What a Framework Gives You: Build or Adopt

When a team installs an agent framework, what does it receive, and what does it give up?

Unlike asking which framework is best, this question has an answer that survives new releases. Every agent framework packages some mix of the same five things. Each saves a different amount of work, and each moves a different decision out of your code and into the framework. Once you can separate them, you can adopt the ones that are expensive to write and write the cheap ones yourself.
