## Findings

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

```untrusted-server-text
The server marks "generate_rent_ledger" 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 "generate_rent_ledger" says "generate": a word for a change.
```


## Changes things (2)

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

### `calculate_prorated_rent`

- 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 this when the user wants prorated rent for a move-in or move-out (prorated rent calculator, 'tenant moved in on the 17th, how much rent do they owe', partial month rent). Returns the amount, computed to the cent, by three methods side by side (actual days in the month, 30-day month, 365-day year), the daily rate, and the formula, counting the move-in and move-out days inclusively; leap-year February is handled. Assumes rent covers calendar months (due on the 1st). Does not build a full ledger (use generate_rent_ledger for payments and balances) and does not give legal advice.
```

### `generate_rent_ledger`

- The name "generate_rent_ledger" says "generate": 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
Use this when the user wants a rent ledger, tenant ledger, rent ledger template filled in, or proof of rent payments for a tenant: 'make a ledger of my tenant payments this year', 'tenant paid 800 of 1200 rent, what is the balance', amount due as of a date. Takes lease terms (rent, start, due day, late fee rule with grace period) and payments typed or from an attached CSV/Excel file; charges rent monthly with prorated first/last months, applies payments oldest first, adds late fees (flat, percent, daily with cap), carries overpayments forward as credit, and returns a running balance plus PDF statement, Excel and CSV downloads. Does not check state late-fee limits, give legal advice, collect rent, or make rent receipts for proof of address.
```
