FAQ
Is Engram a vector database?
No. Default Engram search is deterministic lexical search. engram search --semantic adds deterministic local similarity, not embedding-backed semantic search. Graph vectors are local hashed word vectors, not semantic embeddings. Optional local sqlite-vec is an acceleration layer, not the source of truth.
Does Engram write memory automatically?
No. Agents propose candidates; humans approve. Direct terminal CLI uses A/B/C. AI-agent chat uses yes/audit/cancel. Only explicit force requests (ss -f) save every candidate, and agents must not add --force unless the human requested it.
Where does memory live?
- Workspace memory:
<project>/.agents/.engram/ - Global memory: wherever you configure it (default empty until configured)
Workspace memory wins. Global memory is fallback for reusable preferences and team context.
Which agents are supported?
Codex, Claude, Gemini (and Antigravity Gemini-compatible surfaces), Cursor, Windsurf/Cascade, OpenCode, Copilot, Cline, generic AGENTS.md-compatible hosts, MCP-capable hosts, and slash-command hosts. See Agent Integrations overview.
Is encryption implemented?
Encryption config exists, but encrypted storage is not implemented yet. Document current limitations clearly.
Can I use Engram without Git?
Yes. Git is optional but recommended for audit history, portability, and team review.
How do I archive wrong memory?
engram archive --reason "<why>" <id-or-file>
The file leaves active routing only after approval and remains preserved under archive/. Use archive, not delete, for auditability.
How do I move global memory?
engram update-global-folder <new-path>
engram ugf <new-path>
engram move global folder from <old-path> to <new-path>
Add --move-from-path <old-path> when they also want Engram to move the whole old global root into the new location.
Legacy memory migration to schema v3
engram upgrade --latest also migrates active v1/v2 memory files in the workspace and configured global roots to schema v3. Engram preserves each Markdown body exactly, creates <memory-file>.pre-v3.bak, fills only deterministic metadata, refreshes integrity hashes, and rebuilds the index, graph, and eligible vector sidecars. It never invents evidence_refs; a memory without verified trace links is marked evidence_status: unverified. Invalid memories are reported and skipped, archived memories are not rewritten, and a second run is idempotent.
Preview all changes without writing:
engram upgrade --latest --plan
Run only the memory migration, without overwriting linked agent artifacts:
engram upgrade --migrate-memories
Skip memory migration during a latest upgrade:
engram upgrade --latest --no-migrate-memories

Configuration upgrade inventory
After a package update, run engram upgrade --latest --plan before engram upgrade --latest. The shared inventory scans workspace and global Engram-managed memories, instructions, skillsets, configs, hooks, and plugins. User-authored bytes are preserved; ambiguous mixed files are reported as conflicts. See Configuration upgrades.
