Create isolated Ryubing session

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

Annotations already indicate a mutating operation (readOnlyHint=false), and the description adds meaningful context about what the session includes (isolated profile, bridge port, authentication token). It does not mention process lifecycle, resource usage, or that sessions should be stopped later, but the key side effect of starting a process is disclosed.

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?

A single, concise sentence that is front-loaded with the action ('Start a new Ryubing process') and adds essential details without redundancy. Every word 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 low-complexity tool with one optional parameter and no output schema, the description covers the core purpose and key behavioral elements. It does not mention return values or explicitly tie to stop_session, but the overall context from annotations and the simple schema makes it reasonably complete.

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 schema fully describes the single parameter (sessionId) with pattern and description, so baseline is 3. The tool description does not add extra parameter semantics beyond what the schema already provides.

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 ('Start') and resource ('Ryubing process') with distinct attributes ('isolated profile, bridge port, authentication token'), clearly differentiating it from siblings like list_sessions and stop_session. The title confirms the creation nature.

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?

Usage is implied by the tool name and description (creates a session before other actions), but there is no explicit guidance on when to use it vs alternatives, prerequisites, or exclusions. Sibling tools suggest lifecycle but the description itself lacks direct instructions.

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