Api reference controls provider retrieve

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

The description says the endpoint allows reference controls to be 'viewed or edited', which implies a mutation capability, while the annotations declare readOnlyHint=true and destructiveHint=false. The one behavioral claim in the text conflicts with the structured safety metadata, and it says nothing about what the read actually returns.

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 sentence with no padding, which is structurally fine. However, the sentence is auto-generated boilerplate that spends its one clause on generic CRUD phrasing instead of the endpoint's actual purpose, so brevity comes at the cost of utility.

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 parameters and no output schema, the description carries the full burden of telling the agent what comes back, yet it never mentions that this is a provider/choice listing or what shape the response takes. For a 'provider retrieve' endpoint the description is essentially uninformative.

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, so there is no parameter semantics to explain; the baseline for a parameterless tool applies. The schema description coverage is 100% with an empty properties object, so nothing is left ambiguous.

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 restates the title in generic terms ('reference controls ... viewed or edited') and never explains the distinguishing feature of this endpoint: it is the provider/choice endpoint for reference controls. Nothing separates it from siblings like reference_controls_retrieve or reference_controls_list, so an agent cannot tell it apart without inspecting the route.

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 call this versus reference_controls_list, reference_controls_retrieve, or reference_controls_category_retrieve. The agent must infer usage entirely from the tool name.

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