gemini extensions install error extension failed to load context missing fails

Fixes Gemini CLI extension installs where the extension fails to load because its context is missing. Use when install completes or partly completes but startup reports the extension failed to load or a missing context file. Not for a network download failure during install.

Run the extensions list command and note the exact extension name and its reported state.

Open the installed extension folder under the CLI extensions directory and list its contents.

Read the manifest and copy the context file name it declares, then compare it with the actual file name on disk, including case.

If any declared file is missing, remove the extension and reinstall it from the original source address, installing from the repository root rather than a subfolder.

Start a new CLI session instead of resuming an old one, and watch the startup output for the extension name.

Run one command the extension provides.
