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

No annotations are provided, so the description carries the full burden. It discloses one behavioral trait: 'You will be added as the project owner.' However, it does not mention any side effects, permissions required, or post-creation state beyond ownership. This is a useful but limited disclosure.

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 two sentences: the first defines the core action, the second adds a relevant outcome. It is front-loaded and every word earns its place with zero redundancy.

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?

For a simple create operation with only two parameters and no output schema, the description is sufficiently complete. It identifies the resource and the side effect (ownership). It could mention that the project is created immediately or any required prerequisites, but given the low complexity, the current description is adequate.

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 100%, with both 'name' and 'description' already described accurately in the input schema. The description adds no additional meaning about the parameters, such as naming constraints or uniqueness, so it does not elevate beyond the baseline.

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 action ('Create a new project') and the resource ('project') with a specific context ('in your organization'). It distinguishes itself from sibling tools like 'create_task' and 'create_team' by focusing on projects. The added detail about becoming the project owner further clarifies the purpose.

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 implies the tool is for creating new projects but does not explicitly state when to use it versus alternatives like 'update_project' or 'delete_project'. There are no exclusions or alternative guidance, though the verb 'create' for a project is fairly unambiguous.

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