create_collector_group

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

Annotations already convey that this is a write operation (readOnlyHint=false). The description adds the permission requirement, which is useful context beyond the annotations. However, it does not disclose other behaviors like idempotency (idempotentHint=false), what happens on duplicate names, or whether it overwrites. Given annotations cover the safety profile, the description adds minimal but non-zero value.

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?

A single sentence that is immediately clear and front-loaded with the core purpose. No fluff or redundant information. Efficient and well-structured.

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?

For a simple create operation with only one required parameter, the description is adequate. However, it does not mention the response format or any side effects (e.g., whether the group is immediately usable). Given no output schema, the description could be more informative about what happens on success. It is minimally complete but lacks details that would help an agent anticipate behavior.

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 100%, so all parameters are already documented with names and types. The description adds no additional semantics about parameters, such as constraints or relationships. Baseline 3 is appropriate when the schema fully documents parameters.

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 'Create a collector group' – a specific verb and resource. It distinguishes from sibling get/update/delete_collector_group operations. The purpose is unambiguous.

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 vs. alternatives. The mention of 'requires write permission' is a prerequisite, not a usage context. It doesn't clarify, for instance, that this is for creating new groups rather than updating existing ones. No when-not-to-use or alternative tool references.

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