cleanshot_all_in_one

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

With no annotations available, the description alone must disclose behavioral traits. It only says 'Launch' without explaining what happens after launching: whether a UI appears, whether a capture is immediately taken, or whether any side effects occur. The optional position/size parameters hint at customizing the capture area, but the overall user-facing behavior remains opaque.

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 sentence that is front-loaded with the core action and includes the optional parameters without waste. Every word earns its place, and it is appropriately brief for a simple launch operation.

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 tool with no annotations and no output schema, the description is under-specified. It does not explain what 'All-In-One mode' entails, how to invoke it, what the user sees, or what the return value might be. Even with only five optional parameters, the lack of context makes the tool hard to use correctly without additional knowledge.

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 descriptions cover all 5 parameters with clear explanations (e.g., 'X coordinate (0,0 is lower left)'). The description adds only a high-level grouping ('position and size'), which is helpful but not substantive. Since schema coverage is 100%, a baseline of 3 is appropriate, and no additional semantic value is needed.

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 a specific verb (Launch) and resource (CleanShot's All-In-One mode), making the primary purpose apparent. However, it does not differentiate this mode from sibling tools like cleanshot_capture_area or cleanshot_capture_fullscreen, and it leaves the exact nature of 'All-In-One mode' undefined, so it falls short of a 5.

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 no guidance on when to use this tool versus alternatives. There is no mention of scenarios, exclusions, or prerequisites, which is especially problematic given the large number of sibling capture tools that could overlap. No context is provided to help an agent decide between them.

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