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

No annotations are provided, so the description carries the full behavioral burden. It discloses the valid outcome categories, which is useful, but says nothing about mutation effects, idempotency, permissions, error behavior, or what happens to an existing checkout outcome.

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 a single compact sentence with no filler, and the critical allowed values are front-loaded. It is appropriately sized for a simple reporting tool.

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?

An output schema exists, so return values need less description, but the definition remains thin for a three-parameter mutation tool with no annotations and no schema descriptions. It omits when to use the tool, what checkout_id identifies, what note is for, and what effect reporting has.

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 0%, so the description must compensate. It usefully enumerates the allowed outcome values even though the schema defines outcome only as a plain string, but it does not explain checkout_id or note, leaving two of three parameters without added meaning.

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 gives a specific verb, 'Report', and a specific resource, 'what happened to a checkout', making the tool's job clear. It also lists valid outcome values, but it does not explicitly distinguish this tool from siblings such as create_checkout or shop_scorecard.

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 this is used after a checkout event, but it gives no explicit guidance on when to call it versus alternatives. It names no exclusions, prerequisites, or sibling tools.

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