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

With no annotations, the description carries the full burden of behavioral disclosure. It states 'AI-synthesized,' 'Coverage: Global,' and per-endpoint prices, but does not explain output format, parameter requirements per endpoint, error behavior, or that this is a read-only intelligence service. The runtime behavior of the tool remains largely opaque.

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 front-loads the purpose with a single-sentence summary, then provides a clean bulleted list of all endpoints and prices. It is easy to scan and informative without being verbose, though the pricing details could be considered secondary and perhaps belong in a separate field.

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 23 parameters, 10 actions, no output schema, and no annotations, the description is incomplete. It fails to specify which parameters are relevant for each action, how results are returned, or what input combinations are valid. An agent would struggle to invoke the tool correctly beyond selecting an action.

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?

All 23 parameters have schema descriptions (100% coverage), so the baseline is 3. However, the description adds no parameter guidance—it never maps endpoints to required or recommended parameters (e.g., 'value' likely needs an address or zip, but that mapping is absent). The terse schema descriptions like 'city' and 'Room' are minimally helpful, and the description does not compensate for their brevity.

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 opens with 'Global home intelligence API' and enumerates ten specific endpoints (value, neighborhood, improve, etc.), making its domain and scope obvious. It distinguishes itself from sibling domain tools like 'cryptopulse' and 'climapulse' by being explicitly home-focused, though it describes multiple sub-actions within the tool rather than a single specific operation.

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 use for home-related queries via the endpoint list, but never explicitly states when to prefer this tool over alternatives or how to choose among the ten actions (e.g., 'maintain' vs 'maintenance'). It lacks any when/when-not guidance, forcing the agent to infer usage from endpoint names.

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