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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is well covered. The description adds useful detail about what the returned state includes, but it does not disclose additional behavioral traits such as whether the state is a live snapshot or cached, or any rate-limit/availability considerations.

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, front-loaded sentence that leads with the action and resource, then enumerates the specific data items. Every word earns its place; there is no filler or repetition of schema/annotation information.

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 informational tool with strong annotations, the description fully enumerates the categories of returned information: installed MCPs, connection status, connected accounts, and catalog tool counts. No output schema exists, but the description sufficiently bounds what an agent should expect.

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 parameter semantics are largely not applicable. Per the calibration baseline, a zero-parameter tool receives a 4; the description appropriately focuses on what the call returns rather than parameter behavior.

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 clearly identifies the resource ('current toolkit state') with enumerated content: installed MCPs, connection status, connected accounts, and catalog tool counts. This makes it easy for an agent to distinguish this from sibling tools like show_version or connect.

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: call this when you need an overview of the toolkit's installed integrations and their status. However, it does not explicitly state when to prefer this over siblings like show_version or marketplade, nor does it mention any exclusions or alternatives.

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