## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `revoke_covenant`

- The name "revoke_covenant" says "revoke": a word for removing or ending something.

Description, as the server wrote it:

```untrusted-server-text
Revoke a covenant immediately and terminally. All subsequent checks deny.
```

## Changes things (3)

Creates or changes something that can be changed back. Claude Code: ask.

### `check_act`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Check (and if allowed, record) a proposed act against a covenant.
    Deny-by-default. Idempotent on act_id — retries never double-consume
    budget. Every check lands on the audit chain.
```

### `grant_covenant`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Grant an agent a covenant: an explicit lease of authority. scopes support
    wildcards ('payments.*', '*'); budget_minor is the total spend ceiling in
    minor units; expires_at is ISO-8601. Returns the covenant_id.
```

### `verify_audit`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Verify the tamper-evident audit chain of allowed/denied acts.
```

## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `covenant_status`

- The name "covenant_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Current state, consumed/remaining budget, and check count.
```

### `describe_agent`

- The name "describe_agent" says "describe": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fleet-standard self-description.
```

### `list_covenants`

- The name "list_covenants" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List covenants, optionally filtered by state (ACTIVE|REVOKED|EXPIRED)
    and/or the bound agent.
```
