incomplete or inconsistent names for matcher for hook documentation
URL of the page with the issue
https://geminicli.com/docs/hooks/writing-hooks/
What is the problem?
The list of tool names is incorrect or incomplete.
Under https://geminicli.com/docs/hooks/writing-hooks/#configuration
you can see matcher that matches with startup and "matcher": "exit|logout" in a later example.
Whereas other examples are CamelCased like "WriteFile|Edit"
In my own testing I found that the json output is
"tool_name":"replace","tool_input":{"file_path":"/Users/kimsia/Projects/opus-gemini-orchestrator/.ogo/thoughts/shared/01_research/knowledge_base/gemini_cli/2025-12-15_how_to_add_hooks_to_gemini_cli.md",
"AfterTool","timestamp":"2025-12-15T07:08:13.867Z","tool_name":"write_file","tool_input":{"file_path":".ogo/thoughts/shared/01_research/knowledge_base/gemini_cli
using snake style like replace, write_file for tools
In https://geminicli.com/docs/hooks/#tool-name-mapping
it gives only a short list of four tool names and all in CamelCased. I find this hard to believe.
What did you expect to happen?
I expect documentation for matcher to show the exhaustive list of possible tool_names and I expect the names to be of consistent notation format. Either CamelCased or snake_style
