CAPABILITY PROFILE
What the Nusii Proposals integration exposes
The Nusii Proposals Agent App exposes 14 provider-backed actions for productivity and communication work. Its current contract lets an authorized agent get the nusii account associated with the connected api token, create a client in the connected nusii account, and archive a nusii proposal by id. 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 Nusii Proposals account, granted provider permissions, workspace policy, region, plan, and upstream API behavior.

PROVIDER-SPECIFIC WORKFLOWS
Jobs this Agent App can support
Inspect Get Account
Get the Nusii account associated with the connected API token. Use this as a bounded discovery step, retain the returned identifier, and avoid expanding the read beyond the task's stated scope.
get_accountControl Create Client
Create a client in the connected Nusii account. Resolve the target first, present material changes for confirmation, and make retries idempotent where the provider supports it.
create_clientVerify with Get Client
Get one Nusii client by ID. Compare the returned provider state with the intended outcome and preserve stable IDs or canonical links in the run record.
get_clientSAFETY BOUNDARY
Operate Nusii Proposals with explicit limits
- Authorize Nusii Proposals with API key and grant only the provider access required by the selected actions.
- 5 actions are change-capable by name. Confirm the target identity and material parameters before allowing a write.
- Treat `archive_proposal` 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 Nusii Proposals rather than assuming unrestricted access.
- After a call, inspect the structured result and execution record before reporting that the Nusii Proposals task completed successfully.
CONNECTION MODEL
API key
Nusii API token sent in the Authorization header. Create or view tokens in Nusii Settings > API: https://app.nusii.com/settings/api.
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.
