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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds scope ('network-wide') but says nothing about the time window, granularity, or whether the timeline is bounded — notable given the tool accepts no parameters at all.

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 no filler — the verb, scope, and intended application all appear immediately and nothing is repeated.

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?

With no input schema, no output schema, and no annotations beyond read-only safety, the description carries the full burden of explaining what comes back. It names the data ('demand vs supply timeline') but leaves the return shape, time horizon, and granularity unstated, which is a meaningful gap for a parameterless reporting tool.

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 per the rubric the baseline is 4; there are no parameter semantics for the description to clarify or omit.

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 ('Get') and a specific resource ('network-wide demand vs supply timeline data'), which an agent can distinguish from nearby siblings like get_top_demand or submit_demand. It stops short of explicitly contrasting itself with those siblings, so it is clear but not differentiated.

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 phrase 'for capacity planning and market analysis' implies a use context, but there is no explicit when-to-use/when-not guidance and no named alternative for related queries such as get_top_demand or get_depin_stats. Usage is inferred rather than stated.

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