Create Pixel Sprite

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

No annotations are provided, so the description carries full responsibility for behavioral disclosure. It does not state whether the tool executes Aseprite, writes files, requires an executable, or has side effects. The dryRun mention hints at Lua generation but does not explain execution or output behavior.

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 highly concise: two sentences, front-loaded with the primary purpose and a notable feature. There is no redundancy or filler, though the second sentence could have been repurposed for more substantive context.

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 tool is complex (nested schema with seven operation types, no output schema, no annotations), yet the description omits key context: what the sprite represents, how drawing operations map to Aseprite features, whether files are saved, and what the tool returns. The terse description is far from sufficient for such a rich 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 80% for top-level parameters, so the baseline is 3. The description adds no parameter meaning beyond what the schema already provides; for example, 'Supports dryRun' merely repeats the dryRun parameter's schema description. No effort is made to clarify the complex 'spec' nested structure.

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 'Create a sprite from structured drawing operations,' clearly identifying the verb ('create'), resource ('sprite'), and method (structured drawing operations). It does not explicitly distinguish this from sibling tools like aseprite_run_lua or aseprite_cli, but the phrasing implies a declarative, operation-based creation approach.

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?

No guidance is given on when to use this tool versus alternatives such as aseprite_run_lua or aseprite_cli. The description only mentions the dryRun feature, which is a capability detail, not a usage guideline or exclusion criterion.

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