agent_hub_status

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

No annotations are provided, and the description only includes a bare '[L:READ]' hint. There is no disclosure of potential side effects, authentication needs, or other behavioral traits beyond the read-only implication.

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 very brief and uses structured tags efficiently. However, it could be more informative without adding significant length, such as clarifying the return value.

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?

With no parameters, annotations, or output schema, the description fails to provide sufficient context about what the tool returns or its role. The single instruction about agent_catalog is insufficient for a complete understanding.

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, so the description needs to add minimal value beyond the schema. The instruction to call agent_catalog first provides operational context, meeting the baseline for a parameterless tool.

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 indicates a read-only system tool and instructs to call agent_catalog first, but it does not explicitly state what status is being checked or what the tool outputs. The purpose is implied but ambiguous.

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 only provides a prerequisite (call agent_catalog first) but lacks guidance on when to use this tool versus alternatives. No context on selection criteria is given.

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