karpathytalk-community — Claude Code skill: run KarpathyTalk

What karpathytalk-community does

KarpathyTalk is a developer social network written in Go. Posts are markdown, and the social layer covers likes, reposts, replies and follows. The skill takes an agent through setup: register a GitHub OAuth App, build the binary from ./cmd/karpathytalk, export GITHUB_CLIENT_ID, GITHUB_CLIENT_SECRET and BASE_URL, then start the server. Production steps are included too — copying the binary plus templates and static to a host, TLS configs for Caddy and nginx, and a systemd unit.

The other half covers the API. Reads need no auth: curl https://karpathytalk.com/api/posts returns JSON, while /api/posts/{postID}.md gives markdown for a person or an agent. Go samples show how to decode the timeline into a Post struct and how to pull a user's posts as markdown. Storage is a single SQLite file, so you can open it with sqlite3 for backups or analytics.

GitHub sign-in fails without both GITHUB_CLIENT_ID and GITHUB_CLIENT_SECRET, and the OAuth callback has to point at http://localhost:8080/auth/callback. Posts cap at 10,000 characters and 30 per hour, replies at 5,000 and 60, and images at 5 MB in PNG, JPEG, GIF or WebP.
