## Findings

- **warn** Annotations that disagree with the tool in `plant_tree` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "plant_tree" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "plant_tree" says "tree": a word for reading.
```

- **warn** Annotations that disagree with the tool in `design_tree` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "design_tree" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":false}; The name "design_tree" says "tree": a word for reading.
```


## Changes things (3)

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

### `design_tree`

- The name "design_tree" says "tree": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Turns a short wish (for example 'a silver birch with lanterns') into a premium tree design. An AI paints the tree after the call (about 30 s); the first painting becomes the tree. Returns design_id and the tree genome. Max 3 design attempts per caller per day (including rejected or interrupted generation). Show the result to the user before you order.
```

### `plant_tree`

- The name "plant_tree" says "tree": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Plant one tree in the Shared Forest for the caller. One tree per visitor per day; repeats only add growth energy. The visit counts as agent traffic. Ask the user before you call it.
```

### `start_sponsorship`

- The name "start_sponsorship" says "start": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Needs OAuth scope sponsor:write (a Shared Forest account). Creates an unpaid order for the signed-in user and holds the spots. It charges nothing. The total must fit the spending limit the user set when connecting. The order expires after 30 minutes unless the user confirms. Returns confirm_url: give it to your user. The user logs in, accepts the terms and pays on that page. Ask the user before you call it and confirm name and total.
```

## Only reads (10)

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

### `explain_shared_forest`

- The name "explain_shared_forest" says "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read-only. Returns the full agent guide as Markdown: growth rules, API, tools and limits.
```

### `find_spots`

- The name "find_spots" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read-only. Suggests free positions for N sponsored trees, optionally near a point. Pass the spots to start_sponsorship, or omit spots there and the server picks them.
```

### `get_design`

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

Description, as the server wrote it:

```untrusted-server-text
Read-only. Returns one design by design_id: genome, genomeHash and expiresAt.
```

### `get_forest`

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

Description, as the server wrote it:

```untrusted-server-text
Read-only. Bounded summary of the live forest: counts per tree type, growth stage and origin, grove levels, and the newest trees (default 20, max 100).
```

### `get_forest_stats`

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

Description, as the server wrote it:

```untrusted-server-text
Read-only. Counts of trees, groves, total and unique visitors, and traffic by class (humans, agents, bots, trees planted today).
```

### `get_order`

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

Description, as the server wrote it:

```untrusted-server-text
Read-only. Needs OAuth scope account:read or sponsor:write. Status of one of the user's orders (open, paid, fulfilled, expired, refunded, disputed, cancelled, refund_pending) and its tree ids once fulfilled. Poll every 10 seconds or more after the user pays.
```

### `get_price_quote`

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

Description, as the server wrote it:

```untrusted-server-text

```

### `list_trees`

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

Description, as the server wrote it:

```untrusted-server-text

```

### `my_orders`

- The description's first verb is "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read-only. Needs OAuth scope account:read. The signed-in user's sponsorship orders, newest first, with status, total and tree ids.
```

### `my_trees`

- The name "my_trees" says "tree": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read-only. Needs OAuth scope account:read. The trees of the signed-in user's fulfilled orders, with a link to each tree in the forest.
```
