DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Reference / Settings keys

permissions.defaultMode

A Claude Code settings key, read out of the shipped bundle. No mined inventory carries it: everything below comes from what this site has written about it.

What it is

Set the [permission mode](/docs/en/permission-modes#which-mode-a-session-starts-in) new sessions start in

Anthropic's own wording. Read off Claude Code settings reference, captured 2026-08-28.

Presence across releases

The miner has never read a build containing this name. It is here because a changelog entry of ours names it, which is evidence that it existed and not evidence of which releases carried it. The inventory starts at v2.1.138 and everything older than that was never mined.

Changelog entries naming it

  1. v2.1.238Carrying and reporting your local permission mode in remote sessions is gated off

    Remote sessions could inherit your local permission mode and effort level, but no value is compiled in.

  2. v2.1.225Auto-default nudge actually flips the mode, and reports the outcome

    Saying yes to the auto-mode prompt now actually saves auto as your default permission mode.

  3. v2.1.225VS Code-owned sessions get their own settings defaultMode handling

    In VS Code sessions, unsafe default permission modes from settings are refused and fall back to normal.

Documentation pages

A reference table page is one whose own table defines this name, and it is where the description above came from. A page that mentions it carries the name somewhere in its text and may say nothing about it at all. Every page carrying it.

Names beside it

Every settings key in the inventory starting permissions, up to twelve of them.

Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the settings key does. All settings keys.
