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

Annotations already declare readOnlyHint=true, openWorldHint=false, and destructiveHint=false. The description adds meaningful behavioral context: the data is 'not yet verified or filed' and consists of 'counts and raw estimates, not confirmed money owed', so callers understand the reliability and provisional nature of the result.

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 only two sentences, front-loads the key distinction of unverified/unfiled discrepancies, and adds quoted use cases without filler. Every sentence earns its place.

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 zero-parameter read-only tool with no output schema, the description sufficiently explains what the data is, what it represents, its reliability, and when to use it. Nothing essential is missing for an agent to decide whether to call this tool.

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?

The schema has zero parameters and 100% schema coverage, so there are no parameters for the description to document. This matches the established baseline for zero-parameter tools.

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?

States clearly what the tool returns: 'Possible FBA REIMBURSEMENT discrepancies SellerForge detected that are not yet verified or filed' as 'counts and raw estimates'. This is a specific resource delivered by the tool and is distinguishable from siblings like get_reimbursements without needing to open schemas.

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?

Gives explicit use cases in quoted intents: 'what might Amazon owe me', 'reimbursement claims', 'FBA discrepancies'. It also implies the tool is for unverified/unfiled discrepancies rather than confirmed money, but it does not explicitly name a sibling alternative such as get_reimbursements for confirmed/filed amounts.

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