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

No annotations are provided, so the description carries the full burden of disclosing side effects and operational behavior. It does not explicitly state that this is a read-only query, nor does it describe any permissions, data scope, or impact. The description adds some behavioral context (the comparison of billable vs free minutes), but not enough to satisfy transparency without annotations.

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, dense sentence with no wasted words. The parenthetical 'free-tier headroom' adds a useful interpretive frame without bloating the text.

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 simple tool with two optional parameters and no output schema, the description gives the core concept but omits details like return format, how to interpret the comparison, or relationship to sibling cost tools. It is adequate but leaves room for clarification.

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 baseline is 3. Both 'org' and 'month' are described in the schema with defaults and format. The description's mention of 'for a month' aligns with the month parameter but does not add any semantic detail beyond what the schema already conveys.

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 identifies the resource: billable vs included-free minutes for a month, and adds the useful context of 'free-tier headroom.' It lacks an explicit verb (e.g., 'get' or 'show'), but the meaning is unambiguous and distinguishes it from sibling cost-focused 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 phrase 'free-tier headroom' implies this is for monitoring usage against free allowances, providing some usage context. However, there is no explicit when-to-use guidance, no mention of alternatives, and no exclusions distinguishing it from the many sibling cost/usage tools.

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