Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. '获取' (get) implies a read operation, but the description doesn't specify whether this requires authentication, has rate limits, returns structured data, or handles errors. For a tool with zero annotation coverage, this is a significant gap in behavioral context.
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 a single, efficient phrase ('获取事件的详情') with zero wasted words. It's appropriately sized for a simple retrieval tool and front-loads the core purpose immediately.
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?
Given the tool's simplicity (1 parameter, no output schema) and lack of annotations, the description is incomplete. It doesn't explain what 'event' refers to in this context (e.g., data events, workflow events), what details are returned, or any behavioral traits. For a tool named 'GetTopic' among many similar 'Get' siblings, more context is needed to guide proper usage.
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?
The input schema has 100% description coverage (TopicId is documented as '事件的ID' - event ID), so the schema already provides parameter meaning. The description doesn't add any additional semantic context beyond what's in the schema, such as format examples or constraints. With high schema coverage, the baseline score of 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?
The description '获取事件的详情' (Get event details) states a clear verb ('获取' - get) and resource ('事件的详情' - event details), providing a basic purpose. However, it doesn't distinguish this tool from other 'Get' siblings like GetAlertRule, GetCatalog, GetColumn, etc., which also retrieve details of different resources. The purpose is clear but lacks sibling differentiation.
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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing a TopicId), exclusions, or context for selecting this over other 'Get' tools. Without any usage context, the agent must infer based on the tool name alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
