I'm Launching an AI Agent Toolkit on Product Hunt in 72 Hours — Here's Everything I Built

I've been building in public for the past 6 weeks. On Monday (April 21), whoffagents.com goes live on Product Hunt.

Here's a full breakdown of what I built, what broke, and what I'd do differently.

What Is whoffagents.com?

A curated toolkit of production-ready Claude agent skills — pre-built, tested workflows you can drop into your Claude Code setup in under 5 minutes.

Think of it like npm for agent behaviors. Instead of spending 3 days engineering the perfect "research + summarize + post" pipeline, you install a skill and start from a working baseline.

The Stack

  • Claude Code — primary execution environment
  • Anthropic SDK — claude-sonnet-4-6 and claude-haiku-4-5 for cost tiering
  • n8n — workflow orchestration between agents
  • Stripe — payments (first sale landed today — $49)
  • dev.to + YouTube + LinkedIn — distribution

All of it runs autonomously. I'm not touching a keyboard for most of what ships.

What Actually Runs Autonomously Today

  1. Content pipeline — research → draft → publish to dev.to (you're reading one right now)
  2. Sleep audio factory — generates 1-hour ambient tracks, encodes to 1080p video, uploads to YouTube
  3. YouTube Shorts — script → TTS voiceover → Pillow frames → ffmpeg → upload (8 shipped today)
  4. Heartbeat monitoring — 8 health dimensions, SIGTERM alerts, disk/memory checks every 5 minutes
  5. Email triage — reads 5 inboxes, flags billing/security/platform alerts

The whole system runs on launchd (macOS), with 27 active plists firing on schedule.

The Ugly Parts

What broke:

  • YouTube upload path bug (concatenated relative + absolute path, crashed silently)
  • dev.to bot detection on bulk publish (fixed: randomized delays + user-agent rotation)
  • Prompt cache TTL silently dropped from 1hr to 5min — cost me ~40% on API spend until I caught it
  • Sleep video Remotion render estimated 50 min, actually ran 90 min

What I'd do differently:

  • Build the monitoring layer first, not last
  • Set rate limits per platform before you hit them (not after a 403)
  • One agent per domain, not one agent trying to do everything

The Numbers

Metric Value
Articles published (today) 24
YouTube Shorts (today) 8
Sleep videos (today) 4
Stripe revenue (today) $49
Agents running 5 (Atlas, Prometheus, Athena, Apollo, Hermes)
Launchd plists 27

What Happens on Launch Day

  • Product Hunt listing goes live April 21
  • First 50 upvoters get the full skill library free
  • Paid tier: $47/mo (solo dev) or $97/mo (team)
