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 clear. The description adds that it reports connection status and catalog counts, which is useful but does not go beyond what the annotations suggest (e.g., no mention of side effects, but none expected). No extra behavioral details like rate limits or auth requirements are provided, but with annotations carrying the safety load, a neutral score is appropriate.

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, compact sentence that is front-loaded with the verb 'Returns' and details the key content. No waste, every phrase earns its place.

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?

Given the tool has no parameters, a rich annotations set, and no output schema, the description sufficiently covers the tool's purpose and informative value. It could mention that it is read-only or that it provides a snapshot, but the annotations already cover safety. The description is complete enough for an agent to understand what it will get.

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 0 parameters, so the schema is trivially covered (100%). The description adds meaning by describing the return content (installed MCPs, connection status, accounts, catalog counts), which is the primary value since there are no parameters to document.

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 returns the current toolkit state, specifying the resources (installed MCPs, connection status, connected accounts, and catalog tool counts). It distinguishes from siblings like connect and authenticate by卒頸 draft Knock,Oliver.

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 the tool is for querying the toolkit state but does not explicitly state when to use it versus alternatives. It offers no guidance on when to prefer this over show_version or authenticate. Context is clear (returns current state) but exclusions are absent.

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