Please add proper file search or reading guideline including indexing state context.

What specific problem does this solve?

Roo should not use semantic search if the indexing is not done; it sometimes tries to use semantic search even if the indexing is not done. By default, Roo doesn't always use semantic search; instead, it tries to use read file, which is quite ok, as that mimics an expert dev. But when trying to use semantic search, it should not happen if the indexing is not completely done.

PR #5663 has been created to address this issue

[daniel-lxs]

I've been thinking about this and maybe we should check the indexing status when the tool is actually used instead of hiding it from the tool list entirely.

If we keep codebase_search always available and do a runtime check (like codeIndexManager.state !== 'Indexed'), Roo could fall back to file reading when needed and also explain what's going on.

This would:

• Make state transitions smoother (e.g. indexing finishes mid-convo)
• Keep the logic in one place (inside the tool)
• Help users understand why semantic search isn’t used instead of just silently not using it

Something like this in the tool handler:

if (codeIndexManager.state !== 'Indexed') {
  return {
    success: false,
    message: `Semantic search isn't ready yet (currently ${codeIndexManager.state}).`
  }
}

Let me know what you think.
