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

Annotations already declare readOnlyHint=false and destructiveHint=false, so the mutation/safety profile is covered. The description adds a meaningful behavioral constraint beyond the annotations: it must only be invoked at the user's request or with consent, because the product structure belongs to the team. It does not cover validation errors, permissions, or what happens to existing structure, but it adds real context the annotations do not.

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?

Two short sentences, front-loaded with the core action and followed by the consent constraint. No wasted words and nothing important buried.

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?

For a simple three-parameter create tool with full schema coverage and no output schema, the description is largely sufficient, and the consent rule fills the main behavioral gap. It does not mention required fields, the language/workspace convention for title, or what a successful call returns, but nothing critical is missing.

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 100% – title, desc, productID each carry their own description in the schema. The description adds no parameter-level syntax, format, or constraint information, so the baseline of 3 is appropriate when the schema does the heavy lifting.

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?

States a specific verb and resource ('Creates a product component'), and the sibling set contains both component_update and module/feature create tools, so the resource is clearly distinguished. An agent can immediately tell this is a creation tool for the component entity.

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?

Gives an explicit precondition: 'Only at the user's request or with their consent,' which is real guidance about when to invoke it, not just what it does. It does not name a sibling alternative (e.g., component_update) or state when not to use it, so it falls short of the top score.

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