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

No annotations are provided, so the description carries full burden. It states this is an update operation (implying mutation), but doesn't disclose behavioral traits like required permissions, whether changes are reversible, error handling, or side effects. The description mentions that parameters can be left empty to 'keep current', which is useful context about partial updates, but lacks other critical behavioral details for a mutation tool.

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 well-structured with a brief purpose statement followed by a parameter glossary. Every sentence earns its place by explaining parameter behavior. It could be slightly more concise by combining some parameter explanations, but overall it's efficiently sized for 9 parameters.

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 this is a mutation tool with 9 parameters, 0% schema coverage, no annotations, but with an output schema, the description does an adequate job. It explains all parameters thoroughly, but lacks behavioral context (permissions, side effects) and usage guidance. The output schema existence means return values are documented elsewhere, so the description doesn't need to cover them.

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 description must compensate fully. It provides clear semantics for all 9 parameters, explaining each one's purpose and noting that leaving them empty/omitted preserves current values. This adds significant value beyond the bare schema, which only shows titles and types without explaining behavior like 'leave empty to keep current'.

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 tool's purpose as 'Update an existing product's fields' which is a specific verb+resource combination. It distinguishes itself from sibling tools like 'netlicensing_create_product' (creation vs. update) and 'netlicensing_get_product' (read vs. write). However, it doesn't explicitly mention what distinguishes it from other update tools like 'netlicensing_update_bundle' or 'netlicensing_update_licensee' beyond the resource type.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing an existing product), compare it to sibling update tools for other resources, or indicate scenarios where this update is appropriate versus creating/deleting. The agent must infer usage from the tool name and context alone.

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