health_report

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

No annotations are provided, so the description carries the full burden. It only says 'Generate structured health reports' without disclosing whether the operation is read-only, what permissions are needed, what side effects exist, or what the output format is. This is insufficient for a tool with no output schema.

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 sentence with no filler or redundant information. It is front-loaded with the action and object, making it easy to scan.

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 there is no output schema and no annotations, the description is too minimal to provide complete context. It does not specify what a health report contains, how it is structured, or any edge-case behavior. The presence of sibling tools and moderate parameter count (4) calls for more explanatory content.

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 baseline is 3. The description adds minimal value beyond the schema—it merely echoes the 'specific period' concept already covered by start_date and end_date descriptions. It does not explain report_type enum semantics or include_metrics default behavior.

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 states a specific action ('Generate') and resource ('structured health reports') with a scope ('for a specific period'). It is clear what the tool does, though it does not explicitly distinguish itself from sibling tools like health_query or health_schema beyond the word 'report'.

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?

Usage context is implied by the description: it generates reports for a period. However, there is no explicit guidance on when to use this tool versus siblings, nor any alternative or exclusion criteria.

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