email_configure

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

The description mentions fields can be updated individually and unprovided fields retain current value, which is helpful. However, with no annotations, it fails to disclose permissions, potential impact on connections, or error handling. The return of non-sensitive settings is noted but not detailed.

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?

Three sentences efficiently convey the core function, incremental update behavior, and return value. It is front-loaded with the main purpose, with no wasted words.

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?

Given the complexity of nested objects and absence of output schema, the description lacks detail on error conditions, side effects, or the specific format of the returned summary. It is insufficient for an agent to reliably use the tool without additional context.

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 only 33%, and the description does not compensate by explaining individual parameter meanings. It only states that any field can be updated, leaving the agent to infer parameter purpose from the schema, which is incomplete.

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 clearly states the tool configures SMTP/IMAP account settings at runtime with the ability to update individual fields. It uses specific verb and resource, and the purpose is distinct from sibling tools which focus on email operations like sending, listing, or moving messages.

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 explicit guidance on when to use this tool versus alternatives or when not to use it. The context is implied but not stated, missing exclusion criteria or comparative context.

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