Create Space

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

Annotations already convey that this is a mutation (readOnlyHint=false) and non-destructive (destructiveHint=false). The description adds the key format constraint and marks description as optional, but does not discuss failure behavior, idempotency, or side effects. It provides some context beyond annotations but not extensive.

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: one purpose sentence plus a compact args list. It front-loads the purpose and uses a clean format with no wasted words.

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?

This is a straightforward creation operation with only 3 parameters. The description covers purpose and all parameters, and annotations provide the safety profile. It does not mention return value or error cases, but these can be inferred from typical create semantics and the tool's simplicity.

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 schema provides no parameter descriptions (0% coverage), so the description compensates by explaining all three parameters: key format with example, name purpose, and description optionality/nullability. This significantly aids correct invocation, though it could include more details like length limits or character sets for name.

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 uses the specific verb 'Create' and resource 'Confluence space', clearly distinguishing it from sibling tools like create_page or create_space_property. The purpose is unambiguous and directly stated in the first sentence.

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 context of creating a space is clear, but the description does not explicitly mention when to use this tool versus alternatives like create_space_property. There are no exclusions or prerequisites noted, so it lacks explicit usage guidance beyond the obvious purpose.

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