products_create

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

With no annotations provided, the description carries full burden for behavioral disclosure. It mentions the tool returns a copy of the created object including ID, which is useful. However, it doesn't address critical aspects like required permissions, whether this is a mutating operation (implied but not stated), error conditions, rate limits, or side effects. For a creation tool with zero annotation coverage, this leaves significant gaps.

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, efficient sentence that communicates the core action and return value without unnecessary words. It's appropriately sized for a basic creation tool, though it could be slightly more informative given the complexity of the nested parameter structure.

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 (1 parameter with nested object containing 6 properties), no annotations, no output schema, and 0% schema description coverage, the description is insufficient. It doesn't explain the parameter structure, available properties, validation rules, or what the returned object contains beyond 'including the ID'. For a creation tool with rich parameter requirements, this leaves too much undefined.

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 0%, so the schema provides no parameter descriptions. The description mentions 'properties' but doesn't explain what properties are available or their semantics. It doesn't add meaningful information about the nested object structure or the specific fields like name, price, sku, etc. Baseline is 3 when schema does heavy lifting, but here the schema lacks descriptions, and the description doesn't compensate adequately.

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 verb ('Create') and resource ('a product'), specifying that it creates a product with given properties and returns the created object. It distinguishes from sibling tools like products_list or products_read by focusing on creation, though it doesn't explicitly contrast with products_batch_create for bulk operations.

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. It doesn't mention prerequisites like authentication, compare with batch creation tools for efficiency, or indicate scenarios where this single-create tool is preferred over batch operations. The description only states what it does, not when to use it.

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