Writing Workflow
1. Select Platform & Format

Single Post Pattern
[Hook - stop the scroll]
[Context or specific detail]
[Insight or learning]
[Optional: engagement question]
Example:
Shipped curation v1 for agents.foo today.
Discovery is way harder than app stores. Agents are conversations, not static features.
Had to rebuild around context matching instead of keyword search.
Thread Pattern
1/N [Bold hook - main insight] 👇
2/N [Context or setup]
3-N/N [Key points, one per tweet]
N/N [Summary + CTA]
Rules:
- First tweet MUST end with 👇 or 🧵 to signal thread
- Use N/M numbering (1/7, 2/7... 7/7)
- Each tweet must stand alone
- Max 5-7 tweets (longer = blog post)
