Weekly competitor influencer collab digest in Slack

Every Monday at 9am in the workspace timezone, build a competitor influencer-collaboration digest with Modash and post it to Slack so the marketing team can see which creators their competitors tapped last week.

Trigger: cron, weekly, Mondays at 9am.

Inputs to configure at setup:

- A list of competitor brand handles to track (Instagram, TikTok, or YouTube handles, or full profile URLs).

- The Slack channel to post the digest into. Use the Slack Bot integration so the message is posted by the workspace bot, not a specific user.

For each competitor handle in the configured list, the agent should:

1. Call Modash 'List Collaboration Posts' scoped to the past 7 days to pull every new sponsored or branded post that featured the brand.

2. Call Modash 'Get Collaboration Summary' for the same brand to fetch aggregated engagement metrics (averages, per-partner breakdowns). Use this as the baseline for what 'normal' engagement looks like for that competitor.

Then the agent should:

- Group new posts by creator, so a creator who posted multiple times for the same brand is listed once with their posts nested under them.

- Flag any post whose like or view count is above the brand's own recent baseline (use the summary endpoint's averages as the comparison).

- Flag any creator who appears across two or more competitors in the same week, since cross-brand creators are the most actionable signal.

- Skip any competitor with zero new collabs in the past 7 days. Do not pad the digest with empty sections.

Final output: a single Slack message sent via the Slack Bot 'Send a Message' action into the configured channel. Structure it as:

- A 3-bullet 'what changed this week' summary at the top. Cover the biggest engagement win, any creator who appeared across multiple competitors, and any obvious format or platform shift.

- One section per competitor that had new collabs, formatted with the brand handle as a header. For each creator under that brand, list: creator handle, content format (Reel, Story, Post, Short, or Video), headline like or view count, and a direct link to the post. Add a small callout like 'above baseline' next to standout posts and 'also tapped by @brandX' next to cross-competitor creators.

Formatting rules: use Slack mrkdwn (*bold*, _italic_, <url|text> for links), keep bullets short, no em dashes anywhere in the message. If the digest gets long, post the top summary as the parent message and thread the per-competitor sections as replies rather than sending one wall of text.
