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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety and scope are covered. The description adds topical scope but says nothing about freshness (the phrase 'at launch' hints at a point-in-time snapshot without explaining it) or what form the answer takes. Modest added value over the annotations.

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 short sentence with no filler, and the subject matter is front-loaded. It is efficient, though a verb would have made it a fully self-sufficient call description.

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 parameterless, read-only lookup with no output schema, the description's job is to convey the content scope, which it does in outline. The ambiguous phrase 'at launch' and the absence of any hint about the returned format or coverage leave the agent with an incomplete picture of what it will actually receive.

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 the schema places no documentation burden on the description; baseline 4 applies. Nothing in the description misdescribes the (empty) input contract.

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 names a specific topical resource — how employers post a role on VA Jobs and the associated cost — which is concrete enough to distinguish from support/legal/FAQ siblings. However, it is a noun phrase with no verb, so the agent must infer that the tool *retrieves* this information, and it does not explicitly differentiate itself from close siblings like get_va_info or get_platform_overview.

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?

There is no statement of when to call this tool, when not to, or which sibling to prefer for overlapping employer/company questions. The agent is left to infer usage entirely from the topic phrase.

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