get_organization_members

Retrieve organization members from a Trello workspace. Identify who belongs to a team for effective access management and collaboration.

Instructions

Get members of an organization. Use this to see who belongs to a workspace.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
fieldsNoSpecific fields to include in the response. Overrides detailLevel. Use dot notation for nested fields (e.g., 'prefs.permissionLevel')
maxItemsNoMaximum number of items to return for list operations. Helps reduce response size for large datasets
summarizeNoReturn summary information instead of full data for list operations (e.g., '50 cards' instead of full card array)
detailLevelNoResponse detail level. 'minimal' returns only essential fields, 'standard' returns commonly used fields, 'detailed' returns most fields, 'full' returns all fields (default varies by operation type)
organizationIdYesID of the organization
Behavior2/5

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

With no annotations provided, the description must disclose behavioral traits, but it only states 'Get members' without any additional context. It does not mention whether the call requires specific permissions, how pagination works, or what the response structure contains. The description adds minimal behavioral insight beyond the name and title.

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

Conciseness5/5

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

The description is extremely concise, consisting of two short sentences that say exactly what the tool does and when to use it. There is no redundant information, and the structure is front-loaded with the core purpose. It earns a high score for directness and economy of words.

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?

For a straightforward read operation with comprehensive schema coverage, the description is minimally adequate. However, it lacks an output schema, so the agent must infer the return format, and the description does not elaborate on what fields or member details are included. The guidance provided is sufficient for basic use but leaves some ambiguity about the response's richness.

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 all parameters are fully described in the input schema. The description itself adds no parameter-level detail, such as the meaning of organizationId or the effects of fields/detailLevel. This aligns with the baseline of 3 for high schema coverage, as the schema handles parameter semantics.

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 clearly states the tool's purpose: 'Get members of an organization.' It specifies the resource (members) and the scope (organization/workspace), and the phrase 'Use this to see who belongs to a workspace' reinforces the purpose. While it does not explicitly differentiate from siblings like get_board_members or search_members, the distinction is evident from the resource named.

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

Usage Guidelines4/5

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

The description provides clear context for when to use this tool: 'Use this to see who belongs to a workspace.' This is a direct usage guideline, though it lacks an explicit 'when not to use' or mention of alternatives such as get_board_members for board-specific members. The context is unambiguous for a simple read operation.

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