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

The annotations already declare destructiveHint=true, readOnlyHint=false, and openWorldHint=false, so the safety profile is known. The description adds almost nothing beyond that: it does not say whether creating a template with an existing name or position overwrites anything (which is important given destructiveHint=true), whether it requires authentication, or what is returned. With annotations present, the bar is lower, but the silence on overwrite behavior is a notable gap for a destructive create.

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?

It is a single front-loaded sentence with no filler, and the verb leads. Its efficiency comes partly from restating the parameter list rather than adding new information, which keeps it short but low-density.

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 three-parameter create tool with no output schema, the description covers the bare minimum: what the operation is and which fields it takes. It omits the semantics of the type enum, the meaning of position ordering, and any behavior around duplicates, all of which the schema alone does not resolve.

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 has to carry the burden, and it only partly does. It names the three inputs in prose (name, content type, display position), which hints that position is a display ordering rather than a coordinate, but it never mentions the four permitted type values, the non-negative constraint on position, or the non-empty requirement for name.

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 gives a specific verb and resource: "Create a template." That is clear enough for an agent to know the operation, but it never explains what a template is relative to the many sibling creators (create_sprite, create_tileset, create_scene), even though the type enum overlaps those resources. The rest of the sentence largely restates the parameters.

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 statement of when to use this tool rather than a sibling such as create_sprite, create_nineslice, or create_tileset, and no prerequisites or exclusions. Because the tool's type enum covers sprite, environment, nineslice, and tileset, a choice among those siblings is a real decision left unexplained.

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