instrumentation_group_inspect

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

The annotations already indicate readOnlyHint=true, so the description does not need to restate that. However, the description adds no additional behavioral context, such as what happens if the name is invalid, or if data is truncated. It provides minimal added value beyond the annotations.

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 sentence, which is concise and front-loaded. However, it may be too brief; a slightly more informative sentence would be warranted without reducing 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?

Given the tool's simplicity (one required parameter, no output schema), the description still lacks completeness. It does not explain what the inspection produces (e.g., a list of hits, detailed logs) or how to interpret the results. The agent is left guessing about the output.

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 only parameter 'name' has no description in the schema (0% coverage). The description does not clarify what 'name' refers to (presumably the group name), nor does it explain acceptable values. The description fails to compensate for the missing schema documentation.

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 uses the verb 'Inspect' and specifies the resource 'grouped breakpoint hits and trace logs', making the tool's purpose clear. It implicitly distinguishes from siblings like 'instrumentation_group_clear' and 'instrumentation_group_create' by focusing on inspection rather than modification. However, it could more explicitly differentiate from other inspection tools.

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, such as get_trace_log or list_breakpoints. No prerequisites or exclusion criteria are mentioned. The description lacks any contextual usage advice.

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