Lumen Reindex

Refresh or rebuild the bundled Lumen index for the current project.

Steps

1. Call the Lumen `index_status` tool for the current working directory so you can report the current state before making changes. 2. If the user wants the index refreshed or seeded, call the Lumen `semantic_search` tool with a broad natural-language query and set `path` or `cwd` to the current working directory. The search tool refreshes stale or missing indexes automatically. 3. If the user explicitly asks for a clean rebuild, explain the options and run one via the shell:

  • `lumen index --force .` — reprocesses every file for the current project

without wiping other worktrees or their shared vectors. Prefer this.

  • `lumen clean --days 0 && lumen index .` — deletes every cached index not

held by an active indexer lock before rebuilding; locked collections are skipped and counted in the summary. Use only when the user asks for a full wipe.

  • `lumen clean` — removes indexes for projects that no longer exist or have

not been used in 30 days. Use to reclaim disk space, not to rebuild the current project. 4. After the refresh or rebuild, report the new index status, including vector precision, unique vectors, shared references, deduplication ratio, database bytes, and reclaimable bytes when available.
