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

No annotations are provided, so the description carries the full behavioral burden, and it discloses almost nothing: not what 'connected' means (token validity vs. account link vs. capability grant), not whether it is read-only, and not whether it triggers or caches any state. For a zero-annotation tool, this is a significant gap.

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?

A single front-loaded sentence with zero filler; the key noun phrase ('connected to a Lahze account') arrives immediately. Nothing is padded or restated.

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 zero-parameter tool with no output schema, the response shape is the entire value proposition, yet the description never says what a check returns (boolean? account identity? expiry?) or what to do on false. The scope statement is adequate, but the missing return semantics leave a real gap.

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 takes zero parameters, so there is nothing for the description to disambiguate and the baseline of 4 applies. The description correctly implies no inputs are required.

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?

States a specific verb (check) and resource (connection status) scoped to 'this agent' and a Lahze account, which is enough to distinguish it from write-oriented siblings like disconnect_lahze or publish_memory. It stops short of differentiating itself from discover_lahze or get_lahze_capabilities, which plausibly also reveal connection state.

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?

No explicit when-to-use or when-not-to-use guidance, and no mention of the closest alternatives (discover_lahze, get_authorization_url). The usage is inferable from the tool's name and purpose, but the agent gets no routing help among the Lahze-related siblings.

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