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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so safety is covered. The description adds only the endpoint (GET /position-titles); it does not state result-set shape, whether results are paginated (the schema hints at next_page), or ordering, so it adds little behavioral context beyond the annotations.

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 sentences, front-loaded with what the tool returns, no filler. It is arguably under-specified rather than padded, so length is not the problem.

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 read-only list tool with fully documented parameters and no output schema, the description is minimally sufficient: an agent knows what it lists and how to filter. It stops short of describing the return fields or pagination expectations, which would be needed for confident multi-page retrieval.

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 page/limit and the substring semantics of name are already documented. "Filter by name" restates rather than extends the schema, giving no extra detail on matching behavior beyond what the property description provides.

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: position titles defined in intelliHR, with a clarifying synonym ("job names") and the underlying endpoint. It is distinguishable from the sibling list_people/list_locations style tools, though the "job names" gloss risks blurring it with intellihr_list_jobs and intellihr_get_job, which are not addressed.

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 description says nothing about when to pick this over intellihr_list_jobs or intellihr_list_reference_data, nor any prerequisites. Usage is only implied by the verb "list".

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