Build a Chorus coaching playlist in minutes, not an afternoon

**Objective:** Build a coaching playlist called `{playlist-name}` from conversations about `{topic}` in the last `{lookback-days}` days (default 60), by clipping a moment out of each one.

**Step 1: Find or create the playlist**

Call `chorus-get-playlists` with `name.contains` set to `{playlist-name}`. If exactly one matches, use its `playlist-id`. If several match, list them with owner and size and stop, asking which. If none match, call `chorus-create-playlist` with `name` set to `{playlist-name}` and a short description saying what the playlist collects, then call `chorus-get-playlists` again with `name` set to the exact name to read back the new `playlist-id`. You need that numeric id and no other tool will give it to you.

**Step 2: Find the candidate conversations**

Call `chorus-get-engagements` with `subject.contains` set to `{topic}` and `date.from` set to the start of the window. Keep the `conversation-id`, `subject`, `date`, `duration`, `user-name` and `meeting-summary` of each.

**Step 3: Choose the clips**

Pick at most five conversations. Prefer ones whose `meeting-summary` shows the topic actually being handled rather than merely mentioned, and spread them across different `user-name` values so the playlist is not one person. For each chosen conversation decide a start offset in seconds and a length in seconds, using the summary to place it; keep clips between 30 and 120 seconds. If a summary gives you no basis for an offset, say so and use the conversation's midpoint, flagged as approximate.

**Step 4: Confirm before writing**

List the proposed clips as a table: conversation subject, date, owner, start offset, length, and the description you will attach. Ask for approval and stop. Do not write anything until the answer comes back.

**Step 5: Add the moments**

Only after approval, call `chorus-add-playlist-moment` once per approved clip, with `playlist` set to the playlist id from step 1, `call-id` set to that conversation's `conversation-id`, `moment-time` set to the start offset in seconds, `moment-duration` set to the length in seconds, and `description` set to one sentence saying what the clip demonstrates. One call per clip, no retries on a call that already succeeded.

**Step 6: Report**

Say which playlist was used or created, list each clip that was added, and list any that failed with the error.

**Rules & Guidelines:**

* Writing tools allowed here are `chorus-create-playlist` and `chorus-add-playlist-moment`, and only as described. Do not call `chorus-update-playlist`, `chorus-update-playlist-moment`, `chorus-update-moment`, `chorus-add-moment`, `chorus-export-recordings` or `chorus-export-scorecards`.
* Never guess a playlist id. It comes from `chorus-get-playlists` or from reading back a playlist you just created.
* Offsets and durations are in seconds, not minutes. Say the values back in the confirmation table so a mistake is visible before it is written.

**Validation:**

* If no conversations match `{topic}`, report that and stop without creating a playlist.
* If the playlist was created but no clips are approved, say the playlist exists and is empty.
* If a moment fails to add, report the failure and do not retry blindly.
