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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered structurally. The description adds useful content disclosure by naming exactly what data comes back (stored shipping-policy summary, catalog size, offer timestamps), but says nothing about behavior for unknown/unverified dealer IDs, whether 'verified' filters results, or freshness of the aggregates.

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 sentence, zero filler, front-loaded with the core action and then the payload. Every clause earns its place by naming a distinct returned datum.

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 carries the burden of describing return values, and it does so by listing the main fields. For a one-parameter read tool that is nearly sufficient; only failure behavior (invalid or unverified dealerId) and the meaning of 'current offer' timestamps are left unstated.

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 dealerId property already documents accepted formats with examples ('jm-bullion', 'JM Bullion', 'jmbullion.com'), so the description adds nothing on parameter meaning. The single mention of 'a verified bullion dealer' is the only hint that the identifier must resolve to a verified entity. 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?

Specific verb ('Get') plus specific resource ('a verified bullion dealer's public profile') and an enumeration of the returned fields (shipping-policy summary, catalog size, offer timestamps). It is clearly a single-entity lookup, which distinguishes it implicitly from list_verified_dealers and compare_product_dealers, though no sibling is named explicitly.

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 agent can infer it should call this when it needs profile/aggregate data for one known dealer, and the required dealerId reinforces the single-entity scope. There is no explicit when-to-use, when-not-to-use, or pointer to alternatives such as list_verified_dealers for enumeration or get_dealer_price_position for pricing context.

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