dcs_role

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

The "[READ]" tag merely restates the readOnlyHint=true annotation already supplied, adding no new behavioral context. Nothing is said about what happens with a nonexistent or unauthorized role_id, nor about error or not-found behavior.

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?

A single short sentence with the tag front-loaded; nothing is wasted. However, the brevity borders on under-specification rather than efficient structure.

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 one-parameter read tool with readOnlyHint covering the safety profile, the essentials are nearly present. The missing piece is the origin/semantics of role_id and error behavior, which an agent needs to call it correctly the first time.

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 0%: role_id is typed integer but has no description, and the tool description does not compensate by explaining where role_id comes from or whether it is the internal or external identifier. With one required parameter fully undocumented, the meaning gap is real.

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?

"Read one RBAC role" gives a specific verb (read) and resource (RBAC role), and the word "one" implicitly separates it from the list sibling dcs_roles. It stops short of explicitly naming that sibling, so differentiation relies on inference.

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 when-to-use or when-not-to-use guidance and no mention of dcs_roles as the listing alternative. The agent must infer that this is the single-record fetch from the word "one".

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