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

Annotations already cover readOnly, idempotent, openWorld and non-destructive semantics, so the bar is lower. The description adds useful context beyond them: the default sort order and the fact that results contain personal data, which is a meaningful privacy disclosure for an agent handling the response.

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?

Three short, front-loaded sentences plus the endpoint reference; the newest-first behavior and personal-data caveat come early. No wasted text.

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, and the description does not indicate what fields a candidate application record contains or the response envelope shape. It covers filters, ordering and privacy adequately but leaves the return payload entirely unspecified for a list tool without structured output documentation.

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 100%, so the schema already documents page, limit, order, search and both date parameters with defaults and constraints. The description only restates search-by-name and date filtering and adds no syntax or format detail beyond the schema, making the baseline 3 appropriate.

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 resource (candidate applications of the company) and states the default ordering ('newest first'), plus the endpoint. It is clear what the tool returns, but it does not explicitly differentiate itself from the singular sibling talenta_get_candidate.

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?

It states what can be done ('search by name, filter by application date') but gives no explicit when-to-use/when-not guidance or named alternatives such as talenta_get_candidate for retrieving a single candidate. Usage is implied rather than prescribed.

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