functions_create_namespace

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

The description adds one behavioral detail: the namespace is tagged 'created_by=scaleway-mcp' for safe deletion. However, with no annotations provided, the description carries the full burden for behavioral disclosure, and it fails to mention other important behaviors like idempotency, error states, or quota implications.

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 extremely concise with two sentences. Every sentence adds value: the first states the action, the second adds a key behavioral detail. There is no wasted text.

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 the tool has 5 parameters and an output schema, the description is minimal. It lacks context about what the output represents, any regional considerations, or how the required name parameter should be chosen. The description is adequate for a simple creation tool but not comprehensive.

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 input schema has 100% description coverage, so the baseline is 3. The description does not add any parameter-specific information beyond what is in the schema; it only mentions the tagging behavior, not parameter details.

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 resource ('Serverless Functions namespace'), which is specific. However, it does not explicitly differentiate from sibling tools like containers_create_namespace or registry_create_namespace, though the context of 'Serverless Functions' provides some differentiation.

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 provides no guidance on when to use this tool versus alternatives, nor any conditions or prerequisites. It is purely functional with no usage context.

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