Plan A Cocos Asset Pack

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

No annotations are provided, so the description must carry the burden of behavioral disclosure. It only says 'Create' and implies a plan is produced, but it does not specify side effects, permissions, or the nature of the output. Without an output schema, the agent remains uncertain about the tool's behavior beyond the intent to produce a list.

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 a single concise sentence of 18 words, front-loaded with the main action. However, it is somewhat vague and could benefit from additional structure, such as mentioning what the checklist contains.

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 has 4 parameters, no output schema, and no annotations, the description is too brief to be complete. It does not explain what a 'concrete asset checklist' is, how it is structured, or how the agent should use the resulting plan. The agent would likely need to infer or experiment.

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 input schema has 0% schema description coverage, meaning parameter descriptions are absent. The tool description does not explain any of the four parameters (assetTypes, artDirection, targetPlatform, gameDescription); it only vaguely references a 'Cocos game'. This fails to compensate for the missing schema documentation.

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 ('Create') and the resource ('concrete asset checklist'), and it distinguishes this tool from sibling generation tools by specifying it is for planning before generation. The phrase 'for a Cocos game' narrows the context.

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 implies this tool is for planning before asset generation ('so the calling coding agent can generate assets systematically'), but it does not explicitly state when to use it over alternatives or provide exclusions. The sibling tools are all generation-focused, so the context hints at a sequential workflow, but no direct guidance is given.

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