A3.8/5.0
Behavior3/5

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

With no annotations provided, the description carries the behavioral disclosure burden. It does disclose a significant trait: the ticket grants view and control access to the user's desktop. However, it does not mention whether generating the ticket creates state, requires special permissions, expires, or has other side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two clear sentences, front-loaded with the primary action and followed by the key result. There is no filler or redundant restating of the tool name, and every sentence contributes useful information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple one-parameter tool with an output schema, the description covers the core action and result well. It is slightly incomplete only because it does not address usage boundaries or side effects, but those are not critical for a straightforward ticket-generation call.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema already documents session_id with 100% coverage, so the description does not need to add much. It provides contextual framing by tying the ticket to a 'user session', but it does not add extra meaning about the parameter's format, constraints, or behavior beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb, 'Generate', and a specific resource, 'Microsoft Remote Assistance ticket for a user session'. It also clarifies the outcome: the ticket lets a help desk technician view and control the desktop session, which clearly differentiates it from sibling session and diagnostic tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The intended use case is implied by the description: generating a remote assistance ticket for an existing session. However, it does not explicitly state when to prefer this over related tools such as get_session or diagnose_session, nor does it mention any exclusions or prerequisites.

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