Adding New Tools

To monitor a new tool's changelog:

1. Add config in changelog-checks.ts:

   NEWTOOL: {
     url: 'path_to_raw_markdown_or_deployed_changelog',
     link: 'path_to_changelog',
     name: 'tool name',
   }

2. Create checker (use createChangelogChecker for markdown or write custom function for HTML):

   export const checkNewTool = createChangelogChecker(
     CONFIG.NEWTOOL,
     'newtool'
   );

3. Add to checks in sentinel.ts runChecks() function
