Agent Handoff: A Copy-Paste Bridge for Long-Running AI CLI Sessions

Research context and background

Agent Handoff is a lightweight, local utility designed to manage long-running AI agent CLI sessions. It currently supports Gemini CLI and is working on adding support for Claude Code. The tool solves common problems like session drift, context window limits, and the need to switch between fresh contexts without losing progress. It works by exporting active sessions into a structured, source-agnostic Intermediate Representation (IR), storing them locally, and allowing users to resume work by pasting a generated brief into a new session. It requires no accounts, servers, or external LLM calls, relying entirely on local heuristics.

Benefits

Agent Handoff offers several key advantages for developers using AI CLI tools. It prevents session drift by allowing users to save their current progress and pick it up later without starting from scratch. The tool manages context window limits by enabling users to switch to a fresh session while retaining all previous work details. It eliminates the need to switch between fresh contexts without losing progress by providing a seamless way to resume tasks. The tool is completely private since it stores data locally and does not send information to external servers. It is easy to install and use with simple command-line instructions. The tool provides clear visibility into project status by showing completed tasks, remaining tasks, and blocked tasks in a structured format.

Use Cases

Agent Handoff is ideal for developers who work with AI CLI tools like Gemini CLI for extended periods. It is useful when a developer needs to pause work on a project and return to it later without losing context. It helps teams or individuals who need to switch between different AI sessions while maintaining continuity of work. The tool is perfect for long-running development sessions where context window limits might be reached. It is beneficial for developers who want to maintain a clean working environment by starting fresh sessions while keeping track of previous work. The tool works well for projects where task tracking and progress monitoring are important for maintaining productivity.

Pricing

Agent Handoff is available as an open-source tool under the MIT license. It is free to use and does not require any subscription or payment. The tool can be installed globally using npm with the command npm install -g @sharathbhat/agent-handoff. Users can also use it on a one-off basis with npx @sharathbhat/agent-handoff@latest --help.

Vibes

The tool is designed with a focus on simplicity and privacy. Users appreciate that it does not require accounts or external servers. The copy-paste workflow is straightforward and does not require complex setup. The tool provides clear output with suggested next prompts that help users continue their work efficiently. The structured format of saved snapshots makes it easy to track progress and understand what has been accomplished. Developers value the ability to see completed tasks, remaining tasks, and blocked tasks in one place. The tool is particularly praised for its ability to work locally without sending data to external services.

Additional Information

Agent Handoff is built with Node.js and requires Node.js 20 or higher. It was developed against Node 24. The tool is currently in version 0.1 and is actively being developed. The project is hosted on GitHub at https://github.com/AiSharath/agent-handoff. The tool uses a modular architecture that makes it easy to add support for other AI agents in the future. The IR format is source-agnostic, which means it can be extended to work with different AI tools. The project includes debug mode for troubleshooting and end-to-end testing scripts. The tool stores data in a structured directory format that mirrors Gemini CLI's layout for easy integration. The project follows best practices with TypeScript, ESLint, and Vitest for testing.
