Agent Skills are modular capability definitions that package domain-specific guidance, tools, and patterns for recurring agent tasks.

Subagents are narrowly scoped AI assistants that can be invoked by a primary agent to perform specific subtasks more efficiently.

Hooks are automation points tied to lifecycle events that let teams enforce checks, trigger scripts, or modify behavior around agent actions.

Slash Commands are user-invoked commands that start with a slash and execute predefined workflows, tools, or agent behaviors.

Approval Modes are policy settings that control which operations an agent can run automatically and which require explicit human approval.

Non-interactive Mode executes agent workflows in a command-driven context without live chat interactions, useful for automation and pipelines.
