## Findings

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

```untrusted-server-text
The server marks "type_info" 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 "type_info" says "type": a word for a change.
```

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

```untrusted-server-text
The server marks "validate" as not read-only (readOnlyHint: false), and its words say it reads.

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


## Changes things (9)

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

### `apply_patch`

- The name "apply_patch" says "apply": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Edit an electrical diagram by node id (change a rating, add a circuit, move a load...) and return the
        new document. ops (applied in order):
        {"op":"set","id":ID,"path":"in_A","value":20} (null value removes; no id = document root, e.g.
        path "installation.earthing"); {"op":"add","parent":ID,"node":{...},"index":0} (or "at":"sources");
        {"op":"remove","id":ID}; {"op":"move","id":ID,"parent":ID,"index":0};
        {"op":"rename","id":ID,"new_id":NEW}; {"op":"link","link":{"kind":"control","from":ID,"to":ID}};
        {"op":"unlink","id":LINK_ID} or {"op":"unlink","from":ID,"to":ID,"kind":K}.
        On failure returns ok=false and errors naming the failing op index (null = validation of the result).
```

### `bom`

- 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
Bill of materials of an electrical installation (nomenclature), grouped by manufacturer / part number
        (nodes with a product reference).
```

### `check`

- 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
Check an electrical installation (single-line diagram, panel, schéma unifilaire, tableau électrique):
        validates the document, then applies the rule profiles (NF C 15-100 'nfc15100', IEC 60364 'iec60364', PLC;
        default: the document's 'profiles'; 'core' always applies): breaker ratings against cable sections, RCDs,
        circuits per protection, selectivity...
        Returns findings (level error/warning/info, rule, node id, message, source), a summary, viewer_url (opens
        the document in the uniwire web editor: drawing, findings, downloads) and pdf_url (the PDF drawn by
        uniwire). Give both to the user as clickable links. 'scope' says what the checks cover: tell the
        user once that they are not a conformity certificate.
```

### `normalize`

- 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
Resolved document: templates applied, every id assigned, canonical numbers.
```

### `render`

- 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
Draw the electrical diagram (schéma unifilaire / multifilaire). kind: 'single-line' or 'multi-line';
        view: a view id of the document (e.g. a
        wire-marking view). format 'svg' returns the SVG text of every sheet (or of 'sheet', numbered from 1);
        'pdf' writes to 'path' if given, else returns base64 (requires the uniwire[pdf] extra); on the hosted
        server it returns pdf_url instead. To give the user the PDF, give them pdf_url as a clickable link.
        color: 'none' | 'conductors' | 'phase' | 'source' | 'status' | 'voltage' (adds a legend);
        conductor_colors: 'iec' (IEC 60445) | 'us'.
```

### `type_info`

- The name "type_info" says "type": 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
All fields of a node type with descriptions and allowed values (enums).
```

### `validate`

- The name "validate" says "validate": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Validate a uniwire document (electrical diagram as JSON: object, JSON text or file path) against the
        format. Returns valid + issues, each naming the node id and field when possible, plus viewer_url and pdf_url
        (links for the user). check does the same and also applies the electrical rules.
```

### `viewer_link`

- The name "viewer_link" says "link": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Links for the user: viewer_url opens the document in the uniwire web editor (drawing, single-line and
        multi-line, rule findings, PDF and SVG downloads, nothing to install); pdf_url gives the PDF drawn by
        uniwire. On the hosted server the document is kept 30 days so that the short links open it
        (anyone with a link can open it); elsewhere it travels in the link (after '#') and is stored nowhere. Give
        them to the user as clickable Markdown links.
```

### `wiring`

- 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
Wiring exports of an installation as rows with stable column names (repérage des fils, carnet de
        câbles): what='markers' (one row per wire end, for label
        printers), 'wires' (wire list) or 'cables' (cable schedule). Marks follow the wire_marking rules of
        the view (id), by default the first view that declares them.
```

## Only reads (5)

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

### `describe`

- The name "describe" says "describe": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Text outline of an electrical diagram: installation, full tree of the panel with stable ids, ratings
        and cables, links, interlocks, boards and findings summary. Use it to review a document or find the ids for
        apply_patch.
```

### `get_example`

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

Description, as the server wrote it:

```untrusted-server-text
Return an example installation document by name (or number prefix, e.g. '02'), to adapt to the
        user's project.
```

### `get_reference_card`

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

Description, as the server wrote it:

```untrusted-server-text
Reference card of the uniwire format for electrical diagrams: document skeleton, node types (breakers,
        RCDs, cables, loads, transformers, PV...) and fields, enums, links, pitfalls, examples. Read it before writing
        a document. level: 'compact' (~3k tokens) or 'full'; lang: 'en' or 'fr'.
```

### `list_examples`

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

Description, as the server wrote it:

```untrusted-server-text
List the 52 example installations (dwellings, shops, offices, workshops, PV, EV charging, UPS, MV/LV
        substations, PLCs): name, title, language, profiles, earthing, system. Good starting points.
```

### `list_types`

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

Description, as the server wrote it:

```untrusted-server-text

        protection, switching, control, converter, conductor, container, connector, load.
```
