A single-subreddit Claude agent that reads EVERY new post in r/YourNiche, scores it on a DM-worthiness rubric (intent weighted 2x, threshold 24), and emails 1-3 a day worth a personal DM — with the rubric, the workflow, the etiquette rules that keep your account from being shadowbanned, and a case study: an SEO consultant ran this 90 days, sent 180 DMs at a 38% reply rate, closed 6 engagements at $4k-$12k for $46k of pipeline on a $14/month stack.
An n8n + Claude Haiku 4.5 agent that watches 9 subreddits, scores every post on a 3-axis rubric (intent, urgency, fit), and posts a top-5 daily digest to Slack — with the verbatim Claude prompt, the 9-sub shortlist, the cost math, and the week-2 finding that pruned it down to 4 subs for a +120% signal lift.
A real look at AI-assisted Reddit engagement: the four tells that get comments flagged, the draft-edit-verify workflow that survives mods, the monitoring stack I actually use, and the line between value-add and spam that everyone glosses over.
