configure_email

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

Without annotations, the description should disclose behavioral traits like idempotency, side effects (e.g., triggering email delivery), or authorization needs. It only states 'Configure' without explaining if it creates, updates, or resets settings.

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 short and to the point, but it sacrifices necessary detail for brevity. It is not overly verbose, but the lack of critical information reduces its effectiveness.

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 the nested input schema and lack of output schema or annotations, the description is insufficient. It does not explain return values, the effect on the system, or confirm the operation's success.

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 tool description does not explain parameters beyond the schema, and schema description coverage is 0%. Although the input schema includes property descriptions, the tool description itself adds no value for parameter semantics.

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 email settings in Metabase, using a specific verb and resource. It distinguishes from siblings like 'clear_email' and 'update_setting' by focusing on SMTP settings.

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, such as updating individual settings via 'update_setting' or clearing email settings via 'clear_email'. The description lacks context about prerequisites or limitations.

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