Show errors when custom command .toml files have syntax errors #7537
Description
What happened?
- Create malformed .toml with custom command (I was able to reproduce with
"""'as the last line, where as"""works fine):
> cat ~/.gemini/commands/investigate.toml
description = "Asks the model to investigate a bug in relation to this project."
prompt = """
Analyze the project directory. Take note of important files, details, etc and summarize it into tmp/PROJECT.md.
"""'
- Call
geminicommand - gemini starts, custom
/investigatecommand doesn't appear, there's no visibility that the~/.gemini/commands/investigate.tomlhas a syntax error
What did you expect to happen?
I want to see a red error saying that the ~/.gemini/commands/investigate.toml has a syntax error, and the line with the error.
