get_latest_traces

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

The description adds one behavioral detail: that timestamps are accepted in multiple units and normalized to microseconds. However, it does not disclose other important traits like read-only nature, authentication needs, or rate limits, which are not covered by annotations (none provided).

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?

Two sentences with front-loaded purpose. Every word earns its place. No redundancy or unnecessary detail.

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?

Despite having an output schema, the description fails to explain key parameters like pagination (offset/size), filtering (filter_query), timeout, and raw flag. The tool has 8 params and 3 required; the description covers only the timestamp normalization detail, leaving significant 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?

Schema description coverage is 0%, so the description must compensate. It only explains the timestamp format for start_time and end_time, but omits semantics for stream_name, size, offset, filter_query, timeout, and include_raw. Most parameters remain unexplained.

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 action ('Get the latest trace data') and the resource ('trace stream'). It distinguishes the tool from siblings like search_logs or search_around by targeting trace data specifically.

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 on when to use this tool versus alternatives. No mention of prerequisites, context, or exclusions. The description is silent on decision-making for the agent.

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