Create Claude Project

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

With no annotations, the description must disclose behavioral traits. It only states what is created but omits whether the tool overwrites existing files, requires authentication, or has side effects. No information on success/failure behavior or limitations.

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 sentence that is clear and to the point. It is appropriately short but could be slightly expanded to include key behavioral traits without becoming verbose.

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?

Despite having an output schema, the description does not mention what the tool returns (e.g., project path or confirmation). For a tool with 7 parameters and a required set, the description should at least hint at the output or success criteria. It is minimally complete but lacks essential context.

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%, so the baseline is 3. The tool description adds no extra meaning to parameters; it only references templates. The schema already describes each parameter adequately, so no significant addition from the description.

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') and the specific resource ('Claude.ai project folder') with explicit deliverables ('INSTRUCTIONS.xml and PURPOSE.md templates'). It distinguishes from siblings like 'add_project' and 'scaffold_project' by specifying the folder and template 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?

No guidance is provided on when to use this tool versus alternatives like 'add_project' or 'scaffold_project'. The description does not mention prerequisites, when to choose this over similar tools, or what not to use it for.

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