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

With zero annotations, the description must disclose side effects and safety. It states the core action (stamp PNG) and layer targeting, but omits details on overwrite behavior, reversibility, layer existence requirements, or error conditions. This leaves behavioral ambiguity.

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 description is concise and well-structured, with the core action stated first, followed by the bridging context and the layer=None behavior. Every part earns its place.

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 covers the main action and layer targeting, but leaves out coordinate system details and potential failure cases. Since output schema exists, return value explanation is not needed, but the missing coordinate origin and error handling make it slightly incomplete for a tool with no annotations.

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?

The description adds context for x,y as position and for layer's default behavior, but does not explain coordinate origin or image_path format. With 0% schema coverage, the description partially bridges the gap but not fully.

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 a clear verb, resource, and coordinate context. It explicitly mentions the bridging role for Aseprite sprites and Retro Diffusion generations, which distinguishes it from sibling tools that read or modify pixels. The layer=None note further clarifies the target layer semantics.

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 description explicitly identifies the intended use case (bridging Aseprite/Retro Diffusion content) and provides the layer=None targeting rule. It doesn't list exclusions or alternative tools, but the context is strong enough to guide selection.

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