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

No annotations are provided, and the description only says 'Get' which implies read-only but does not confirm safety, side effects, authentication needs, or response format. The description carries the full burden for behavioral disclosure but fails to add any meaningful detail.

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 sentence, but it lacks essential information. Conciseness should not come at the cost of completeness; the description is under-specified and does not earn its place.

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 large number of sibling tools and lack of output schema or annotations, the description is severely incomplete. It does not explain the returned metrics, how to interpret results, or any conditions for use.

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?

The schema describes the parameter 'enterprise' with a trivial description 'enterprise'. The description does not add any context about what this parameter represents or how to use it, providing no additional value beyond the schema.

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 'Get Copilot users usage metrics' clearly indicates a read operation for Copilot user metrics, but it does not specify whether this is for an enterprise, organization, or individual users. Given the sibling tools like 'github_copilot_copilot_organization_users_usage_metrics' and 'github_copilot_copilot_enterprise_usage_metrics', the description fails to differentiate the scope.

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 its many siblings. The description does not mention any alternatives or constraints, leaving the agent without context for selection.

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