get_game_screenshot

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

With no annotations provided, the description bears the full burden of behavioral disclosure. It fails to mention side effects (e.g., file creation, overwrite behavior), permissions, format, or whether the screenshot is returned. The single sentence is insufficient for transparency.

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 conveying the core purpose. While it could include more details, it is not verbose and front-loads the primary action, which is good for an agent.

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 simplicity of the tool, the description should at least clarify whether the screenshot is saved or returned, default save behavior if no path is provided, and output format. The absence of this information and no output schema leaves the agent guessing.

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?

Schema description coverage is 100% for the single 'path' parameter, so the baseline is 3. The description adds no additional meaning beyond the schema's 'Custom save path' description, which is adequate but not enhanced.

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 'Take a screenshot of the running game viewport' clearly identifies the action (take screenshot) and the target (running game viewport), distinguishing it from similar tools like 'get_editor_screenshot'. However, it does not mention what happens with the screenshot (e.g., saved to file, returned), which slightly diminishes clarity.

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?

No guidance is provided on when to use this tool versus alternatives like 'take_screenshot_with_context' or 'capture_frames'. The description does not mention any conditions, prerequisites, or exclusions, leaving the agent to infer usage without context.

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