Semantic Code Search FAQs

Question 1

Is this skill useful for legacy codebases?

Accepted Answer

Yes, it is specifically designed to help developers explore unfamiliar or poorly documented codebases where naming conventions may be inconsistent or unknown.

Question 2

What should I do if the search tool is not listed?

Accepted Answer

If mcp__cocoindex-code__search is not available, it is considered a configuration error (BLOCKED) rather than a fallback scenario, and you should check your MCP server settings.

Question 3

How does semantic search differ from grep?

Accepted Answer

Grep finds exact text matches, while semantic search uses AI to understand the meaning and intent behind the code, finding relevant logic even if the specific names or string literals don't match your query.

Question 4

When should I use semantic search over standard search tools?

Accepted Answer

Use semantic search when you know what the code *does* but not what it is *called*. Use standard Grep or Glob when you have exact identifiers, filenames, or specific string literals.

Question 5

Does this skill require manual indexing or installation?

Accepted Answer

No, the skill utilizes the CocoIndex Code MCP server which is bundled via .mcp.json and launches automatically using uvx, providing a zero-pre-installation experience.
