group_capture_analysis

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

No annotations are provided, so the description must carry the burden of behavioral disclosure. It mentions 'lower token cost' as a benefit, which is useful, but does not clarify key behaviors such as whether the operation is read-only (likely), whether data is consumed or cached, or what the output structure contains. The description is too terse to provide adequate transparency for a complex analysis tool.

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 one sentence, which is concise and front-loads the primary action ('Group') and benefit ('inspect hot spots'). However, its brevity sacrifices necessary detail, making it more under-specification than optimal conciseness. It earns points for being short and focused.

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's high complexity (25 params, many filters and grouping options) and the lack of parameter descriptions, the description is incomplete. It provides no guidance on required parameters, preset semantics, or filter usage. The presence of an output schema helps but does not compensate for the absence of operational context.

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?

With 25 parameters and 0% schema description coverage, the description must compensate by explaining parameter usage, but it does not. The description only mentions the concepts of grouping and hot spots, leaving all parameters (e.g., 'group_by', 'preset', filters) and their relationships unexplained. This is a significant gap given the schema's lack of descriptions.

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 a clear verb and resource: 'Group analyzed traffic' to help the agent inspect hot spots, which conveys the core function. However, it does not differentiate from sibling tools like 'get_capture_analysis_stats' or 'query_recorded_traffic', which may also operate on analyzed traffic, leaving potential ambiguity.

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 gives a hint of when to use it ('so the agent can inspect hot spots') but provides no explicit guidance on when to prefer this over alternatives or when not to use it. It lacks mention of specific scenarios or exclusions, leaving the agent to infer usage from the tool name and schema.

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