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

With no annotations, the description carries the disclosure burden. It does disclose the returned content's shape — every option's value on every criterion as a full table — which is the core behavioral trait for a retrieval tool. It adds nothing about edge cases, such as behavior for an unmatched option name, output format, or an explicit read-only statement.

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

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

A single 20-word sentence with zero filler. The core content ('each option's value on every criterion') is front-loaded, followed by the domain context and the clarifying 'full table' tag. Every phrase earns its place.

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

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

For a one-optional-parameter read tool, the description and schema together cover what data is returned and how to filter it. Gaps remain: no guidance on when to prefer this over compare_criteria/compare_options, and no return-format detail despite the absence of an output schema. Adequate but not fully self-sufficient.

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

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

Schema coverage is 100% and the schema's parameter description ('one option's name, else all') fully documents the filtering behavior. The tool description contributes nothing about the option parameter, so the baseline of 3 applies — the schema does the heavy lifting.

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

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

The description specifies the resource precisely: 'each option's value on every criterion' and emphasizes the complete scope with 'the full table.' This implicitly distinguishes it from the sibling tools compare_criteria and compare_options, which presumably return sliced views. It loses a point for having no verb (list/return/show) and reading as a noun phrase describing content rather than an explicit action.

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

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

Usage context is implied rather than stated. The 'full table' framing suggests this is the comprehensive tool versus the narrower compare_criteria/compare_options siblings, but no explicit when-to-use or when-not-to-use guidance is given. An agent must infer the selection logic from sibling names and the em-dash emphasis.

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