sophos_create_tenant_role

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

No annotations exist, so the description bears full burden. It only states 'Create a custom role,' implying mutation but does not disclose side effects, permissions required, idempotency, constraints (e.g., name uniqueness), or error conditions. Inadequate for a creation operation.

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?

Two sentences: one for purpose, one for usage hint. Extremely concise, front-loaded, and without redundancy. Every sentence adds 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?

Tool has 4 parameters, no nested objects, no output schema, and no annotations. The description fails to mention return value, error handling, prerequisites (e.g., authentication context), or constraints. Incomplete for an agent to use correctly without guessing.

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 100% with brief but present parameter descriptions. The tool description adds context for permission_set_ids (referencing sophos_list_tenant_permission_sets). This is marginal improvement beyond the schema, so baseline 3 is appropriate.

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 'Create a custom role in a tenant,' specifying the action and resource. It distinguishes from sibling tools like sophos_create_partner_role by scoping to tenant, and references the sibling tool sophos_list_tenant_permission_sets for prerequisite discovery.

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?

Provides a specific prerequisite hint (discover permission sets via sophos_list_tenant_permission_sets), but lacks explicit guidance on when not to use this tool (e.g., for updates use sophos_update_tenant_role, for partner-level roles use sophos_create_partner_role). No exclusion criteria or alternative use cases mentioned.

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