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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description adds only the filtering dimensions and no extra behavioral context such as ordering or default result scope, so it meets but does not exceed the lower bar set by the annotations.

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?

Two short sentences with zero filler, and the purpose statement is front-loaded ahead of the filter summary. Nothing is redundant with the title or restated unnecessarily.

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 zero-required-parameter read-only list tool with full schema documentation and no output schema, the description supplies enough to select and call it; pagination semantics are covered inside the schema property descriptions. Only minor gaps remain (no statement of default sort/scope when unfiltered).

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 the baseline is 3. The description's filter list glosses project_id, user_id and is_active but omits search, page and per_page, adding little meaning beyond what the schema already documents.

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 names a specific verb and resource ('List project team members') and scopes it with the available filter dimensions. It is clearly distinguishable from the sibling get_project_team_member (single record) and create/update/delete variants, though it doesn't explicitly say so.

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?

'Filter by project, user, or active status' implies when this tool is useful (retrieving memberships under a scope), but no alternative is named and no when-not condition is given. A reader must infer that this is the enumeration counterpart to the single-record getter.

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