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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false; the description adds detail beyond these by specifying the returned state elements (installed MCPs, connection status, accounts, tool counts). It adds enough behavioral context for an information-only tool without contradicting the annotations.

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, well-constructed sentence that front-loads the action ('Returns the current toolkit state') and then compresses the relevant data items into one list. There is no filler or redundant repetition of the tool name.

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?

This is a simple zero-parameter, read-only state getter with strong annotations; the description covers the return value contents sufficiently and there is no output schema requiring additional explanation. It is a complete description for this tool's complexity.

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 input schema is empty, so there are no parameter semantics to describe; the zero-parameter baseline is 4. The description correctly implies that no configuration or arguments are needed to retrieve the toolkit state.

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') with a defined resource ('current toolkit state') and enumerates exactly what it provides: installed MCPs, connection statuses, connected accounts, and catalog tool counts. This clearly distinguishes it from action-oriented siblings like connect, authenticate, and report_bug.

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 makes the context obvious: this is the read-only way to inspect overall toolkit status, including MCP connections and accounts. It does not explicitly name show_version or provide when-not-to-use guidance, but the stated content makes the appropriate use case clear without being misleading.

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