splunk_get_role_capabilities

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

No annotations are supplied, so the description carries the safety burden; it implies a read-only inspection by saying it 'gets' capabilities and restrictions, but never states that explicitly. It also omits what happens for a nonexistent role (empty result vs. error) or any permission requirements. The return payload is covered by the output schema, which offsets part of the 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?

One front-loaded sentence stating the action, followed by a short Args block; nothing is padded. The Args line largely duplicates the schema title, so it is efficient rather than exemplary.

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 single-parameter read tool with an output schema, the essentials are present: what it returns and an example role name. Missing are error/failure semantics for invalid role names and any pointer to the related list/manage role tools, which matter in a 90+ tool surface.

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% — the schema only gives the title 'Role Name'. The description partially compensates by listing example values ('admin', 'user', 'power'), which clarifies expected format. It still leaves open exact-match vs. case sensitivity and whether built-in roles are the only valid input.

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?

States a specific verb ('Get') and resource ('granular capabilities and restrictions assigned to a specific role'), so the agent knows exactly what data comes back. It does not, however, differentiate itself from nearby siblings like splunk_list_roles or splunk_manage_role, which an agent could confuse with this lookup.

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 statement of when to use this versus splunk_list_roles (enumerate roles) or splunk_manage_role (mutate roles), and no prerequisites such as needing a role to already exist. Only the shape of the argument hints at usage.

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