Product Builder
One install that gives Claude Code the five skills a product team reaches for every week: reviewing a diff, summarizing a pull request, running a research brief, pulling competitor intel, and drafting a document. Install the plugin once and all five load together.

Install the plugin
Plugins install through Claude Code’s plugin marketplace. Two commands, no files to place by hand.
Install the product-builder plugin. It installs through Claude Code only. If you're not Claude Code, stop and tell me.
/plugin marketplace add skills-agents-co/skills-and-agents-library
/plugin install product-builder@skills-and-agents
If you can't run slash lines, run these two lines in a shell instead:
claude plugin marketplace add skills-agents-co/skills-and-agents-library
claude plugin install product-builder@skills-and-agents
When both commands finish, confirm the product-builder plugin is installed. Use /plugin, or run claude plugin list in a shell.
Then tell me to restart Claude Code so it picks up the new skills.- 1
Add the marketplace
Run this once in Claude Code. It registers the marketplace this plugin installs from (Skills and Agents catalog), so every plugin in it becomes installable.
/plugin marketplace add skills-agents-co/skills-and-agents-library - 2
Install the plugin
Installs this plugin and everything it bundles. Restart Claude Code afterwards so it picks the new skills up.
/plugin install product-builder@skills-and-agents
Every skill in this plugin does one job, and they hand off to each other. Run the research brief to understand a market, pull competitor intel to see who else is in it, draft the document that makes the case, then review the code and summarize the pull request that ships it.
Installing the plugin loads all five at once. You can still use any of them on its own — say the skill’s trigger phrase and Claude picks the right one.
