update_workspace_roles

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

With no annotations provided, the description carries full burden for behavioral disclosure. It reveals the batch operation limit (50 operations per call), which is useful, but fails to mention that this is a mutation tool requiring specific permissions, whether changes are reversible, or what happens to existing roles not mentioned. For a permission-modifying tool, this is a significant gap.

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 description is a single, efficient sentence that communicates the core purpose and a key constraint. Every word earns its place with zero redundancy or unnecessary elaboration.

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 complex role-update tool with 3 parameters, no annotations, and no output schema, the description is insufficient. It doesn't explain the batch operation structure, permission requirements, error handling, or response format. The 50-operation limit is helpful but doesn't compensate for other critical gaps in behavioral context.

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 67%, and the description adds minimal value beyond the schema. It mentions 'users and groups' which aligns with the path enum values, and 'limited to 50 operations' references the maxItems constraint, but doesn't explain the operations structure, identifierType purpose, or role assignment semantics 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 clearly states the verb 'update' and resource 'workspace roles for users and groups', making the purpose immediately understandable. It doesn't explicitly distinguish from sibling tools like 'update_collection_roles' or 'get_workspace_roles', but the specificity of 'workspace roles' provides adequate differentiation.

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 provides no guidance on when to use this tool versus alternatives like 'update_collection_roles' or 'list_workspace_roles'. It mentions a technical constraint (50 operations limit) but offers no contextual usage advice, prerequisites, or comparison with sibling tools.

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