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

No annotations are provided, so the description carries the full burden of disclosure. It reveals that the response contains pairedExtension, pairingUrl, current usage, and connected devices, and defines the branch behavior when pairing is false. It doesn't cover auth/rate limits, but for a read-type status call this is solid.

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?

Two sentences with no filler, front-loading the return value first and the workflow guidance second. Every sentence contributes operational value.

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 one-parameter status tool with no output schema, the description covers the main response content and calling context well. The main gap is the undocumented returnTo parameter, so it isn't fully complete.

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?

Schema description coverage is 0%, and the description never mentions the single optional returnTo parameter. The schema offers only a name and URI format, leaving the agent without any explanation of what the parameter does or when to pass it.

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?

Description states a specific verb ('Returns') and resource (account status: paired browser extension, current usage, connected devices), and ties it to a concrete next step ('Use this BEFORE create_post'), which differentiates it from siblings like get_post_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?

Explicitly instructs 'Use this BEFORE create_post' and provides a conditional action ('if pairedExtension is false, surface pairingUrl to the user'). It doesn't mention when not to use it or compare with alternatives, so it falls just short of the most explicit bar.

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