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

The annotations already declare it as read-only, idempotent, and non-destructive. The description adds meaningful context about what information it returns (installed MCPs, connection status, accounts, catalog counts), which is beyond the annotations. It does not contradict any annotation, and the combination of annotations and description provides a clear behavioral picture.

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, focused sentence that front-loads the purpose and enumerates the returned data. No filler or redundant phrasing; every word contributes.

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 read-only tool with no output schema, the description fully explains what the tool returns crossing all relevant aspects. It covers the essential information an agent needs to decide when to invoke it.

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 baseline per the rubric is 4. Schema coverage is 100% (vacuously true). The description doesn't need to add parameter details since there are none, and it accurately describes the tool's output.

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 uses a specific verb ('Returns') and identifies the resource ('current toolkit state') with enumerations of what it includes (installed MCPs, connection status, accounts, catalog counts). It clearly distinguishes from sibling tools like show_version and jucesp_redesim_protocolo_consultar, which serve other purposes.

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?

While the description doesn't explicitly state when not to use it, the purpose strongly implies it's the go-to for a high-level overview of the toolkit's configuration. It could benefit from a note that it doesn't perform actions or authenticate, but given the sibling list and the clear scope, the context is adequate.

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