create_namespace

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

Discloses that resources are isolated across namespaces, a key behavioral trait. No annotations provided, so description carries full burden. Lacks details on auth requirements, idempotency, or error behavior.

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?

Three concise sentences with no waste. Front-loaded with the primary action and key context.

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 no output schema, description does not explain return value. Also lacks error handling info (e.g., duplicate namespace behavior). Provides isolation context but is incomplete for a creation 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?

Schema covers both parameters with examples and descriptions (100% coverage). The tool description adds context about using 'default', but does not significantly enhance parameter meaning beyond the schema.

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?

Explicitly states 'Create a new namespace' with a clear verb and resource. Differentiates from siblings by describing isolation property, and gives concrete guidance on using 'default' namespace.

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?

Provides explicit advice to use 'default' unless isolation is needed, indicating when to use. However, does not explicitly mention when not to use or list alternatives beyond the context of siblings.

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