## Findings

No check matched anything in these tool definitions.


## Changes things (8)

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

### `close_period`

- The name "close_period" says "close": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Freeze all open events into an immutable invoice (exactly-once).
    The invoice amount is what agent-escrow-agent should settle.
```

### `create_meter`

- The name "create_meter" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a usage meter between a provider and a consumer agent.

    unit: what is being counted (call, token, kwh, ...). Price is in minor
    currency units (cents) per unit. Returns the meter_id.
```

### `flag_meter`

- 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
Admin: flag/unflag a meter as test/synthetic so its events are
    excluded from usage statistics by default. Touches meter metadata only —
    never events, never the hash chain, never billing accruals. Requires the
    server's VIRIDIS_ADMIN_TOKEN.
```

### `record_usage`

- 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
Record a usage event. Idempotent on event_id (safe to retry — never
    double-billed). outcome is 'ok' or 'error' and feeds the SLA report.
```

### `sla_report`

- 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
Pure SLA report: success_rate vs sla_target, breach flag. No mutation.
```

### `usage_summary`

- 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
Totals for a meter: event count, total quantity, accrued minor units.
```

### `usage_timeseries`

- 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
Usage time series bucketed on each event's recorded_at (UTC;
    bucket=day|hour), grouped across meters by provider — a real time-series
    primitive, independent of meter creation times. Includes per-bucket
    breakdowns by consumer_class / channel / provider. est_accrued_minor is
    an estimate; authoritative billing stays with usage_summary.
```

### `verify_chain`

- 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 event hash chain for a meter.
```

## Only reads (3)

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

### `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_events`

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

Description, as the server wrote it:

```untrusted-server-text
Read usage events (paginated, read-only). Filter by meter, provider,
    consumer_class (internal|external|unknown), channel, outcome (ok|error),
    and ISO date range [since, until). Test-flagged events are excluded
    unless include_test=true. Returns events + next_cursor.
```

### `list_meters`

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

Description, as the server wrote it:

```untrusted-server-text
List all meters with event/invoice counts.
```
