Issue Summary

This issue reports that the model configuration page omits the /effort auto command for resetting effort to the model default, and that the interactive-mode page's built-in command table lacks any /effort entry. The reporter references release v2.1.72 as the source of the /effort auto feature and identifies two pages as affected.

Verification Results

Claim 1: /effort auto reset path is not documented on the model-config page

Status: RESOLVED

At https://code.claude.com/docs/en/model-config, line 138, the "Adjust effort level" subsection currently reads:

/effort: run /effort low, /effort medium, /effort high, or /effort max to change the level, or /effort auto to reset to the model default

The documentation now fully documents /effort auto alongside the other effort levels and explicitly describes its behavior as resetting to the model default.

Verdict: The missing documentation has been added. The claim no longer holds.

---

Claim 2: The interactive-mode built-in command table has no /effort entry (lines 95–139 at filing time)

Status: RESOLVED

The current https://code.claude.com/docs/en/interactive-mode no longer contains an inline built-in commands table listing individual commands. Lines 87–91 now redirect users to the dedicated commands reference:

See the commands reference for the full list of built-in commands.

The commands reference at https://code.claude.com/docs/en/commands, line 31, contains a comprehensive entry for /effort:

/effort [low|medium|high|max|auto] — Set the model effort level. low, medium, and high persist across sessions. max applies to the current session only and requires Opus 4.6. auto resets to the model default. Without an argument, shows the current level. Takes effect immediately without waiting for the current response to finish.

The interactive-mode page's architecture changed: it now delegates command listings to the dedicated commands reference rather than embedding a table inline. The /effort command, including /effort auto, is fully documented there.

Verdict: The table referenced in the issue no longer exists in its original form. The replacement commands reference fully covers /effort auto. The gap is closed.

Conclusion & Recommendation

Primary Concern: The model-config page and interactive-mode page were missing documentation for the /effort auto command introduced in v2.1.72, leaving users without a documented path to reset effort to the model default.

Resolution Status: RESOLVED

Recommendation: CLOSE

Both pages have been updated: model-config now documents /effort auto inline in the "Adjust effort level" subsection, and the interactive-mode page now delegates to a dedicated commands reference that includes a complete /effort entry covering all arguments including auto.
