check_alert_status

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

Even though annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false, the description adds valuable behavioral context: it reads configuration from .env and requires no caller-supplied email. This external dependency and the absence of parameters go beyond what annotations alone convey.

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 tightly written sentences deliver all essential information: what is checked, the source of the email, and the absence of required input. There is no filler, and the most actionable detail (no email input needed) is front-loaded.

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 zero-parameter, read-only status tool with no output schema, the description is complete. It enumerates the status components returned and removes ambiguity about input and configuration source, so an agent can call it correctly without further investigation.

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?

With zero parameters, the baseline is already 4, and the description exceeds it by explicitly addressing why no email parameter exists and where the recipient email comes from (RECIPIENT_EMAIL in .env). This prevents an agent from inventing or expecting an email parameter.

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 a specific verb ('Check'), a clear resource ('the monitoring system status'), and the concrete facts it returns: spike alert and daily summary scheduling, today's alerts, and the configured recipient email. This is more specific than any sibling tool and establishes a distinct identity.

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 clearly states that no email input is needed because RECIPIENT_EMAIL is read from .env, which is useful usage context. However, it does not explicitly say when to prefer this tool over related tools like send_test_spike_alert, send_daily_summary_now, or check_vnstat_status; usage guidance is only implied.

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