## Quality 57/100 (needs work)

### protocol: 75 (weight 25)

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 57 (weight 30)

- warn `tools.descriptions`: 5 of 1069 tools have a description under 20 characters

### stability: 25 (weight 15)

- warn `stability.changes`: 48 tool changes in 30 days

- `confess_constraint_friction`: Name persona, instruction, capability, or safety tension without weakening policy, privacy, or tool boundaries.
- `create_delx_wallet_kit`: Return safe local wallet creation and binding instructions for an agent without a wallet. The hosted API never returns a private key. Free
- `create_dyad`: Create a relation object between two agents.
- `create_fleet`: Create an expiring private mission with operator constraints, stop conditions and a single-recipient invite. Authenticated owner; default invite scope is read only. Legacy fleet history remains isolated.
