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

With no annotations, the description carries the full burden and does well: it declares read-only behavior, rules out ordering ('cannot place orders'), and discloses what comes back (product details and product-page links). It stops short of covering match behavior (exact vs fuzzy), result ordering, or what an empty result means, which matters for a search tool.

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 sentences, front-loaded with the search scope before the sibling routing hint. No repetition of schema fields and no filler.

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 two-parameter read-only search with no output schema, the definition covers scope, searchable facets, return contents, and the escalation path to get_product. Nothing essential to invoking it correctly is missing.

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 coverage is 100%, so the baseline is 3, but the description adds real meaning by enumerating what the free-text query can target (product name, lure type, color, size, fishing use) rather than only mirroring the schema's single example.

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 ('Find') plus a precisely scoped resource ('public Family Fishin tackle') and an enumeration of the searchable facets. It also separates itself from the sibling get_product by stating the latter is for full options and availability.

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?

Explicitly routes the agent: use this for discovery by name/lure/color/size/use, and call get_product when full options and current availability are needed. The 'public' qualifier also implies private/unpublished items are out of scope, so the when-not condition is inferable from stated scope.

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