health

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

No annotations are provided, so the description must carry the burden of behavioral disclosure. It only states that health is checked, but does not mention whether the operation is read-only (likely, but not stated), what the output format looks like, or any side effects. For a tool that presumably performs a read-only check, lacking explicit read-only disclosure is a significant gap, especially with no annotations to fall back on.

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 that conveys the core purpose without waste. It is appropriately front-loaded and easy to parse. It earns a high score because it is concise and to the point, though a bit more specificity could be added without breaking conciseness.

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's simplicity (no output schema, no required parameters, no nested objects), the description is minimally sufficient for basic understanding. However, since annotations are absent and there's no output schema, the description fails to disclose return behavior or any system-specific health semantics. For a health-check tool, agents may need to know what a healthy state looks like or how to interpret results, which is missing.

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%, and both parameters are well-described in the schema. The description adds no extra semantic information about parameters, but given the high schema coverage, the baseline of 3 is appropriate. The 'verbose' parameter's effect is documented, and '_agent_id' has a clear purpose, so the description doesn't need to repeat those details.

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 'Check system health status.' clearly states the verb (check) and resource (system health), making its purpose understandable. However, given the large set of sibling tools covering memory operations, there's no explicit differentiation from potential health-like tools, but no sibling appears to directly compete. The simplicity is adequate but could be more specific about what 'health' means (e.g., service status, database connectivity).

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?

The description provides no guidance on when to use this tool versus alternatives, nor any context about typical use cases or exclusions. Since the siblings are diverse (memory operations, stats, namespaces), a brief note on when to check health (e.g., before other operations) would help. The absence of any timing or conditional advice leaves usage entirely implicit.

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