C2.7/5.0
Behavior2/5

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

With no annotations, the description carries the full behavioral burden and does little beyond implying a read. It does not say what happens when the Id is not found (error vs. empty), whether pagination or includes/expand options exist, or what permissions are needed to read purchases.

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?

One short, front-loaded sentence with the resource and lookup key up front and no wasted words. Its brevity is efficient, though the same brevity leaves gaps rather than being tight-but-complete.

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

Completeness2/5

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

For a tool with no annotations, no output schema, and a nested params object with additionalProperties allowed, the description is too thin. An agent gets no information about the returned purchase shape or how to handle not-found or permission failures.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate for the single 'id' parameter. "By Id" maps the parameter to its role but gives no format expectations (numeric vs. string, purchase entity ID), and says nothing about the free-form additionalProperties bag in the nested params object.

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

Purpose4/5

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

States a specific verb and resource ("Get a purchase") plus the lookup key (Id) and system (QuickBooks Online), so an agent knows exactly what it retrieves. It does not, however, distinguish itself from closely related siblings such as search_purchases or get_purchase_order.

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

Usage Guidelines2/5

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

There is no guidance on when to use this versus search_purchases (to find a purchase by criteria) or get_purchase_order (a different but adjacent entity). The only implied cue is that an Id is required, which the schema already states.

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