How does AgentREPL ensure security?

It uses STDIO (standard input/output) transport, meaning no network port is opened. This enhances security, making it registry eligible and safer for agent workflows.

Can I manage Julia packages and projects with AgentREPL?

Yes, AgentREPL offers comprehensive `pkg` tools for `add`, `rm`, `test`, `develop`, and an `activate` tool to dynamically switch Julia project environments.

What problem does AgentREPL solve for AI agents?

AgentREPL eliminates Julia's 'Time to First X' (TTFX) overhead. AI agents like Claude Code get persistent Julia sessions, avoiding slow startup and compilation for each command.

What makes AgentREPL different from similar tools?

AgentREPL is optimized for autonomous AI agent execution (Claude → Julia), offering persistent STDIO sessions, auto-spawning, and true hard resets, unlike human-in-the-loop or Julia-to-Claude SDKs.

What is a 'true hard reset' and why is it important?

A true hard reset kills and respawns a worker subprocess, providing a complete clean slate for the Julia session. This allows type redefinitions and clears all state without restarting the main AI agent.

Provides a persistent Julia REPL session for AI agents, eliminating Time to First X (TTFX) overhead.

概要

AgentREPL addresses Julia's significant 'Time to First X' (TTFX) problem, which traditionally causes AI agents to waste valuable compute time on process startup and JIT compilation with every command. It offers a persistent Julia REPL session specifically designed for AI agents, utilizing the Model Context Protocol (MCP) via STDIO transport. This ensures that the Julia process remains alive, incurring TTFX costs only once, and allows for advanced features like true hard resets (via a worker subprocess model) for type redefinitions, and modern Julia package management workflows. AgentREPL is highly integrated with Claude Code through a dedicated plugin, providing auto-configuration, convenient slash commands, and best practices for seamless AI-driven Julia development.
