get_public_store_details

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

No annotations are provided, so the description carries the full burden. 'Retrieves' implies a read-only, public (likely unauthenticated) operation, and the enumerated return fields give a useful preview of what comes back. It does not address behavior for a nonexistent subdomain, rate limits, or whether private fields are excluded.

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 with no filler; the resource and the scoping parameter both appear immediately. Slightly over-enumerated on returned fields, but nothing is wasted.

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 one-parameter, non-nested read tool with no output schema, the description is close to sufficient: it covers what is fetched and what the parameter identifies. Only edge-case behavior (invalid/nonexistent subdomain) is unaddressed, which is a minor gap at this complexity level.

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 schema already gives a concrete format example ('freshbakery' for freshbakery.blockmag.com). The description only restates that the parameter identifies a 'specific BlockMag store subdomain', adding no constraint or normalization detail beyond 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 verb ('Retrieves') and a concrete resource set (storefront details, contact info, currency, featured catalog items) scoped to a BlockMag store subdomain. An agent can distinguish it from search_public_stores, which locates stores rather than returning one store's details, though the description never names that sibling 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?

The phrase 'for a specific BlockMag store subdomain' implies you must already know the subdomain, which implicitly separates it from search_public_stores. However, there is no explicit when-to-use, when-not-to-use, or named alternative, so the routing must be inferred.

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