Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Explain this complex logic.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai explain this code block.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and explain its main purpose.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Bug: Source Naming Mismatch Causes Confidence Issues

In GeneralKnowledgeAgent, the sources array is populated with 'knowledge base' and 'web search', but the confidence calculation logic checks for 'knowledge_base' and 'web_search'. This inconsistency prevents the correct, higher confidence values from being assigned based on the actual sources used.

	}
	}
	// Use web search for current information or if knowledge base has no results
	if (needsWebSearch || !context) {
	const webSearchTool = this._tools.get('generalWebSearch');
