Infer remote schemas

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

Annotations already declare readOnlyHint and idempotentHint, so the safety profile is covered. The description adds the notion of an analysis operation, but it does not disclose any further behavioral traits such as performance implications, data source requirements, or side effects. With annotations present, this is acceptable but not enriched.

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 a single, focused sentence that starts with the core action 'Cluster'. It avoids redundancy, contains no filler, and every word contributes to understanding. This is exemplary conciseness.

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 output schema, the description should explain return values; it does just enough by naming 'structural argument signatures with frequency and sequence ranges'. However, it omits details about prerequisites (e.g., how calls were captured), edge cases, or result format, making completeness moderate for an analysis tool.

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 50%, with only clientId described. The description does not mention parameters at all, failing to compensate for the undocumented 'limit' parameter. It provides no insight into how limit affects the clustering or why a user might adjust it, so the value added is minimal.

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 ('Cluster') and the resource ('captured remote calls') while specifying the output ('structural argument signatures with frequency and sequence ranges'). This distinguishes it from sibling tools like get_remote_events or capture_re_snapshot by focusing on schema inference from recorded calls.

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 implies usage when captured remote calls are available, but it does not explicitly state when to choose this tool over alternatives or provide exclusions. While the context is somewhat clear, it lacks explicit guidance on prerequisites or comparison to siblings, so it falls short of a 4.

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