## Findings

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

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

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


## Changes things (3)

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

### `calculate_building_work`

- 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 a user asks the cost of building, extending or renovating a home, remodelling a kitchen/bathroom, refining a budget or costing drawings, even without naming Proper Job. Computes repeatable local-currency estimates using versioned country-specific construction benchmarks, scope and allowance rules, checked measurement conversions and source-cited drawing quantities. Returns an interactive budget card, tax basis, exclusions and a refinementQuestion. After the card, ask that question in one short sentence when present; keep unknown details optional and do not repeat the country checklist. Supported work: GB, US, AU, NZ, IE, DE, FR, ES, CA, JP, IN; exact scope limits are in the schema and market-coverage resource. Do not substitute UK rates or exchange-rate conversions. Read the drawing skill before host-only attachment analysis; send reconciled structured facts in one call. Detailed trade costing is GB-only; other countries still accept drawing quantities. Reuse unchanged results and use the returned price without inventing or narrowing it. Country, language and units are independent. Do not use for property valuations, land-price discovery, account/project lookup, purchases, issued quotes or legal/safety certification.
```

### `calculate_guide_price`

- 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
Calculate the established GB/US Guide Price contract with its required project inputs, when explicitly requested or used with guide comparisons. For the conversational building budget, other countries or drawings, use calculate_building_work. Returns the original guide card and does not read files, save projects or issue quotes.
```

### `compare_guide_scenarios`

- The name "compare_guide_scenarios" says "compare": 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
Compare GB/US Guide Price scenarios when the user explicitly asks to compare alternatives within those existing policies. Returns the original comparison card and deltas. For other countries or drawing-based refinements, use calculate_building_work with each requested scenario. No foreign-rate conversion or saved-project access.
```

## Only reads (1)

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

### `get_estimate_requirements`

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

Description, as the server wrote it:

```untrusted-server-text
Retrieve UK/US input requirements or labelled reference examples when specifically requested. For a project budget, vague cost question or drawings, use calculate_building_work. Reference examples are not the user's project price. No account or drawing-file access.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `proper-job`:

```json

  "permissions": {
    "allow": [
      "mcp__proper-job__get_estimate_requirements"
    ],
    "ask": [
      "mcp__proper-job__calculate_building_work",
      "mcp__proper-job__calculate_guide_price",
      "mcp__proper-job__compare_guide_scenarios"
    ],
    "deny": []
  }
}
