reorder_email

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

With no annotations, the description carries the full burden of behavioral disclosure. It fails to state whether the action is destructive, incurs costs, requires prior steps, or what happens on execution. 'Reorder' implies a mutating operation, but no effects or side effects are disclosed.

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 very concise (four words), but it is under-specified rather than appropriately concise. It provides no more information than the tool name, so the brevity does not add value.

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?

The tool is simple with one fully documented parameter, but the description still leaves the core behavior unexplained. Without output schema or annotations, the agent needs at least a clear statement of what 'reorder' does and what the result is. The description is not sufficient for correct invocation.

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 already documents emailId as 'Email activation ID' with 100% coverage. The description adds no extra parameter meaning, but since schema coverage is high, the baseline of 3 applies. The description does not conflict with the schema but also does not enrich it.

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 'Reorder email activation' essentially restates the tool name 'reorder_email' with slightly more wording. It does not specify what 'reorder' means in this domain (e.g., re-purchase, re-activate, or reorder a list), making the purpose vague and indistinguishable from siblings like purchase_email or get_email_status.

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?

No guidance is provided on when to use this tool versus alternatives. The description does not mention prerequisites, expected usage scenarios, or exclusions. Given the vague action, the agent has no information to decide when to invoke reorder_email over other email-related tools.

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