C2.6/5.0

Behavior2/5

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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the description's only added value is the word 'Replace', which hints that the prior role is overwritten. It does not disclose whether the change is reversible, whether owner-only authorization is needed, or what happens to permissions granted by the old role — meaningful gaps for a destructive mutation.

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

Conciseness3/5

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

A single short, front-loaded sentence with no filler, which is good. However, at this length it reads as under-specification rather than economy, given the destructive mutation and undocumented parameters.

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

Completeness2/5

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

For a destructive three-parameter mutation with no parameter descriptions and an output schema, the description should cover preconditions, authorization, and effects on existing permissions. It covers none of these, leaving the agent under-informed about consequences.

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

Parameters2/5

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

Schema description coverage is 0%, so the description carries the full burden for three parameters and adds nothing beyond the names. The 'role' enum values (owner/editor/viewer) and the meaning of teamId/userId semantics (e.g., numeric user ID vs. username) are undocumented anywhere.

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

Purpose4/5

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

States a specific verb ('Replace') and resource ('a team member's role'), so the operation is unambiguous. It does not explicitly distinguish itself from nearby siblings such as remove_team_member or add_shop_list_* style membership tools, but the name plus description make the intent readable.

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

Usage Guidelines2/5

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

There is no guidance on when to use this versus remove_team_member, leave_team, or send_team_invite, nor any stated preconditions such as requiring ownership or the member already existing. The agent must infer all usage context.

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