Weekly local competitor intelligence brief in Slack

Build me a weekly local competitor intelligence brief that runs on a cron, every Monday at 8am in my local time zone, and posts a digest to a Slack channel I configure.

Inputs the workflow needs (expose these as configurable variables): the channel ID for the Slack channel to post in; a list of competitor entries (each entry is either a Google Maps business name plus city, or a Google Maps business_id / place_id); a separate entry for my own business in the same shape; and an optional region (ISO country code, default us) and language (ISO 639-1, default en).

Each Monday, for my business and every competitor, the agent should: (1) call Local Business Data's Business Details Plus to pull current rating, review_count, and the AI-derived keywords_mentioned_in_reviews; (2) call Business Reviews to fetch the most recent 5 to 10 reviews sorted newest first, respecting the cursor pagination if it needs to page; (3) call Business Posts to surface any new owner posts since the prior week, again respecting cursor pagination. Resolve any name-based entries to a business_id first by running a Local Business Data Search and picking the top match in the configured region; cache the resolved id in the run so we do not re-resolve every week.

Use the prior week's posted brief in the same Slack channel as the baseline for comparison. For each competitor, compute and write: rating delta versus last week (if available), review_count delta, two or three recurring complaint themes pulled from the keywords and review text, two or three new positive themes, any promotions or announcements from new owner posts, and a one-line read on whether they appear to be gaining or losing ground.

Then post one Slack message via the Slack Bot Send a Message action to the configured channel. Format with Slack mrkdwn (single-asterisk *bold*, underscores for italic). Structure: a header with the week-of date, a one-paragraph 'what changed this week' summary across the set, a bullet block per competitor (name, rating with delta, review_count with delta, top complaints, top praise, any new promotion), a section for my own business in the same shape, and a 'watch closely' callout at the bottom that names the one or two competitors whose movement most deserves attention this week and why.

Operational notes: respect Local Business Data's 5 requests per second per key limit and the cursor pagination contract on reviews and posts; treat a missing prior brief on the first run as 'no baseline yet' and just publish the snapshot. Keep the message under Slack's practical length (split into a threaded reply if it would exceed it) and make sure the channel id is the one and only place the channel is configured.
