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

With no annotations at all, the description carries the full behavioral burden. It does disclose one genuinely useful trait — missing fields are returned as null and never inferred, which stops an agent from fabricating content. However, it says nothing about read-only safety, error behavior for an unknown SKU, language coverage, or rate limits, leaving meaningful gaps for a zero-annotation 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?

Two tightly packed sentences with no filler; the field inventory is front-loaded immediately after the resource statement, and the null-semantics caveat follows. Slightly dense, but every clause carries information.

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?

With no output schema, the description must describe return values and it does, listing the content fields and the content_extra bucket plus the null convention. For a single-parameter read tool this is nearly sufficient; only error and permission behavior remain unaddressed.

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?

Only one parameter exists and schema description coverage is 100% (the schema already documents the exact SKU with an example). The description's phrase 'după SKU' adds nothing beyond the schema, so the baseline of 3 applies.

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+resource: retrieve editorial content for a product identified by SKU, and enumerates exactly what that content covers (ingredients, usage, precautions, benefits, custom mapped fields). It is clearly separable from siblings like get_product_offer (commercial data) and search_products (discovery), though it never explicitly contrasts itself with get_product, which likely also returns product data.

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?

Usage is only implied: an agent can infer it should call this when it needs descriptive/editorial text rather than pricing or search. There is no explicit statement of when to prefer this over get_product or get_product_offer, and no prerequisites (e.g., that the SKU must already exist) are given.

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