Agentic tools
These tools extend the agent: load skills, delegate subtasks, connect MCP servers and generate media, while staying inside the same Action-or-Terminate loop.
params use_skill tool Loads the complete body of a catalog skill. spawn tool Delegates an isolated subtask to a subagent. browse tool Reads or interacts with URLs. generate_image tool Generates/transforms images in the workspace. mcp__<server>__<tool> dynamic Tools exposed by configured MCP servers.
spawn is for parallelism or specialization, not every small step. MCP tools enter the same registry and policy surface as native tools.
