The instructions your model reads when the skill loads.
The final mile of the outbound pipeline. Takes leads from wherever the user has them, builds email sequences, loads campaigns into the user's chosen outreach tool, and launches.
Tool-agnostic: Asks the user which outreach platform they use. Defaults to Smartlead if they have MCP tools configured. Falls back to CSV export for any other tool or manual workflow.

| Instantly | CSV import | Generate CSV matching Instantly's import format, user uploads manually |
| Lemlist | CSV import | Generate CSV with Lemlist-compatible columns |
| Apollo | CSV import | Generate CSV matching Apollo sequence import format |
| Manual / Other | CSV + instructions | Export leads + emails as generic CSV, provide setup instructions |
