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

Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds only that the project is created empty, but says nothing about duplicate-name behavior, permissions/auth needs, or what identifies the new project afterward.

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?

One short, front-loaded sentence with no wasted words, but this is under-specification rather than effective conciseness. The brevity leaves obvious questions unanswered.

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?

No output schema exists, so the description should explain what a caller gets back (e.g., a project id) and how to proceed after creation. It provides none of that, and with a mutation tool plus an undocumented parameter this leaves real gaps for an agent.

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 single parameter `name` is documented only as a bare string type. The description does not explain what the name is used for, whether it must be unique, or any format constraints, so it fails to compensate for the coverage gap.

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?

"Create an empty project" gives a verb and resource, but it is essentially a restatement of the tool name/title. The only added information is the word "empty", which hints that no media or timeline is pre-populated, but the scope of "project" is never defined.

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 versus the many sibling tools (list_projects, show_projects, project_status, start_recipe). An agent must infer that this is the entry point for creating a new project container rather than opening an existing one.

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