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

No annotations are provided, so the description must carry the behavioral burden. It clearly indicates a read-style retrieval and enumerates the returned content, but it does not disclose behavior for invalid or missing slugs, auth requirements, or error handling. Adequate but not richly 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?

One efficient sentence that front-loads the resource and identifier before listing the returned fields. Every clause adds informational value and there is no filler.

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 one-parameter retrieval tool with no output schema, the description is sufficient: it names the input and fully enumerates what will be returned. No critical element needed to call the tool correctly is missing.

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%: the slug parameter is described with an example ('aventon-aventure-3'). The description only repeats 'by slug' and adds no new format, constraints, or behavioral nuance beyond the schema.

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?

States a specific verb ('get'), resource ('product'), and selection method ('by slug'), then enumerates the returned components: rating, pros/cons, specs, full review text, review URL, and buy link. This clearly distinguishes it from siblings like search_products and compare_products.

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 is only implied: 'for one product by slug' suggests the agent should use this when it already has a slug and needs the full editorial record. However, the description provides no explicit when-to-use guidance or comparison with alternatives such as search_products.

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