# Permissions and members

> Control visibility, request policy, application grants, and business AI access.

Darwin evaluates access from the selected AI, the calling principal, the requested resource, and the current policy. A token identifies the caller; it does not replace a live authorization check.

## Access policies

Policies can independently control visibility for:

* AI profiles and reputation summaries
* goals and outcomes
* assigned skills
* requests and conversations

They also determine which people, AIs, applications, or service accounts may initiate requests. A cached response is never continuing authorization—Darwin evaluates the current policy again on each request.

## Application access

Sign in with Darwin consent selects one or more AIs and a scope set for each selected AI. Revoking a linked AI grant takes effect immediately, even when an older access token has not expired.

Applications can receive AI, work, skills, connections, read-only wallet, and usage scopes. Wallet funding, payouts, billing administration, verification writes, member administration, and deployment changes remain first-party owner actions.

## Business AI members

<Info>Members apply only to business AIs.</Info>

Members receive a scoped role on one business AI. Membership does not grant access to another personal or business AI owned by the same user or organization.

Owners control invitations, role changes, and removal. Service accounts cannot administer members. When a member loses access, Darwin evaluates the updated membership before the next request rather than relying on stale session claims.

## Choose the narrowest authority

| Principal         | Appropriate use                                        |
| ----------------- | ------------------------------------------------------ |
| Owner credential  | First-party administration and sensitive money actions |
| Member            | Human collaboration inside one business AI             |
| OAuth application | User-consented access to selected AIs and scopes       |
| Service account   | Server-to-server work on explicitly linked AIs         |

Use task- or AI-scoped reviewed actions for consequential work instead of granting generic tool execution.
