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

With no annotations provided, the description carries the full burden of behavioral disclosure. It clearly describes what the call returns, including the three pick types, pricing fields, URLs, FAQs, and conditional guidance for reviewed collections. It does not mention non-mutation explicitly, but nothing suggests side effects.

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?

The description is dense but purposeful, front-loading the core purpose and then adding useful detail about contents and usage. It is longer than strictly necessary and somewhat run-on, but every clause contributes relevant information.

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 two-parameter lookup tool with no output schema, the description provides enough context to select and invoke it correctly: resource scope, return contents, conditional behavior, slug discovery, locale/currency caveats, and alternative tools. No critical gap remains for correct invocation.

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 description coverage is 100%, so the schema already documents slug and locale. The description reinforces the slug parameter by noting it works for every slug in get_collections and clarifies that this is an English/AUD reference, but it adds only modest semantic value 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?

The description names a specific resource (a collection) and a concrete outcome: retrieving live picks with product, price, URL, FAQs, and optional guidance. It also differentiates itself from siblings by referencing get_collections as the slug source and get_product/get_quote as currency-related alternatives.

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?

It explicitly says when to use the tool ('Use for precise briefs such as...'), how to discover valid slugs ('Discover slugs with get_collections'), and when to prefer alternatives ('use get_product or get_quote for local currency'). This gives an agent clear routing guidance.

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