+# desktop-applications Specification
+
+## Purpose
+
+Provisions everyday desktop GUI applications (chat, communication, and music clients) through the shared home-manager profile, mirroring how `developer-environment` provisions CLI tooling but for user-facing graphical applications instead.
+
+## Requirements
+
+### Requirement: Desktop GUI applications are provisioned via the shared home profile
+The shared home-manager profile SHALL include Slack, Discord, Spotify, and teams-for-linux as GUI application packages, available wherever that profile is activated and the underlying package supports the current system.
+
+#### Scenario: GUI app available after activation
+- **WHEN** the shared home profile is activated on a system for which a given desktop application's package is supported
+- **THEN** that application is available without any additional manual installation step
+
+### Requirement: Packages unsupported on the current system are skipped, not failed
+A desktop application package that has no supported build for the currently evaluated system SHALL be omitted from the provisioned package set rather than causing profile evaluation or activation to fail.
+
+#### Scenario: Unsupported package excluded without failure
+- **WHEN** the shared home profile is evaluated on a system for which one of the desktop application packages (e.g. an `aarch64-linux` target lacking a Discord, Spotify, or Slack build) has no supported build
+- **THEN** that package is excluded from the provisioned set and the rest of the profile evaluates and activates successfully
+
+### Requirement: teams-for-linux is Linux-only
+teams-for-linux SHALL be provisioned only on Linux systems, consistent with its scope as a Linux-only Microsoft Teams client.
+
+#### Scenario: Excluded on a non-Linux system
+- **WHEN** the shared home profile is activated on a non-Linux system
+- **THEN** teams-for-linux is not included in the provisioned package set
