Autonomous AI agents
that work a real backlog.
Delegate features, not prompts — across 7 editors.
Harness turns your AI assistant from a one-shot code generator into an autonomous engineer. It reads a declarative feature backlog, picks the next task, writes the spec, implements it, and moves the feature through an auditable state machine — using the same contract whether your team is on Claude Code, Cursor or Aider.
The problem Harness solves
Prompting an AI file by file does not scale. Context is lost between prompts, work is invisible to the rest of the team, and there is no record of what the agent did or why. Harness replaces ad-hoc prompting with a structured backlog and a state machine — so AI work becomes trackable, reviewable engineering.
What Harness does
Declarative feature backlog
A feature_list.json the AI reads to pick the next item and update as it works. Context survives between sessions — no re-briefing every prompt.
One contract, 7 editors
A universal AGENTS.md plus per-editor configs for Claude Code, Cursor, Windsurf, Continue, GitHub Copilot, Aider and Codex CLI.
Spec-author + spec-reviewer
Dedicated subagents draft EARS specifications and review them against an approval gate before a single line of code is written.
CI-enforced invariants
One command wires a GitHub Actions workflow that validates harness state and spec quality on every push — the backlog can never drift.
