It sits in the same lists as other switches that turn features off, such as `CLAUDE_CODE_DISABLE_WEB_FETCH` and `CLAUDE_CODE_DISABLE_PROACTIVITY`.\n\n**Why**\n\nA switch like this matters most to managed or locked-down setups, where an administrator wants to turn a feature off for everyone.\n\n- Area: File Mentions\n- Names: `CLAUDE_CODE_DISABLE_FILE_MENTIONS`\n- Tier: Use it now\n- Useful: 5\/5\n- Signal: 2\/5\n- Scope: both\n- Heads-up: no"}
