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

With no annotations, the description carries the full burden. It does add real value by declaring ordering ('soonest first') and cost ('Free'), which tells the agent there is no billing or approval gate. It is silent on pagination, result caps, and whether an empty result means no upcoming changes or an error.

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 covering what, scope, ordering, audience, and cost, with no repetition or filler. The trailing 'Free.' is terse but informative rather than wasted.

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 no-required-parameter read tool with no output schema and full schema coverage, the description supplies the essentials: the resource, the date-window scoping, ordering, and cost. Only the absence of pagination/empty-result behavior keeps it from being fully complete.

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 both parameters (days with its 1-730 range and default 365, from_date with its format and default) are already fully documented in structured data. The description's 'date window' phrasing adds no format or semantics beyond that, so the baseline 3 applies.

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 and resource ('Lists pay transparency laws and amendments'), the scope ('starting in a date window'), and the ordering ('soonest first'), so an agent knows exactly what it gets. It does not, however, distinguish itself from the sibling list_pay_transparency_laws, which an agent could easily confuse it with.

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 clause 'so a recruiter or HR agent can prepare' implies the usage context but states no when-to-use condition versus list_pay_transparency_laws, and gives no exclusions or prerequisites. It is enough to guess intent, not enough to route reliably between siblings.

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