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

Annotations already declare readOnlyHint=false and destructiveHint=true, so the mutation/destructiveness profile is covered. The description adds almost nothing beyond that — it does not say that unspecified fields are left untouched, that the updates object replaces nested structures like hitbox wholesale, or warn about the destructive semantics the annotations flag.

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?

The single sentence is waste-free and front-loads the action, but its brevity reflects under-specification rather than disciplined concision — there is room to add critical detail without bloat.

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 destructive mutation tool with a nested 10-property updates object, no output schema, and zero schema description coverage, the description is far too thin. An agent could not tell from it whether partial updates are supported or how nested objects such as hitbox are handled.

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 compensate entirely, yet it only conveys that operations are keyed "by ID" (templateId) and effectively mentions the updates object as "editable properties." It does not clarify that updates is a partial-patch object, nor explain the semantics of rows/columns for sprite types, hitbox boxes, or the type enum.

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?

"Update editable template properties by ID" names a specific verb (Update) and resource (template) and scopes it to an ID. However, "editable properties" is vague and the description never distinguishes this from siblings like get_template, create_template, or update_element, so the agent must infer the boundary.

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 when-to-use guidance: no mention of when to update versus re-create a template, no prerequisite that the template must already exist, and no reference to get_template for reading current values first. The agent is left to infer usage entirely.

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