ingest_stats

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

No annotations are provided, so the description carries full burden. It only states what the tool does ('获取 Ingest 统计信息') without disclosing behavioral traits like whether this is a read-only operation, what permissions are required, whether it affects system performance, what format the statistics are returned in, or any rate limits. For a statistical retrieval tool with zero annotation coverage, this is inadequate.

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 appropriately concise with two brief lines stating the purpose and parameter. There's no unnecessary verbiage, and the information is front-loaded. However, the structure could be slightly improved by using complete sentences rather than fragmented lines.

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 complexity (statistical retrieval tool), lack of annotations, no output schema, and minimal parameter documentation, the description is incomplete. It doesn't explain what 'Ingest statistics' encompass, what the return format looks like, or any prerequisites. For a tool that likely returns structured data about ingest pipelines or processors, this leaves significant gaps for an AI agent.

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 0%, so the schema provides no parameter documentation. The description adds minimal value by mentioning 'node_id: 节点 ID（可选）' (node_id: node ID (optional)), which explains the parameter's purpose and optionality. However, it doesn't specify what format the node ID should be in, what happens when omitted, or provide examples. With one parameter and 0% schema coverage, this partial compensation is insufficient.

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 states '获取 Ingest 统计信息' (Get Ingest statistics), which provides a basic verb+resource combination. However, it's vague about what specific statistics are retrieved and doesn't differentiate from sibling tools like 'index_stats' or 'nodes_stats' that also retrieve statistics. The purpose is understandable but lacks specificity.

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 about when to use this tool versus alternatives. With many sibling tools that retrieve various types of statistics (index_stats, nodes_stats, cluster_stats, etc.), the description offers no context about what makes 'ingest_stats' distinct or when it should be preferred over other statistical tools.

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