open_dialog_window

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

The description indicates a read-only operation (tailing a log), but the annotation readOnlyHint=false contradicts this, suggesting the tool might modify state. No other behavioral traits are disclosed beyond what annotations already provide.

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 concise, front-loaded with the core purpose, and includes necessary details (e.g., the window stays open until closed, like tail -F). Every sentence adds value.

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?

The description is complete for a tool with no parameters and a clear purpose. It explains the output (the log contents) and the behavior of the window, leaving no obvious gaps.

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?

There are no parameters, and the schema coverage is 100%. The description does not need to add parameter information, so a baseline of 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 opens a terminal window that tails the live cross-session signal log. It specifies the purpose (monitor dialog between sessions), the resource (signal log), and distinguishes it from sibling tools that are more about managing or querying data.

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 explains when to use the tool (to see real-time dialog between sessions) but does not provide explicit guidance on when not to use it or mention alternative tools. The context is clear but lacks exclusions.

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