Keep the existing + web/session-control access restrictions, and exclude callback query strings from proxy logs. +4. Restart Bell and start a new conversation. Ask **"Connect my Notion account."** Open the + private consent link, select your personal workspace, and return to the conversation. + Bell registers the OAuth client automatically; no manually created Notion API token or + client credentials are required. + +Configuration and database connections load only when Notion is used. Keep +`NOTION_ENABLED=false` to leave the integration disabled. + +## Use personal memory + +Bell uses the [personal memory skill](../agent/skills/notion-memory/SKILL.md) to recall +preferences, routines, plans, decisions, notes, and prior activity before relevant tasks. +When connected to the chosen private destination, it saves useful context and verified +outcomes by default, updates existing records, and reads back writes before reporting success. + +- **"Remember that I prefer aisle seats."** Save a preference in the existing memory destination. +- **"Which airline seat do I prefer?"** Recall it in a new conversation. +- **"I prefer window seats now."** Update the existing preference. +- **"Forget my seat preference."** Remove accessible copies within that scope and report any limits. + +Bell reads Notion's MCP memory guidance and reuses the existing personal destinations and +schemas. If a destination is missing, it asks where to save. Creating a new database, +reorganizing content, sharing information, or scheduling work requires approval. + +Detailed notes and activity records use the chosen Notion locations, with concise references +in memory when useful. Plans, attempted actions, and confirmed outcomes stay distinct. +Purchase records may include products, merchant, actual amount/currency, dates and status; +[Link's purchase guide](link.md#personal-purchase-history) covers that workflow. + +The current request, corrections, exclusions, and forget requests take priority over old +notes. Credentials, payment tokens, private checkout fields, and raw transcripts are not +saved. Sensitive personal information needs an explicit memory request or consent. +Free-plan restrictions are reported rather than interpreted as empty results. + +## Persistence and recovery + +Bell is for one person. Limit the Linq sender allowlist to the operator's own phone numbers. +The web operator and each verified Linq identity authorize separately, as with Link. Choose +the same Notion account and destination to share personal memory across those conversations. +A grant cannot be selected through a model-supplied identity. + +OAuth clients, tokens, PKCE verifiers, and pending callbacks are encrypted with AES-256-GCM +and bound to their owner. PostgreSQL session locks serialize refresh, reconnect, and disconnect +across workers. Lost single-use exchange/refresh responses require fresh consent rather than +retrying a possibly consumed credential. Old grants are revoked before replacement consent; +a changed public origin registers a client for the new callback. + +Use `notion_status` to inspect the stored grant. A connected status does not verify remote +access or a saved memory. Use `notion_disconnect` to block access and revoke the grant. +If revocation fails, encrypted tokens remain for retry and access stays blocked. Retry +disconnect to finish. Notion content is unaffected. + +Disabling the integration does not revoke or erase a stored grant. Disconnect before +disabling to revoke access too. If the encryption key is lost, revoke Bell in Notion and +remove the unreadable connection row before reconnecting. + +Bell checks the stored grant before each remote tool call, including when Eve caches a +bearer within a step. Already dispatched requests may finish after disconnect. Schema changes +and deletions have runtime approval gates; ordinary writes use the user's Notion permissions +and memory instructions. If a write fails, Bell reports the unsaved record separately from +the original task outcome and does not repeat the action. + +Memory is saved during conversations. There is no background account sync or guaranteed +logging after a process crash, and a saved deadline is not a scheduled reminder. + +## Verify + +`pnpm check` runs tests, TypeScript, lint, and the production build. Set +`TEST_NOTION_DATABASE_URL` to a disposable PostgreSQL database to include storage tests. +CI's `TEST_LINK_DATABASE_URL` is also supported. The suite creates and drops a unique +schema and never calls Notion or uses application credentials. + +For a live check, connect Notion, save a test preference, and open its returned Notion link +to inspect the content. Start a new conversation and recall the preference, then correct +and forget it. Confirm each write by reading the result. This requires the configured +database, model credentials, and Notion consent; offline checks do not establish live recall. diff --git a/docs/repository.md b/docs/repository.md index f77d120..9de11b7 100644 --- a/docs/repository.md +++ b/docs/repository.md @@ -29,6 +29,7 @@ lifecycle; channel callbacks also handle terminal-session cleanup.
