Stop managed Ryubing session

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

The description adds behavioral context beyond annotations by clarifying that the process is stopped individually and the profile is retained by default, unless explicitly removed. This complements the destructiveHint=true annotation without contradicting it.

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 two concise sentences. The first states the primary action, and the second adds a crucial caveat about profile retention. No unnecessary words, and it is front-loaded with the main purpose.

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 two-parameter destructive tool, the description is fairly complete. It explains the core action and a key side effect. It lacks details about error conditions or post-stop state, but given the simplicity and annotations, this is acceptable.

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?

With 0% schema description coverage, the description must compensate. It partially does by hinting at the 'removeProfile' parameter ('unless explicitly removed'), but it does not add details about 'sessionId' or clarify parameter syntax. The meaning of sessionId is obvious from the name, but the description could be more explicit.

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 purpose with a specific verb ('Stop') and resource ('one managed Ryubing process'). It distinguishes this from sibling tools like ryubing_create_session or ryubing_launch_game by focusing solely on termination.

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 provides clear context for when to use this tool: to stop a managed session. It also implies usage for the 'removeProfile' behavior by noting the profile is retained unless explicitly removed, but it does not explicitly mention alternatives or when-not-to-use scenarios.

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