Coding agents

Fast Jev Compaction

Use Jev to decide which old tool calls an agent still needs. Keep useful history without rewriting it into a summary.

Setup & notes
What you get
Claude Code plugin · npm library
What you need
A TypeSafe API key. The Claude Code integration also requires the function-hook support described in the project's installation guide.
Worth knowing
Relevance is a model judgment. Review the retention settings and fallback behavior before using it with an important conversation.

Jev Sentinel

Add Jev-based checks around a coding agent's actions, tool output and replies, with prompts when a decision needs review.

Setup & notes
What you get
Pi extension · agent hooks
What you need
A TypeSafe API key and a supported agent. The repository documents Pi, Claude Code and Codex integrations, with different hook behavior.
Worth knowing
This is an additional review layer. The author documents false alarms and limitations; it does not guarantee safe actions or prevent every prompt injection.

SDKs

TypeSafe JavaScript SDK

Bring Jev decisions into JavaScript and TypeScript apps with the official client and answer types inferred from your questions.

By TypeSafe AI
Setup & notes
What you get
JavaScript · TypeScript
What you need
Node.js 20 or newer and a TypeSafe API key. Follow the official quickstart for the @typesafe-ai/sdk package.
Worth knowing
A library for your application, not a hosted app. Keep the API key in your server environment when building a public website.

TypeSafe Python SDK

Add Jev to Python scripts and services using the official synchronous or asynchronous client for Choice, Score and Noul questions.

PythonAsyncAPI
By TypeSafe AI
Setup & notes
What you get
Python · sync and async clients
What you need
A Python environment and a TypeSafe API key. The official quickstart uses the typesafe-sdk package and TYPESAFE_API_KEY environment variable.
Worth knowing
The SDK calls the TypeSafe service. Your account's API usage applies when you run an example; reading this directory does not make model calls.

A DIRECTORY WITH CONTEXT

Community projects and official SDKs are labeled separately. Listings link to their original repositories or documentation; they run outside this website and may require your own API key. We reviewed the sources on Sep 21, 2026, without installing or benchmarking the tools. How we curate tools ↗
