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

With no annotations, the description carries the full burden, but it adds little beyond the tool name. It does not disclose whether it returns occupation IDs and/or names, whether results are paginated, or whether any authorization is required, though it does imply a read-only lookup.

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?

The description is a single concise sentence with no filler and is easy to scan. It loses a point for being a sentence-fragment question instead of an explicit action-oriented phrase, but the brevity is appropriate for a one-parameter tool.

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 simple one-parameter lookup, the description plus schema is minimally sufficient to invoke the tool. However, because there is no output schema and no annotation coverage, some ambiguity remains about the exact return shape and how this differs from the inverse sibling.

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 the sole id parameter already has a clear description ('The certification id'). The tool description adds no extra meaning about the parameter, so the schema baseline of 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?

The description identifies the resource (a certification) and the focus (the occupations it serves), so an agent can infer it maps a certification to occupations. It is clear but phrased as a question rather than a directive, and it does not explicitly contrast with the inverse sibling certifications_for_occupation.

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 guidance is given about when to select this tool over certifications_for_occupation or other siblings. The inverse direction is implied by the name, but the description does not state exclusions or alternatives.

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