bitwarden_create_group

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

With no annotations, the description carries full burden for behavioral transparency. It reveals the returned id and the follow-up invite workflow, but omits permissions required, potential errors (e.g., duplicate names), or reversibility. This is a significant gap for a mutating tool.

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 appropriately sized with a one-sentence purpose, a useful workflow note, and a structured Args list. It is front-loaded and each sentence earns its place, though the Args section is slightly verbose relative to the schema.

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?

Given the simple create operation and presence of an output schema, the description covers the core purpose, parameter meanings, and the follow-up step. It lacks guidance on prerequisites or failure modes, but is largely complete for a straightforward tool.

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?

All three parameters are explicitly explained: name is 'Name of the group to create,' access_all is described as granting access to all collections with a default, and external_id is contextualized as an IdP sync identifier. This adds meaning well beyond the bare schema titles.

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 opens with 'Create a new vault group in the Bitwarden organization,' using a specific verb and resource. It clearly distinguishes from member-focused sibling tools (e.g., invite_member, list_member_groups) by focusing on group creation.

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?

The description provides a workflow hint about using the returned id with bitwarden_update_member_groups, but it does not explicitly state when to use this tool over alternatives or mention any exclusions. Usage is implied by the 'create' action rather than explicitly guided.

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