role_list

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states it's a list operation, implying read-only behavior, but doesn't clarify aspects like whether it requires specific permissions, how it handles errors, or if it returns paginated results. For a tool with zero annotation coverage, this is a significant gap in transparency.

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 appropriately sized and front-loaded, with the core purpose stated first followed by parameter and return explanations. Every sentence adds value, though the structure could be slightly improved by integrating parameter details more seamlessly rather than as a separate 'Args' section.

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?

Given the tool's low complexity (2 parameters, no output schema, no annotations), the description is minimally adequate. It covers the purpose and parameters but lacks details on usage guidelines, behavioral traits, and output specifics (e.g., what 'basic information' includes). For a read operation with no annotations, more context would be beneficial.

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%, so the description must compensate. It adds meaning by explaining that 'context_name' is the Kubernetes context name and 'namespace' is the Kubernetes namespace, which clarifies the parameters beyond their titles. However, it doesn't provide details like format examples or constraints, leaving some ambiguity.

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 ('List') and resource ('all Roles in a given namespace'), making the purpose specific and understandable. However, it doesn't explicitly differentiate from sibling tools like 'role_get' or 'clusterrole_list', which would require mentioning it returns basic information for multiple roles rather than detailed single-role data or cluster-wide roles.

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 is provided on when to use this tool versus alternatives. The description doesn't mention sibling tools like 'role_get' (for single role details) or 'clusterrole_list' (for cluster-wide roles), nor does it specify prerequisites such as needing proper Kubernetes access. This leaves the agent without context for tool selection.

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