## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `estimate_propeller`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Thrust, torque and shaft power for one propeller, from its printed size.

    A closed-form momentum plus blade-element equation — no motor, no battery,
    no account. Give the size as it is printed: a 10x5 is `diameter_in=10`,
    `pitch_in=5`. `chord_ratio` is the chord at 75 % radius over the diameter:
    0.065 thin electric, 0.07 sport, 0.10 slow flyer, 0.11 multirotor.
    
```

### `simulate_powertrain`

- 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
Solve one operating point of a whole powertrain on the Fast model.

    Battery, ESC, motor and propeller are solved together, so the answer is a
    real thrust and current, not a propeller curve. The numbers come back in
    `result` (`result.All` = system totals in SI units: thrust N, current A,
    power W, time s; one entry per rotor; `result.Battery`), with a share URL.
    No second call is needed to read them.
    
```

### `sweep_powertrain`

- 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
Solve a powertrain across a throttle or airspeed range, up to 25 points.

    `sweep.steps` is the NUMBER OF POINTS, not a step size: start 40, stop 100,
    steps 4 gives 40, 60, 80 and 100. One sweep beats a loop of single points.
    The points come back in `result.points` with the share URL; no second call
    is needed to read them.
    
```

## Only reads (4)

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

### `get_component`

- The name "get_component" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read one database row by its id (`comp_…`), with provenance.

    Propeller rows give diameter, pitch, blade count, weight and maximum rpm.
    Blade station geometry is never returned.
    
```

### `get_result`

- The name "get_result" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read a stored result: a share `token` from a run, or a `simulation_id`.

    `simulation_id` needs a ThrustLab API key in `Authorization: Bearer` and
    reads only that account's own runs.
    
```

### `get_validation_summary`

- The name "get_validation_summary" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
How accurate a model is, measured against wind-tunnel and bench data.

    `model` is "fast", "full", or an exact report slug such as "prom-5.3". The
    numbers are error against measured data by partition and channel, with the
    envelope they were measured inside. Quote the model name with the number.
    
```

### `search_components`

- The name "search_components" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find motors, propellers or batteries in the ThrustLab database.

`component_type` is "motor", "propeller" or "battery". `query` is a
case-insensitive substring of the part name or its maker ("APC", "T-Motor",
"13x6.5"). The maker sits under `spec.brand` for motors and batteries and under
`spec.type` for propellers. `limit` is capped at 200 rows a
page; when `has_more` is true, pass the returned `next_offset` as `offset` to
read the next page. Each row carries its datasheet values, its source and the
CC BY 4.0 attribution line. Pass a returned `id` to
`simulate_powertrain`.

```
