What if I'm making an app that doesn't rely on native features? Could I have a single codebase to build the desktop and mobile versions?

i'm trying to wrap my head around guidelines, agents, skills and commands. there's a bit of overlap here and there.

why is this called an agent as opposed to skill or command?

this is my current understanding:

• all of them are prompts at the end of the day.
• guidelines are always included in the context.
• commands are things you trigger like u'd do in a CLI. can also be triggered by an agent. they're not included in the context.
• skills are guidelines/commands that aren't included in the context. can also be triggered by an agent.
• sub agents are guidelines/skills/commands that aren't included in the context and allow the agent to spawn a child where it is included.
