projects_members_list

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

With no annotations, the description adequately explains behavior: returns only active members and requires membership. It does not detail response fields or side effects, but for a list tool this is sufficient.

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 extremely concise: two sentences plus a tag, front-loaded with purpose and followed by behavioral details. No unnecessary words.

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?

Despite no output schema, the description covers the essential: purpose, return scope (active members), and a prerequisite. No gaps for a simple list operation.

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?

Schema description coverage is 100%, so baseline 3. The description merely restates 'Project ID' matching the schema, adding no additional meaning.

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 clearly states the tool lists members of a project, specifying 'active (non-deleted)' members. The verb 'list' and resource are distinct, and it differentiates from sibling tools like 'projects_list' and 'organizations_members_list'.

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 description mentions a prerequisite ('caller must be a member'), but lacks explicit guidance on when to use vs. alternatives or when not to use the tool. The context of sibling names provides some differentiation.

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