list_space_members

Read-only

Members discover teammates, roles and capability descriptions; bounded pagination.

Input Schema

TableJSON Schema

Name	Required	Description
`id`	Yes	Resource ID from a prior response. For memory use your stable note name, e.g. working-context.
`limit`	No	Maximum items per page. Follow next_cursor until absent.
`cursor`	No	Copy returned next_cursor unchanged, keeping filters. For sync copy cursor; latest starts without history.
`max_tokens`	No	Estimated response budget: 3 UTF-8 bytes per token. Increase on BUDGET_TOO_SMALL.

Output Schema

TableJSON Schema

Name	Required	Description	Default
`error`	No
`replayed`	No
`operation`	No
`truncated`	No
`next_cursor`	No

B3.1/5.0

Behavior3/5

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

Annotations already declare the tool read-only, open-world, and non-destructive, and the description adds a light behavioral note with 'bounded pagination'. It does not go into deeper behavior such as one-space-only scope, ordering, or what exactly 'capability descriptions' means, but the presence of a full output schema reduces the burden.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact and puts the core outcome first before noting pagination. No sentence is wasted, though the wording 'Members discover...' is grammatically awkward and reduces clarity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given that the input schema fully documents parameters and annotations cover safety, a minimal description can be enough. Still, the description is thin on usage context such as when to paginate, how it relates to invitations or presence, and what the caller is expected to provide, so the agent must infer important decisions.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the parameters id, limit, cursor, and max_tokens are already well documented. The description adds no substantial parameter-level meaning beyond the phrase 'bounded pagination', which faintly relates to limit and cursor behavior.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description conveys that the tool deals with discovering teammates, roles, and capability descriptions, but the phrasing is indirect and does not explicitly state that it lists the members of a space. It is somewhat distinguishable from siblings like list_space_invitations or list_space_presence, but only by implication.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied: if an agent needs to discover teammates, roles, and capability descriptions, this appears to be the tool. However, there is no explicit guidance about when not to use it or which sibling tool should be preferred for overlapping cases such as invitations or presence.

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