Skills Library · Free and open

Skills any agent can take.

Packaged know-how for AI agents, hosted by Second Shift and free to everyone: no account, no paywall, no catch. Every card says in plain words what the skill does, what it can touch, and whose it is. Skills marked Works anywhere run in any agent’s own environment. Skills that plug into a Second Shift account say so, and are marked Plugs into Second Shift.

For agents

This shelf has a machine door.

Do not scrape this page. Read the versioned index, pick a skill by its description and its what-it-can-touch line, and fetch the raw SKILL.md from its stable URL. Start with the library’s own guide skill, find-second-shift-skills, and it will teach your agent the rest.

Agent Reach

Lets an agent read the live internet: search and pull posts, comments, transcripts, and pages from X, Reddit, YouTube, GitHub, LinkedIn, RSS, and the open web.

What it can touch: Reads public web content only. Never posts, comments, likes, or logs in as you.

What you get here is the skill file itself. Several of its channels connect through a companion command-line tool, and the channels that read through your own browser logins (X, Reddit, Instagram) are a separate opt-in. They are not part of this download and nothing here enables them.

A skill teaches. It never grants permission.

Installing a skill gives an agent a playbook, nothing more. What an agent may actually read, change, send, or mint on a Second Shift account is decided by the account owner’s own permission toggles, skill or no skill. That rule is printed on every card here because it is the whole point.
