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

With no annotations provided, the description carries the full burden. It clearly indicates this is a read operation ('List bugs'), but doesn't disclose behavioral traits like pagination behavior (implied by page/limit parameters), rate limits, authentication requirements, or what the return format looks like. It adds some context about the prerequisite but lacks comprehensive behavioral details.

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 efficiently structured in two sentences: the first states the purpose and usage context, the second provides the prerequisite. Every sentence adds value with no redundant information, and it's appropriately front-loaded with the core functionality.

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 list operation with 3 parameters and no output schema, the description provides adequate purpose and usage guidance but lacks details about return format, pagination behavior, or error conditions. The absence of annotations means the description should do more to cover behavioral aspects, though it successfully addresses the core use case and prerequisites.

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%, so the schema already fully documents all three parameters. The description adds minimal value beyond the schema by mentioning the product ID prerequisite, but doesn't provide additional semantic context about parameter usage or relationships. This meets the baseline for high schema coverage.

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 specific action ('List bugs') and resource ('for a specific product in ZenTao'), distinguishing it from sibling tools like zentao_bug_get (single bug) and zentao_bugs_mine (user-specific bugs). It provides both English and Chinese terminology for clarity.

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 description explicitly states when to use this tool ('when user asks to see/view/show bugs or wants to check issues for a product') and provides alternative phrasing in both English and Chinese. It also mentions a prerequisite ('Requires product ID which can be obtained from zentao_products_list') and implicitly distinguishes from siblings by focusing on product-specific listing.

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