Call a uStore endpoint

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

Without annotations, the description carries the burden, and it does add useful behavioral context: authentication is server-side, and non-GET methods are refused unless writes are explicitly enabled. However, it does not clarify what 'explicitly enabled' means, nor does it describe errors, response behavior, or side effects.

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?

Four short sentences deliver the essential facts without filler. The most critical constraints and behaviors are placed up front, and every sentence earns its place.

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?

The description is adequate for a generic endpoint caller, covering auth, path substitution, and write protection. However, the ambiguous 'writes explicitly enabled' condition and the lack of any guidance about the response format or failure modes leave meaningful gaps for an agent choosing to invoke likely mutating endpoints.

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 coverage is complete, but the description adds meaningful context beyond the schema by explaining how pathParams fill placeholders and by adding an operational constraint on the method parameter. This behavior cannot be inferred from the input schema alone.

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 uses a specific action ('Execute a request against the uStore BackOffice REST API') and clearly identifies the target resource and mechanism. It distinguishes the tool from siblings like list_endpoints or describe_endpoint by being the actual invocation tool.

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?

The intended use—executing a request—is implied by the name and description, but there is no explicit guidance about when to choose this against discovering or describing endpoints. The write-refusal note is a restriction, not a usage guideline with alternatives.

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