What it does

Adds a helper for building plugins for the Atlas Agent. When asked to create a plugin, the agent runs bundled Python scripts that generate a standard folder with a plugin.json manifest, optionally add companion folders (skills, hooks, scripts, assets, MCP and app config), register the plugin in a marketplace.json file so it shows up in the app's list, and validate the result. It can also bump a local plugin's version with a cachebuster suffix so changes reinstall during development.

Great for

  • Developers building personal or team plugins for Atlas Agent
  • Teams that keep a shared repo marketplace and need consistent plugin scaffolds

Skip it if

  • Users who are not building Atlas Agent plugins, since it only applies to that plugin format
  • Editing an existing marketplace.json by hand without checking the script output, because the scripts write to user files and an incorrect --force or path can overwrite an existing marketplace entry

Try asking

  • “Create a new Atlas plugin called Invoice Tools and add it to my personal marketplace”
  • “Scaffold a plugin with skills and scripts folders in ~/plugins”
  • “Validate the plugin I just generated before I reinstall it”
  • “Bump the cachebuster on my local plugin so Atlas picks up my changes”

Get better results

  • Review the generated plugin.json and marketplace.json before reinstalling, since the scripts write directly to your home directory.
  • Use the default personal marketplace unless you specifically need a repo or team marketplace, and avoid --force unless you mean to replace an entry.
