+
+WHAT IS TELEX?
+Telex is a premium AI-powered development environment for WordPress.
+It enables agents to generate and edit WordPress blocks, plugins, and
+themes through conversational commands.
+
+Commands available with Telex:
+  • telex gen block <name>    - Generate WordPress blocks
+  • telex gen plugin <name>   - Generate WordPress plugins
+  • telex gen theme <name>    - Generate WordPress themes
+  • telex edit block <name>   - Edit blocks conversationally
+  • telex chat                - WordPress development assistance
+
+WHY IS IT UNAVAILABLE?
+Telex is not included in the current WordPress.com plan.
+
+SUGGESTED AGENT ACTION:
+1. Inform the user that Telex is required for this task
+2. Explain what Telex does and why it would be helpful
+3. Offer to open the upgrade page for them
+4. If user agrees, open: https://wordpress.com/plans?feature=telex&utm_source=studio&utm_medium=agent&utm_campaign=telex-upsell
+
+ALTERNATIVE APPROACHES:
+Consider if the task can be accomplished without Telex using:
+  • Direct file editing with available tools
+  • WordPress CLI commands (wp-cli)
+  • Manual block/plugin development guidance
