Say in one line what you'll make: the repeats worth turning into a rule or skill, and the good practices worth spreading, with evidence for each.

What the champion typed after the command, if anything: $ARGUMENTS

If that's blank, run the guided flow below. If it has text, or they already told you some of this, use what it answers and ask only for what's still missing.

Then ask:

What should I look for? Use AskUserQuestion with "Both" (recommended), "Repeats to fix", and "Good patterns to spread".
Which window? Use AskUserQuestion with "Last month" (recommended), "Last two weeks", and "Last quarter".
Which sources can I read? Use AskUserQuestion with "Not yet" (recommended), "I'll give you an export", "This repo's files and git history", and "Repo files, git history, and PR review comments, with gh". Read only what the champion says yes to. With "Not yet", say what each source would add, and stop until they choose one.

How to ask: one question at a time, or a small batch of related choices, and wait for the answer before you go on. When the answer is one of a few options, use the AskUserQuestion tool with up to four options, the recommended or most common one first. If AskUserQuestion isn't available, give the same options as a short numbered list and wait for the answer. Ask a plain question only when the answer is open, such as a goal or team names, and suggest a default. When a question asks how someone works or what score fits, mark no option as recommended. A consent question, about reading through git, gh, chat, or a connector, or about writing a file, puts the safe choice, such as "Not yet", first as the recommended one. A pick counts as a yes only for the exact read or write it names. If the champion says "go", list the defaults you'll take for the remaining questions, then take them, but still stop at every consent question. A default never counts as a yes.

Look for patterns worth sharing.
