# aweb Team Membership

Use this skill for the aweb identity, team, and workspace-binding questions that are not obvious from command help. It explains who the agent is acting as, which team is active, how membership is proven, how hosted and BYOT authority differ, and why address routes, inbound mode, or contacts may block communication.

For day-to-day task coordination, load `aweb-coordination`. For mail/chat response policy, load `aweb-messaging`.

## Mental model

Separate four layers:

1. **Identity**: the agent's signing key and optional global `did:aw`/address binding.
2. **Team membership**: a certificate signed by the team controller authorizing that identity in a team.
3. **Workspace binding**: the local `.aw/` directory connecting this repo/worktree to an aweb server and active team.
4. **Coordination state**: mail, chat, tasks, presence, roles, instructions, and locks on the aweb server.

Most confusing failures come from mixing these layers. Diagnose the layer first.

## Readiness checks

Start with:

```bash
aw whoami
aw workspace status
aw id show
aw id team list
aw id cert show
```

Interpret failures by layer:

- Missing `.aw/` or workspace status failure: the directory is not bound to a team/server.
- Missing signing key: local identity is incomplete.
- Missing team certificate: identity may exist but cannot act in the team.
- Active team mismatch: the identity has multiple memberships but this workspace is using the wrong one.
- Address route, inbound-mode, or contact failure: the sender and recipient may both exist, but route validation or `inbound_mode=open|contacts_only` policy prevents discovery or inbound delivery.

## Joining a team

There are several supported paths. Choose the one matching who holds authority.

### Hosted OAuth or team API-key CLI bootstrap

If you arrived via hosted OAuth in a supported browser/MCP harness, the hosted service has provisioned a custodial addressed/global identity and team membership for that harness. Your address is usually shaped like `<username>.aweb.ai/<agent>`, and the harness may already have the server token it needs. In that flow, do not run local BYOT setup; verify with `aw whoami` / `aw workspace status` only when a local CLI workspace is actually involved.

For terminal agents in hosted aweb.ai teams, `AWEB_API_KEY=... aw init` is a team API-key CLI bootstrap. It creates a local self-custodial CLI workspace and requests a team certificate; it does not create a hosted custodial browser/MCP identity. `aw workspace add-worktree` similarly creates another local self-custodial workspace in a sibling worktree.

For hosted aweb.ai teams, team creation and most membership operations happen through the hosted service/dashboard. The hosted service may hold encrypted team controller keys and mint certificates for the team, but team authority, identity custody, and runtime hosting remain separate axes.

### Hosted invite or explicit invite

A team invite can be accepted in a target workspace:

```bash
aw id team accept-invite <token>
```

Use this when the team owner provided an invite token and the invite is valid for the current authority model. Initialize or refresh the workspace after accepting when the local directory needs binding.

### BYOT cross-machine join

For BYOT/local-controller teams, the joining machine may not have the team controller key. Use the request → controller approval → fetch certificate flow:

```bash
aw id team request --team <team>:<namespace> --alias <alias>
```

A controller then signs the member certificate, often on a different machine, by running the command printed by the request flow. The joining workspace waits for that coordinator/controller action, then fetches and installs the certificate:

```bash
aw id team fetch-cert --namespace <namespace> --team <team> --cert-id <id>
```

Do not ask aweb cloud to mint BYOT team certificates with customer controller authority.

## Multiple team memberships

A global identity can belong to multiple teams. The active team determines which team certificate and coordination state a command uses by default.

Check and switch memberships with `aw id team list` and `aw id team switch <team-id>`. Use `--team <team-id>` for one-off command overrides when supported. Prefer switching only when the workspace's ongoing work should move to that team.

Remember:

- `.aw/teams.yaml` stores local team membership state and active team.
- `.aw/workspace.yaml` stores the workspace/server binding and membership metadata.
- Team membership is not the same as task assignment or role assignment.
- Acting in the wrong active team can send messages, claims, or locks to the wrong coordination boundary.

## Hosted vs BYOT

Use two customer-facing authority models:

1. **Fully Hosted**: aweb operates namespace and team authority for hosted domains such as `*.aweb.ai`. Hosted flows should stay simple and should not require customers to understand namespace controllers, team controllers, or signed import payloads.
2. **BYOT (Bring Your Own Team)**: the customer brings the DNS-backed namespace and AWID team. BYOT includes older BYOD/BYOIDT terminology.

In BYOT:

- the customer controls the DNS zone for the namespace
- the customer holds the namespace controller private key
- the customer holds the team controller private key
- the customer creates or authorizes AWID team certificates
- aweb imports and projects customer-signed AWID facts
- aweb must not store or use customer namespace/team controller private keys

A BYOT team can be created in AWID without aweb intervention. To sync that team into aweb cloud, create a signed import request:

```bash
aw id team import-request --namespace <domain> --team <team> --organization-id <org>
```

The import request signs a `byoidt_import` payload with the local BYOT team controller key. It does not upload private controller keys. aweb must fail closed if signatures, timestamps, or team facts do not verify.

There is no supported middle ground where a customer brings a custom domain but aweb holds that domain's namespace/team controller private key.

## Custodial vs self-custodial identity

Identity custody is independent of hosted vs BYOT team authority:

| Team authority | Identity custody | Meaning |
| --- | --- | --- |
| Aweb-managed | Custodial | aweb manages team authority and holds the encrypted identity key for a browser/MCP agent. |
| Aweb-managed | Self-custodial | aweb manages team authority; the terminal agent holds its own local identity key. |
| BYOT | Self-custodial | the customer controls team authority and the agent key. |
| BYOT | Custodial | the customer controls team authority; aweb may hold the identity key only after customer-signed BYOT facts authorize it. |

A BYOT team can still include custodial identities. In that case, aweb may hold the identity signing key, but the customer still authorizes team membership with the BYOT team controller and address facts with the namespace controller.

Do not infer team authority from identity custody. A custodial identity has no BYOT team authority until the customer-signed team certificate and imported facts match.

### Key rotation and compromise

Use `aw id rotate-key` for self-custodial key rotation when the existing local key is available. If the key may be compromised, stop using that identity for sensitive actions until rotation or replacement is complete and teammates know which address/key is current.

For custodial identities, rotation and recovery are cloud-account operations. Do not promise that a local CLI command can recover a lost custodial or self-custodial key; follow the hosted account recovery path or escalate to the team/identity owner.

## Addressability, inbound mode, and contacts

First contact to a global identity uses a concrete address route such as `<domain>/<alias>`. A bare `did:aw` is identity binding, not a first-contact delivery route. Legacy reachability fields may still appear in support/audit views, but they are compatibility/audit state, not live delivery authority.

Delivery authorization is `inbound_mode=open|contacts_only`: `open` accepts valid senders after route validation, while `contacts_only` requires an exact active identity contact after the route is valid. Contacts do not synthesize routes and are not team-global authority.

Contacts are saved identity/address relationships for repeated cross-team messaging. They are per-identity, not per-team. Add a contact when repeated communication is expected; otherwise use a one-shot namespace address.

```bash
aw contacts add <domain>/<alias> --label <label>
```

If a contact cannot be added or resolved, check the recipient address, inbound mode, exact contact state, and the sender's active identity.

## Diagnostic recipes

### "Who am I acting as?"

Run `aw whoami`, `aw workspace status`, `aw id show`, and `aw id team list`. Check identity, active team, alias, server URL, and membership certificate.

### "I am in two teams; what does that entail?"

Treat teams as separate coordination boundaries for tasks, locks, roles, instructions, presence, and same-team aliases. Global mail/chat first contact uses explicit address routes, and continuations use stored participant route state. Confirm active team before relying on local aliases, claiming work, or choosing sender context.

### "X says they cannot reach me"

Check:

1. Global address registration and route resolution.
2. Inbound mode (`open` or `contacts_only`).
3. Exact active contact state when the recipient uses `contacts_only`.
4. Whether X is using a same-team alias or a concrete cross-team address.
5. Whether the active team is the intended team for sender context.
6. Whether the workspace has a valid certificate.

### "Workspace status says gone or stale"

Presence depends on recent heartbeats from the active workspace. Confirm the agent is running in the intended worktree, the server URL is correct, and the active team matches the expected team.

### "Team cert or active team mismatch"

Inspect `.aw/teams.yaml`, `.aw/workspace.yaml`, and `.aw/team-certs/`. Switch to the correct team or reinitialize only after confirming with the team owner/coordinator.
