health.inspect_day

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

With no annotations, the description partially reveals behavior: it combines data and explains gaps. However, it omits details like whether the tool is read-only, required permissions, or side effects. A score of 3 is appropriate as it adds some transparency but is not fully comprehensive.

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?

Two sentences, front-loaded with purpose and outcome. Every word is necessary; no 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 complexity (4 parameters, output schema exists, multiple siblings), the description is mostly complete. It covers the core function. Minor gap: does not clarify output format, but output schema exists. Lacks usage guidelines, but that dimension is separate.

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?

Input schema has 100% description coverage, so baseline is 3. The description does not add additional meaning to parameters beyond what the schema provides. It mentions 'combining snapshot and raw manifest' but does not link to specific parameters.

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 clearly states the tool inspects a single day by combining daily snapshot with raw manifest and explains metric/raw gaps. The verb 'inspect' is specific, the resource is 'one day', and it differentiates from sibling tools like `health.analyze_range` which operates on ranges.

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 explicit guidance on when to use this tool versus alternatives. It does not mention when not to use it or provide context for selection among siblings like `health.analyze_range` or `health.read_daily_metrics`.

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