Marketplace

The marketplace helps you add ready-made mind templates and trusted sources to Chamber. It is the fastest way to start with a useful specialist.

Mind templates

A mind template is a complete starter helper. The public Genesis marketplace contains ready-made personalities such as Alfred, Annie, Commander Data, Grace, Lucy, Maple, Mia, Miss Monet, Moneypenny, Pulse, Tracker, and Trixie. A private team marketplace can offer a smaller approved set for your organization.

  • Use a template when you want a specialist without writing its profile yourself.
  • Read the name, role, voice, and description before you add it.
  • After adding a mind, you can still adjust its name, style, memory, and work habits.

Add to Chamber button

Marketplace pages can show an Add to Chamber button or badge. It usually opens a friendly web page first, then hands the marketplace link to the installed Chamber app.

1

Click the badge

The button points at an install page, such as https://chmbr.dev/install.html?registry=....

2

Open Chamber

The install page creates a chamber://install?registry=... link. Your browser may ask before opening Chamber.

3

Approve the source

Chamber asks whether to add the Genesis marketplace. Add it only when you trust the GitHub repository.

Marketplace sources and private access

A marketplace source is a GitHub repository Chamber can read. The default public source uses the same structure as C:\src\genesis-minds. A private or team source can use the same structure, like C:\src\internal-genesis-minds, but require you to sign in with an account that has repository access.

  • Public marketplaces are good for general starter minds.
  • Private marketplaces are good for team-approved minds and organization tools.
  • If a private source cannot be read, sign in to Chamber with an account that can access the repository.
  • Disable or remove a source when you no longer trust it or no longer need it.

What the marketplace JSON means

You do not need to edit JSON to use the marketplace, but these files explain what Chamber is reading when it previews a source.

marketplace-config.json Identifies the repository as a marketplace and provides shared metadata such as name, description, version, and owner.
plugins/genesis-minds/plugin.json Lists the mind templates and optional tools available from that marketplace.
minds/*/mind.json Describes one mind: its display name, role, voice, version, root folder, agent file, and required files.
requiredFiles Tells Chamber which template files must be copied when the mind is created.

Marketplace tools

A marketplace can also offer command-line tools for minds to use. Chamber lists them from plugin.json, installs them when needed, and includes safe usage notes in the mind's tool instructions.

npm-global Installs a named npm package globally, such as a Work IQ-style tool with a package name, version, command, help command, and optional preflight step.
github-release-asset Downloads a release asset from GitHub, checks its SHA-256 hash, and places the executable in Chamber's tools bin. On Windows this can be an .exe file such as a Teams, Mail, or Calendar CLI.
agentInstructions Explains to the mind when to use the tool, how to authenticate, and which actions need explicit user intent.

What to review before installing tools

  • The marketplace source and repository owner.
  • The tool description and command name.
  • Whether it installs from npm or a GitHub release asset.
  • For release assets, the platform, architecture, file name, and checksum.
  • Any sign-in, license, or account requirements the tool mentions.
