update-member-permissions

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

No annotations provided, so description must carry burden. It mentions only one constraint (single group per product) but fails to disclose if the operation is destructive, idempotent, or requires specific permissions. The behavior of setting multiple groups or effect on existing permissions is unclear.

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?

Three sentences covering primary action, secondary use, and a key constraint. No redundancy, but could be slightly more efficient by combining first two sentences.

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?

Covers the main action and a crucial constraint, but lacks details on response format, error scenarios, preconditions (member existence), and the effect of removeFromPermissionGroupsWhereIdNotSet (though the parameter name is clear). Adequate for basic use but not comprehensive.

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 descriptions cover all parameters well (100% coverage). Description adds value by linking permissionGroupIds to moving between groups and stating single-group constraint, but does not explain interaction between isAdmin, isBillingManager, and groups.

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 clearly states updates member permissions and can move between permission groups, distinguishing it from sibling tools like create-permission-group or delete-organization-member. The constraint 'only a single Permission Group per Product' further clarifies scope.

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?

Description implies when to use (update permissions, move groups) but lacks explicit guidance on when not to use or alternative tools. No mention of prerequisites or side effects.

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