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

Beyond the annotations (read-only, idempotent), the description discloses specific behavioral scenarios: what happens when all providers are connected (authenticated:true, empty pending[]) and when credentials are missing (returns connect_url for toolkit and per-install URLs). This adds transparency about conditional outputs, though it does not cover partial connectivity or error cases.

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, consisting of two clear sentences. It avoids unnecessary detail and is well-structured, presenting the main purpose first followed by conditional behaviors.

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 simple read-only status tool with no parameters, the description covers the primary output and key conditions. However, it does not address scenarios like partial provider connectivity or other potential edge cases, making it slightly incomplete but still adequate for typical use.

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 no parameters, so there is nothing to explain. The description does not introduce any implicit parameters, and the schema coverage is complete (100%). Thus, parameter semantics are fully satisfied.

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's function: returning connection status and URLs. It is specific and distinguishes it from other tools like 'authenticate' or 'marketplace' by focusing on connectivity and provider status.

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 provides conditional outcomes (all providers connected vs. missing credentials) but does not explicitly guide when to use this tool versus alternatives. It lacks direct statements like 'use this to check connectivity' or 'do not use if you need to authenticate'.

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