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_AUTO_CONNECT_IDE

A Claude Code environment variable, read out of the shipped bundle. It has been in the build since v2.1.138, including the newest one read.

What it is

Override automatic [IDE connection](/docs/en/vs-code). By default, Claude Code connects automatically when launched inside a supported IDE's integrated terminal. Set to false to prevent this. Set to true to force a connection attempt when auto-detection fails, such as when tmux obscures the parent terminal. Takes precedence over the [autoConnectIde](/docs/en/settings-reference#autoconnectide) global config setting

Anthropic's own wording. Read off Environment variables, captured 2026-08-28.

A row reading never mined is a release with no archived bundle behind it. Nothing was read out of it, so nothing here says whether the name was in it. A declared type or a default is only ever what that release's own bundle stated.

Changelog entries naming it

No changelog entry here has ever named it. That is a statement about what has been written, not about the name: it has been in the build since v2.1.138 without anybody writing a line about it.

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_auto, up to twelve of them.

CLAUDE_CODE_AUTO_COMPACT_WINDOWSet the [auto-compact window](/docs/en/model-config#set-the-auto-compact-window) in tokens, from 100000 to 1000000. Accepts a plain integer such as 500000 only: a value like 500k reads as 500 and clamps to the 100K minimum. Takes precedence over the /autocompact command, the --autocompact flag, and the autoCompactWindow setting. The status line's used_percentage always measures against the model's full context window, so once this variable is set, that percentage no longer indicates when compaction will run 2.1.138 CLAUDE_CODE_AUTO_MODE_ARTIFACT_CONSENT_RULEThe rule stopping Claude publishing artifacts you didn't ask for can now be removed remotely. never mined CLAUDE_CODE_AUTO_MODE_CLASSIFY_ASK_USER_QUESTIONIn auto mode, a question can be classified and handled instead of halting the run. never mined CLAUDE_CODE_AUTO_MODE_EXTERNAL_PERMISSIONSNo description from anybody. 2.1.160 CLAUDE_CODE_AUTO_MODE_MODELNo description from anybody. 2.1.160 CLAUDE_CODE_AUTO_MODE_OUTCOME_CODESThe switch controlling outcome codes in auto mode now runs through a wrapper with an empty branch. never mined CLAUDE_CODE_AUTO_MODE_REPO_VISIBILITYAuto mode's awareness of whether your repo is public now has its own environment variable and config field. never mined

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.
