outremer_explain_scope

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

No annotations are provided, so the description carries the behavioral burden. It states that the tool 'explain[s]' content, but it does not disclose output format, whether it returns static text, or any side effects. For a zero-parameter explanation tool, this is minimally 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 a single sentence that immediately states the tool's purpose. Every word contributes value, and there is no redundant or filler content.

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 orientation tool with no inputs and no output schema, the description is sufficiently complete for an agent to select and invoke it. It could arguably name example source-combination patterns, but that is not necessary for basic correct use.

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 has zero parameters and the schema coverage is 100%, so there are no parameter semantics to clarify. The description adds no parameter info, but none is needed; the baseline for a no-parameter tool is met.

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 the tool's role as an orientation/explanation tool: it explains what the MCP is useful for and how to combine sources. This is distinct from sibling tools like list/get/search, 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 implies the agent should use this tool to understand the MCP's overall utility and source-combination strategy, which is clear context for when to invoke it. It does not explicitly state exclusions or alternatives, but the purpose itself is the usage guidance.

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