show_gitee_humming_card

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

The description explains that the tool returns a ToolResult with a plain text fallback and a structured PrefabApp card, which adds transparency about the return format. However, it does not mention any behavioral traits like rate limits, authentication needs, or side effects. Since no annotations are provided, the description bears the full burden, but it leaves gaps about behavior beyond output format.

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 uses a front-loaded purpose statement, but includes a rationale section that is overly verbose (e.g., 'Status/list tools MUST ship a Prefab surface per fleet SOTA') which detracts from clarity. The example and return format are useful, but the rationale could be condensed or moved to development notes.

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 has only 2 optional parameters and no output schema, the description covers the purpose and return format reasonably well. However, it lacks details on what 'humming' means (e.g., trending repos, popular topics) and does not explain the 'translate' parameter. For a simple tool, it is mostly adequate but leaves minor gaps.

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 two parameters with defaults but no descriptions, resulting in 0% schema coverage. The description includes an example showing the 'limit' parameter, adding meaning that 'limit' controls the number of items. It does not explain the 'translate' parameter, but the contextual signal of a sibling 'gitee_translate' suggests its purpose. The description partially compensates for the schema gaps.

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 shows 'what is humming on Gitee right now as a rich in-chat card', giving a specific verb (show) and resource (humming status). It distinguishes itself from siblings like 'show_gitee_status_card' by focusing on trending/humming content rather than general status.

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 implies a primary use case (display trending Gitee content) and provides an example call, but does not explicitly state when to use this vs alternatives like 'gitee_explore' or 'show_gitee_status_card'. No exclusion criteria or context for choosing between siblings is given.

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