containers_create_namespace

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

The description discloses that the tool tags the namespace with 'created_by=scaleway-mcp' for safe deletion, which adds behavioral context beyond the schema. However, it does not mention error handling or idempotency, and annotations are absent, so the description carries the full burden.

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 consists of two efficient sentences: the first states the primary purpose, the second adds a key behavioral detail. No redundant information.

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?

With no required parameters and an output schema, the description is largely sufficient. It covers purpose and a critical side-effect (mandatory tagging). However, it could mention the automatic name generation for omitted 'name', though this is documented in the schema.

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?

The description explains that the tool always adds a 'created_by=scaleway-mcp' tag, which clarifies the interaction with the optional 'tags' parameter. This adds meaning beyond the schema's description of tags.

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 'Create a Serverless Containers namespace', specifying the exact verb and resource. It distinguishes from sibling tools like containers_create_container by explicitly targeting namespace 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?

The description does not explicitly state when to use this tool versus alternatives. While it's implied that namespaces are prerequisites for containers, there is no direct guidance on prerequisites or exclusions.

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