Api role assignments update

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

The annotations already indicate this is a non-readonly, idempotent, non-destructive, open-world operation. The description adds no useful behavioral context such as required permissions, what the body changes, or what happens on success, and its 'viewed or edited' wording is vague for an update 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?

The description is a single short sentence with no wasted words, but it is generic and under-specified rather than informative. Its brevity does not compensate for the missing update semantics.

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 tool with no output schema and 0% schema description coverage, the description should explain the required id, the body structure, and the update effect. It provides none of that, so an agent cannot reliably invoke it from the description alone.

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% and the description does not explain either parameter. It says nothing about the required 'id' or the untyped 'body' object, leaving the agent with no semantic guidance for constructing the update payload.

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 only that it is an 'API endpoint that allows role assignments to be viewed or edited,' which does not clearly state that this specific tool updates a role assignment. It also fails to distinguish the operation from sibling tools such as role_assignments_retrieve, partial_update, and list.

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?

There is no guidance on when to use this update tool instead of the retrieve, partial_update, create, destroy, or list variants. The description provides no context, prerequisites, or alternatives.

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