Skills

Skills are short, auto-triggering playbooks that teach an AI agent how to use Release Notes Index. When you ask a release-shaped question, your agent loads the matching skill and follows it.

They work in Claude Code, Codex, Cursor, OpenCode, and any other agent that supports the agent skills format.

Install

Standalone (any agent)

Run this from the root of any project where you want the skills, using the skills CLI:

npx skills add buildinternet/releases

Your agent picks them up on the next session.

Claude Code plugin

If you're on Claude Code and also want the bundled MCP connection and /releases command:

/plugin marketplace add buildinternet/releases
/plugin install releases@releases

Claude Code doesn't auto-update third-party plugins by default. To get new skills as they ship, run /plugin, open Marketplaces, select releases, and turn on auto-update. To update once by hand, run /plugin marketplace update releases to refresh the listing. Then run claude plugin update releases@releases --scope user, using the scope you installed with, and restart Claude Code.

What the skills do

releases-mcp

Triggers when you ask about a library or product release: "what changed in Next.js 15?", "latest Tailwind releases", "compare Bun vs Deno." Your agent answers from current registry data instead of stale training data.

releases-cli

Triggers when you mention the releases CLI or run a releases command. Helps your agent pick the right subcommand and flags.

analyzing-releases

Triggers on landscape questions: "what is X shipping lately", "how does X compare to Y", "what's new in observability." Picks a set of products, fetches their recent releases, and summarizes the themes.

creating-releases-json

Triggers when you want to list your own product: "add a releases.json", "get indexed on Releases Index", "make us a manifest for our website." It finds where you actually publish release notes, writes a valid v2 manifest, and walks through publishing it at /.well-known/releases.json.

Install just this skill (or grab the copy buttons on the submit page):

npx skills add buildinternet/releases --skill creating-releases-json

See Listing your product for the format and the paste-ready agent prompt.

More from Build Internet

buildnotes is a sibling skill for coding agents. It reads a feature's issues, pull requests, and reviews, then writes them up as a post, video, or slides.

npx skills add buildinternet/buildnotes

Operator skills

These are for people running or maintaining the registry itself: onboarding sources (finding-changelogs, managing-sources), the parse pipeline (parsing-changelogs, classify-media-relevance), and bulk maintenance (seeding-playbooks and friends). They live with the backend in the releases monorepo under .claude/skills/. Claude Code picks them up automatically in a checkout, or you can install them anywhere:

npx skills add buildinternet/releases

Most need an admin API key to do anything.
