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

The annotations already establish read-only, idempotent, non-destructive, and closed-world behavior. The description adds valuable privacy and scoping context: no private data is loaded publicly, and signed-in connections use a scoped private record.

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 compact at three sentences and introduces the key mode distinction early. Some phrasing, especially 'local-file template', remains unclear, but there is little outright filler.

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 tool with rich annotations and an output schema, the description covers mode behavior and privacy adequately. It still leaves the sole input parameter and the practical meaning of 'local-file template' or 'recommended choices' unexplained, which limits completeness.

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?

The schema has one optional nested 'preferences' object with 0% description coverage, and the description never mentions that parameter or explains what passing it does. Because the schema leaves it undocumented, the description should compensate but does not.

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 says it returns 'recommended choices and a local-file template' and distinguishes anonymous from signed-in behavior, indicating a read operation around preferences. However, 'recommended choices' and 'local-file template' are not concretely defined, so the exact resource returned remains somewhat vague despite the tool name.

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 gives implied usage context by stating that anonymous service calls return public recommendations while signed-in connections use a scoped private preference record. It does not explicitly say when to choose this tool over siblings such as set_job_preferences or get_job_templates, nor does it state exclusions.

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