## Findings

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

```untrusted-server-text
The server marks "select_palette" 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 name "select_palette" says "select": a word for a change.
```

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

```untrusted-server-text
The server marks "create_palette_board" 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 name "create_palette_board" says "create": a word for a change.
```

- **info** The word "credentials" in `get_palette_board` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credential".

## Changes things (3)

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

### `create_palette_board`

- The name "create_palette_board" says "create": 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
Generate a labeled downloadable SVG board and matching 12-color PNG from a user-confirmed palette, a chosen outfit/event/packing purpose and optional supplied garment colors. Requires the user’s chosen palette; unknown colors request clarification. Computation only; no upload, charge, account record or closet inference.
```

### `score_color_quiz`

- 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 eight explicit user-selected answers to suggest a 12-color starting palette and adjacent option. Uncertain or conflicting preferences prompt clarification. The versioned result is unconfirmed guidance, not a diagnosis. It never overwrites a confirmed palette.
```

### `select_palette`

- The name "select_palette" says "select": 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
Return a portable user-confirmed palette from an explicit season choice. For correction, pass the prior palette reference so source and revision are retained. Confirm only the user’s stated choice. Keep the new reference for later calls; this does not write account or native report data.
```

## Only reads (3)

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

### `compare_colors`

- The name "compare_colors" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Compare up to 12 supplied six-digit hex colors or standard color names with a portable selected palette. Unknown or ambiguous names request hex values. Return the nearest digital swatch with a fixed RGB rule and concise rationale. This does not assess skin, photos, fabrics or garments you own.
```

### `get_palette_board`

- The name "get_palette_board" says "get": a word for reading.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Reconstruct the same SVG, PNG, selected palette and supplied-color comparisons from a complete board reference. Anyone with a reference can read its public palette data. It is not an account credential and cannot retrieve purchased reports. No Tonebook server record is required.
```

### `get_quiz_questions`

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

Description, as the server wrote it:

```untrusted-server-text
Return Tonebook’s eight categorical self-assessment questions. Ask for the user’s own choices; do not infer choices from a photo or conversation history. No account, photo or payment is needed.
```
