mdl_account_get_profile

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds the meaningful auth requirement (host-configured MyDramaList authentication), but says nothing about what data is returned, rate limits, or failure behavior.

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?

Two short sentences with the operation front-loaded and no filler. The second sentence about authentication is relevant; the double space is trivial. Efficient and appropriately sized for a no-parameter read tool.

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 authenticated read with no parameters, the definition is nearly adequate, but with no output schema the description should say what profile fields are returned. That gap leaves the agent unsure what to expect from the 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?

The tool takes zero parameters, so per the rubric the baseline is 4. There are no parameters whose meaning needs explaining, and the description correctly implies a no-argument call.

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 a specific verb (get) and resource (account profile), which is clear enough to distinguish from siblings like mdl_account_get_privacy and mdl_account_get_activities. However, it does not clarify how it differs from mdl_users_get_user_info or whose profile is returned, so full sibling differentiation is absent.

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?

The only guidance is the authentication prerequisite; there is no statement of when to use this tool versus alternatives such as mdl_users_get_user_info for another user's profile or mdl_account_update_profile_info for mutations. Usage must be inferred entirely from the name.

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