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

With no annotations provided, the description carries full burden for behavioral disclosure. It only lists output fields and does not mention whether this is a read-only operation, auth requirements, rate limits, or how the month range is determined beyond the default. This is minimal transparency.

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 concise sentence that front-loads the key information: what the tool returns (headline cost) and its composition (total jobs, billable minutes, dollar cost). No wasted words.

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 summary tool with 100% schema coverage and no output schema, the description is adequate. However, given the large number of sibling cost tools, a brief note on how this relates to or differs from cost_overview or monthly_usage would improve completeness.

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. The description mentions 'month' but does not add any additional semantic nuance beyond what the schema already provides for org and month parameters.

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 provides a monthly headline cost with total jobs, billable minutes, and dollar cost. It is specific about the resource (monthly summary) and outputs, though it does not explicitly differentiate from sibling cost 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?

No guidance is provided on when to use this tool versus the many cost-related siblings (e.g., cost_overview, monthly_usage, cost_daily). The phrase 'for a month' implies a monthly summary, but there are no exclusions or alternative tool suggestions.

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