knowbe4_store_purchases_get

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Get' implies a read operation, but the description doesn't clarify what data fields are returned, any pagination behavior (unlikely for a single item), whether authorization is required, or what happens if the ID doesn't exist. For a single-resource get operation this is minimal disclosure.

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?

A single sentence that states exactly what the tool does with zero waste. Nothing to trim.

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 single-ID get operation with one required parameter fully documented in the schema and no output schema needed, the description is largely adequate. However, without annotations, a bit more detail on what the returned object contains would strengthen it. Still, for its simplicity level, it's close to 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 coverage is 100% — the single parameter purchase_id is described as 'The store purchase ID' in the schema itself. With just one parameter fully documented in the schema, the description doesn't need to add much. The description doesn't add extra semantic detail, but baseline 3-4 is appropriate given full coverage and a single trivial parameter.

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 uses a specific verb ('Get') and specifies the resource ('store purchase by ID'). It's clear it retrieves details about a single purchase. However, it doesn't distinguish from the sibling tool 'know4_store_purchases_list', which is the obvious plural counterpart, though the 'by ID' phrasing and 'specific' imply the singular detail-retrieval nature.

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?

The description implies the tool is for retrieving one specific purchase ('specific store purchase by ID'), which contrasts it with the list tool. However, it doesn't explicitly state when to use this vs. the list sibling or provide any 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.
