launch_app

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

No annotations are provided, so the description carries the full burden. It discloses that the tool performs 'automatic Tkinter patching' to enable inspection, which is a key behavioral trait. However, it does not mention potential side effects (e.g., closing existing apps, error handling for invalid scripts) or resource usage. Some transparency is present but incomplete.

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 very concise, consisting of two short sentences. The key information (launch app with inspection) is front-loaded, and every sentence provides value. There is no wasted text.

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?

Given the tool has one parameter, no annotations, and an output schema exists, the description adequately covers the essential aspects: launching and enabling inspection. However, it does not mention error conditions or what the output contains (though the output schema covers that). For a launch tool in this suite, it is largely 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 input schema has 100% description coverage, so the schema already describes the single parameter 'script_path' as the path to the Python script. The tool description adds no additional meaning beyond what the schema provides. Baseline score of 3 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 launches a Tkinter application with inspection enabled. It specifies the verb 'launch' and the resource 'Tkinter application', and it distinguishes this tool from sibling tools that interact with an already running application (e.g., click_widget, close_app). The purpose is unambiguous and specific.

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 that this tool should be used first before using other inspection tools, as it states the app will be inspectable once launched. However, it does not explicitly say 'use this before other tools' or provide guidance on when not to use it (e.g., if the app is already running). The context is clear but could be more explicit.

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