What it does when it runs

Find and validate phone numbers for a list's contacts (capability phone_enrich), advancing them to stage 'phone_enriched'. Runs the configured phone_enrich waterfall, validates each number (phone_validate), prefers mobile, and honors the pre-paid-enrichment gate. Use when the user wants to "find phone numbers", "enrich phones for list N", or run only the phone stage.

The skill

Source on GitHub ↗

Reproduced in full from kkrlstrm/gtm-pipeline/blob/3fdc07a14e4f3991eba66ec2e8a9feb8fec4a197/.claude/skills/phone-finder/SKILL.md, which is licensed APACHE-2.0 (repository). 80 words, 0 headings.

Input (list_id, optional input stage to read, optional max/skip): $ARGUMENTS

Execute the phone finder: read agents/phone-finder/agent.md and follow it exactly — bootstrap (config + resolve the phone_enrich and phone_validate waterfalls from keyed providers), load contacts via storage/cli.py query_by_stage, run the waterfall (script adapters or manifest-driven requests) applying each manifest's match_key_priority, validate found numbers, pick the best (mobile > direct > switchboard), honor the pre-paid gate, then advance_stage to phone_enriched (advancing not-found contacts too). Report the waterfall results and phone-type breakdown.
