manage_roles

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

No annotations are provided, so the description carries full behavioral disclosure burden. It fails to disclose that this appears to be a dispatch/router tool selecting between 'list' and 'guidance' behaviors, nor does it explain any side effects, auth requirements, or how the nested 'context' object behaves. The description adds essentially nothing beyond what the name conveys.

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 a single short phrase, which is concise, but this is under-specification rather than effective conciseness. There is no opening framing for a multi-action dispatcher tool that handles two distinct behaviors (list and guidance). The word count is low, but it fails to earn its place by adding no useful information.

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 handles two distinct actions ('list' and 'guidance'), has a nested object parameter with no structure defined, and no output schema, the description is insufficient. The agent cannot know what the 'context' object should contain, what role guidance returns, or how this differs from get_guidance. A multi-action dispatcher with no annotations needs far more documentation.

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 100%, so the schema already documents each parameter. However, the description adds no semantic value beyond the schema. The relationship between parameters (e.g., that 'context' and 'roleId' are relevant only for 'guidance') must be inferred from the schema names. Baseline 3 applies since the schema handles parameter documentation.

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 'Unified role management operations' is extremely vague-it names a generic category rather than specifying verb+resource. It doesn't clarify what 'management' means (create? assign? delete?). With siblings like 'list_roles' and 'transition_role', the purpose is ambiguous and doesn't differentiate what manage_roles does uniquely.

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 tool versus the alternatives. The 'unified' wording hints it's an aggregator or dispatcher, but nothing tells the agent when to choose manage_roles over list_roles, transition_role, or get_guidance. The schema's action enum ('list', 'guidance') implies it overlaps with list_roles and get_guidance, but this is unstated.

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