list_announcement_notify_levels

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

With no annotations, the description must carry the transparency burden. It discloses the HTTP method (GET), implying a read-only operation, and the resource being fetched. However, it does not mention any authentication requirements, return format, or potential side effects. For a simple zero-parameter list, this is adequate but not rich.

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 sentence containing both the human-readable purpose and the technical endpoint. It is concise, direct, and free of unnecessary words or repetition.

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 (no parameters, no output schema), the description provides adequate context: it identifies the resource and the action. The endpoint adds technical specificity. It could be improved by clarifying the return structure, but this is not essential for a simple list. The existence of similar sibling tools is not mentioned, but the 'levels' qualifier mitigates ambiguity.

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 tool has zero parameters, so schema description coverage is trivially 100%. The baseline for zero parameters is 4, and the description does not need to add parameter details. It correctly omits any parameter information.

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's function: '獲取公告通知等級列表' (get announcement notification level list) and includes the specific HTTP endpoint. It distinguishes from siblings like list_announcement_notify_types and list_announcement_notify_scopes by specifying 'levels' as the resource.

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?

No guidance is provided on when to use this tool compared to alternatives. There is no mention of context, prerequisites, or exclusion criteria. Sibling tools with similar names (types, scopes) are not referenced, leaving the agent without differentiation cues.

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