## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `suggest_origami`

- 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
Use when the user wants ideas for an occasion, a child's age, a difficulty or a time budget. For an origami request, include category: Origami. Omitting category intentionally mixes all paper crafts, including cutting and quilling. Set the matching category whenever the user specifies a craft family or subject. Uses the site's holiday memberships and minimum age guidance. Time filters compare estimates calculated from step count and difficulty, not measured completion times. State that durations are estimates and folding pace varies; never promise a project will be completed within the requested budget. Returns a ranked page of matching public projects with short paper lines, total and nextCursor; request more only when needed.
```

## Only reads (4)

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

### `find_origami`

- The name "find_origami" says "find": a word for reading.
- Tag untrusted-input: The description's first sentence says "browse": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Use when the user wants to browse or find an origami or paper-craft model by name, animal, object, occasion or difficulty. Understands names such as paper plane and cootie catcher. Returns a ranked page of public projects with a short paper line, materials, steps, posters and lesson links. Broad queries favor demand and model quality. Use nextCursor to browse more, never fetch every page at once. For general square-paper preparation, search A4 largest square or Letter square; square-model cards include exact sheet dimensions and the preparation guide. For a named model paper question, use get_origami.
```

### `get_origami`

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

Description, as the server wrote it:

```untrusted-server-text
Use after selecting a model or when the user asks about its paper, size, difficulty, scissors, glue, occasions or age guidance. Pass the model identifier in the argument named slug, even when its value is a returned id. Returns the full public model summary, recommended sheet shape and size, supplied paper type advice, and paper guide links. Square models include how to prepare a square from A4 (210 mm) or Letter (215.9 mm). Also returns links to the interactive 3D lesson and printable PDF diagrams. Model difficulty and flight properties must come from returned facts.
```

### `get_origami_steps`

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

Description, as the server wrote it:

```untrusted-server-text
Use when the user wants to make a selected model or needs a folding instruction explained. Returns every instruction and its existing 2D diagram, including preparation, hard-move parts and the finish note. Follow only these supplied moves and Finish; do not add shaping, puffing, tuning or other folding instructions. The widget has Back and Next; all steps are available. The site adds rotatable 3D playback and printing.
```

### `list_categories`

- The name "list_categories" says "list": a word for reading.
- Tag untrusted-input: The description's first sentence says "browse": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Use when the user wants to know what Origami Tutor teaches or wants to browse a category. Lists public craft hubs and origami subjects with current project counts and page links. Categories contain no individual project facts; retrieve a model before claiming its difficulty, age, materials or instructions.
```
