# One Agent a Day > One working agent. Every day. Free. Every day, one free AI agent you can actually run: a prompt, a config, or a small template, plus a 30-second demo. For people who build agents, ship code, and play games. The catalog is one Markdown file per agent. Each public page is `/agents/`. Prompts are free under CC-BY-4.0. ## Agents - [Steam Backlog Picker](https://oneagentaday.com/agents/steam-backlog-picker): Paste your Steam library and the evening you actually have. Get one game to launch, two backups, and a reason you can argue with. - [Roast My GitHub](https://oneagentaday.com/agents/roast-my-github): Hand it a GitHub profile and get a sharp, affectionate roast of the work, plus one fix worth doing this week. - [Patch Notes Explainer](https://oneagentaday.com/agents/patch-notes-explainer): Paste any patch notes. Get the 20-second version, what changed for your role, and whether tonight is a play night. - [Vibe-code Security Checker](https://oneagentaday.com/agents/vibe-code-security-checker): A review prompt for vibe-coded diffs.

Get what broke, what to change in the request, and whether a retry will help. - [Tutorial Gap Finder](https://oneagentaday.com/agents/tutorial-gap-finder): Paste the tutorial's outline and the step where you got stuck.

Get three replies that stay in that voice. - [Automation Recipe Writer](https://oneagentaday.com/agents/automation-recipe-writer): Describe a repetitive job.

Get three copy-paste examples, the flags that matter, and the ones that should stay hidden. - [Error Message Poet](https://oneagentaday.com/agents/error-message-poet): Paste a harsh error.
