m365_manage_group_member

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

No annotations are provided, so the description carries the full burden. It implies a mutation but says nothing about required permissions (owner rights), whether removal is reversible, whether external/non-member addresses are allowed, or what happens on failure. Only the add/remove duality is disclosed.

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?

A single front-loaded sentence with the operation and allowed action values, no filler. It is efficient, though it could carry one more clause of behavioral context at the same cost.

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?

The presence of an output schema means return values need not be explained. For a simple two-mode mutation the core intent is covered, but the absence of any permission, error, or eligibility context leaves an agent under-informed about safe invocation.

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 coverage is 0% and the schema declares no enum, so the description's mention of action values 'add'/'remove' adds genuine meaning the schema lacks. However, group_identity (name vs. address vs. ID) and member_email formats are left entirely undefined, so the description only partially compensates for the coverage gap.

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?

States a specific verb (adds/removes) and resource (user from a distribution group), which clearly separates it from read-oriented siblings like m365_get_group_members and m365_list_distribution_groups. It does not explicitly name those siblings, but the action framing is unambiguous.

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 lists the two action values but gives no when-to-use guidance, prerequisites, or alternatives. There is no indication of when a user should choose this over m365_set_group_external_delivery or other group-management siblings.

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