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

readOnlyHint=true already covers the safety profile, and the description goes beyond it by naming the payload contents (intro, tasks, requirements, page URL) and the regional scope of the data. It does not say what happens when the job is unknown or ambiguous, which is the main remaining behavioral gap.

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?

One front-loaded sentence carries purpose, content list, locale, and scope with no filler. The comma-separated content list is slightly dense but every clause adds information.

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 no output schema, the description must convey return content, and it does so by naming the fields and the page URL. For a single-parameter read tool with a readOnly annotation, that is nearly complete; only the not-found/ambiguity behavior is unstated.

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% and already gives an example value, so the baseline is 3. The description adds real meaning by stating that job titles are Dutch, which tells the agent the expected language of the slug/name and is not in the schema.

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 (get the job description of a job) and enumerates the returned content: intro, what the job involves, tasks, requirements, plus the page URL. It adds a geographic scope (Netherlands) and a locale constraint (Dutch job titles). It does not explicitly contrast with get-vacancy, though the resource itself is clearly distinct.

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?

Usage is only implied: an agent can infer it should call this when it needs the descriptive content of a job rather than a posting. There is no explicit when-to-use, when-not-to-use, or pointer to a sibling such as get-vacancy for actual openings, so the agent must reason about the boundary itself.

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