v1.0.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly/idempotent/non-destructive, so the baseline is covered; the description still adds real value by disclosing that polling is credit-free and by giving security guidance (treat marketplace text as untrusted) and output-handling guidance (preserve warnings). It does not disclose what terminal states or fields the response contains.
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?
Three compact sentences, front-loaded with the core purpose, with no filler. Each sentence carries distinct information: purpose, cost behavior, and safety guidance.
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?
With no output schema, the description never says what a status check returns (states, progress, warnings placement), nor how this relates to fetching results afterward. Safety and cost context are complete; response-shape context is missing for a polling tool.
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?
There is a single parameter with 100% schema description coverage ('Customer-owned public job ID'), so the schema does the work. The description only echoes 'customer-owned' and adds no provenance detail such as where to obtain the jobId.
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 and resource ('Check a customer-owned extraction job'), and the title adds that it is a status check. However, it never distinguishes itself from the closest sibling, amz_get_scrape_result, so an agent must infer that this returns job state rather than the extracted data.
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?
'Polling does not consume credits' implies the tool is meant to be polled repeatedly, which is useful usage context. But there is no explicit when-to-use versus amz_get_scrape_result, no statement of when to stop polling, and no prerequisite that jobId comes from amz_create_scrape.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
