Rules

Server first. Writes go to the running Cognee server over HTTP through the wrapper below — the authoritative path in both local and cloud mode.
cognee-cli is a last resort, not an alternative. It is reachable only on a machine holding a cognee source checkout, and in cloud mode the plugin's venv is never built at all. Use it only when the server is genuinely unreachable and that checkout exists. Unsure which mode you are in? ${CLAUDE_PLUGIN_ROOT}/scripts/cognee-doctor.sh --json reports mode, server_url and reachable without importing cognee.
Empty CLI output is never proof that a write landed. Confirm against the server before reporting success.
