> A Claude Code session that builds a 50-prospect list with verified work emails.



There are many guides on prompting Claude Code to be a sales assistant. This is not one of them. This is a real workflow, tool calls included, that ends with a sheet of 50 Heads of Engineering at U.S. robotics companies, enriched with work emails, on a weekly refresh schedule.

The setup is one command. Claude Code connects to [pipe0](https://pipe0.com)'s MCP server. By connecting to pipe0 Claude Code receives 100+ enrichment tools.

```bash title="Connect"
claude mcp add --transport http pipe0 https://api.pipe0.com/v1/mcp
```

Claude Code opens the OAuth sign-in on first use. Follow the instructions.

## The prompt [#the-prompt]

```text title="The whole instruction"
Let's find 50 Head of Engineering prospects of robotics companies in the U.S. Store the results in a pipe0 sheet.
```

That is the entire input.

## What the agent actually does [#what-the-agent-actually-does]

From here, Claude Code uses pipe0 to build a workflow. The sequence of tools is roughly this:

```text title="Tool sequence"
list_searches     -> picks a prospecting source for people
get_search_schema -> fetches the exact filter shape for the search
create_sheet      -> "us-robotics-engineering"
validate_effects  -> the chain checks out against the sheet schema
run_effects       -> [search:run, pipe:add (work email waterfall), rows:enrich]
verify_outcome    -> reads the real cell statuses when the run finishes
```

## The result is a sheet, not a wall of JSON [#the-result-is-a-sheet-not-a-wall-of-json]

The output lands in a [sheet](/docs/sheets). Sheets are a UI you can use to visualise your results. You can use your agent to read from and write to a sheet.

If you prefer to receive your data as JSON or CSV and don't want a sheet to be created you can simply omit the sheet creation from your prompt.

## Qualify and schedule [#qualify-and-schedule]

Two follow-up prompts finish the job:

```text title="Narrow the list"
Drop everyone without a work email.
```

```text title="Keep it fresh"
Refresh this search every Monday at 8am Berlin time and email me a report of new prospects.
```

The first runs a filter effect. The second becomes a cron schedule plus a versioned, emailed report. The schedule runs without the agent, and because a run only recomputes stale cells, a week with no new prospects costs nothing.
