What its author says it does

Copied from the file, not written here

Build Meta custom audiences from CSV files (CRM leads, email/phone lists, WhatsApp contacts). Hashes PII client-side (SHA-256, normalized per Meta spec) before upload. Triggers on prompts about uploading leads/contacts/lists as custom audiences on Meta.

Meta Ads — Audience Builder

When to use

"Sobe essa lista CSV como custom audience no Meta"
"Cria uma audiência dos leads do CRM na conta acme"
"Upload these WhatsApp contacts as a Meta custom audience"
"Bulk hash and upload emails to audience 'Hot Leads Abril'"

Input

CSV file with columns matching one or more of: email, phone/telefone/celular/whatsapp, first_name/nome, last_name/sobrenome
Audience name (required)
Account ref from config/accounts.json
Optional: description

Execution

adskills meta audience \
  --account acme \
  --csv ./leads/abril-hot.csv \
  --name "Hot Leads — Abril 2026" \
  --description "Top-tier leads from CRM exported 2026-04-24"

PII handling

Emails lowercased + trimmed before SHA-256
Phones normalized to E.164 (Brazilian: strips non-digits, prefixes 55 if missing)
Names lowercased + trimmed
Only the hash leaves the machine — raw PII never sent to Meta
CSV file is not copied or cached — read once, hashed, discarded

Batching

Default 5000 rows per API call (Meta limit is 10k, keep margin for invalid)
Each batch report shows num_received and num_invalid_entries from Meta
Failed batches do not abort the run — partial success is reported

Guardrails

Dry-run flag (--dry-run) simulates without creating audience or uploading
Creates audience with customer_file_source=USER_PROVIDED_ONLY (required by Meta TOS for CRM data)
Refuse if CSV has no recognizable PII columns — print supported headers
