​
Workflow Synths · Automations Lab

Automations should feel like a band, not a mess of scripts. Here’s the productivity set list.

​
1. n8n Masterclass

  • Stack: Self-hosted on Fly.io + Postgres backend.
  • Blueprints:
    • Daily Ops: pulls calendar, weather, and sends ritual digest.
    • Family Logistics: syncs school updates → shared Notion board.
    • Agent Guardrails: evaluates AI agent outputs before publishing.
  • Guides: Loom walkthrough + exported .json flows included in repo.

​
2. OpenAI Agent Pipelines

  • Architecture: Vercel edge function → OpenAI/Anthropic → Supabase vector store.
  • Use cases: Thinki.sh prompt coach, MetaLabs changelog writer, PTE practice grader.
  • Eval Harness: LangSmith, Truelens, and custom dataset to track hallucinations.

​
3. Bonus Flows

  • Zapier + Replit Agents: Quick experiments hooking Airtable → Slack → agent follow-ups.
  • Make.com for Creators: Auto-generate Instagram reels metadata + publish to Notion.
  • Airplane.dev Runbooks: Ops automations for deployments, cost sweeps, access requests.

​
4. Governance

  • Automations repo (/automation) with versioned flows + tests.
  • Secrets managed via Doppler.
  • Every workflow has an owner, SLO, and “pull-the-plug” switch.
Fork any of these flows, or request the private repo for deeper dives.
