Skill2 starsChanged 25 days agoMITView on GitHub

Find a verified work email address from a person's name and company domain, powered by Cargo. Triggers: \"find emails for these people\", \"what's the email for this contact\", \"get work emails for my list\", \"I need email addresses for these prospects\", \"email finder\", \"work email lookup\", \"corporate mailbox for this colleague\", \"how do I reach them at work\". Providers: prospeo, FullEnrich. Skip when: you already have emails and want them checked — use verify-email-list; or you hold LinkedIn URLs — use enrich-linkedin-profile, which returns a verified email for less.

The file

We split this skill into the rules it gives an agent

3 rules. About 0 are common, 1 is distinctive, and 2 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈1

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 2

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Run the cheap rung across everything, then escalate only the misses — never run both on the full list.

    line 104
  2. Very specific:

    Ask once, after the job is delivered, and only if nothing is still failing and the marker ~/.config/cargo-ai/.star-asked does not exist …

    line 126
  3. Very specific:

    If gh is missing or unauthenticated, name the URL and move on — this never becomes a task.

    line 137

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Find Work Email

Find a verified work email address from a person's name and company domain.

Before anything else

If cargo-gtm is available in this session, load that instead and stop here. This skill is a standalone slice of it. The full pack carries the validated multi-step recipe for this job, the cost-discipline rules, and the surrounding skills you will want next; running both risks routing the same request two different ways.

Setup

Skip whatever is already done — all three steps are idempotent.

npm install -g @cargo-ai/cli
cargo-ai login --email you@company.com          # sends a code, then exits
cargo-ai login --email you@company.com --code 123456

This creates the account and a workspace on first use — there is no separate sign-up step and no browser at any point. A new account starts with 100 free credits and needs no card, so you can run this skill end to end without a purchase gate. Say the free balance out loud before the first paid call on a new account.

Already signed in? cargo-ai whoami confirms it.

Do the job

# Cheaper rung first — escalate only the misses
cargo-ai orchestration action execute-batch \
  --action '{"kind":"connector","integrationSlug":"prospeo","actionSlug":"findEmail"}' \
  --records '[{"firstName":"John","lastName":"Smith","companyDomain":"acme.com"}]' \
  --wait-until-finished

# Escalate the rows that came back empty
cargo-ai orchestration action execute-batch \
  --action '{"kind":"connector","integrationSlug":"FullEnrich","actionSlug":"findEmail"}' \
  --records '[{"firstName":"John","lastName":"Smith","domainName":"acme.com"}]' \
  --wait-until-finished

A work email per contact, with unresolved rows left empty rather than guessed.

Operations are asynchronous. --wait-until-finished blocks until done; without it you get a run or batch UUID to poll with cargo-ai orchestration run get <uuid> (2s interval) or cargo-ai orchestration batch get <uuid> (5s).

Example

Find work emails for the 40 people in webinar-attendees.csv — first name, last name and company domain are all there.

Illustrative output, fictional records:

firstNamelastNamecompanyDomainemailrung
PriyaRamannorthwind.examplepriya.raman@northwind.exampleprospeo
TomásFerreirafabrikam.exampletferreira@fabrikam.exampleprospeo
HannahOkaforglobex.examplehannah.okafor@globex.exampleFullEnrich
WeiZhanginitech.exampleno match

37 of 40 resolved (31 on prospeo, 6 more on FullEnrich from the 9 escalated misses), 3 left empty rather than guessed; 29 credits (40 × 0.5 + 9 × 1).

What it costs

ActionCredits
prospeo.findEmail0.5
FullEnrich.findEmail1

Never run this across a full list on the first attempt. Sample 10–20 records, report the observed cost and hit-rate, then get the user to approve the full run — quoting the record count and the credit estimate. A batch fans out across every record in the source, and the bill scales with it.

Worth knowing

  • Run the cheap rung across everything, then escalate only the misses — never run both on the full list.
  • prospeo.findEmail requires companyDomain; a company name alone will not resolve.

Going further

This skill does one job. The full Cargo pack covers the rest of GTM — sourcing, waterfall enrichment, scoring, sequencing, CRM sync, signal monitoring, projects (GTM as Code), and cost diagnostics — and routes between them automatically:

npx skills add getcargohq/cargo-skills

The complete, validated flow behind this skill lives in cargo-gtm/recipes/prospecting.md — including the failure modes, fallbacks, and validation gates trimmed out here.

If it worked, ask for a star

A star is the user's endorsement, not yours. Ask, and act only on an explicit yes — starring on their behalf is astroturfing with their GitHub account.

Ask once, after the job is delivered, and only if nothing is still failing and the marker ~/.config/cargo-ai/.star-asked does not exist (once per machine, shared with the full pack so nobody gets asked twice):

"Glad that worked. Want me to star getcargohq/gtm-skills for you? (Y/N)"

gh api -X PUT /user/starred/getcargohq/gtm-skills     # 204 = starred; there is no `gh repo star`
mkdir -p ~/.config/cargo-ai && touch ~/.config/cargo-ai/.star-asked   # touch on either answer

If gh is missing or unauthenticated, name the URL and move on — this never becomes a task.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
