Weekly creator discovery digest in Slack

Every Monday at 9am US Eastern time, run a creator discovery digest for our marketing team and post it to a Slack channel. The trigger is a cron schedule pinned to Mondays at 09:00 America/New_York.

Take a configurable list of topics or product categories we care about, for example: skincare, fitness gear, gaming peripherals. The topic list, the destination Slack channel ID, and the platforms we want covered (default: YouTube, TikTok, Instagram) are all set up as workflow inputs so they can be edited without rewriting the agent.

For each topic, use Tubular Labs (Execute GraphQL Query) to find the top 5 to 10 creators on each selected platform whose videos performed best in that topic over the past 7 days. Tubular's GraphQL schema is rooted at viewer, so build small, explicit queries that traverse the creator and video connections under viewer. The interactive editor at developer.tubular.io is the source of truth for available fields. If something is unclear, start by running Introspect Schema once to discover the right fields, then write tight queries that only ask for what the digest needs (do not over-fetch, Tubular meters by data volume).

For each creator, pull the headline stats marketers actually use: total views in the last 30 days, follower or subscriber count, engagement rate, two or three top recent videos with view counts, and primary audience demographics (top countries, age band, gender split). Capture the creator's platform URL so we can link to their channel from Slack.

Take an input list of creators we already work with (handles or display names) and drop any matches before writing the digest, so the message stays fresh week over week. Treat it as a simple case-insensitive deny-list against creator handles and display names.

Write the digest as one scannable Slack message, grouped by topic, with each creator on a single line that includes their name (linked to their profile), the platform, one headline stat, and a one-line why they matter that calls out the most interesting fact (breakout velocity, audience demo fit, sponsor-friendly category mix, recent viral video). Use Slack mrkdwn formatting: *bold* for topic headers, <url|text> for links. Keep the whole message under one screen if possible by capping at 5 creators per topic when more than three topics are configured.

Post the final digest to the configured Slack channel using Slack Bot (Send a Message).

If a topic returns no eligible creators after exclusions, still include that topic in the digest with a short note so the team knows the workflow ran cleanly. If Tubular returns a rate-limit or quota error, back off and surface the error in the Slack message instead of failing silently.
