Read-onlyIdempotent

Calculate gross/net rental yield, income, operating costs and simple payback in OMR. Calculations only. When: Use when an agent needs financial metrics (yield, income, payback) for a single property. Selection: supporting; prefer for simple single-property yield, income and payback arithmetic. Do not use for live Oman market comparables or multi-property portfolio screening. Input is a strict JSON object; see the schema. Price: $0.01 USD per call. No free preview is advertised for this capability. Full execution is paid per call via x402; an unpaid MCP call returns payment instructions.

A3.5/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnly, idempotent, non-destructive, closed-world behavior, so the safety profile is covered. The description adds real value beyond that: 'Calculations only' (no live data fetching), a per-call price, x402 payment flow, and the fact that an unpaid call returns payment instructions instead of results.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The core purpose is front-loaded and the When/Selection/Do-not-use framing is well structured. However, payment details are restated ('$0.01 USD per call' plus 'Full execution is paid per call via x402') and 'No free preview is advertised' is redundant filler that dilutes an otherwise tight definition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need not be explained, and the behavioral/pricing context is complete. The gap is on the input side: a 7-parameter tool at 14% schema coverage with no parameter explanation in the description leaves required and optional field semantics underspecified for an arithmetic tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 14% across 7 parameters, so the burden falls on the description, yet it adds no meaning for propertyValue, annualRent, serviceCharge, vacancyRatePct, maintenanceCost, or otherAnnualCosts. It merely says 'Input is a strict JSON object; see the schema,' which offers no semantic help for the undocumented fields.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb and a concrete set of outputs (gross/net rental yield, income, operating costs, simple payback) and currency (OMR), which clearly identifies the resource. It distinguishes scope from multi-property and market-comparable work, but does not explicitly separate itself from the very similar sibling analyze_oman_property, leaving some name-level ambiguity.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives an explicit 'When' context and a 'Do not use for...' exclusion covering live market comparables and portfolio screening, which is genuine routing guidance. It falls short of a full 5 because the alternative tools (compare_properties, portfolio_screen, analyze_oman_property) are described by category rather than named.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
