What it does

Section titled “What it does”

Write a spec, break it into tickets, and Harmonic works through them. For each ticket it runs a coding agent to implement the change, has an AI critic review the result, and merges the branch and closes the ticket once it passes. You watch a board and step in only when a ticket needs a human.

Harmonic is designed to run alongside Matt Pocock’s Skills, which turn your spec into labelled tickets in your tracker. The ones labelled for an agent, Harmonic runs itself: it hands the agent the command the ticket calls for, /implement and the rest of the Skills, and lets them do the work exactly as if you’d typed it. If the agent stalls on a question it can’t answer, it hands the ticket back to you.

The rest of it

Section titled “The rest of it”
  • No lock-in. Harmonic drives every agent over ACP, so Claude Code, Codex, Copilot, and OpenCode are interchangeable.
  • Ad-hoc work too. You can queue a one-off task by hand instead of from the tracker. Those add a human review gate: you accept or reject before anything merges.
  • Glanceable. One board per repo, readable from a side monitor, with live token usage and cost on every attempt.
