builds_app_encryption_declaration_get_to_one_relationship

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. It does not explain that a 'relationship' endpoint returns linkage/identifier data rather than the full resource, nor mentions auth requirements, response shape, or error behavior.

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?

It is short, but not efficient: it duplicates the identical URL string in parentheses with no added information, so a full half of the text is pure redundancy rather than front-loaded value.

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 relationship endpoint with no annotations and no output schema, the description should at minimum explain the relationship payload semantics and how it differs from the *_related sibling. None of that is present, leaving the agent under-informed.

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% and the single 'id' parameter is documented in the schema as 'the id of the requested resource'. The description adds no syntax or scoping detail beyond that, so the baseline of 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 is just the HTTP path restated twice in parentheses — it adds no prose explaining what the tool does. The name already encodes 'GET the appEncryptionDeclaration relationship of a build', so this is effectively a tautology rather than a clarification, and it does nothing to separate it from the sibling builds_app_encryption_declaration_get_to_one_related.

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 endpoint versus the nearly identical siblings (the *_get_to_one_related variant, which returns the full resource, or the *_update_to_one_relationship mutation). The agent is left to infer the relationship-vs-related distinction entirely from the tool name.

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