Common edits
- Rename the copied play before the first run so it is owned by your workspace.
- Map your CSV headers into the expected input fields and add status or miss_reason columns.
- Keep stable step, fetch, dataset, and play-call ids so retries and durable receipts stay useful.
- Edit the final projection before scale so the output table matches your CRM or campaign import.
Use it when
- You need data from Leadmagic, Hunter, Datagma, Findymail, Icypeas, Prospeo, Deepline, Fullenrich, Lusha, Contactout and Dropleads in one pass.
- You want a repeatable pipeline instead of one-off lookups.
- You want an agent or teammate to run the same workflow on demand.

$ Use the deepline-gtm skill's plays recipe to turn the Deepline play "Work Email CSV from Names and Domains" (https://deepline.com/p/deepline/name-and-domain-to-email-waterfall-batch) into an editable scratchpad play. Inputs: csv. Outputs: email_result, email, email_source, email_validated, email_result.pattern_first_at, email_result.pattern_flast, email_result.pattern_first_dot_last, email_result.pattern_firstl, email_result.pattern_firstlast, email_result.hunter_email, email_result.leadmagic_email, email_result.datagma_email, email_result.findymail_email, email_result.icypeas_email, email_result.prospeo_verified_email, email_result.native_email, email_result.fullenrich_email, email_result.lusha_email, email_result.contactout_email, email_result.dropleads_email. The .play.ts file is the source of truth: copy the play, rename it for this user's workflow, encode input mapping/validation/status/output projection in the play, and iterate there instead of doing one-off CSV post-processing. Keep stable dataset names, dataset row keys, and step/fetch/play-call ids across edits. Provider tool calls reuse paid work by play, tool, semantic input, auth scope, provider action version, and cache policy unless you intentionally change those inputs or refresh stale data. # install Deepline if the CLI is missing npm install -g deepline@latest && npm exec --yes --package=deepline@latest -- deepline setup --json # inspect the live contract deepline plays describe prebuilt/name-and-domain-to-email-waterfall-batch --json # copy to an owned scratchpad, then rename the play inside the file before first run deepline plays get prebuilt/name-and-domain-to-email-waterfall-batch --source --out name-and-domain-to-email-waterfall-batch-scratchpad.play.ts # edit name-and-domain-to-email-waterfall-batch-scratchpad.play.ts: set an owned play name, add mappings/validation/status/miss_reason/final columns deepline plays check name-and-domain-to-email-waterfall-batch-scratchpad.play.ts # run the scratchpad on your data deepline plays run --file name-and-domain-to-email-waterfall-batch-scratchpad.play.ts --input '{"csv":"<your-file.csv>"}' --watch # only for an exact one-off with no edits or custom output deepline plays run prebuilt/name-and-domain-to-email-waterfall-batch --input '{"csv":"<your-file.csv>"}' --watch Play spec (JSON): https://deepline.com/api/v2/shared-plays/prebuilt-name-and-domain-to-email-waterfall-batch
