Spawn a new agentproto agent session (claude-code, hermes, ...) with a model, cwd, prompt, and optional MCP tool access. Use when the user says "spawn an agent", "start a session", "launch claude-code on this task", "run hermes in the background", or "kick off a worker". Also covers listing already-running sessions before spawning a duplicate.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Spawn an Agent
## When to use
The user wants a new, independent agent session doing bounded work in a
directory — a worker to delegate to, a background task runner, or a fresh
session for a subtask. Check `agent_sessions_list` first if there's any
chance a matching session is already running; spawning a second one on the
same cwd/task wastes a process.
## MCP tool: agent_start
```json
{
"tool": "agent_start",
"args": {
"adapter": "claude-code",
"model": "claude-sonnet-5",
"cwd": "/Volumes/SSDExternalMacStudio/Code/products/agentik/agentik-studio",
"prompt": "Add input validation to the signup form in apps/agentik/web/src/app/signup — reject empty email and password < 8 chars, add a unit test.",
"label": "signup-validation",
"mcpServers": [
{ "name": "agentproto", "transport": "http", "ref": "http://127.0.0.1:18790/mcp" }
],
"access": { "profileRef": "default" },

How to install
mdr add agentproto/ts/ap-spawn-agent@sha256:bae1b56a6b184c47The line at the top of this page pins the label git:20261009.ab367ec, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
