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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered by structured data. The description contributes scope detail by listing the six areas and the incident dimension. It says nothing about data freshness, aggregation window, cost/size of the response, or what happens when the token covers multiple projects.

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?

A single front-loaded sentence with no filler; the leading clause states the deliverable immediately. The parenthetical list of seven areas is dense but each item is informative rather than padding. Slightly list-heavy for what is fundamentally "returns status."

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 read-only overview with no output schema, full annotation coverage and one optional, fully-documented parameter, the description is adequate but thin. It leaves "verdict" undefined and does not describe the shape of the response or how area states and incidents relate, which matters for a broad aggregating tool.

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 coverage is 100% and the single `project` parameter is fully documented in the schema, including its multi-project disambiguation purpose. The description does not mention the parameter at all, so it adds no semantics beyond the schema. Baseline 3 applies when the schema carries this load.

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 resource ("Relia's verdict for this product") and enumerates exactly what the result contains: area states across uptime, APIs, database, servers, page speed, users and AI agents, plus incidents needing a fix. An agent can form a clear picture of the payload. It stops short of a crisp verb phrase like "Get product status" and never contrasts itself with siblings such as relia_dashboard or relia_uptime, which also surface area state.

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 when-to-use or when-not-to-use guidance, and no mention of alternatives despite an extensive sibling set (relia_dashboard, relia_uptime, relia_list_incidents, relia_vitals all overlap). The implicit framing as a top-level "what needs attention right now" suggests a starting point, but the agent must infer that itself.

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