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

With no annotations, the description must carry the behavioral burden, and it does disclose the full output surface and its boundaries, which is the main trait an agent needs here. It is silent on error behavior for an unknown SKU and does not explicitly confirm read-only semantics, but for a single-record lookup the gap is minor.

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 compact sentences: the positive scope is front-loaded, then the exclusions with sibling pointers. Every clause carries information; nothing is padding.

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?

There is no output schema and no annotations, so the description correctly compensates by enumerating returned fields and boundaries. It omits any mention of failure behavior (invalid/unknown SKU) and does not explicitly state read-only status, which keeps it just short of fully complete.

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% and the single sku parameter already documents exactness and gives an example ('DO-DRO-OG'). The description's phrase 'după SKU' and 'SKU-ul exact' repeats rather than extends the schema, so the baseline 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 retrieval action on a named resource ('Identitatea unui produs după SKU') and enumerates the exact fields returned (nume, url, imagine, galerie, categorii, tag-uri, brand, cod de bare). It explicitly distinguishes itself from siblings get_product_offer and get_product_content, so an agent can route without opening any schema.

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 explicit negative scope ('Fără preț/stoc', 'fără conținut editorial') and names the alternative tool for each excluded concern (get_product_offer, get_product_content). This is the when-not/alternative pattern, not merely implied usage.

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