## Findings

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

```untrusted-server-text
The server marks "estimate_tax_set_aside" 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 "estimate_tax_set_aside" says "set": a word for a change.
```

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

```untrusted-server-text
The server marks "request_bookkeeper" 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 "request_bookkeeper" says "request": a word for a change.

## Changes things (5)

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

### `about_tommy_accounting`

- 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
Facts about Tommy Accounting: what it is, who it is for, services, qualifications, how requests work, what it does not do, and links. Takes no inputs.
```

### `categorise_expenses`

- 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
Free estimate for UK sole traders. Maps each expense to an HMRC Self Assessment self-employment (SA103F) expense category using simple keyword rules (no AI), with a confidence level, and flags items that are usually not allowable or need care (entertaining, everyday clothing, fines, private use, depreciation, capital items, mixed-use phone/car/home). Totals per category when amounts are given.
```

### `check_vat_mtd_thresholds`

- 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
Free estimate for UK sole traders. Checks annual turnover against the VAT registration threshold (flags "near" within 10%), explains the rolling 12-month and 30-day forward-look rules, and says whether and from when Making Tax Digital for Income Tax applies. Give the optional qualifying income for each tax year for a definite answer; with only turnover it gives an estimate.
```

### `estimate_tax_set_aside`

- The name "estimate_tax_set_aside" says "set": 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
Free estimate for UK sole traders. Estimates Income Tax and Class 4 National Insurance on self-employed profit, the effective rate and a suggested monthly set-aside (total divided by 12), with the band-by-band working and payments on account worked out (including the first 31 January payment for someone in their first year). Supports England/Wales/Northern Ireland and Scotland.
```

### `request_bookkeeper`

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