D1.8/5.0
Behavior2/5

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

Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=true, and the description adds nothing further — no mention of required admin/owner privileges, whether the creator becomes an owner, billing/plan implications, or what happens on name collision. For a state-changing, open-world creation call this is a substantial gap, though not a contradiction.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Four words with nothing wasted, but this is under-specification rather than conciseness — there is no front-loaded content beyond the obvious restatement of the name.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

A three-parameter mutation tool with zero parameter documentation, no output schema, and no behavioral detail is completely inadequate; the description conveys nothing an agent needs in order to call it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

All three parameters are named generically ('form', 'params', 'json_body') with 0% schema description coverage, and the description says nothing about what any of them should contain. An agent has literally no signal about required payload shape for creating an organization.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose2/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description restates the tool name and title verbatim ('Create a new organization'), adding no differentiating information. Among siblings such as vaultwarden_post_organization, vaultwarden_organizations_post_api_key, and vaultwarden_get_organization, an agent has no way to tell which is the intended creation endpoint.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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 many other organization-related siblings, no prerequisite or permission context, and no exclusions. The agent must guess based on the name alone.

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