            const comment = `⚠️ **Claude Configuration Warning**

            You've modified Claude Code configuration files. These files contain the shared configuration for all contributors. Please revert this change if unintended. **ONLY modify these files if you need to change shared configurations that apply to everyone and have discussed this change with the TW team.**

            To override the Claude settings locally, use \`.claude/settings.local.json\` instead. This local file is gitignored and overrides the repo default.

            **For example, if you're changing AWS_PROFILE:**
            The default profile name is \`my-sandbox\`. If your AWS profile has a different name, override it locally instead of changing the shared file.

            Create or edit \`.claude/settings.local.json\` in the repo root and include the following lines:

            \`\`\`json
            {
              "env": {
                "AWS_PROFILE": "your-sandbox-name"
              }
            }
            \`\`\`
            `;
