get_provider_insights

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint true, destructiveHint false. Description adds that it returns benchmarks and issues, consistent with annotations. No additional behavioral details beyond the safe, read-only nature.

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 sentences: first defines the action, second states usage context. Front-loaded with key purpose. No redundant or vague phrases.

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?

No output schema, but description indicates return of 'security benchmarks and common configuration issues'. Sufficient for a fast, read-only lookup tool. Covers the 3 parameters implicitly.

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%. Description adds context for 'provider' (e.g., 'Google Workspace customers') and hints at what 'profile' and 'format' control. Adds meaning beyond the schema's enum descriptions.

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 tool returns security benchmarks and configuration issues for a specific provider cohort (e.g., Google Workspace). It distinguishes from sibling tools like check_dmarc (per-domain) by focusing on provider-level aggregation.

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?

Explicitly says when to use: 'when asked how an email service provider compares to competitors...' or 'to see typical misconfigurations for a named vendor's customers'. Implicitly excludes individual domain checks, but no explicit alternative naming.

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