get_topic_metrics

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

With no annotations, the description should disclose behavioral traits. It does not mention if the tool is read-only, safe, or any side effects. The description adds no behavioral context beyond the minimal 'get metrics'.

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 very short (one sentence), which is concise but under-specified. It is front-loaded but does not contain enough information to be useful. It could add more detail without being overly verbose.

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 (4 parameters, many siblings, no annotations, output schema exists), the description is insufficient. It does not explain what metrics are returned, how time range works, or differentiate from similar tools. The output schema is present but not referenced.

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 description must explain parameter meaning. The description does not mention any of the four parameters (topic_name, duration, from_time, to_time). No information about format, units, or behavior of time parameters is provided.

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 says 'Get metrics for a specific topic' which is a verb+resource, but it doesn't specify what kind of metrics (e.g., throughput, latency) or how it differs from similar sibling tools like get_topic_info or get_topic_metrics variants. The purpose is clear but vague and lacks distinction.

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 provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, context, or when not to use it. There are many similar tools in the sibling list, and no comparison is made.

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