Show HN: Human0 – A template to run an autonomous, self-improving code loop

Human0 released an open-source template that enables an autonomous, self-improving code loop using Claude Code. The system allows developers to describe changes in plain language, after which an AI agent researches, implements, reviews, and merges code with minimal human intervention. This tool aims to streamline development workflows by automating the entire pull request lifecycle.

Describe a change. Claude Code ships it. You barely touch it. human0.ai https://human0.ai/open-source · the reviewer action https://github.com/human0-ai/code-review Fork this template and your repo runs on a self-driving loop. You say what you want — in plain language, from your laptop or your phone. Claude Code does the rest. It researches the code. It makes the change. It writes the docs. It opens a pull request. Then an AI reviewer checks the work. If something's off, the agent fixes it and tries again. It loops on its own until the review passes. Then it merges. You step in twice: to say what you want, and to say "go." What you get out of the box: — your rules, read by every agent on every run. Write them once. AGENTS.md / CLAUDE.md An AI reviewer — checks every PR, comments inline, gives one verdict: APPROVE or REQUEST CHANGES . An autonomous workflow — open a draft PR, watch the preview, say "go." The agent clears the review and the PR merges itself. Built for Claude Code, including Claude Code on the web. The reviewer and rules work with Codex or any agent too. It's the same setup that runs human0 https://human0.ai itself — every commit reviewed and merged by AI. Why we build this way: Why AI Agents Should Be Defined as Code https://human0.ai/blog/why-ai-agents-should-be-defined-as-code/ . If you just want the AI reviewer on your current project, you don't need to fork anything. Add a credential and one workflow file — full steps in the code-review action README https://github.com/human0-ai/code-review set-it-up . Use this repo as a template the green Use this template button , then: Add a credential. In Settings → Secrets and variables → Actions , add one of: ANTHROPIC API KEY — an Anthropic API key https://console.anthropic.com/ , or CLAUDE CODE OAUTH TOKEN — a Claude.ai OAuth token claude setup-token . Edit to describe your project — its structure and rules. AGENTS.md Review — this is your reviewer's instructions. Tailor it to your project before you start relying on it. docs/ai-review.md Open a pull request. The reviewer runs on the next push. To let an approval merge on its own, enable auto-merge and require the AI review in your branch protection settings. For the reviewer to approve PRs which is what lets an approval auto-merge , GitHub must allow Actions to approve pull requests: Settings → Actions → General → Workflow permissions → enable "Allow GitHub Actions to create and approve pull requests." In an organization this is often locked at the org level — set it under Organization → Settings → Actions → General instead. You don't need the "Read and write" default token permission; the workflow already requests the write scopes it needs. | Path | What it's for | |---|---| AGENTS.md | Guidelines agents read every run. CLAUDE.md is a symlink to it. | docs/ai-review.md | The reviewer's prompt — edit it to change how the reviewer behaves. | .github/workflows/ai-review.yml | Runs the reviewer on every PR. | .github/workflows/task-gate.yml | Holds an agent's PR until its linked task is independently approved. | The reviewer checks the diff; the task gate https://github.com/human0-ai/task-gate checks the work was signed off by someone who didn't do it. It's a CI check that stays red until an agent's PR links a Human0 task that's been independently approved, so self-approved work can't merge. It only gates the Human0 app's PRs — human PRs pass through. There's nothing to configure — no secret, no env. Just mark task-gate a required status check so a red gate blocks the merge. If you're not running the Human0 platform, delete task-gate.yml — the reviewer stands on its own. The reviewer is just a prompt plus your AGENTS.md . To change the bar, tone, or project-specific rules, edit docs/ai-review.md . To teach it your conventions without touching the prompt, write them in AGENTS.md — it reads that on every run.
