Get Group List

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

Annotations already indicate read-only, non-destructive, and idempotent behavior, so the description's minimal text is acceptable. It adds clarity that it returns all groups, which is beyond the annotations. No contradiction, but it does not detail what is returned (e.g., list format), but given the simplicity, this is adequate.

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 extremely concise, consisting of a single sentence with no wasted words. It is appropriately short for a simple tool with no parameters, achieving high clarity.

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 that the tool is simple, has no parameters, no output schema, and annotations cover safety aspects, the description is nearly complete. However, it could mention that it returns a list of group names or IDs, but this is not critical for a listing tool with no parameters. The completeness is adequate but not outstanding.

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 tool has zero parameters, and the schema description coverage is 100% (empty schema). The description does not need to explain parameters. Baseline for zero params is 4, and the description is sufficient.

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 'Get all OBS groups' clearly states the action (get) and the resource (OBS groups), indicating a retrieval operation. However, it does not differentiate from similar sibling tools like 'obs-get-scene-list' or 'obs-get-scene-list', but the purpose is clear enough for selecting the tool.

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 does not explicitly state when to use this tool versus alternatives, but the name and description imply it is for listing groups. Given the large sibling set, there is no guidance on when to use it over 'obs-get-scene-list' or others, but the clear purpose provides implicit usage context.

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