Api user groups partial update

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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false and openWorldHint=true; the description adds nothing beyond them. Worse, "viewed or edited" blurs read and write semantics on a tool whose annotations mark it as a mutation, and it says nothing about merge/partial semantics or permission requirements.

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?

It is short, but brevity without substance is under-specification rather than conciseness. The single sentence carries no actionable information and is boilerplate copied from the DRF endpoint docstring.

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 a free-form body, no output schema, and zero parameter documentation, the description covers none of what an agent needs. Nothing explains the payload shape, the response, or the effect of the call.

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 only substantive parameter is a free-form "body" object with additionalProperties: true. The description does not enumerate a single field, so an agent has no way to know what to put in the patch payload — the schema cannot compensate here.

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?

"Allows user groups to be viewed or edited" restates the resource name without naming the operation. It never says this is a PATCH/partial update, so from the text alone an agent cannot distinguish it from the sibling user_groups_update, user_groups_retrieve, or user_groups_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?

No when-to-use guidance at all: no mention of partial-vs-full update, no prerequisites, no alternatives. The only cue is the word "edited", which is far too weak given that four sibling tools operate on the same resource.

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