Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

google-maps-list-builder scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Google Maps List Builder

A self-contained tool for scraping business listings from Google Maps. Give it a search query (e.g., "pizza restaurant") and a location (zip code, city, or coordinates), and it returns structured data for every matching business — written to CSV.

How this fits in the cold email flow

Google Maps gives you COMPANIES (name, domain, phone, address, ratings). It does NOT give you PEOPLE. To run cold email:

  1. Run this skill → CSV of businesses with company_domain
  2. Run /icp-prompt-builder on a sample of 50 — tune a qualification prompt to filter out bad fits before paying for downstream enrichment
  3. Run /blitz-list-builder with the filtered CSV → adds owners/managers to each business
  4. Run /email-waterfall → fills in missing emails
  5. Run /cold-email-starter-kit's smartlead-add-leads.ts → upload to Smartlead

This skill is only the first step.

Required step: Qualify with /icp-prompt-builder

This is a required step. Do not skip it.

Google Maps will happily return 10,000 "pizza restaurants in Illinois," but most of those won't match your actual ICP (maybe you only want 50-200 seat operators, or only ones without online ordering). Before spending on enrichment, sample ~50 results and run /icp-prompt-builder:

  1. Evaluate 10 results with an AI qualification prompt
  2. You flag "this one should be NO, they're a chain franchise"
  3. Refine, run next 10
  4. Stop when 2 rounds show no corrections
  5. Apply tuned prompt to filter the rest of the scrape

Why required: downstream owner-finding (via /blitz-list-builder) and email waterfall cost $0.10-$0.30 per contact. On a 10,000-business scrape, that's $1K-$3K. Qualifying upfront saves 50-80% of that spend on average.

What You Need Before Starting

  1. Node.js 18+ and npm installed
  2. A RapidAPI account (free tier available) with a subscription to the Maps Data API:
