Conflict when installing MCP and Agent Skills: Extension "firebase" is already installed

[raky291]

There is a naming conflict when attempting to install both the Firebase MCP extension and the Agent Skills extension. It appears that both extensions use the same identifier ("firebase") within the Gemini CLI, preventing them from coexisting in the same environment.

Steps to Reproduce

Install the first extension:

gemini extensions install https://github.com/gemini-cli-extensions/firebase/

Attempt to install the second extension:

gemini extensions install https://github.com/firebase/agent-skills

Actual Behavior

The CLI returns the following error message during the second installation attempt: Extension "firebase" is already installed. Please uninstall it first.

Expected Behavior

Users should be able to install both extensions simultaneously, as they provide different sets of functionalities (one for MCP and another for Agent Skills), even if they both interface with Firebase.

Environment Data

• Tool: gemini-cli
• Error Message: Extension "firebase" is already installed. Please uninstall it first.

Potential Cause

Both repositories likely define their extension ID as firebase in their respective configuration files, causing the CLI to block the second installation to prevent overwriting.

Hey @raky291! These 2 extensions are actually redundant, and we recommend just using this one going forward. We've not removed the other repo yet, but we plan to turn it down soon. We wanted to move all of our various agent plugins for Gemini CLI, Claude, Cursor, etc to a single repo under the Firebase organization, to make it a little easier to maintain long term.

I'll come back and close this once we've turned down the other repo properly.
