grepai-storage-gob

Set the store backend to gob in .grepai/config.yaml, which is the default configuration. Then run grepai init followed by grepai watch to create the index.gob file containing vector embeddings.

GOB is Go's native binary serialization format used by GrepAI to store vector embeddings, file metadata, and chunk information in a single local file. It requires no external services and is the default storage backend.

Migrate when the index exceeds 1 GB, when you need concurrent access from multiple users, when sharing an index across a team, or when the codebase grows beyond roughly 50,000 files. Update the backend in config.yaml and re-index.

Sharing is not recommended because the index requires an identical embedding model, contains absolute file paths, and may reflect different code versions. Each developer should run their own grepai watch to generate a local index.

Delete the corrupted index files and re-index from scratch. Remove .grepai/index.gob and .grepai/symbols.gob, then run grepai watch to rebuild the vector and symbol indexes.
