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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered elsewhere. The description adds only framing about the pre-change audit context; it does not disclose anything further about latency, auth scope, or caching behavior that isn't already in the annotations or output schema.

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 front-loaded sentence with zero filler, though the tail is a dense comma-separated enumeration of fields. It is efficient but reads as a list rather than a tightened statement.

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 read-only, idempotent tool with full annotation coverage, a 100%-documented single parameter, and an output schema that carries the return structure, the description is nearly complete. The only shortfall is the absence of explicit sibling routing to the configure_* writes.

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?

Only one optional parameter exists, and the schema documents it at 100% coverage (defaults to first accessible business). The description adds no syntax or fallback detail beyond the schema, so the baseline 3 applies.

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?

Uses a specific verb ('Audit') plus a clearly-scoped resource ('business-level operational setup') and enumerates the exact contents (alert recipients, alert flags, escalation rules, send-link entries, agent metadata). This content list implicitly separates it from the configure_* write siblings, but it never names a contrasting tool the way a 5 would require.

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?

Provides clear usage context: this is the read to run 'before changing a live account,' establishing it as a prerequisite for the configure_* mutations. It stops short of naming those alternatives or stating when not to use it, so it falls in the 'clear context, no exclusions' band.

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