netintel_holidays

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

No annotations and no output schema, so the description carries the full behavioral burden, yet it says nothing about return format, permissions, or how a specific date is actually evaluated. The 'business day or weekend' claim is also ambiguous since no day-of-month parameter exists to express a target date.

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?

Three short, front-loaded sentences with no filler; the primary purpose leads and supporting facts follow. It is terse to the point of under-specification rather than verbose.

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 3-parameter tool with no annotations, no output schema, and 0% parameter coverage, the description is too thin. It omits how year/month shape results and how the business-day check is invoked, leaving real gaps an agent would hit at call time.

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 0% across three parameters. The description helpfully specifies the country format (ISO 3166-1 alpha-2), but leaves 'year' and 'month' entirely unexplained, including whether they are required to list holidays or filter results.

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+resource ('Get public holidays by country') and adds a second concrete capability (business day/weekend check). It is clear what the tool does, though it does not explicitly differentiate itself from nearby tools like netintel_calendar since no sibling covers holidays.

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?

Usage is only implied by the stated capabilities: fetching holidays and checking whether a date is a business day or weekend. There is no explicit when-to-use, when-not-to-use, or named alternative (e.g., netintel_calendar), so the agent must infer the context.

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