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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so safety is covered. The description adds only the vendor endpoint ('GET /products/search/'), and says nothing about result size limits, empty-filter behavior, or pagination semantics beyond what the schema already documents.

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?

A single front-loaded sentence plus the endpoint; no wasted prose and the filter set is stated immediately. The endpoint fragment is marginal value but not harmful.

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 12 optional parameters and no output schema, the description should say what an unfiltered call returns and how paging relates to results, but it does not; the schema does cover paging and the read-only nature is in annotations. Adequate but with clear gaps for an agent deciding on defaults.

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%, so all twelve parameters already carry meaning in the schema; the description only restates the same filter list without adding syntax, defaults, or interaction notes. 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?

The description gives a specific verb ('Search') and resource ('products') and enumerates the filter dimensions (model, category, brand, supplier, archived, references), so an agent knows exactly what the tool does. It does not name or distinguish itself from the sibling hiboutik_search_products_by_name or hiboutik_list_products, so it falls short of a 5.

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 by the enumerated filter set; there is no statement of when to prefer this over hiboutik_list_products or hiboutik_search_products_by_name, nor what happens when no filters are supplied. The agent must infer the selection rule from sibling names alone.

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