The classic GitHub tutorial repository, powered by Claude Code
This is the canonical Hello-World repository originally created by @octocat — GitHub's mascot — as part of the introductory “Hello World” tutorial for new developers learning Git and GitHub.
The repository now serves as a lightweight agent-runner sandbox: a minimal git working directory that hosts a Claude Code agent session. The agent uses this repo as its operational context — reading, editing, and committing changes just as a human developer would.
The sole tracked change ensures the README file ends with a proper trailing newline —
a small but meaningful fix for POSIX compliance.
The .agent-runner/ directory bootstraps a Claude Code session inside this
repository. It bundles the @anthropic-ai/claude-code Node.js package along
with a pre-built Linux x64 binary — no global install required.
Claude Code is an agentic coding tool from Anthropic. It reads and writes files, runs shell commands, manages git, and orchestrates complex multi-step software tasks — all within the context of this repository.
Repositories like this are ephemeral by design. The agent-runner creates a fresh checkout for each session, giving the agent an isolated, disposable workspace. Any changes the agent makes live here and are cleaned up when the session ends.
