Generate Cocos Tileset

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

With no annotations, the description fully shoulders behavioral disclosure. It mentions 'seamless-ish' (non-committal quality) but omits side effects (e.g., file creation, potential overwrites), output specifics, or required permissions. A mutation tool like this needs more transparency.

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 concise (16 words) and front-loaded with verbs, but it omits essential details. Conciseness here comes at the cost of completeness, earning a middle score.

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?

Given the tool's complexity (9 parameters, nested objects, no output schema), the description is far too sparse. It does not explain tile metadata format, parameter roles, or output behavior, making it inadequate for correct usage.

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 only 33% (3 of 9 parameters documented), and the tool description adds zero parameter information. It fails to compensate for the low coverage, leaving agents uninformed about key parameters like seed, tileCount, or postprocess.

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 action (generate, pack, emit), the resource (tile sprites, tileset sheet, tile metadata), and distinguishes from sibling tools like generate_sprite (single sprite) and generate_sprite_sheet (arbitrary sprites) by specifying 'seamless-ish' tiles and packing into a tileset.

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 on when to use this tool vs alternatives, no prerequisites or contraindications mentioned. The description is purely functional without context for selection.

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