List workspace members (admin session)

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety and openness are covered. The description adds only the 'admin session' permission hint and the raw GET path, saying nothing about pagination, result size, or response shape for what is presumably an open-world collection endpoint.

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

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

It is one short sentence with no wasted clauses, but the brevity comes from under-specification rather than economy of expression. The '(GET /v1/members)' fragment is the only content not already present in the title.

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

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

For a parameterless list tool with no output schema, the description should at minimum indicate what fields a member record contains or whether results are paginated. Neither is present, and the 'admin session' qualifier is never explained.

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

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

The tool takes zero parameters, so there is no parameter semantics to explain; the schema carries no burden here. Baseline 4 applies for a parameterless tool.

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

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

The description is essentially the title repeated: 'List workspace members (admin session)' restates the tool name members_list with no additional specificity. It does not distinguish itself from siblings like members_audit, members_update, or members_remove, which an agent must choose between when handling member-related tasks.

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

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

There is no explicit guidance on when to use this versus members_audit or the other member tools. The parenthetical 'admin session' faintly signals a privileged context but never states prerequisites, exclusions, or alternatives.

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