get_hub_tool_schema

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

The description indicates a read-only retrieval operation, but does not explicitly state non-destructiveness or authentication needs. Without annotations, this is adequate but could be more 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 brief, front-loaded with the main purpose, and each sentence adds necessary detail without redundancy.

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 schema retrieval tool with an output schema, the description covers purpose, parameters, and return type adequately. No critical information is missing.

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 identifier parameter has 0% schema coverage, but the description adds format guidance ('hub:server:tool or server:tool'), which is valuable beyond the bare type in the schema.

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's action ('Get the input schema') and resource ('hub tool'), distinguishing it from sibling tools like `execute_hub_tool` or `discover_hub_tools`.

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 usage context: when you need the input schema of a hub tool. It provides the return type and parameter format but does not explicitly mention when not to use or alternatives.

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