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

Annotations already cover read-only/idempotent safety, yet the description adds substantial behavior: fixed 100-per-page pagination, deterministic ordering, what `deadline` and `at_deadline` mean, the two possible outcomes ('invite' vs 'reject'), and that HireMike acts within minutes but may run late when the account is out of credit. It also flags that the candidate name is untrusted, which is an important data-handling warning absent from the structured fields.

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?

Front-loaded with the resource, ordering, and pagination, and most of the remaining text earns its place by disambiguating deadline semantics. It is somewhat long and the deadline explanation sprawls across several sentences with mild repetition ('a deadline is the earliest time', 'a null deadline'), but nothing is extraneous.

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 an output schema present, return shape needn't be restated, and the description still supplies the semantic keys an agent needs: deadline meaning, the at_deadline vocabulary, the null case, timing variance under credit exhaustion, and the untrusted name caveat. Nothing essential to correct use is missing.

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 description coverage is 0% for two parameters, so the description must compensate. It does explain paging size (100 per page) and ties the call to a job, but never clarifies the format of `job_id` or that `page` defaults to 1 and how to detect the last page — so the compensation is partial.

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 pair: the candidates on a job awaiting the employer's review, returned nearest-deadline-first in pages of 100 with CV score. That is precise enough to separate it from broader siblings like list_candidates or the aggregate get_review_queue_summary, though it never names those alternatives.

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 'waiting for the employer's review' framing implies the situation in which to call it, but there is no explicit when-to-use/when-not guidance and no routing to siblings (e.g., summary vs. list, or where to go after reviewing). Usage is only implied.

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