get_analytics_group_providers

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

Annotations already declare readOnly/idempotent/non-destructive safety. The description adds materially useful behavior annotations already don't cover: Enterprise gating, a 403 response on non-Enterprise plans, and the guarantee that requested metric fields are preserved per provider row.

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?

The core scope statement is front-loaded and efficient, but 'Enterprise-gated' is stated twice (opening and closing sentence), and the trailing 403 detail duplicates the same gating context. Mild redundancy without losing comprehension.

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?

With an output schema present, return-value description is unnecessary. The description covers scope, gating/auth failure mode, and grouping dimension, which is sufficient for correct invocation; it omits sorting/page-bound interaction detail, which is minor.

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 100%, so the schema documents all 37 params including the legacy-vs-structured alias pairs. The description only summarizes capabilities (metrics, ordering, pagination, total count) and adds no syntax or field-level meaning beyond the schema, which is the baseline-3 case.

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 provider-grouped analytics') with scope constraints (one workspace, time range) and capabilities (metrics, ordering, pagination, total count). It is clearly distinguishable from siblings like get_analytics_group_users/models, though it never names them explicitly.

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?

'Use this when comparing provider traffic or reliability' gives a concrete selection context. No when-not guidance or named alternatives are offered, so it stops short of explicit routing.

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