create_space

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

With no annotations provided, the description carries full burden for behavioral disclosure. 'Create a new space' implies a mutation/write operation, but the description doesn't mention required permissions, whether this operation is idempotent, what happens on failure, or what the response contains. For a creation tool with 11 parameters and no annotation coverage, this is a significant gap in behavioral context.

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 maximally concise at just three words. It's front-loaded with the essential action and resource, with zero wasted words. Every sentence (in this case, the single phrase) earns its place by communicating the core purpose efficiently.

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 complexity (11 parameters, creation operation) and absence of both annotations and output schema, the description is insufficiently complete. It doesn't explain what a 'space' is conceptually, what happens after creation, or provide any behavioral context. For a tool with this level of complexity and no structured safety/behavior annotations, the description should do more heavy lifting.

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 all parameters are documented in the schema. The description adds no additional parameter information beyond what's already in the structured schema. According to scoring rules, when schema coverage is high (>80%), the baseline is 3 even with no parameter info in 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 verb ('Create') and resource ('a new space'), making the purpose immediately understandable. However, it doesn't differentiate this tool from sibling creation tools like create_doc, create_folder, or create_task, which all follow the same 'Create a new X' pattern without explaining what distinguishes a 'space' from those other resources.

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. There's no mention of prerequisites, when to choose create_space over create_folder or create_doc, or any contextual constraints. The agent must infer usage from the tool name alone.

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