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 / Environment variables

CLAUDE_CODE_RESTRICTED

A Claude Code environment variable, 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

New --restricted flag starts a locked-down session with no shell tools and no settings files.

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.248.

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. v2.1.248New --restricted session mode

    New --restricted flag starts a locked-down session with no shell tools and no settings files.

    named in this entry

  2. v2.1.248Restricted sessions drop implicit file allowances and cannot be talked out of a denial

    Restricted sessions drop implicit file allowances, and a denial can't be argued away.

    named in this entry

  3. v2.1.248Restricted sessions handled the same way whether set by flag or environment

    Setting CLAUDE_CODE_RESTRICTED now restricts a session exactly as --restricted does.

  4. v2.1.248Auto-memory is off in restricted sessions

    Restricted sessions never write auto-memory, regardless of your settings.

    named in this entry

  5. v2.1.248More environment variables carried into remote sessions

    More environment variables get carried into remote sessions; none are set by default.

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 environment variable in the inventory starting claude_code, 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 environment variable does. All environment variables.
