ListLogHistogram

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

With no annotations and no description of behavior beyond 'operation', the tool's side effects, return format, pagination, or auth requirements are entirely undisclosed. The agent has no information about what invoking this tool will do.

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 brief but under-specified. One sentence that repeats the tool name without adding substantive detail is not effective conciseness; it lacks essential information.

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?

With no annotations, no output schema, a nested body schema with undocumented properties, and no behavioral explanation, the description is far from complete for an agent to use this tool correctly.

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 description adds no parameter information. Although region and project_id have schema descriptions, the nested body object with seven properties has no explanations for fields like start_time, end_time, group_id, stream_id, key_word, is_iterative, or step_interval, and the description does not compensate for this gap.

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 merely restates the tool name as 'Huawei Cloud LTS operation ListLogHistogram' without stating what the tool does. It provides no verb, resource, or outcome, making it essentially a tautology.

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?

There is no guidance on when to use this tool, when not to use it, or how it differs from sibling tools like ListLogs or ListLogContext. The description gives no context for selection among alternatives.

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