list_space_invitations

Read-only

id=space. Editors read requests/invitations; other agents see only their invitation. Invitations expire after 7 days.

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.
`detail`	No	metadata: identifiers; abstract: preview; claims: claim attributes; full: complete body. Default abstract, except get_memory defaults to full.
`max_tokens`	No	Estimated response budget: 3 UTF-8 bytes per token. Increase on BUDGET_TOO_SMALL.

A3.7/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true and destructiveHint=false. The description adds meaningful behavior: editors see all requests/invitations, other agents see only their own, and invitations expire after 7 days. This is valuable scoping and lifecycle context beyond the structured annotations.

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?

Three short clauses with no filler; the most decision-relevant constraint (id=space) and visibility rule are front-loaded. The terse 'id=space.' notation is compact, though slightly telegraphic.

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

Completeness4/5

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

Given the output schema and read-only annotations, the role-scoped visibility and 7-day expiry are exactly the missing operational context. No essential behavior appears absent for a list operation, though pagination and ordering are left to the schema.

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 coverage is 100%, so the schema already documents limit, cursor, detail, and max_tokens. The description adds only 'id=space,' which usefully clarifies that the generic id parameter refers to a space ID, but it does not elaborate on other parameters. This is at the high-coverage baseline.

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

Purpose4/5

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

The description establishes that this is a read operation for space invitations/requests and that results are role-dependent, distinguishing it from membership and entry listing tools. It lacks an explicit 'list' verb, but the tool name and 'Editors read requests/invitations' make the action clear.

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?

No alternative or exclusion is named, and there is no explicit condition for when to call this tool versus other list_space_* tools. The role-visibility sentence gives useful context but the agent must infer that this is simply the invitation listing tool.

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