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

No annotations are provided, yet the description discloses no behavioral traits. It omits whether the tool requires authentication, what happens if the Space ID is invalid/expired, rate limits, or whether the data is real-time or cached.

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 a single, brief sentence with no redundant words. However, 'Give you' could be more professional/action-oriented (e.g., 'Retrieves'). It is appropriately front-loaded for its length.

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 lack of output schema, the description should explain what information is returned about a Space. It fails to do so. While the tool has only one parameter, the absence of behavioral context and return value description leaves significant gaps.

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 coverage is 100%, establishing a baseline of 3. However, the description adds no clarification about what the 'id' represents (Space ID vs. other ID types) or how to obtain it. The schema description only provides an example value without semantic context.

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 identifies the target resource (Spaces) but uses vague phrasing ('basic information') and a weak verb ('Give you'). While it distinguishes from siblings (tweets, users, communities), it fails to specify what specific data is returned (metadata, participants, status, etc.).

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?

No guidance provided on when to use this tool versus alternatives like search or discovery tools. No prerequisites (e.g., valid Space ID format) or error conditions are mentioned.

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