cart_generate_system

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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It only states that it generates an implementation, with no detail on what files are created, whether existing code is overwritten, whether it scaffolds a full system, or what side effects occur. This is a significant transparency gap.

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 with no wasted words, and it is front-loaded with the action. However, it is also severely under-specified: there is no structure, no parameter context, and no behavioral detail, so the conciseness is more a symptom of missing content than good organization.

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 no annotations, no output schema, and an undocumented optional api_key, this definition is far from complete. It does not say what technology the shopping cart implementation targets, what files or modules are created, how the api_key is used, or what the directory should contain. An agent would need to infer most of the expected behavior.

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 coverage is 50%: only 'directory' has a description ('Project directory'), while 'api_key' has none. The description adds no additional meaning to either parameter, so the undocumented api_key remains entirely unexplained. This fails to compensate for the schema's incomplete parameter 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 states a clear verb and resource: 'Generate shopping cart implementation'. It is not a tautology and conveys the core action. However, it does not distinguish this tool from close siblings like cart_add_persistence or cart_add_promotions, so it stops short of full clarity.

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 gives no guidance on when to use this tool instead of alternative cart-related tools or the many other generate_* tools. There is no mention of prerequisites, expected project structure, or technology stack. An agent cannot infer when this is the right choice.

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