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

No annotations are provided, so the description carries the behavioral burden. It does disclose the response behavior—pong, server time, and connection status—but it does not state whether any state changes occur, whether a live network check is performed, or how connection status is determined. Adequate but thin.

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?

One sentence with a colon-separated list of return values; no filler and the main action is front-loaded. Every part earns its place.

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?

For a low-complexity tool with one optional parameter and no output schema, the description provides the essential return components. The remaining gaps—no routing hint against `connection_status` and no note on how `echo` affects the response—are minor.

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%: the single optional `echo` parameter is fully documented in the schema. The description adds no parameter-specific behavior, but the baseline of 3 applies because the schema already does the heavy lifting.

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 names the action ('Ping MCP server') and lists observable outcomes (pong, server time, WA connection status), so an agent knows what the tool does. It does not explicitly differentiate it from the sibling tool `connection_status`, which also reports WA connection status, so it misses the full sibling-distinction mark.

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?

There is no guidance about when to use `ping` instead of `connection_status`, `doctor`, or `auth_qr`. Since `connection_status` overlaps with the 'status koneksi WA' behavior, the lack of a routing clue is a notable gap.

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