Api privacy data recipients 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, so the description's only job is to add semantics — and it adds none. It does not state that only supplied fields are modified (the defining trait of a partial update), what happens to omitted fields, permission requirements, or whether a response body is returned.

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 a single short sentence, so it is not bloated, but length is achieved by saying nothing — boilerplate that would be identical for hundreds of sibling endpoints. No front-loaded statement of operation or scope.

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 an opaque free-form payload, no output schema, and no parameter documentation, the description omits everything an agent needs to call it safely. It does not even convey which object type or fields are being updated.

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 two parameters are opaque: 'id' is an unconstrained string and 'body' is an untyped free-form object or null defaulting to null, with no hint about which recipient fields it accepts. The description compensates for none of this, so an agent has no basis for constructing a valid 'body' 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 is the generic Django-REST boilerplate 'API endpoint that allows data recipients to be viewed or edited,' which restates the title and resource rather than stating the operation. It never says this is a PATCH-style partial update, so an agent cannot distinguish it from the sibling *_retrieve, *_update, *_list, or *_create endpoints on the same resource.

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 when-to-use guidance at all: nothing says to prefer *_partial_update over *_update (full replace), or how it relates to *_retrieve/*_list for reads. The word 'viewed' even suggests read usage that this endpoint does not serve, leaving the agent to infer intent from the tool name alone.

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