passgage_create_branch_group

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

With no annotations and a description that merely restates the tool's name, there is zero disclosure about behavioral traits. The agent is not informed about required data structure, idempotency, permissions, or response behavior. The description adds no value beyond the tool name.

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 to the point of being a restatement of the tool name. While brevity is valued, this sacrifices essential information and is better characterized as missing specification rather than true conciseness.

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?

The tool has a complex input (an unrestricted object), no output schema, no annotations, and a description that says nothing about data shape, return values, or error handling. For a create operation with significant ambiguity, this is severely incomplete and would prevent correct invocation.

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?

Although schema description coverage is 100%, the only parameter 'data' is described as 'The data for creating the branch_group'—a tautology. It provides no structural information, required fields, or examples. The tool description also lacks parameter context, leaving the agent completely in the dark about what to pass.

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 'Create a new branch_group' explicitly states the action and resource, clearly distinguishing it from sibling operations like update, delete, get, and list for branch groups. The verb and noun are specific and unambiguous.

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 alternatives. It does not mention prerequisites (e.g., existing parent resources), when to prefer update over create, or any exclusion criteria. The description is purely declarative with no selection assistance.

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