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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states nothing about what the mutation does to existing build relationships (additive vs. replace), permission/auth requirements, or reversibility. Only the body schema reference hints at the payload shape.

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 brief and front-loads the endpoint, but it redundantly repeats the identical path twice in parentheses, which earns no place. Otherwise it is terse without excessive padding.

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 mutation tool with no annotations, no output schema, and a nested JSON:API body, the description is far too thin. It omits any explanation of the operation's effect, side effects, or how the body maps to builds, leaving significant gaps an agent would need filled.

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 both the id and body parameters are already documented in the schema. The description's pointer to components.schemas.BetaGroupBuildsLinkagesRequest merely repeats the schema's own description, adding no new meaning. Baseline 3 applies.

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 gives the HTTP verb and endpoint path (POST /v1/betaGroups/{id}/relationships/builds), which implies adding builds to a beta group's builds relationship. However, it never states the operation in plain language and simply mirrors the tool name and URL. It offers no differentiation from the sibling get/delete variants (beta_groups_builds_get/delete_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.

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 the get or delete relationship siblings, nor any prerequisites or context. The description only restates the endpoint, leaving the agent to infer usage entirely.

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