See what is happening in a repository this week

**Objective:** Summarize the last `{lookback-days}` days (default 14) of activity in repository `{repository-name}`.

**Step 1: Resolve the repository**

Call `azure-devops-get-repository` with name `{repository-name}`. If several projects have one, list them and stop. Note id and default-branch.

**Step 2: Read activity**

Call `azure-devops-get-commit` with repository-id and author-date.from set to the start of the window, `azure-devops-get-push` with repository-id and date.from, and `azure-devops-get-pull-request` with repository-name `{repository-name}`. Count commits per author and per day, and total additions and deletions.

**Step 3: Check branches**

Call `azure-devops-get-branch-stat` with repository-id and list branches that are far ahead (ahead-count above 20) or far behind (behind-count above 50) of the default branch.

**Step 4: Report**

Contributors ranked by commits, busiest days, pull requests opened and completed in the window, notable large commits, and diverged branches.

**Rules & Guidelines:**

* This prompt is read-only. Call only the `azure-devops-get-*` read tools named above; never create, update, comment on, approve, queue, abort or delete anything in Azure DevOps.
* The tools only return data the connected account can see; never infer data from projects outside that access.
* Do not rank people as a performance judgement; present activity only.

**Validation:**

* If there are no commits in the window, say so and report the date of the most recent one.
