A3.7/5.0
Behavior4/5

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

With annotations already declaring mutation and idempotency behavior, the description adds useful context: a 65536-byte request limit, a 5-second execution bound, and that evidence is software/model only. It also outlines the result shape, though it doesn't clarify whether this creates a lasting job or consumes credits.

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

Conciseness5/5

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

The description is organized into Problem, Input, Result, and Limits sections with no wasted words. It is front-loaded and easy to scan.

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?

Given the nested request schema and output schema, the description covers the problem, input payload structure, result summary, and limits. However, it omits that this is likely a job-submission tool with pricing ('max_total_price') and idempotency implications, which are important for correct invocation.

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 0%, so the description must compensate. It explains the contents of the 'request' object (reference, estimators, rules), which helps, but leaves 'schema_version', 'idempotency_key', and 'max_total_price' unexplained. Baseline is lower than 3, but the request payload description brings it up to 3.

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 ('Compare') and resource ('bounded estimator outputs') along with the comparison basis ('supplied reference and objective rules'). It distinguishes itself from sibling estimation tools, though it does not explicitly name alternatives.

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 problem statement implies when to use it, but there is no explicit guidance on when to choose it over alternatives or when not to use it. The limits section provides constraints but not usage direction.

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