settings.json

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

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. v2.1.242Session spawn aborts on host-specific write paths committed to a repo

   A committed settings file granting host-specific write paths blocks session startup with instructions.

   named in this entry

2. v2.1.227Settings can be pre-loaded through the v5 storage backend

   Settings can be pre-read through the new storage backend, skipping re-parsing when unchanged.

3. v2.1.222Resume snapshots carry user settings without plugin keys

   Resumed sessions now carry your settings files along, with plugin registrations stripped out.

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.

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.
