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

No annotations are provided, so the description carries the full burden. It does add genuinely useful behavioral context by disclosing the billing model ('Flat 5 points per successful run'), which an agent should know before calling. However, it says nothing about failure modes, missing/invalid SKUs, or freshness/latency of the scrape, so significant disclosure gaps remain.

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?

One front-loaded sentence: the action and identifier forms come first, then the field inventory, then the cost note. The field enumeration is long but earns its place by telling the agent what it will get back in the absence of an output schema.

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?

For a single-parameter lookup with no output schema, the description compensates well by listing the return fields and disclosing the point cost. Only the absence of error/edge-case behavior keeps it from being 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% — the single parameter already documents that it accepts a SKU, product group ID or URL, with the same HBCV example. The description repeats this rather than adding format rules or validation semantics, so the baseline 3 for schema-covered parameters 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 ('Get') and resource ('full Hepsiburada product details') plus the accepted identifier forms, and enumerates the returned fields (name, brand, price, sellers, variants). An agent can distinguish it from run_hepsiburada_products_search and run_hepsiburada_products_reviews without opening either 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?

Usage is only implied: the identifier list (SKU, group id, URL) suggests lookup semantics, but there is no explicit 'use this when...' statement, no exclusion of the search/reviews siblings, and no prerequisites. Adequate but leaves routing to inference.

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