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 discloses that the tool retrieves health status and identifies potential data gaps, which is useful behavioral context. However, it does not mention performance characteristics (e.g., latency), error handling, or whether it requires active connections, leaving gaps in transparency for a tool with no annotation support.

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, well-structured sentence that efficiently conveys the tool's purpose and key details (uptime, disconnects/reconnects, gaps). It is front-loaded with the main action and avoids unnecessary elaboration, making every word count.

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 no annotations and no output schema, the description provides a clear purpose but lacks details on return format, error conditions, or dependencies. For a health-check tool with zero parameters, it is minimally adequate but could benefit from mentioning output structure or usage constraints to improve completeness.

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 tool has 0 parameters with 100% schema description coverage (empty schema). The description does not need to add parameter details, as there are none to document. It appropriately focuses on the tool's purpose without redundant parameter explanations, meeting the baseline for zero-parameter tools.

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 verb ('Get') and resource ('detailed connection health status'), specifying what information is retrieved (uptime, recent disconnects/reconnects, connection gaps). It distinguishes from sibling tools like 'ensure_connection' (which likely establishes connections) and 'get_network_stats' (which focuses on network metrics rather than connection health).

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 implies usage for monitoring connection health and identifying data gaps, but does not explicitly state when to use this tool versus alternatives like 'get_network_stats' or 'ensure_connection'. It provides context about what the tool does, but lacks explicit guidance on prerequisites or exclusions.

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