Api ebios rm studies partial update

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

Annotations already declare readOnlyHint=false, idempotentHint=false, destructiveHint=false, openWorldHint=true; the description adds nothing beyond them and says nothing about what a partial update changes, whether omitted fields are preserved, or what response is returned. The vague 'viewed or edited' phrasing further muddies a mutation tool's behavior.

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 short sentence with no waste, but the brevity is under-specification rather than efficiency — there is nothing front-loaded that an agent can act on.

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 mutation endpoint with no output schema and zero parameter documentation, the description omits nearly everything needed: which fields are updatable, what the body uses for, and how errors or partial semantics behave.

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 0% for both parameters, so the description carries the full burden, yet it never mentions the required study `id` or that `body` is the partial field payload object. Zero semantic value added.

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 text is generic DRF boilerplate: 'allows ebios rm studies to be viewed or edited' names the resource but never states the actual verb (partial update / PATCH) nor distinguishes it from the sibling studies_retrieve, studies_update, or studies_list. An agent cannot tell from this sentence whether it reads or writes.

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 when-to-use guidance, no mention of the update vs partial_update vs retrieve alternatives that exist among siblings, and no prerequisites (auth, permissions, existing study id).

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