get_product_portal_config

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

No annotations are provided, so the description must bear full responsibility. It discloses the null return and fallback behavior, which is the key behavioral trait. For a simple read operation, this is sufficient. No side effects or authorization needs are mentioned, but that is typical for getters.

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 sentences: first states what the tool retrieves, second explains null behavior and use case. No filler, every sentence adds value. Well front-loaded.

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 single parameter with thorough schema documentation, the description adequately covers the null return and context. Lacks explanation for invalid IDs or error scenarios, but for a simple getter this is acceptable.

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 100% with a detailed description of the productId parameter (UUID vs legacy, version info). The description adds no additional meaning beyond what the schema provides, so baseline 3 is appropriate.

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 'Get the per-product portal customization' and lists specific fields (business name, logo, etc.). It distinguishes from siblings like set_product_portal_config and clear_product_portal_config by being the retrieval counterpart. The B2B2C use case is mentioned, making the purpose unambiguous.

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 explains the null return behavior and fallback to seller-level config, giving context on when to expect values. It also notes the intended audience (B2B2C platforms). However, it does not explicitly state when not to use this tool or suggest alternatives, but the context implies it's the primary getter.

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