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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds one genuine behavioral fact beyond the annotations — that this is a compatibility alias — but says nothing about return shape, and notably fails to name the canonical tool it aliases, which is the most decision-relevant behavior for an alias.

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 sentence with no wasted words, and the key qualifier ('compatibility alias') is front-loaded. It is appropriately sized, though 'Watermelon entry' is a slightly opaque noun choice.

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 read-only alias tool the safety story is complete via annotations, and no output schema means return values need not be described. But the description omits the two things an agent most needs about an alias: which tool it mirrors and whether it is deprecated in favor of that tool.

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%, so the description must carry the load; it names both parameters and their roles ('by kind and slug'), which matches the two required fields. However it explains nothing about the kind enum values (components, blocks, dashboards, templates) or slug format, leaving the enum meaning entirely to the schema.

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?

It states a verb ('getting') and a resource ('one Watermelon entry'), plus the lookup keys, so the basic operation is inferable. But 'compatibility alias' is vague and the tool is not differentiated from siblings like get_component or list_catalog_entries — an agent cannot tell which tool this actually duplicates or when it is the right one to call.

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 phrase 'compatibility alias' weakly implies this exists for backwards compatibility, but there is no explicit when-to-use, when-not-to-use, or named alternative. An agent is left to guess whether to prefer this over get_component.

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