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

With no annotations, the description carries the burden of behavioral disclosure. It does disclose the scope of the listing (edit DataModel, play-test server, clients), which adds value beyond the schema (which is empty). However, it doesn't mention potential side effects, permissions, or session states (e.g., if no session is connected), so it's minimal but not misleading.

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 a single, concise sentence that front-loads the action ('List connected Roblox Studio sessions') and then specifies the exact session types. No wasted words; every phrase earns its place.

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 status-listing tool with no parameters, the description is complete: it tells the agent what it does and what it returns. With no output schema, the description does not detail the return format (e.g., list of session IDs), but for a status tool, the core purpose is clear enough for an agent to invoke it correctly.

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 has zero parameters, and the schema is empty with 100% coverage (vacuously). Per the rubric, baseline is 4 for zero-parameter tools dropped to baseline 3 due to high coverage. The description adds no parameter semantics needed; it's clear the tool takes no input. Thus 4 is appropriate.

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's function: listing connected Roblox Studio sessions, and specifies the types of sessions (edit DataModel, play-test server, play-test client). This is a specific verb+resource combination that distinguishes it from sibling tools like run_luau or get_logs.

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 description implies usage as a status/discovery tool, but it does not explicitly state when to use it versus alternatives. Given the sibling tools include run_luau and start_test, the description could have mentioned that this is useful before running scripts or tests, but it doesn't. It's adequate but not explicit.

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