interchange_register_factory

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

Annotations already cover the safety profile (readOnly=false, destructive=false, idempotent=true, openWorld=false). The description reinforces idempotency with concrete semantics ('a class already registered is a no-op') and, critically, discloses the return shape since no output schema exists. It stops short of covering auth/permission needs.

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?

Two short sentences with the action and its key behavioral property front-loaded, followed by the return contract. Nothing is wasted, though the return-object line is dense for a short description.

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 one-parameter registration tool with annotations covering the safety profile, the description supplies what the missing output schema would have provided (the return fields) and confirms idempotency. Adequate for correct invocation; only permission/side-effect context is absent.

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 100% and the single parameter is fully documented in the schema, including an example class path and the LoadClass mechanism. The description adds no parameter-level detail beyond that, so the baseline 3 applies.

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 states specific verbs (load, register) and a clear resource (a factory UClass registered with the Interchange manager). It is unambiguous what the tool does, though it never distinguishes itself from closely related siblings such as interchange_register_translator.

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 explicit when-to-use guidance, no prerequisites, and no reference to alternative registration or module-status tools. The idempotency note gives a hint about repeated calls but does not tell the agent when this tool is the right choice.

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