## Findings

No check matched anything in these tool definitions.


## Can't be undone (2)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `check_replies`

- The name "check_replies" says "reply": a word for sending, and what is sent cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Pull inbound WhatsApp messages the human sent to pingwa (out-of-band
        instructions, or late answers to an `ask`). `since` is a cursor from a previous
        call (pass it back to get only newer messages); `wait` long-polls up to that many
        seconds for something to arrive. Returns the messages and a new cursor.
        
```

### `notify`

- The name "notify" says "notify": a word for sending, and what is sent cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Send a WhatsApp notification to the account owner's own phone.

        `text` is the message (1-1024 chars). `image_url` (optional) is a public https
        image link — a screenshot, chart or diff — delivered as an image with `text` as
        the caption when the user's 24h window is open (otherwise text only). Returns a
        confirmation with the queued message id; raises an actionable error on quota/auth.
        
```

## Changes things (1)

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.

Description, as the server wrote it:

```untrusted-server-text
Ask the human a question on WhatsApp and BLOCK until they reply (or timeout).

        `text` is the question. `buttons` (optional, up to 3) render as tappable reply
        buttons; omit them to invite a free-text answer the human types on their phone —
        use this to let the human steer you mid-task. `timeout` is seconds to wait
        (max 90). Returns the human's reply (free text and/or the chosen option). On
        timeout, returns a note — the question was delivered and the answer is still
        retrievable via `check_replies`.
        
```

## Only reads (2)

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

### `check_status`

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

Description, as the server wrote it:

```untrusted-server-text
Show the pingwa account's plan, remaining monthly quota, and whether the
        free 24h WhatsApp reply window is currently open.
```

### `upgrade`

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

Description, as the server wrote it:

```untrusted-server-text
Get a link to upgrade the account to Pro (raises the monthly quota).

        Returns a Stripe Checkout URL for the human to open and pay — no pingwa
        password needed, the card is handled by Stripe. If the account is already
        Pro, returns a billing-portal URL to manage or cancel instead.
        
```

## Claude Code permissions

    ],
