[DOCS] Model configuration docs omit `/effort auto` reset command

Documentation Type

Missing documentation (feature not documented)

Documentation Location

https://code.claude.com/docs/en/model-config

Section/Topic

Effort-level controls and reset behavior.

Current Documentation

The effort section currently documents:

Three levels are available: low, medium, and high.

And setting methods:

In /model: use left/right arrow keys to adjust the effort slider Environment variable: set CLAUDE_CODE_EFFORT_LEVEL=low|medium|high * Settings: set effortLevel in your settings file

No /effort command entry or /effort auto reset behavior is documented.

What's Wrong or Missing?

Release v2.1.72 states users can run /effort auto to reset effort to default.

The model configuration page explains low/medium/high but omits the command-based reset path, leaving users without a documented way to return from an explicit override to automatic/default behavior.

Suggested Improvement

Add a short subsection under "Adjust effort level" that documents:

1. /effort low|medium|high (if supported command syntax should be listed explicitly).
2. /effort auto resets to default model behavior.
3. How /effort auto interacts with /model slider and CLAUDE_CODE_EFFORT_LEVEL.

Impact

Medium - Makes feature difficult to understand
