grid402_summary

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

No annotations exist, so the description carries the full burden, and it does disclose a behavior an agent cannot get from structured fields: the call is free and incurs no x402 charge, which matters for a paid-service family. It also states coverage breadth (all 6 services). It does not say what the response looks like or how degraded services are reported, but for a zero-argument read-only status call the burden is low.

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 sentence that front-loads the verb and resource and appends the cost caveat as a parenthetical rather than burying it. Nothing is redundant or padded.

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 simple zero-parameter aggregate tool with no output schema, the description tells the agent what is summarized and that it costs nothing, which is enough to call it correctly. The only gap is the shape of the result (per-service status vs. a single boolean), which is left implicit.

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 takes no parameters, so the baseline is 4 and there is nothing for the description to clarify or compensate for. No parameter claims are made that could conflict with the empty schema.

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?

States a specific verb ('Consulta') and a specific resource ('resumo consolidado de saúde e disponibilidade') scoped to the 6 Grid402 micro-services. It is clearly an aggregate status endpoint, which distinguishes it in spirit from the single-purpose siblings (cnpj, forex, dns, ssl...), though that contrast is never made explicit.

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?

No when-to-use or when-not-to-use guidance is given; the agent must infer that this is the overview check to run before or instead of the individual service tools. The implicit usage (health check / pre-flight before calling grid402_cnpj, grid402_forex, etc.) is reasonably evident from the name and description.

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