D1.9/5.0
Behavior1/5

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: no auth requirements, no pagination behavior (despite a limit parameter), no read-only confirmation, no response shape. It is a bare route echo and leaves every behavioral question open.

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

Conciseness2/5

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

The description is short but not concise in the meaningful sense: it wastes its single sentence by repeating the same endpoint string twice with no added information, so no part of it earns its place.

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

Completeness1/5

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

With no output schema, no annotations, and a description that is only the raw route, an agent lacks everything needed to use this tool confidently: what the relationship payload contains, whether it is paginated, and how it differs from the plethora of sibling relationship endpoints.

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

Parameters3/5

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

Schema description coverage is 100%, with both parameters ('id' and 'limit') documented in the schema, so the description needs to add little. It adds nothing, which is the baseline case for a fully documented two-parameter schema.

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

Purpose2/5

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

The description only restates the HTTP route and duplicates it in parentheses, so it identifies the endpoint (betaGroups → builds relationship) without stating in words what the tool does. An agent must decode the path and the name suffix to guess 'list builds associated with a beta group', and it gets no help distinguishing this from siblings like beta_groups_builds_get_to_many_related or builds_beta_groups_create_to_many_relationship.

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 statement of when to use this tool versus the many sibling relationship endpoints (related vs relationship variants, create/delete variants). The route path at best implies 'fetch the relationship linkage', but no exclusion or alternative is named.

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