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

With no annotations, the description carries the full burden of behavioral disclosure. It discloses the output contents, including the somewhat unexpected provenance banner, and implies this is an introspection/read step. It does not explicitly state that it is non-destructive or describe side effects, but for a schema-inspection tool the behavior is reasonably transparent.

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 two concise sentences: the first lists the output components, the second states the usage directive. Every word adds value, and the key guidance 'call this first' is front-loaded near the end but clearly emphasized.

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 zero-parameter schema-introspection tool, the description covers the return payload adequately and provides the essential usage context. With no output schema, listing columns, numeric flags, row count, and provenance banner gives the agent enough to know what will come back. It could be slightly more explicit about side-effect-free behavior, but the context is otherwise complete.

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 tool takes zero parameters, so parameter semantics are inherently simple. The description correctly focuses on what will be returned rather than parameter details, and there is nothing missing for calling this tool correctly.

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 identifies what the tool returns: columns, numeric indicators, row count, and provenance banner, and frames it as the way to learn the schema of the Clipboardo dataset. It does not explicitly name a sibling to differentiate from, but the content and 'call this first' instruction make its role distinct.

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 gives clear usage context: call this first to learn the schema. It does not explicitly state when not to use it or name alternatives, but the 'first' ordering implies it precedes other dataset tools and is sufficient for an agent to select it at the start of a workflow.

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