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

No annotations are provided, so the description must carry the full burden. The description fails to disclose behavioral traits: it doesn't state whether this is a read-only or mutation operation, what permissions are needed, how results are returned (e.g., sorted, limited), or any side effects. The '[WIP]' tag suggests incompleteness but doesn't add useful behavioral context.

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 brief (one line) but not effectively structured. It's front-loaded with '[WIP]' which adds noise, and the content is under-specified rather than concise. While it avoids verbosity, it fails to convey essential information efficiently, making it more incomplete than truly concise.

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 implied by the tool name (ranking computers by session count), lack of annotations, 0% schema coverage, no output schema, and rich sibling tools, the description is severely incomplete. It doesn't explain the tool's behavior, parameters, output, or how it fits into the broader context, leaving critical gaps for an AI agent.

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 has 1 parameter ('domain') with 0% description coverage, meaning the schema provides no semantic information. The description adds no parameter semantics—it doesn't explain what 'domain' is, its format, or how it relates to the tool's purpose. With low schema coverage and no compensation in the description, this is inadequate.

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 '[WIP] Computers with Most Sessions [Required: sessions]' is vague and tautological. 'Computers with Most Sessions' restates the tool name without specifying what action the tool performs (e.g., list, find, analyze). The '[Required: sessions]' adds some context but doesn't clarify the verb or resource scope. It doesn't distinguish from siblings like 'list_all_user_sessions' or 'users_with_most_sessions'.

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. The '[Required: sessions]' implies a prerequisite but doesn't explain what 'sessions' refers to or how it differs from similar tools (e.g., 'list_all_user_sessions' lists sessions, while this tool focuses on computers with the most sessions). No context on exclusions or alternatives is provided.

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