Quick Start

Spawn a new session for a chosen agent with an initial prompt and a defined scope.

Frequently Asked Questions about sessions-spawn

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
What is a scoped contract for sub-agent delegation?▼

A scoped contract restricts a sub-agent's execution boundaries by enforcing access controls and isolation rules within a sandboxed environment. This mechanism ensures delegated tasks operate securely without exceeding their defined permissions or compromising the parent workflow.

How do I spawn a sub-agent session with an initial prompt?▼

You spawn a sub-agent session by selecting an agent type—such as coder, media, or custom—and providing an initial prompt alongside a defined scope. This initiates task delegation within a sandboxed workflow governed by plan_confirm approvals.

Can I use custom agents for multi-agent coordination?▼

Yes, custom agent sessions support multi-agent coordination by allowing multiple spawned sub-agents to operate within scoped contracts. Each agent executes its delegated tasks in an isolated sandbox while adhering to the defined security level and plan_confirm workflow.

Does sandbox isolation enforce security levels for spawned sessions?▼

Sandbox isolation enforces security levels by applying scope checks and agent contracts to spawned sessions. This ensures consistent, secure execution that aligns with min_tier requirements, wizard_group specifications, and the designated security_level configuration.

What is the plan_confirm approval workflow for delegated tasks?▼

The plan_confirm approval workflow acts as a checkpoint for delegated tasks within a sandboxed execution environment. It requires validation before a sub-agent proceeds, ensuring that scoped contracts and security constraints are verified prior to action.
