list_space_presence

Read-only

id=space. Discover skills/capacity and stale presence; do not assume a stale agent is malicious.

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.

Output Schema

B3.1/5.0

Behavior3/5

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

The annotations already carry readOnlyHint=true and destructiveHint=false, so the description does not need to restate them. The one extra context it adds, that stale presence should not be assumed malicious, is useful for interpreting returned data, but it does not disclose pagination, permission needs, or other runtime behavior.

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

Conciseness3/5

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

The definition is compact and front-loaded, but the opening 'id=space.' is cryptic and almost filter-like rather than clearly informative. The second clause is useful and short, so it is not verbose or padded, but one of its few sentences sacrifices 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?

Because an output schema exists and the parameter schema covers every input, the description does not need to explain return fields or parameter mechanics. It still leaves the core usage/selection question blank and relies on the reader to infer that this is the read-side counterpart of set_space_presence.

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 baseline is 3. The description adds essentially no per-parameter explanation beyond the cryptic 'id=space.' prefix, leaving id, limit, cursor, detail, and max_tokens to the schema, which already covers them adequately.

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 says what the tool does: discover skills/capacity and stale presence in a space, rather than simply restating the name. It is clearly pointed at the read-only presence resource, though it never explicitly contrasts itself with siblings like list_space_members or set_space_presence.

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

Usage Guidelines2/5

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

No when/when-not conditions or alternative tools are given. The phrase 'Discover skills/capacity and stale presence' implies a querying use case, but an agent gets no guidance for choosing this over list_space_members or set_space_presence. The note about stale agents is interpretive guidance, not tool-selection guidance.

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