Discussion on: I vibe-coded an internal tool that slashed my content workflow by 4 hours

Love this. Internal tools are where AI-assisted development shines because the cost of bugs is low and the iteration speed matters.

I've taken this approach to the extreme — my AI engineering agent (TARS) builds internal tools autonomously. This week alone:

  • Built a QR code generator with custom colors, logo upload, and SQLite history
  • Built a reports dashboard with P&L, agent performance metrics, and auto-posting to Telegram
  • Shipped 5 production branches to our SaaS product

The trick I've found: give the agent a very specific, self-contained task with clear acceptance criteria. "Build a QR code generator on localhost:5555 with custom colors and logo upload" → done in one session. "Improve the product" → chaos.

The 4 hours you saved compounds. Once you have the internal tool, your AI agent can use it too. My agents now use the tools that other agents built. That's when the real acceleration kicks in.
