from line 228
228228| `CLAUDE_CODE_DISABLE_ATTACHMENTS` | Set to `1` to disable attachment processing. File mentions with `@` syntax are sent as plain text instead of being expanded into file content |
229229| `CLAUDE_CODE_DISABLE_AUTO_MEMORY` | Set to `1` to disable [auto memory](/docs/en/memory#auto-memory). Set to `0` to force auto memory on even when `--bare` mode or [`autoMemoryEnabled: false`](/docs/en/settings-reference#automemoryenabled) would otherwise disable it. When disabled, Claude does not create or load auto memory files |
230230| `CLAUDE_CODE_DISABLE_BACKGROUND_TASKS` | Set to `1` to disable all background task functionality, including the `run_in_background` parameter on Bash and subagent tools, auto-backgrounding, and the Ctrl+B shortcut |
231| `CLAUDE_CODE_DISABLE_BEDROCK_CONTENT_TYPE_DEFAULT` | Set to `1` to stop Claude Code from treating an [Amazon Bedrock](/docs/en/amazon-bedrock) streaming response with a missing or empty `Content-Type` header as the binary `application/vnd.amazon.eventstream` format. Amazon Bedrock always sends that header, so when it's absent, a [proxy stripped it](/docs/en/amazon-bedrock#streaming-errors-behind-a-gateway-or-proxy) and by default Claude Code decodes the body as the binary format anyway. Set this variable only when the proxy strips the header and also re-emits the body as server-sent events; Claude Code then reads the body as server-sent events instead. Requires Claude Code v2.1.239 or later |
231232| `CLAUDE_CODE_DISABLE_BEDROCK_CONTENT_TYPE_GUARD` | Set to `1` to skip the check that an [Amazon Bedrock](/docs/en/amazon-bedrock) streaming response carries the `application/vnd.amazon.eventstream` content-type. Without this variable, a response with a different content-type fails with an error naming that content-type, which means a [gateway or proxy is transforming the response](/docs/en/amazon-bedrock#streaming-errors-behind-a-gateway-or-proxy). Set it only when the gateway rewrites the `Content-Type` header but passes the binary event-stream body through unmodified; if the body itself was transformed, requests fail with `Truncated event message received` instead. Requires Claude Code v2.1.208 or later |
232233| `CLAUDE_CODE_DISABLE_BG_EXIT_HANDOFF` | Set to `1` to stop a [background session's](/docs/en/agent-view) running background shell commands, dynamic workflows, and, as of v2.1.198, background subagents when the [supervisor](/docs/en/agent-view#the-supervisor-process) stops, restarts, or updates that session's process, instead of handing them to the session's next process. Affects only that handoff: backgrounding a session with `←` or [`/background`](/docs/en/agent-view#from-inside-a-session) still carries in-flight work over, and `CLAUDE_DISABLE_ADOPT` turns off both. Requires Claude Code v2.1.196 or later |
233234| `CLAUDE_CODE_DISABLE_BG_SHELL_PRESSURE_REAP` | Set to `1` to stop Claude Code from terminating [background shell commands](/docs/en/interactive-mode#background-bash-commands) when the operating system reports memory pressure. By default, on macOS and Linux, Claude Code terminates a background shell started in the main session on a memory-pressure signal once the session has been idle for 30 minutes and no turn or subagent is running. Windows has no memory-pressure signal, so this variable has no effect there. Requires Claude Code v2.1.193 or later |

318319| `CLAUDE_CODE_PLUGIN_GIT_TIMEOUT_MS` | Timeout in milliseconds for git operations when installing or updating plugins (default: 120000). Increase this value for large repositories or slow network connections. See [Git operations time out](/docs/en/plugin-marketplaces#git-operations-time-out) |
319320| `CLAUDE_CODE_PLUGIN_KEEP_MARKETPLACE_ON_FAILURE` | Set to `1` to skip the re-clone attempt and keep using the existing marketplace cache when a `git pull` fails. Useful in offline or airgapped environments where re-cloning would fail the same way. See [Marketplace updates fail in offline environments](/docs/en/plugin-marketplaces#marketplace-updates-fail-in-offline-environments) |
320321| `CLAUDE_CODE_PLUGIN_PREFER_HTTPS` | Set to `1` to clone GitHub `owner/repo` shorthand sources over HTTPS instead of SSH. Applies to plugin install and update, and to `/plugin marketplace add` and `update`. Useful in CI runners, containers, or any environment without a configured SSH key for `github.com` |
321| `CLAUDE_CODE_PLUGIN_SEED_DIR` | Path to one or more read-only plugin seed directories, separated by `:` on Unix or `;` on Windows. Use this to bundle a pre-populated plugins directory into a container image. Claude Code registers marketplaces from these directories at startup and uses pre-cached plugins without re-cloning. See [Pre-populate plugins for containers](/docs/en/plugin-marketplaces#pre-populate-plugins-for-containers) |
322| `CLAUDE_CODE_POWERSHELL_RESPECT_EXECUTION_POLICY` | Set to `1` to stop Claude Code from passing `-ExecutionPolicy Bypass` when spawning PowerShell for tool calls, hooks, and status line commands, and respect the machine's effective execution policy instead. By default Claude Code bypasses exe
