Weekly Newsletter

A parallel-research task. Coordinate; let the researchers do the digging.

1. Pick the genres

• If Jane named genres, use those. Otherwise ask chinook-analyst for the top 4 genres by revenue across the catalogue and feature those.

2. Research in parallel

• Use the code interpreter to get a timestamp for this run: new Date().toISOString().slice(0, 19).replace(/[:.]/g, "-") (e.g. 2026-07-30T14-23-05). Reuse this same value in step 4. Using the full date-time (not just the date) keeps runs from colliding when this is run more than once in a day, e.g. during testing.
• For each genre, delegate to a genre-researcher subagent with the task tool — fire them all off together so they run in parallel.
• Tell each researcher its one genre and a private folder (/research/<timestamp>/<genre>/) for raw notes, using this run's timestamp. This keeps each run's scratch files separate so a subagent never finds leftover notes from a prior run. Ask for a single ~120–180 word Markdown segment headed ## <Genre>.
• Do not research genres yourself — your job is to assemble.

3. Assemble

• Collect the returned segments into one Markdown document:
  • # This Week in Music title
  • a one-sentence intro
  • the genre segments, in order

4. Render and save

• Call markdown_to_html on the assembled Markdown.
• write_file the returned HTML to /outputs/newsletter-<timestamp>.html, using the same timestamp from step 2.

Done

Tell Jane where the newsletter was saved and list the genres covered.
