List workspaces

list_workspaces

Read-only

List the workspaces (shared team spaces) the account belongs to, as { id, name, role, memberCount } entries. role is the caller's role in that workspace (owner / admin / editor / viewer) — only owner/admin/editor can add projects. The id is the workspaceId argument of create_project, move_project_to_workspace and list_projects; name is the label people see in the workspace switcher. Returns an empty list when the account has no email (workspace membership is email-based, so a keyless/dev identity sees none).

Tool call template

This tool declares no required parameters. Add optional parameters from the input schema as needed.

A4.5/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds genuine value beyond that: the role enumeration (owner/admin/editor/viewer), the permission implication (only owner/admin/editor can add projects), and the empty-list edge case for keyless/dev identities. Minor gap: no statement about ordering or pagination, though openWorldHint=false implies a bounded set.

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?

Three tight sentences, front-loaded with what is listed and what comes back. Every clause carries distinct information: the entry shape, role/permission meaning, the id cross-reference, and the empty-list condition. No restatement of the title or annotations.

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

Completeness5/5

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

With an output schema present, return values need not be re-explained, yet the description still adds the role enum semantics, sibling id mapping, and the empty-list failure mode. Nothing an agent needs in order to call this zero-arg read tool correctly is missing.

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

Parameters4/5

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

The tool takes zero parameters, so the baseline of 4 applies. The description instead documents output field semantics (role values, id mapping) rather than parameters, which is above the floor even though an output schema already exists.

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

Purpose5/5

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

States a specific verb and resource ('List the workspaces (shared team spaces) the account belongs to') and even enumerates the returned shape {id, name, role, memberCount}. An agent can distinguish this from siblings like list_projects or create_workspace without opening any schema.

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?

Names the consuming siblings explicitly — the returned `id` is the workspaceId argument of create_project, move_project_to_workspace and list_projects — which tells an agent when this tool is a prerequisite. It stops short of an explicit when-not clause or a direct comparison against list_projects.

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