rc_get_overview

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

With no annotations, the description carries the full burden. 'Get a snapshot' reasonably implies a read-only, non-mutating operation, and the metric list clarifies what kind of data is returned. However, it does not disclose response structure, time range, or any other behavioral nuances.

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 description is a single sentence that leads with the action and then lists the exact metrics included. Every word is useful, with no redundancy.

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 zero-parameter, no-annotion, no-output-schema tool, the description gives enough detail about what the overview includes. It could be richer about whether metrics are current values or time-bounded, but the term 'snapshot' partially covers that.

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?

There are zero parameters, so the schema already fully covers the parameter surface. The description needs to add no parameter-level meaning, earning the baseline for a zero-parameter tool.

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 clearly states the tool gets a snapshot of key subscription metrics and explicitly enumerates them (MRR, active subscriptions, trials, revenue, new customers, active users). This gives a specific verb and resource, though it does not explicitly contrast with sibling tools.

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?

The 'snapshot' wording implies this is for a high-level overview of current subscription health, but no explicit when-to-use or when-not-to-use guidance is provided. It does not mention alternatives like rc_get_chart or rc_compare_periods.

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