estimate_maintenance

Read-onlyIdempotent

Estimate an annual maintenance reserve in OMR from value, age and unit count with explicit optional assumptions. Uncalibrated heuristic, not a survey. When: Use when an agent needs an annual maintenance reserve estimate for a property, not an actual inspection. Selection: specialized; prefer for Use when an agent needs an annual maintenance reserve estimate for a property, not an actual inspection.. Input is a strict JSON object; see the schema. Price: $0.02 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.

TDQS

B3.4/5.0
Behavior4/5

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

Annotations already cover read-only, idempotent, non-destructive behavior, and the description adds substantive context beyond them: that the model is an 'uncalibrated heuristic, not a survey', plus pricing ($0.02/call), no free preview, and x402 payment behavior for unpaid calls. That is genuinely useful pre-invocation context.

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

Conciseness2/5

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

Labeled sections (When/Selection/Price) aid scanning, but the 'Selection' field repeats the 'When' sentence word-for-word, and the paragraph is bloated with payment boilerplate. Real information density is low relative to length.

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 pricing/payment model is covered. What is missing is any guidance on the optional nested 'assumptions' object and how defaults apply, which matters for a tool whose description emphasizes 'explicit optional assumptions'.

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

Parameters3/5

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

Schema description coverage is only 20% across 5 parameters, so the description must compensate. It names value, age and unit count, but says nothing about the nested 'assumptions' object contents (annualRatePct, additionalUnitCost) or confirms the legacy status of annualRent beyond what the schema already notes.

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?

States a specific verb and resource — 'Estimate an annual maintenance reserve in OMR' — and names the driving inputs (value, age, unit count). It also distinguishes the output from a real 'survey'/'inspection'. Points off only because the purpose statement is padded by duplicated surrounding boilerplate.

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

Usage Guidelines3/5

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

The 'When' clause gives a usable trigger ('needs an annual maintenance reserve estimate for a property, not an actual inspection'). However, no alternative sibling is named, and the 'Selection' clause just restates the same sentence verbatim rather than routing the agent away from an alternative tool.

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