You’ll finish with: a decision record that names the simplest useful capability.

The names overlap, which is not especially helpful when you just want a weekly summary. Choose the missing capability first: instructions, access, a repeatable sequence or independent task execution.

Set up

Allow 15 minutes. Use the sample and inspect what your existing app supports. A new plugin is not automatically required.

FICTIONAL PRACTICE MATERIAL
Need: read one project note and draft a weekly summary in a fixed format. Available: notes can be pasted manually; the format has five headings; sharing must wait for Jo.

Do the task

Separate the source-access problem from the writing-method problem.
Choose the smallest working combination, starting with pasted notes and a saved prompt.
Add a connection only if fetching notes repeatedly is the part worth improving.

Your reusable prompt

Compare a saved prompt, a skill, a connector, a workflow and an agent for this task. Explain what each adds, what it does not add and the simplest first test.

PRACTICE INPUT
Need: read one project note and draft a weekly summary in a fixed format. Available: notes can be pasted manually; the format has five headings; sharing must wait for Jo.

Refine your result

Explain where a plugin fits as a package of capabilities and where MCP fits as a connection standard. Avoid treating either as a guarantee of safe access.

Check the result

A skill packages a method; a connector supplies access; a workflow orders steps; an agent can choose actions within its tools. Product definitions vary, so check the host app before installing.

Save and reuse

Save a brief capability decision. Test one missing piece at a time instead of installing a whole toolkit.

The practice input and teaching prompt are original 5HO material. Examples are fictional; they are not screenshots or claims of a completed real-world task.
Official documentation supports the relevant product concepts. Setup availability depends on your account; where a guide offers a fallback, it does not prove the connected capability worked.
