set_member_permissions

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

With no annotations, the description carries the full burden. It does disclose one real behavioral trait beyond the schema: 'Replace (full update)' signals that this overwrites the permission set rather than patching it. However, it omits auth/role requirements, reversibility, and the practical consequence that omitted boolean fields (default false) are reset.

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 two opening sentences and the endpoint are well front-loaded and earn their place, but they are followed by a long, heavily redundant keyword blob ('set member permissions, update permission, replace permission, edit permission...') that inflates the definition without adding selection value.

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?

This is a mutation tool with no annotations, no output schema, and 0% parameter description coverage on a five-field nested object. The description should compensate with auth requirements, replace semantics detail, and field guidance, but it leaves significant gaps for an agent to call it correctly.

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 0%, and the description adds essentially nothing about the single nested body parameter (userId, canInvite, canManage, canOrganize, canManageHousehold). 'Replace (full update)' weakly implies all fields should be supplied, but no field meaning, format, or default behavior is explained beyond the schema.

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 states a specific verb+resource ('Set Member Permissions') and adds a meaningful qualifier ('Replace (full update) permission') plus the endpoint '[PUT /api/households/permissions]'. It is clear what the tool does, but it does not differentiate itself from any sibling (e.g. there is no explicit comparison to a partial-update or get-permissions tool).

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?

There is no statement of when to use this tool versus alternatives, no prerequisites, and no exclusions. The only usage context is the generic 'Households: Self Service' tag and the endpoint path, which imply scope but do not guide selection.

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