set_clipboard

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

With no annotations, the description carries the full burden. It states the action but does not explicitly disclose that the clipboard is overwritten, nor does it mention return values or error cases. However, for a simple setter, the implied behavior is clear enough, so this is adequate but not rich.

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 short and front-loaded, with a single sentence for the tool and a compact argument list. However, the 'Args:' section is redundant given the schema already documents the parameter, so it is not maximally concise.

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 simple one-parameter tool with no annotations and an output schema that is not shown, the description is sufficient to understand the core function. It lacks details about output or side effects, but the tool's simplicity keeps the missing information minimal.

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 has 0% description coverage, so the description must compensate. The 'Args:' line repeats the parameter name and essentially rephrases the tool's purpose ('Text to copy to clipboard') without adding meaningful detail beyond the schema's type and title. It provides little additional semantic value.

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 'Copy text to the clipboard' clearly states a specific verb ('Copy') and resource ('clipboard'), and it distinguishes from sibling tools like get_clipboard ('Get') and clear_clipboard ('Clear') by the verb used. This is a clear and specific purpose.

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 such as get_clipboard or clear_clipboard, nor does it mention any prerequisites or exclusions. It simply states the action with no contextual usage advice.

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