github_api_insights_get_summary_stats

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

No annotations are present, and the description fails to disclose behavioral traits like whether this is a read-only operation, authentication requirements, or data scope (e.g., organization-level stats). The short description does not compensate for the lack of annotations.

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 only one sentence, which is concise, but it lacks substance to be effective. It is minimally structured but not overly verbose; however, the brevity comes at the cost of clarity.

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?

The description is incomplete for a tool with three parameters and no output schema. It does not explain what the returned summary stats contain, how they relate to other API insights tools, or any important constraints like rate limits. Sibling context suggests differentiation is needed but absent.

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 input schema provides full descriptions for all three parameters (org, min_timestamp, max_timestamp) with ISO 8601 format details. The description adds no additional context, but since schema coverage is 100%, the baseline of 3 is appropriate.

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 summary stats' is vague, lacking specificity on what summary stats refer to (e.g., GitHub API Insights for an organization). It does not differentiate from sibling tools like get_summary_stats_by_actor or get_subject_stats, requiring the agent to infer scope from the tool name alone.

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 omits context such as prerequisites, typical use cases, or exclusion criteria, leaving the agent to rely on the tool name and schema.

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