[DOCS] Missing documentation for IS_DEMO environment variable

Documentation Type

Missing documentation (feature not documented)

Documentation Location

docs/en/settings.md

Section/Topic

Environment variables reference

Current Documentation

The "Environment variables" table in docs/en/settings.md currently lists CLAUDE_CODE_HIDE_ACCOUNT_INFO with the description:
"Set to 1 to hide your email address and organization name from the Claude Code UI. Useful when streaming or recording"

It does not currently list IS_DEMO.

What's Wrong or Missing?

According to main/CHANGELOG.md for version 2.1.0, a new environment variable was introduced:

"Added IS_DEMO environment variable to hide email and organization from the UI, useful for streaming or recording sessions"

However, IS_DEMO is missing from the environment variables reference table in docs/en/settings.md. Users relying on the documentation are unaware of this shorter/alternative variable for hiding account information.

Suggested Improvement

Please update the Environment Variables table in docs/en/settings.md to include IS_DEMO.

If IS_DEMO is an alias for CLAUDE_CODE_HIDE_ACCOUNT_INFO, please clarify this relationship in the description.

Suggested entry:
| Variable | Purpose |
| :--- | :--- |
| IS_DEMO | Hides email and organization from the UI (similar to CLAUDE_CODE_HIDE_ACCOUNT_INFO). Useful for streaming or recording sessions. |

Impact

Low - Minor confusion or inconvenience
