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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions the action ('Press keyboard keys') but lacks details on permissions needed, system-level effects, error handling, or whether it simulates key presses vs. actual hardware events. For a tool that interacts with system input, this is a significant gap in 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 front-loaded and efficient, using two sentences that directly convey purpose and usage without redundancy. Every sentence adds value, making it appropriately sized and easy to parse quickly.

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's moderate complexity (system interaction), no annotations, and no output schema, the description is adequate but incomplete. It covers the basic purpose and usage but lacks behavioral details like side effects or error cases, which are important for safe invocation in an automation context.

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, with the 'keys' parameter fully documented in the schema. The description adds minimal value beyond the schema by reinforcing the examples (e.g., Ctrl+C, Alt+Tab), but does not provide additional syntax, format details, or constraints. This meets the baseline for high schema coverage.

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 specific action ('Press keyboard keys') and resource ('including modifiers (Ctrl, Shift, Alt, etc.)'), with explicit examples that distinguish it from sibling tools like bytebot_type_text (typing text) and bytebot_click (mouse actions). It directly answers what the tool does without ambiguity.

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 clear context for when to use this tool ('for keyboard shortcuts like Ctrl+C, Ctrl+V, Alt+Tab'), which implicitly differentiates it from alternatives like bytebot_type_text for typing full text. However, it does not explicitly state when not to use it or name specific sibling tools as alternatives, keeping it from a perfect score.

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