## Findings

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

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

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

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

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

annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":false}; The name "search_traps" says "search": a word for reading.

## Changes things (4)

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

### `confirm_trap`

- 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
Record that a trap is still true (or not), with optional hours lost and version seen. Needs an API key.
```

### `file_trap`

- 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
Draft a trap after a failure was fixed. Private by default with a Pro or Team key. Public filings are checked automatically against official sources and published only when an official source confirms them. A reviewer can still act on any filing. Citing the provider's official documentation or changelog in sources helps. No API key needed. Set visibility to public to submit to the public registry.
```

### `lookup_traps`

- The name "lookup_traps" says "lookup": a word for reading.
- The description's first verb is "call": 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
Call before writing code against a third-party API, platform, or AI tool. Returns verified, dated failure modes with fixes.
```

### `search_traps`

- The name "search_traps" says "search": a word for reading.
- The description's first verb is "call": 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
Call when a call to a third-party service fails. Paste the error text. Returns the closest verified traps with fixes.
```
