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

readOnlyHint=true already establishes the safety profile, so the bar is lower. The description usefully adds what is returned per job, but says nothing about pagination, result limits, or whether the list is scoped to the caller's account — meaningful gaps for a list endpoint.

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?

Two sentences, no filler, with the field inventory front-loaded and the API mapping condensed into a trailing clause. Every element earns its place.

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 carries the burden of describing the return payload, and it does so by naming the four key fields. It stops short of noting pagination or result ordering, which would matter for an agent consuming a long job list.

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 tool takes zero parameters and schema coverage is 100%, so the baseline of 4 applies per the rubric. There is nothing parameter-related the description needed to compensate for.

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 ("List fine-tuning jobs") and enumerates the fields surfaced (status, base model, output model name, training settings). It is clearly distinct from together_get_fine_tune in intent, but the description never explicitly names a sibling, so differentiation still depends on the reader inferring singular-vs-list semantics.

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 this is the browse-everything call versus together_get_fine_tune for one job, but there is no explicit when-to-use/when-not guidance or mention of alternatives such as together_list_fine_tune_events. Adequate but leaves routing to inference.

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