commerce_customer_segment

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

With no annotations, the description carries full burden. It mentions routing and scope but omits key behavioral traits: side effects, idempotency, error handling, security requirements, or rate limits. The agent gets little insight into execution behavior.

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 brief and to the point, with a clear header and bulleted args. It wastes no words, though additional context could be added without losing conciseness.

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?

Despite having an output schema, the description does not explain what the action actually accomplishes (e.g., segmenting customers by criteria). The agent cannot fully assess relevance without knowing the action's purpose.

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 0%, so the description must compensate. It adds minimal meaning: 'message' is a free-text objective, 'inputs' is an optional JSON string. This is better than nothing but still vague—no examples or expected structure for the JSON string.

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 'Run' and the resource 'commerce domain agent action customer_segment', and explains the routing mechanism and scope. However, it does not define what 'customer_segment' actually does or distinguish it from sibling tools like product_customer_segment or commerce_customer_profile.

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 mentions scope constraints but fails to set expectations for appropriate usage scenarios or prerequisites.

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