get_model_ui_component

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

Annotations already establish readOnlyHint=true, so the description's job is to add scope detail, and it does: it declares the read is limited to unpublished definitions and that publication state is not inferred (a meaningful caveat about result interpretation). It stops short of describing error behavior when the component is published-only or how the ETag should be used for concurrency.

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?

A single dense sentence with the core purpose front-loaded and no filler. 'Publication state is not inferred' is slightly cryptic but carries real information, so nothing is wasted.

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 usefully enumerates what comes back (definition, inventory, fingerprint, ETag) despite there being no output schema, but with four parameters at 0% coverage and a non-obvious alias/anyOf structure, the definition leaves the caller guessing how to construct a valid request.

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 description never mentions id, logical_name/logicalName, or kind. The schema's enum and regex patterns give some self-evident structure, but the alias relationship (logicalName → logical_name) and the anyOf required-combinations are left entirely unexplained, so the description fails to compensate for the coverage gap.

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?

States a specific verb ('Read') and a precise resource ('native unpublished system form/view definition'), plus the return artifacts (structural inventory, SHA-256 fingerprint, ETag). The 'unpublished' qualifier implicitly separates it from edit_model_form/edit_model_view and list_model_ui_components, though it never names those siblings.

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 or when-not guidance and no named alternative (list_model_ui_components, edit_model_form, edit_model_view are all nearby). The only directional hint is 'unpublished', which the agent must infer means published definitions are out of scope.

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