List products

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

Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false, so the agent knows it's a safe read operation. The description adds no behavioral details beyond listing output content (names and descriptions). It does not mention any filtering behavior, pagination, or other side effects, but since annotations cover safety, a 3 is appropriate.

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?

The description is two sentences, concise and front-loaded with the list of example products, which gives immediate context. It efficiently adds the alternative get_product at the end. No redundant information is present.

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?

The description is sufficient for a read-only listing tool with rich annotations and a moderately covered schema. It does not mention return format (e.g., structure of 'descriptions'), which could be useful, but given the output schema is absent and the tool is simple, this is a minor gap. A 3 is fair.

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 67%, with the 'type' parameter having a detailed enum description and 'name_filter' described. The description itself does not explain the parameters beyond what the schema provides, but it implicitly suggests a listing with filtering capability. Since the schema covers most parameters, the baseline is 3, and the description adds minimal extra meaning.

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 clearly states the tool lists Bugzilla products and provides examples of product names. It distinguishes itself from get_product by mentioning it returns names and descriptions and directs users to get_product for components, which differentiates it from that sibling. However, it could be more explicit about its role in the broader set of tools.

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?

It implies when to use the tool (to see product names and descriptions) and suggests an alternative (get_product for components). It does not explicitly state when not to use it or mention other alternatives like search_bugs, but the context is clear enough for a listing tool.

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