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

Annotations already declare readOnlyHint, idempotentHint, and openWorldHint, so the safety profile is covered. The description adds useful behavioral detail by disclosing the 200 max limit and the presence of pagination.total and has_more, helping the agent understand how to page through results.

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 economical sentences with no filler. It front-loads the core action and immediately provides the only operational constraint an agent needs: the pagination limit and response fields. Every sentence earns its place.

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 read-only list tool with output schema and annotations present, the description covers the resource, scope, and pagination behavior. It does not mention ordering or alternative tools, but the schema and annotations carry enough of the remaining burden.

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 schema already documents limit and offset, including the useful 'no cursor - page with offset' note. The description repeats the max limit but adds no new parameter meaning. The required project_id remains a bare string with no explicit description, though tool context implies it identifies the project.

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 uses a specific verb ('List') and a clear resource ('team members and their allocations for a project'). It is clear and actionable, but it does not explicitly distinguish itself from sibling tools like projects_get or resources_get, so it stops short of a 5.

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 a project' implies when to use this tool, and the pagination sentence gives operational guidance. However, it does not explicitly state when to use this tool versus alternatives, nor does it name any sibling tool or exclusion criteria.

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