Read-onlyIdempotent

Get aggregated site metrics like sessions, pageviews, unique users, and bounce rate for a specified date range and filters to analyze website performance.

Instructions

Get aggregated overview metrics for a site: sessions, pageviews, unique users, pages per session, bounce rate, and average session duration. Supports date range and filters.

TDQS

B3.4/5.0

Behavior3/5

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

Annotations already declare this as a read-only, idempotent, non-destructive operation, so the safety profile is covered. The description adds only that date ranges and filters are supported, which the schema also conveys, and offers no extra behavioral context such as aggregation granularity or default time window.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two tight sentences, metric list front-loaded after the purpose, with no redundant or filler content.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present and full schema description coverage, the description does not need to explain return values or parameters. It names the metrics returned and notes range/filter support, which is sufficient for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, including detailed filter dimension and operator docs, so the schema carries the parameter burden and baseline 3 applies. The description adds no format or syntax detail beyond 'date range and filters.'

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource ('Get aggregated overview metrics for a site') and enumerates the returned metrics, so the agent knows exactly what it produces. It does not, however, distinguish itself from close siblings like rybbit_get_overview_timeseries or rybbit_get_metric, leaving the boundary to inference.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The only guidance is 'Supports date range and filters,' which describes capability rather than when to choose this tool over the many sibling analytics tools. There is no stated when-to-use, when-not-to-use, or named alternative.

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