Reference: Outbound SDR Research + Drafting Agent

Architectural notes

Reference architecture for an outbound SDR agent: researches a prospect,
drafts a personalized email, logs activity to CRM.

Why these picks:
- Gemini for the research subagent because of long context (consume many
  pages of prospect content at once).
- Stagehand for browser-based prospect research where the public web
  isn't available via API.
- Zep's temporal knowledge graph for tracking how prospect signals
  evolve over time.
- Fly.io because the agent runs long sessions that don't fit serverless
  timeouts cleanly.

Common gotchas:
- LinkedIn anti-bot defeats most naive scraping; budget for failures.
- Personalization quality drops fast if research input is shallow.
