## Findings

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

```untrusted-server-text
The server marks "getManual" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

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


## Deletes or cancels (2)

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

### `replyToPrompt`

- The name "replyToPrompt" says "reply": a word for sending, and what is sent cannot be taken back.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Answer the prompt a step is waiting on - do the model work in its `system` and `messages` first. Keep answering until the step is done or failed.
```

### `startStep`

- The name "startStep" says "start": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Start a step - propose, add, documents, ask or remove - in a private store, with its JSON body, as the manual says. propose stores nothing; add stores only facts the person approved, with propose's proposal_id and their reply as confirmation; remove deletes only with confirm true, after the person confirmed. Returns the step's state: `waiting` (a prompt to do and answer with replyToPrompt), `running` (call getStep), `done` (do what `next` says) or `failed`.
```

## Changes things (3)

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

### `ask`

- 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
Ask a question; the store answers only from its facts, each claim linked to its fact, and checks the answer against them. Stores nothing. Returns the step's state: `waiting` (a prompt to do and answer with replyToPrompt), `running` (call getStep), `done` (do what `next` says) or `failed`.
```

### `createStore`

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

Description, as the server wrote it:

```untrusted-server-text
A new, empty FactoGraph store of the person's own: its private link, which these tools take as `store`. Only after the person said yes to having one. Nothing is stored until the link is first opened. The link is the store's key: give it to them once, and never put it anywhere public.
```

### `getManual`

- The name "getManual" says "get": a word for reading.
- The description's first verb is "store": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
The store's manual - how to run its steps and cite its facts - and what it holds: how many facts, from which sources. Read it before the store's other tools, and follow it.
```

## Only reads (2)

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

### `getStep`

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

Description, as the server wrote it:

```untrusted-server-text
Where a running step is now: its next prompt, or its result.
```

### `listFacts`

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

Description, as the server wrote it:

```untrusted-server-text
Every fact in the store, numbered, each number a link to the fact. Cite a fact as its number with its link, [F3](<link>).
```

## Claude Code permissions
