list_myplex_account

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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=true, and destructiveHint=false, fully covering the safety profile. The description adds only the GET endpoint, which is consistent but not deeply behavioral. No contradiction with annotations.

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 lines total, with the purpose sentence front-loaded and the endpoint line adding minor context. Zero fluff; every word earns its place for a tool this simple.

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 zero-parameter read-only fetch with comprehensive annotations and an output schema present, the description is sufficient. The return structure is presumably documented by the output schema, and the safety profile is carried by annotations, so nothing critical is missing.

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 input schema is empty with 0 parameters, so there is nothing for the description to document; the baseline of 4 applies. The description does not add who the returned account belongs to, but with no parameters this is a minor gap.

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 and resource, 'Get MyPlex Account', and the endpoint line 'GET /myplex/account' reinforces it. The resource name helps separate it from generic siblings, but it does not explicitly distinguish it from list_accounts, list_users_account, or list_users_account_json, so it stops short of full differentiation.

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 exists about when to use this tool versus its account-related siblings. Given roughly 300 sibling tools and multiple overlapping account/getter endpoints (list_accounts, list_users_account, list_users_account_json), an agent receives no help selecting among them.

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