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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds genuine semantic context beyond that: it enumerates the agent states and defines what constitutes an alert (break over its limit, running campaign with pending contacts and no agents), which helps the agent interpret the response. It does not address data freshness guarantees or rate limits.

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?

Content is front-loaded into a single sentence that opens with the key qualifier 'right now,' and every clause carries information. The nested parentheses make it dense to parse but not padded; a slight trim would improve readability without losing meaning.

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 no output schema present, the description must carry the return-shape burden, and it does so well by enumerating campaigns, agent states, active calls, summary, and alerts. Minor gaps remain: no mention of result size, pagination, or refresh cadence for what is explicitly a live view.

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?

The single optional `fields` parameter is fully documented in the schema, including its enum of summary/campaigns/alerts, so schema coverage is 100% and the baseline is 3. The description's mention of 'a summary' and 'supervisor alerts' loosely mirrors two enum values but adds no filtering syntax or behavioral detail beyond the schema.

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 names a concrete resource and scope: a real-time snapshot of campaigns with per-state agent counts, active calls, a summary, and supervisor alerts. That is specific enough for an agent to know exactly what data comes back. It does not, however, distinguish itself from nearby siblings such as get_live_conversation_metrics or get_account_summary, so it stops short of a 5.

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 phrase 'What is happening right now across the account,' which suggests live monitoring rather than historical reporting. There is no explicit when-to-use guidance, no exclusions, and no pointer to alternatives like get_live_conversation_metrics when only conversation-level metrics are needed.

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