## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

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

### `archive`

- The name "archive" says "archive": a word for removing or ending something.

Description, as the server wrote it:

```untrusted-server-text
$1.00. Every case in one response. One payment, no subscription, no account.
```

## Can't be undone (1)

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

### `brief`

- The description says "irreversible".

Description, as the server wrote it:

```untrusted-server-text
$0.05. Pre-flight risk brief before an irreversible action, drawn from the ways that class of action actually failed.
```

## Changes things (6)

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

### `audit`

- 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
$0.02. Full audit of a claim: why each tripped check matters, the incident behind it with measured numbers, and what to run.
```

### `catalog`

- 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
Free, no wallet. What the archive holds, what each paid tool costs, and how payment works.
```

### `contents`

- 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
Free, no wallet. Every case title in the archive, tagged with the trap it illustrates. Titles only, no bodies. Read this to see what the paid archive actually contains before deciding it is worth a dollar.
```

### `precheck`

- 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
Free, no wallet. Check a conclusion against nine known ways of fooling yourself and get back which checks it trips plus the question each one asks. Use it before writing 'we found that'. The paid audit tool adds why each matters, the real incident with the numbers measured at the time, and what to run.
```

### `research`

- 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
$0.25. The 107 measurement failures from an eight-month attempt to measure one person's individuation with embeddings.
```

### `sample`

- 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
Free, no wallet. Two complete post-mortems from the archive.
```

## Only reads (1)

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

### `search`

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

Description, as the server wrote it:

```untrusted-server-text
$0.01. Three real agent post-mortems matching a symptom, each with root cause, the fix that worked, and the prevention rule.
```
