All built-in agents
Agentastic ships with 33 built-in agent definitions and auto-discovers them when installed. Any terminal agent not listed here can still be added via Settings > Connections.Feature support matrix
Not all agents support the same capabilities. The table below shows which features are available per agent.Feature descriptions
Auto-Approve lets Agentastic skip permission prompts for file read/write operations. This is useful for hands-off workflows where you want the agent to run autonomously without pausing to ask for confirmation. Resume continues from a previous agent session. Agentastic can pick up exactly where the agent left off without losing context, so you don’t need to re-explain the task when restarting. Initial Prompt passes your instructions to the agent when it starts. Most agents support this, which allows Agentastic to send your prompt automatically from Agent Home when you launch a new session.Agent descriptions
