list_project_members

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

The description discloses that the project is automatically determined from the API key, which is a useful behavioral detail. However, it does not explicitly state that the operation is read-only or mention any other side effects, rate limits, or authentication requirements, leaving much to inference.

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?

The description is two short sentences with no redundant information. It directly states the action and a key operational detail, making it easy to parse and act upon.

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 simple list tool with no parameters and no output schema, the description provides sufficient context: it states what it lists, the purpose, and the auto-determination of the project. It does not specify the response format, but the name and purpose make it reasonably clear that a list of members is returned.

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 has zero parameters, so no semantic explanation is needed. The description adds value by clarifying that the project is inferred from the API key, effectively explaining why no project parameter is required. This exceeds the baseline for no-parameter tools.

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?

Clearly specifies the verb 'list' and the resource 'members of the project', with a parenthetical purpose 'for task assignment' that distinguishes it from sibling tools focused on tasks, sessions, and attachments. The description is unambiguous about what this tool does.

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?

The phrase 'for task assignment' implies when to use it (to obtain assignable members), but it does not explicitly state when not to use it or how it compares to alternatives like list_tasks or get_task. Guidance is present but only implicit.

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