C2.7/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds that the response includes member/collection details, which is useful beyond annotations, but it does not disclose org scoping, pagination, or permission requirements.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single short phrase with no wasted words and is front-loaded. However, it is under-specified rather than appropriately concise for a tool with four parameters and no schema descriptions.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with four undocumented parameters, a required org_id, and no output schema, the description is too thin. It omits how the org_id scopes the listing and what the generic form/params/json_body parameters are for, leaving the agent unable to invoke it confidently beyond the required field.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% across four parameters, including the required org_id plus generic form, params, and json_body fields. The description provides no parameter meaning at all, so it does not compensate for the entirely undocumented schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource ('List groups') and adds that results include member/collection details, which helps distinguish it from a plain group list. However, it does not explicitly name or contrast with siblings such as get_groups, get_group_details, or get_group_members.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this tool versus alternatives like get_groups, get_group_details, or get_group_members. The only implied usage is that it lists groups, but no exclusions, prerequisites, or selection criteria are provided.

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