Agent Soul Transfer Protocol (ASTP)

English | 简体中文

Portable AI agent persona, identity, work principles, and safety protocol transfer system.

Background

Because I encountered situations where the entire tool failed to start and respond after updating some agents, especially those that are updated frequently. Each update often includes many "improved" items. For the sustainability of work, I had to consider the possibility of backup, restoration, and transfer. Simultaneously accommodating the necessity of transfer in case of hardware damage. Not just work results, but also the "tacit understanding" accumulated over a long period of working with agents — saving prompt definitions, safety boundary principles, coding standards, thinking paths, etc.

So initially, I planned to develop a whole set of manually configured architectures to guide this backup and transfer process via human instruction. Later, I thought, why not let the agents themselves agree on a universal transfer specification? After conducting multi-round discussions among three agent tools (opencode, claude code, openclaw) and undergoing my personal modifications, this set of transfer "specifications" was formed.

Introduction for AI Agents

This project currently uses pure MD documents as explanations and specifications during the transfer process. When needing to package yourself, please read packys_en.md. When needing to receive transfer files and update yourself, please read adaptys_en.md.

It is necessary to explain and summarize the functions in the project files and the upcoming actions to your users before taking any action. If permission is granted to execute, strictly follow the instructions in the files; if not permitted, do not arbitrarily take any actions to delete your own rule files or work files.

Install & Build

This project is not yet published as a package. Build and run directly from source.

Prerequisites

• Node.js >= 20
• npm or pnpm
• SSH key-based auth to source/target hosts (for remote sessions)

Build from Source

git clone https://github.com/tatuke/agent-switch.git
cd agent-switch
npm install
npm run build

After building, the CLI executable is at dist/main.js.

Link Globally (Optional)

npm link
astp <command> [options]

Usage

astp transport — End-to-end transfer wizard

The core command. Walks you through configuring source and target, then automatically:

1. SSHs into the source host
2. Launches the source agent in pipe mode to execute packys packing
3. Collects the bundle as a zip
4. Transfers to the target host (or saves locally)

astp transport

On start, choose a mode:

Wizard steps:

• Step 0: Choose mode (save locally / transfer)
• Step 1-4: Configure source agent, SSH endpoint, pack path
• Step 5-6: Configure target (skipped in save-locally mode)
• Step 7: Connectivity test
• Step 8: Preview and confirm
• Step 10-12: Execute: SSH session → pack → zip → collect → transfer

astp transport --save-locally — Backup mode

Skip all target configuration. Pack from source and save the zip locally.

astp transport --save-locally \
  --source-agent openclaw \
  --source-host user@source-host \
  --source-path /path/to/.astp-bundle

astp transport — Full transfer with flags

Skip wizard steps by providing flags directly:

astp transport \
  --source-agent openclaw \
  --source-host user@source-host \
  --source-path /path/to/.astp-bundle \
  --source-port 22 \
  --target-agent claude-code \
  --target-host user@target-host \
  --target-path /path/to/target-bundle \
  --target-port 22 \
  --skip-check

astp transport --plan — Resume from saved plan

Re-run a previously saved transport plan:

astp transport --plan ~/.astp/transfers/openclaw-to-claude-code-2026-04-27.yaml

All transport flags

--source-agent <name>      Source agent name (skips Step 1)
--source-host <user@host>  Source SSH target (skips Step 3)
--source-path <path>       Source bundle path (skips Step 4)
--source-port <port>        Source SSH port (default: 22)
--target-agent <name>      Target agent name (skips Step 2)
--target-host <user@host>  Target SSH target (skips Step 5)
--target-path <path>       Target bundle path (skips Step 6)
--target-port <port>       Target SSH port (default: 22)
-o, --output <path>        Output path for saved transport plan
--skip-check               Skip connectivity and path validation
--plan <path>               Execute from saved plan file (skip wizard)
--save-locally              Backup mode: pack and save locally, no target needed

astp bundle — Validate a bundle directory

astp bundle --input .astp-bundle
astp bundle --input .astp-bundle --inject claude-code

astp validate — Validate a soul YAML file

astp validate ./soul.yaml

astp list — List available souls
