Lumen Doctor

Run a health check on the bundled Lumen semantic search setup for the current project.

Steps

1. Call the Lumen health_check tool to verify the embedding service is

reachable.

1. Call the Lumen index_status tool with path or cwd set to the current

working directory to check index freshness.

1. Report a concise summary:

• Embedding service status, backend, host, and model
• Index totals: files, chunks, last indexed time, stale or fresh
• Storage totals: unique vectors, shared references, deduplication ratio,

vector precision, database bytes, and reclaimable bytes

• Any MCP or plugin setup issue that blocks the tools

1. If no index exists yet, explain that the Lumen semantic_search tool seeds

the index on first use.

1. If the user wants eager indexing instead of waiting for the next search,

suggest running lumen index . in the repository root.

1. Interpret storage totals as collection-wide values shared by compatible Git

worktrees; file, chunk, freshness, and indexing values are project-local. A high deduplication ratio is expected and is not an index-health problem.
