list_accounts

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

No annotations are provided, so the description carries the burden of disclosing behavior. 'List' implies a read-only operation and the description names the returned fields, which covers the core behavior. However, it does not mention pagination behavior, ordering, filtering semantics, or any authentication requirements, leaving key behavioral details undisclosed.

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, front-loaded sentence with no wasted words. It is concise and easy to parse, though it leaves out important parameter context that would make it fully useful.

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 simple list tool with two optional parameters and no output schema or annotations, the description is minimal. It clarifies what is returned but omits parameter semantics and any guidance on search behavior or pagination, so an agent is not fully equipped to use the tool beyond a bare default call.

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 description does not explain the 'limit' or 'search' parameters at all. An agent cannot learn what 'search' matches against or how 'limit' affects results from either the description or the schema field titles, beyond the default values.

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 states a specific verb ('List') and resource ('sender email accounts'), and names the key output attributes (status, warmup status, daily limit). It is clearly distinct from singular get_account and list_emails, though it does not explicitly name any sibling.

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 guidance on when to use list_accounts versus get_account, pause_account, or update_account. The intended comparison context is absent, so an agent must infer usage from the tool name alone.

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