get_login_stats

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

No annotations are provided, so the description must cover behavioral traits. It implies read-only stats retrieval, but does not clarify pagination behavior, result limits, or whether it is a simple query. This is adequate but not detailed.

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?

Description is extremely concise: one line for purpose and a structured Args section. Every sentence provides value without redundancy.

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 has only 2 optional parameters and an output schema, the description completes the picture for basic usage. It explains parameter defaults and pagination, though could mention what aggregate stats include.

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%, but the description adds significant meaning: explains date_from defaults to last 24h (with KEYCLOAK_DEFAULT_DATE_FROM_HOURS) and date_to empty for all time. This goes beyond the bare 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?

Description clearly states 'Get login success/failure statistics with full pagination', which distinguishes it from siblings like get_login_failures_by_ip and get_login_stats_by_client, as it focuses on overall stats with pagination.

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?

Description mentions pagination but provides no explicit guidance on when to use this tool versus alternatives. The context of sibling tools implies differentiation, but the description itself lacks direct usage advice.

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