## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `cpp_self_employed`

- 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
Compute self-employed CPP contributions for a given year: base + enhanced contributions, CPP2 (second ceiling), total payable, and the tax-deduction vs tax-credit split that goes on the T1 (Schedule 8). Quebec residents pay QPP instead — use estimate_self_employed_tax with province QC for QPP.
```

### `estimate_self_employed_tax`

- 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
Estimate a Canadian self-employed (sole proprietor) person's full tax bill: federal tax, provincial tax, CPP/QPP (incl. CPP2/QPP + QPIP for Quebec), total, after-tax income and effective rate. Fully verified provinces: ON, BC, AB, MB, SK, NS, NB, QC. Other provinces/territories return an honest federal+CPP-only partial estimate flagged supported:false.
```

### `gst_hst_registration_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 whether a Canadian small business / freelancer must register for GST/HST under the $30,000 small-supplier tests (single-quarter test and rolling four-quarter test), with the exact mechanics of when to charge and the registration deadline. Set is_rideshare true for taxi/ride-share drivers (they must register from the first fare).
```

### `instalment_plan`

- 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
Determine whether a Canadian individual must pay quarterly income-tax instalments (the $3,000 / $1,800-Quebec net-tax-owing tests) and compute all three CRA payment options (no-calculation, prior-year, current-year) as quarterly schedules with a suggested no-interest choice. Per the CRA's instalment calculation chart, 'net tax owing' EXCLUDES CPP contributions and EI premiums payable — pass those separately as cpp_payable and they are added to the instalment amounts only (chart line 24), never to the threshold test.
```

## Only reads (2)

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

### `get_tax_deadlines`

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

Description, as the server wrote it:

```untrusted-server-text
Upcoming CRA tax deadlines for Canadian freelancers / self-employed individuals (filing, payment, GST/HST, RRSP, quarterly instalments), each on its CRA effective date with the weekend next-business-day rule applied. Also available as a subscribable calendar feed.
```

### `gst_quick_method_compare`

- The name "gst_quick_method_compare" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Compare the GST/HST Quick Method against the regular method for a Canadian small business: eligibility (revenue ceiling + excluded professions), remittance under each method, and which one keeps more money. Annual figures.
```
