Monday morning macro briefing for your team in Slack

Build me a weekly agent workflow that posts a global macro briefing to my team in Slack every Monday at 8am in my timezone.

Trigger: cron, Mondays 08:00 in the user's timezone.

Inputs the user configures at setup: (1) a list of ISO3 country codes to cover, defaulting to USA, GBR, DEU, IND, BRA, and (2) the Slack channel to post into.

What the agent should do on each run:

1. Use World Bank's Get Indicator Data to fetch the most recent value and the prior-year comparable for each configured country across these four indicators: NY.GDP.MKTP.KD.ZG (GDP growth, annual %), FP.CPI.TOTL.ZG (CPI inflation, annual %), SL.UEM.TOTL.ZS (unemployment, % of labor force), and NE.RSB.GNFS.ZS (trade balance, % of GDP). Batch the country codes per request and pass format=json. Use mrnev=1 (or equivalent) so null years are skipped and the result is the most recent non-empty value. Always read both halves of the World Bank response envelope (the metadata object and the data array).

2. For every country x indicator pair, compute the change versus the prior-year comparable and rank the largest moves. Flag accelerations and slowdowns: a country whose GDP growth is up sharply, an inflation print that swung materially, an unemployment rate that ticked up or down, a trade balance that tipped from surplus to deficit or vice versa.

3. Write a punchy 4 to 6 bullet briefing in Slack mrkdwn (so *bold* not **bold**). Open with a one-line headline that names the standout story of the week. Each bullet should cover one notable shift, name the country, give the new value and the prior-year value, and add a short why-it-matters line aimed at a global business operator (think Deloitte Weekly Global Economic Update or McKinsey Global Economics Intelligence, but shorter). For every country mentioned, include a Slack mrkdwn link back to https://data.worldbank.org/country/<ISO3> so readers can click through.

4. Post the briefing via Slack's Send a Message to the channel the user configured. Keep the message under ~1500 characters so it renders cleanly. No em dashes anywhere in the copy — use periods or commas. If World Bank returns no usable data for a country (all null), skip it and note the skipped country in a short footer rather than failing the run.

Tone: concise, business-grade, no hype, no hedging. The briefing should read like a single calm paragraph of bullets that a CFO or COO can skim in 30 seconds.
