get_space_members

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

No annotations are provided, so the description carries full burden for behavioral disclosure. It's a read-type operation but the description doesn't state what happens for invalid space_ids, whether pagination applies (important since it returns 'all' members which could be large), or what the return format looks like. For a retrieval tool with no annotation coverage, this is thin.

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 sentence with zero wasted words. It states exactly what the tool does. Nothing to trim.

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?

For a single-parameter retrieval tool with no annotations and no output schema, the description is minimal but arguably sufficient. However, it doesn't clarify whether 'all' means paginated results, whether members include guests, or how the response is structured. Given the many member-related sibling tools, more context distinguishing space-level membership would improve completeness.

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%—the single parameter space_id is described as 'The space ID' in the schema. The description adds no additional meaning beyond what the schema already documents. Baseline 3 is appropriate since the schema already handles parameter documentation.

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 "Get all members of a space" uses a specific verb (get) and resource (members of a space). It clearly indicates the return is a collection of all members. It doesn't explicitly distinguish from sibling tools like get_workspace_members, get_list_members, or get_task_members, but the resource scoping (space) is clear.

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 is provided on when to use this tool versus siblings like get_workspace_members, get_list_members, or get_task_members. Given many member-related sibling tools exist, this is a notable gap—an agent could confuse which level (space vs workspace vs list vs task) applies.

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