Cold Email Template Builder

Design a cold-outreach sequence and commit it to a fixed template set: the actual approved copy for every touch, with {{input_field}} placeholders and variant-routing rules. This skill does the thinking — explore angles, form pain hypotheses, decide the sequence arc, pick proof points — and bakes the result into final copy.

The template is rendered later by email-generation via plain deterministic substitution. There is no runtime LLM writing emails per row.

Architectural Principle

This skill is design-time. It commits to copy; it does not defer decisions to a runtime model.

Older versions of this skill emitted an LLM instruction prompt and let a per-row model write each email. That is retired. Per-row variance is now expressed two ways only: (1) {{input_fields}} filled upstream, (2) discrete variant templates selected by a routing key. Everything else is identical across the batch.
