doc_builder_add_collaborator

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

With no annotations, the description bears full responsibility for disclosing behavioral traits. It fails to mention whether adding a collaborator sends an invitation, what the default role implies, or if the operation is idempotent. Critical behavioral details are absent.

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 a single short sentence, but it is under-specified for a tool with four parameters. While concise in word count, it sacrifices necessary detail, failing to earn its place with substantive information beyond the tool name.

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?

Despite the presence of an output schema, the description provides no context about return values, side effects, or any behavior beyond the basic action. Combined with the lack of annotations and parameter explanations, the description is grossly incomplete for effective tool use.

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 0%, and the description adds no explanation for any parameter. It does not clarify the difference between email and user_id, the meaning of session_id, or valid values for role. The agent is left to guess from parameter names alone.

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 clearly states the verb 'add' and the resource 'collaborator to a document builder session,' making the purpose immediately understandable. It is specific enough to distinguish from similar tools like code_workspace_add_collaborator due to the 'doc_builder' prefix, but it does not explicitly differentiate itself.

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?

No usage guidance is provided. The description does not indicate when to use this tool versus alternatives like doc_builder_collaboration or when not to use it. There is no mention of prerequisites or contextual cues.

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