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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds value by disclosing the three information facets returned (charge, delivery, access), but says nothing about what happens if the find is uncharged or unauthorized, or whether any cost is incurred by reading commerce data.

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?

One front-loaded sentence with no filler, which is the right size for a single-parameter read tool. It loses a point because vague phrasing such as 'who can open it' costs clarity without saving space.

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 one-param read with full annotation coverage and no output schema, the description does enough to convey the general payload, but it omits the identifier semantics and any failure or empty-result behavior. Nothing is dangerously missing, yet an agent still cannot tell exactly what shape of commerce data comes back.

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% and the single parameter 'find_id' carries no description, so the description must compensate and does not. Worse, it calls the entity a 'run' while the parameter is find_id, leaving the agent to guess that a run and a find are the same object.

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 read verb and enumerates three concrete facets of what is returned: charge, delivery, and access. It is identifiable as a read tool, but it never ties itself to the 'find' resource named in the tool and parameter ('find_id'), instead using 'run', and it does not distinguish itself from close siblings like get_delivery or reconcile_find_commerce.

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?

There is no statement of when to use this instead of get_delivery, get_find, or reconcile_find_commerce. The agent is left to infer that this is the commerce/payment angle of a find, and nothing indicates prerequisites such as when billing data only exists after delivery.

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