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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions the 'single round trip' behavior, which is useful, and details the step structure. However, it does not disclose potential gaps (e.g., partial execution on failure), error behavior, or how it interacts with other input tools. The information is adequate but not comprehensive.

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 well-organized: it starts with a one-line purpose, then defines the step format, gives a usage context, and ends with a concrete example. It is not overly verbose, and the example is efficient and illustrative, earning its place. The front-loading of purpose is effective.

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 4 parameters and no output schema, the description is incomplete. It explains 'steps' thoroughly but omits the purpose and behavior of 'observe', 'show_ui', and 'max_size'. It also does not describe what the tool returns or how the sequence result is delivered. This leaves agents uncertain about side effects and required configurations, making the description insufficient for correct invocation in many scenarios.

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 description explains the 'steps' parameter in detail, including the exact JSON structure for each step and an example. However, the schema coverage is 0%, and the description fails to document the other three parameters (observe, show_ui, max_size). It compensates partially but leaves significant gaps, especially for optional parameters that affect the round trip.

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 runs 'several pad states back to back in a single round trip' and provides a concrete example of a three-hit combo. It distinguishes itself from sibling tools like game_pad by emphasizing sequence and timing, making its purpose unambiguous.

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 explicitly recommends using the tool 'for combos and for anything where the timing between inputs matters more than looking in between,' providing clear context for when it is appropriate. It implies that for cases requiring observation between inputs, one would use separate calls, though it does not explicitly name the alternative.

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