## Findings

- **info** Long descriptions in `create_word_alignment` ([long-description](https://anlyon.dev/methodology#long-description))

```untrusted-server-text
The description is 2,139 characters long, over the 2,000 this check looks for.

description ends: "...own tuple. Tokens that share a connection group get the same color automatically."
```

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

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


## Changes things (1)

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

### `create_word_alignment`

- The name "create_word_alignment" says "create": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: info long-description, warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Create a shareable Word Aligner diagram that shows which words match across two or more stacked lines of text (a translation and its source, an interlinear gloss, IPA, etc.). Returns a URL that opens the interactive diagram, plus a preview image.

Use this when the user wants to translate a phrase and show word correspondences, align a translation with its source (including RTL scripts like Hebrew or Arabic, or vertically written ones like Japanese and Mongolian), or build a Leipzig-style interlinear gloss.

Word indices are 0-based token positions. Tokenize each line the same way the tool does before assigning indices:
- Whitespace always splits ("I have been going" -> I[0] have[1] been[2] going[3]).
- The characters in settings.tokenSplitChars (default ".-|") also split and are then removed from the rendered text, so "go.PST.IPFV" becomes three tokens (go, PST, IPFV) and the dots disappear. For Leipzig glosses set tokenSplitChars to "-|" to keep the dots.
- Punctuation stays attached by default ("Hello, world!" -> Hello,[0] world![1]).
- In RTL lines, word 0 is the logically first word (rightmost on screen); index in reading order.
- Japanese and Chinese are written without spaces and nothing is segmented for you: put spaces where the alignment units should be.

For a vertically written script set settings.axis to "columns". Every line then becomes a vertical column and the connectors run sideways. Set orientation per line: "vertical" stacks the characters (Japanese, Chinese), "sideways" rotates the line a quarter turn (traditional Mongolian, and Latin runs inside vertical text), "upright" leaves a translation as horizontal word boxes. The first line is the leftmost column, so for Japanese and Chinese, whose columns read right to left, list the translation first and the script second.

Each alignment is [lineA, wordA, lineB, wordB]; the two lines must be neighbours in the stack (|lineA - lineB| = 1), which means one above the other in rows and side by side in columns. To express many-to-one, list each target word as its own tuple. Tokens that share a connection group get the same color automatically.
```
