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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds 'current' (freshness framing) and 'public' (visibility scope), which is modest added value; it says nothing about refresh cadence, rate limits, or what an autonomous Scout run actually yields.

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 the verb first and no filler. It is efficient, though the compounded noun list is slightly dense rather than maximally sharp.

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?

There is no output schema, so the description carries the load of explaining what comes back, and it only names three categories without describing shape or content. For a snapshot tool whose return is the whole point, this is adequate but thin.

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 no per-parameter semantics to document; the baseline for a parameterless tool applies. The description correctly implies the snapshot is unfiltered, which is consistent with an empty schema.

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 ('Return') and names the resources: 'public demand signals, clusters, and autonomous Scout runs.' This is more than a restatement of the name/title, though 'Scout runs' is jargon and no sibling (e.g. find_capability, list_capabilities) is contrasted to aid selection.

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 when-to-use context, prerequisites, or alternative routing is given. With siblings like find_capability, list_capabilities, and system_status available, an agent gets no signal about when a snapshot is preferable to those.

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