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

No annotations provided, so description carries burden. It discloses that it checks synthesized sources and returns supporting/contradicting evidence. However, it does not mention read-only nature, auth needs, or data freshness. Reasonable but not fully transparent.

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?

Single concise sentence front-loads key information (verb, resource, outcomes). Could be slightly more structured but efficient and clear.

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 simple tool with 2 simple parameters and no output schema, the description covers purpose, outcomes, and evidence. Could add nuance like how to interpret results but largely complete.

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 has 0% description coverage; parameters (claim, product_slug) are self-explanatory from names. Description adds no extra syntax or format details. Adequate but minimal enhancement beyond names.

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?

Clearly states the tool checks a claim about a product against GYIBB's synthesized sources, listing possible outcomes (supported, contradicted, mixed, insufficient-data) and noting it returns quoted evidence. Distinguishes itself from siblings like compare_products or get_product_review.

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?

Implies usage when needing to verify a specific claim, but does not explicitly state when to use this tool over alternatives like get_product_review for full context or compare_products for comparisons. No when-not-to-use guidance.

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