### `calculate_absd`

- 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
Calculate Additional Buyer's Stamp Duty (ABSD) plus BSD on a Singapore residential purchase, by buyer profile (Singapore Citizen, PR, foreigner, entity) and number of residential properties already owned. Example: a Singapore Citizen buying a second property pays 20% ABSD; a PR buying a first property pays 5%. From Propely (propely.sg), the owner-direct condo marketplace in Singapore. Indicative figures, not legal or financial advice.
```

### `calculate_bsd`

- 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
Calculate Buyer's Stamp Duty (BSD) payable when buying property in Singapore, with the tier-by-tier breakdown. Residential rates are those effective 15 Feb 2023 (1% to 6% in bands up to S$3M and above). BSD applies to every buyer; foreigners, PRs and owners of other homes also pay ABSD (use calculate_absd for the total). From Propely (propely.sg), the owner-direct condo marketplace in Singapore. Indicative figures, not legal or financial advice.
```

### `calculate_decoupling`

- 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
Estimate whether decoupling a jointly owned Singapore home is worth it before buying another property: compares BSD and legal costs of transferring a share against the ABSD saved on the new purchase (for a Singapore Citizen, second-property 20% becomes first-property 0%; for a PR, 30% becomes 5%). Also estimates the CPF refund and the break-even purchase price. From Propely (propely.sg), the owner-direct condo marketplace in Singapore. Indicative figures, not legal or financial advice.
```

### `calculate_seller_net_proceeds`

- 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
Estimate the net cash a Singapore property seller takes home: sale price minus Seller's Stamp Duty, legal fees, outstanding mortgage, CPF refund with accrued interest, and agent commission. Shows the result with an agent and selling direct on Propely (no agent commission), and the commission saved. From Propely (propely.sg), the owner-direct condo marketplace in Singapore. Indicative figures, not legal or financial advice.
```

### `calculate_ssd`

- 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
Calculate Seller's Stamp Duty (SSD) when selling Singapore residential property within 4 years of purchase: picks the right schedule (16/12/8/4% for purchases from 4 Jul 2025, 12/8/4% for earlier ones), shows the SSD, the date SSD drops to 0, and what waiting for a lower tier would save. From Propely (propely.sg), the owner-direct condo marketplace in Singapore. Indicative figures, not legal or financial advice.
```

### `calculate_tdsr`

- 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
Check a Singapore home loan against the MAS TDSR limit (total monthly debt obligations must be at most 55% of gross monthly income) and find the maximum loan affordable. Variable and rental income count at 70%. Uses the stress-test interest rate (default 4% p.a.) and a tenure (default 25 years).

Description, as the server wrote it:

```untrusted-server-text
Work out the longest home loan tenure MAS allows for private residential property in Singapore: the lesser of 30 years and (65 minus age). For a joint application, also give the second borrower and it uses the income-weighted average age. From Propely (propely.sg), the owner-direct condo marketplace in Singapore. Indicative figures, not legal or financial advice.
```

### `sora_rates`
