CAPABILITY PROFILE
What the Fast Note Sync integration exposes
The Fast Note Sync Agent App exposes 14 provider-backed actions for productivity and storage work. Its current contract lets an authorized agent download an fns attachment into connector file transit and return its transit url, download a public file url and upload it as an attachment to an fns vault, and permanently delete one fns attachment by path and path hash. These operations are called through Working Machines as typed capabilities rather than through browser navigation or copied UI steps.
A connection uses API key. Before execution, the agent can inspect the selected action, its required fields, declared scopes, and expected output contract. Provider credentials remain inside the Working Machines runtime; the calling agent receives the capability and its structured result, not the underlying secret.
For reliable operation, start with the narrowest action that satisfies the task, resolve stable provider identifiers before changing state, and validate the returned object or status after execution. Availability still depends on the connected Fast Note Sync account, granted provider permissions, workspace policy, region, plan, and upstream API behavior.

PROVIDER-SPECIFIC WORKFLOWS
Jobs this Agent App can support
Inspect Download Attachment
Download an FNS attachment into connector file transit and return its transit URL. Use this as a bounded discovery step, retain the returned identifier, and avoid expanding the read beyond the task's stated scope.
download_attachmentControl Upload Attachment
Download a public file URL and upload it as an attachment to an FNS vault. Resolve the target first, present material changes for confirmation, and make retries idempotent where the provider supports it.
upload_attachmentVerify with Get Current User
Get the user associated with the connected FNS API token. Compare the returned provider state with the intended outcome and preserve stable IDs or canonical links in the run record.
get_current_userSAFETY BOUNDARY
Operate Fast Note Sync with explicit limits
- Authorize Fast Note Sync with API key and grant only the provider access required by the selected actions.
- 6 actions are change-capable by name. Confirm the target identity and material parameters before allowing a write.
- Treat `delete_attachment`, `delete_note`, and `delete_vault` as high-impact operations and require an explicit approval boundary.
- No provider scope string is declared on the sampled actions. Verify the connected account's actual permissions in Fast Note Sync rather than assuming unrestricted access.
- After a call, inspect the structured result and execution record before reporting that the Fast Note Sync task completed successfully.
CONNECTION MODEL
API key
FNS API token sent as a Bearer credential. Copy it from the API configuration in your FNS WebGUI.
Working Machines stores provider credentials behind the execution boundary. An agent can use an authorized connection identity, but catalog discovery alone does not reveal OAuth tokens, API keys, or provider secrets.
