Weekly competitor tech stack intelligence email

Build me an agent workflow that runs every Monday at 7am in my timezone and emails me a weekly technographic intelligence digest about a watchlist of companies.

The workflow should expose this configuration: a watchlist of domains (competitors, partners, and key prospects), a small list of technology categories I care about (for example CDP, analytics, payments), a list of recipient email addresses, a 'skip noise' filter so I can drop low-signal change types like CDN, ad pixel, and font swaps, and a tone setting that flips between analyst-formal and casual.

On each run, the trigger is a cron schedule for every Monday at 7am.

First, for each domain in the watchlist, call BuiltWith's Change API to get technology additions and removals over the past 7 days. Keep the AI-generated business-context blurbs that come back with each change, because that is the narrative the email is built on.

Second, for each technology category I configured, call BuiltWith's Trends API to pull adoption movement across the BuiltWith index. Identify which technologies in each category are gaining or losing share the fastest over the past week.

Third, apply the 'skip noise' filter so low-signal changes are dropped before the agent writes anything.

Fourth, synthesize everything into a single email body with three sections. Start with a one-paragraph executive summary that names the most interesting move of the week. Then a 'Moves on my watchlist' section grouped by company, listing the changes that matter and why they matter, using the BuiltWith business-context blurbs to explain the so-what. Then a 'Category momentum' section that highlights the technologies gaining or losing share fastest in my chosen categories. If a domain on the watchlist had no changes that week, mention it briefly under a 'Quiet this week' line so I know it was checked.

Fifth, pick a subject line that surfaces the single most interesting headline of the week, something like 'Acme dropped Segment for RudderStack' or 'Stripe gaining ground in fintech'.

Finally, send the email via Gmail's Send a Message action to my recipient list. Match the tone setting (analyst-formal vs casual) on every prose section, including the subject line.
