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

The annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the read-only, non-destructive behavior is well-covered. The description adds the conditional outputs (authenticated:true with empty pending[] vs. connect_url when credentials missing), which is useful context beyond annotations. It does not disclose details like rate limits or side effects, but given the annotations, a score of 3 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 concise, two sentences, and front-loads the core purpose. It efficiently uses limited space to explain both success and failure states. It is structured well, with the first sentence stating the action and the second explaining the conditional results. No wasted words, though it could be slightly more explicit about usage.

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 sheet has no parameters and no output schema, the description is the primary source of operational detail. It covers both connected and missing-credentials states, but does not describe the response format for the per-install URLs or clarify how the return relates to sibling tools. For a zero-parameter status tool, this is adequate but not fully comprehensive.

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 carries no burden for parameter semantics. The schema coverage is 100% (vacuously), and the description provides a clear overview of the output states based on connection status. Thus, the description adds value by clarifying what the tool returns without parameters.

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 indicates the tool returns connection status and URLs, and specifies a condition (all providers connected) that yields authenticated:true and empty pending[]. However, it does not explicitly contrast with sibling tools like 'authenticate' or 'toolkit_info', leaving differentiation somewhat implicit.

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 this tool is for checking connection status, but does not explicitly state when to use it over siblings like 'authenticate' (which likely initiates authentication) or 'toolkit_info'. No exclusions or alternative usage guidance is provided, but the context of returning status suggests appropriate use for status checks.

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