dcs_roles

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

Annotations already declare readOnlyHint=true, and the '[READ]' prefix merely restates that without adding context. The description says nothing about result ordering, pagination behavior with the default limit of 100, or whether the list is scoped to the caller's tenant.

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?

One short, front-loaded sentence with no filler. The only waste is the redundant '[READ]' marker given the readOnlyHint annotation.

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 list endpoint with no output schema, the description should indicate what a role record contains and how the limit affects results. It provides neither, leaving the agent with less information than it needs to call the tool confidently.

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% for the single 'limit' parameter, so the description should clarify what it bounds and whether there is a maximum or pagination cursor. It adds no parameter meaning at all, leaving the default of 100 and any cap undocumented.

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 and resource ('List RBAC roles'), which is unambiguous about what the tool returns. It does not distinguish itself from the singular sibling 'dcs_role' or 'dcs_role_users', so an agent must infer that this is the collection-level listing.

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?

No guidance on when to use this versus 'dcs_role' (single role) or 'dcs_role_users'. The '[READ]' tag hints at read-only intent but that is already conveyed by annotations, not a usage rule.

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