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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered elsewhere. The description adds only the notable behavior that omitting the vertical yields the full table rather than erroring or defaulting. It says nothing about output shape, pack size, or whether the components are literal copies of sibling outputs.

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 sentence with no filler, and the three deliverables are front-loaded. The middle clause "the cost-of-inaction line for a vertical (or the full table)" is slightly ambiguous, since the full-table scope could apply to the whole pack rather than just that line.

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 one optional, fully described parameter and no output schema, the description carries the burden of explaining the return payload. It names the three component groups but not their structure, ordering, or volume, which matters for a composite 'pack' tool. It is adequate to choose the tool but thin for predicting what comes back.

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?

Schema coverage is 100%, so the vertical parameter's accepted forms (slug, name, alias, case-insensitive) are already documented. The description contributes one extra fact beyond the schema: that the parameter is optional and its absence returns the full table. That is a modest value-add on top of the baseline for fully described schemas.

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 lists the content bundled by the tool (requirements, concerns, cost-of-inaction line, platform capabilities), so an agent can infer it returns a composite pack. But there is no verb and no differentiation from close siblings like get_requirements, get_concerns, and estimate_cost_of_doing_nothing, which appear to return the same components individually. Purpose is recognizable but not disambiguated.

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 or when-not-to-use guidance is given, and the obvious question -- why request this bundle instead of the individual sibling tools -- is left unanswered. The only hint is the parenthetical "(or the full table)", which implies omitting the parameter returns all verticals rather than guidance on selecting this tool.

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