Get an Amazon product

amazon_get_product

Read-onlyIdempotent

One Amazon product by ASIN: title, price and discount, rating, availability, category path, the About-this-item text, spec table, variations and images.

Use when: "tear down this Amazon listing", "what does competitor's product page say", "how is this product priced and rated". Not for: who else sells it and at what price, use amazon_get_sellers. The searches it ranks for, use amazon_get_keywords. Customer reviews: not available for Amazon. Returns: Record. asin, parent_asin, title, url, byline, price, regular_price (the struck-through list price; null with no discount), discount_percent, currency, rating, ratings_count, is_amazon_choice, is_available, categories[] (broadest first), description, specs[] (group, name, value), variation_asins[], images[]. Cost: 2 credits. Cached 1 day. Example: {"asin": "B0B41YH9B6"}

A4.4/5.0

Behavior4/5

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

Annotations already declare readOnly, openWorld, idempotent, and non-destructive behavior. The description adds meaningful context beyond annotations: cost (2 credits), cache duration (1 day), and the limitation that customer reviews are not available for Amazon. It does not cover auth or error behavior, but with annotations the bar is lower and this is useful added context.

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

Conciseness4/5

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

The description is front-loaded with purpose and usage, then returns, cost, and an example. It is well structured, though the detailed 'Returns' list somewhat duplicates the existing output schema, which slightly reduces conciseness.

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

Completeness5/5

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

Given the rich input schema, existing output schema, and annotations, the description is complete: it covers purpose, usage, alternatives, cost, caching, and return-field summary. Nothing an agent needs to call this tool correctly is missing.

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 100%, so all five parameters are already documented in the schema. The description adds only an example ASIN and does not provide additional syntax or format meaning beyond the schema, making the baseline 3 appropriate.

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

Purpose5/5

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

States a specific verb and resource: retrieve one Amazon product by ASIN, and lists the main fields returned. It explicitly distinguishes itself from siblings by naming amazon_get_sellers and amazon_get_keywords for different needs, so an agent can route correctly.

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

Usage Guidelines5/5

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

Provides explicit 'Use when' examples and a 'Not for' section that routes to alternative tools. This gives clear when-to-use and when-not-to-use guidance with named alternatives.

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