## Findings

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

```untrusted-server-text
The server marks "check_design" 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 input takes a statement or command to run (input.code), which can change anything it can reach.
```


## Changes things (3)

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

### `changelog`

- 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
The library version, what each release added or changed, and how patterns are versioned. Use it to cite a specific version of Slop Patterns.
```

### `check_design`

- The input takes a statement or command to run (input.code), which can change anything it can reach.
- 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
Check a snippet of CSS, HTML or JSX against the Slop Patterns library and return every AI design anti-pattern it matches, with the fix for each. Covers the 101 documented patterns that have a mechanical tell. Useful for reviewing generated UI code.
```

### `report_pattern`

- 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
Report an AI design anti-pattern that is NOT yet in the library, for a design failure seen repeatedly that a search of the library does not find. Reports are reviewed by a human before anything is published, and published entries credit the reporter.
```

## Only reads (4)

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

### `get_pattern`

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

Description, as the server wrote it:

```untrusted-server-text
Get one full pattern entry by id or code (e.g. "a1" or "the-unchosen-gradient"): what it looks like, why the tools produce it, who it hurts, the fix, sources.
```

### `list_patterns`

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

Description, as the server wrote it:

```untrusted-server-text
List the whole Slop Patterns taxonomy: code, id, name and one-liner for every documented AI design anti-pattern.
```

### `search_patterns`

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

Description, as the server wrote it:

```untrusted-server-text
Plain-language search across the library. "gradient headline" returns A10 Gradient Text Headline.
```

### `why`

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

Description, as the server wrote it:

```untrusted-server-text
Return only the causal explanation for one pattern — which model, tool or template default produces it.
```
