打造关注上下文的 Jev 工具套件
Optim-Jev: suite of Jev tools for Claude Code that care about context
Oqura.ai 发布 Claude Code 插件 optim-jev，通过 jev-compacter、jev-router、jev-skills 三个工具减少长会话中的 token 开销。
Spend fewer tokens in long Claude Code sessions—without changing how you work.
Jev-powered context compaction, model routing, and skill selection in one Claude Code plugin.

Why optim-jev?
Long agent sessions accumulate stale tool output, send oversized skill catalogs, and use the main model for work a smaller model could handle. optim-jev reduces that overhead at three points while keeping Claude Code's normal workflow intact.
Each tool works independently, fails open if unavailable, and includes a stats command that reports session-level cost and savings in US dollars.
Three tools, one plugin
| Tool | What it does | Default | Learn more |
|---|---|---|---|
| jev-compacter | Removes stale tool calls and outputs instead of summarizing away the whole conversation | On | Guide |
| jev-router | Routes file changes to the right model using project-specific rules that evolve with your workflow | Off | Guide |
| jev-skills | Sends a short, relevant skill list for each prompt instead of the entire catalog | Off | Guide |
jev-compacter — preserve useful context
It works automatically with /compact and auto-compaction. Inspect the current session with:
/jev-compact stats
jev-router — use the right model for each edit
/jev-route init "what matters in this project"
/jev-route on | off
/jev-route why | stats
Tell Claude to change a preference later—for example, “let haiku edit the tests”—and the project rules update with your workflow.
jev-skills — load only relevant skills
/jev-skills on | off
/jev-skills scope project | global
/jev-skills why | stats | reindex
Quick start
Requirements
- Claude Code with plugin support
- Python 3.10 or newer
- A TypeSafe API key for Jev
Install
git clone https://github.com/Oqura-ai/optim-jev.git claude plugin marketplace add ./optim-jev claude plugin install optim-jev@optim-jev
Set the key in Claude Code under /config → TypeSafe API key, or export it before starting Claude Code:
export TYPESAFE_API_KEY="your-key"
Restart Claude Code. jev-compacter is ready immediately; enable the router and skill picker when you want them. See Getting started for every command, option, and troubleshooting step.
Note
The plugin uses only Python's standard library. Your API key is passed to child processes through the environment and is never written to project files or logs.
