gangtise_announcement_hk_download

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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It only states 'download HK stock announcement file', which implies a read operation but does not describe whether authentication is required, what file format is returned, or any rate limits. The description is insufficient for an agent to understand side effects or constraints.

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 actual tool description is a single short sentence, which is concise. However, a large date context note ('[当前日期 2026-05-27...]') is included, which is irrelevant to the tool's purpose and may confuse the agent. Without that note, the description would be well-structured. As is, it is cluttered.

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 simplicity (1 parameter, no output schema), the description is minimally complete. It tells what the tool does but lacks details on output format (e.g., binary file vs URL), usage prerequisites, and how it fits with sibling tools. The agent may need to guess or rely on naming conventions.

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?

Parameter coverage is 100% with a single required parameter. The schema description '公告 ID，来自 gangtise_announcement_hk_list' adds meaningful context by specifying the source of the ID. The tool description itself does not elaborate on the parameter, but the schema description compensates. Baseline 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 '下载港股公告文件' clearly states the tool downloads Hong Kong stock announcement files. The required parameter 'announcementId' is linked to gangtise_announcement_hk_list in its description, distinguishing this tool from siblings like gangtise_announcement_download (general) and gangtise_announcement_hk_list (list). The purpose is specific and actionable.

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 explicit usage guidelines are provided. The description does not state when to use this tool over alternatives such as gangtise_announcement_download or gangtise_research_download. The parameter description hints at obtaining the ID from gangtise_announcement_hk_list, but this is not framed as a prerequisite or guideline. The date context note is irrelevant to tool selection.

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