pixelart_create_tileset

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

The description states that the tool creates a new tileset and returns a JSON confirmation, which aligns with the annotations (readOnlyHint=false, destructiveHint=false). However, it does not disclose what happens if a tileset with the same ID already exists, nor does it mention any side effects beyond creation.

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 (3-4 lines) and front-loaded with the purpose. It avoids unnecessary fluff. However, the use of a docstring style with 'Args:' and 'Returns:' is slightly verbose but acceptable.

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 basic purpose and return format, and the output schema exists to detail the return structure. However, it lacks context about default values (e.g., ppu defaults to 16), constraints, or how this tool fits into the broader workflow with sibling tools like pixelart_suggest_tile_size.

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?

With 0% schema description coverage, the description merely lists parameter names (tileset_id, tile_width, etc.) without explaining their meaning beyond the names. For example, 'ppu' is ambiguous (pixels per unit), and no defaults or constraints are mentioned. The description adds minimal value over 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?

The description clearly states the tool's purpose: 'Create a blank tileset sheet (grid of equally-sized tile slots).' It distinguishes this creation tool from sibling tools like pixelart_set_tile or pixelart_export_tileset, which modify or export existing tilesets.

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 provided on when to use this tool versus alternatives like pixelart_import_canvas or when not to use it. The description does not mention prerequisites or scenarios where another tool would be more appropriate.

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