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

The description goes beyond the readOnlyHint and idempotentHint annotations by detailing conditional behavior: when all providers are connected it returns authenticated:true and empty pending[], and when credentials are missing it returns connect_url and per-install URLs. This provides meaningful behavioral insight not present in 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 two sentences with no fluff. It front-loads the core purpose ('Returns connection status and URLs') and then efficiently explains conditional outputs. Every word 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?

For a tool with no parameters and no output schema, the description covers the main use cases: connected vs. missing credentials. It could be slightly clearer about what 'pending' represents or what the URLs are for, but it is quite complete for the tool's simplicity.

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 is 4 per the rubric. The description does not need to document parameter behavior since there are none, and it correctly focuses on output semantics instead.

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 connection status and URLs', using a specific verb and resource. It also distinguishes itself from siblings like 'authenticate' by focusing on status rather than the authentication action. The behavioral details (authenticated:true, pending[]) add specificity.

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 used to check connection status and get URLs when needed. However, it does not explicitly mention when NOT to use it or how it differs from siblings like 'authenticate' or 'toolkit_info'. The usage context is clear but not explicitly contrasted with alternatives.

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