A Marketplace deal radar: let Muse watch prices instead of refreshing listings

Business model

Author @JeremiahEnglan5 shares a Meta Muse workflow: the always-on agent scans FB Marketplace daily, records past items, and alerts when a good deal reappears — a complete short-form X post.

No paying customer or resale profit is demonstrated. Deal discovery may save time; resale demand still needs testing.

Workflow

  1. Specify product criteria and a price ceiling.
  2. Record candidate listings with their source links.
  3. Compare candidates against explicit criteria and prior records.
  4. Prepare an alert; do not purchase automatically.

Adaptation plan

Search access, refresh frequency, price accuracy and actual resale outcomes are unknown.

Starter prompt

Written by AgentFlow; not the original author’s prompt. Not independently deployed in Muse or Grok.

Compare only the supplied Marketplace listings against my criteria. Return source link, price, condition, match reason and uncertainty. Flag duplicates and missing details. Do not invent live availability, contact sellers or buy anything.

Running costs and pitfalls

Search access, refresh frequency, price accuracy and actual resale outcomes are unknown. No independent cost benchmark is available. Check subscriptions, permissions and external actions before running a workflow.

Author-reported results are not independently audited.

The breakdown and starter prompt are AgentFlow’s analysis and adaptation; results are not guaranteed.
