Month-End Close Checklist

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

Annotations already indicate readOnlyHint=true, idempotentHint=true, and destructiveHint=false, which are consistent with the description. The description adds behavioral context by explaining the 'fresh' parameter's effect on caching, which goes beyond 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 sentence followed by parameter descriptions. It is concise, front-loaded, and contains no superfluous 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?

The description lists checklist categories but lacks explanation of output format or structure. No prerequisites or post-conditions are mentioned. Given no output schema, more detail on the return value would be helpful. The 'fresh' parameter adds some context.

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 coverage is 100% with parameter descriptions. The tool description adds context about the checklist contents but does not enhance parameter semantics beyond what the schema provides. Baseline 3 is appropriate.

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 it generates a month-end checklist with specific categories (unconfirmed journals/invoices, unreconciled bank transactions, overdue receivables/payables). This distinguishes it from sibling tools like 'prepare_year_end_close' or 'compute_balance_sheet'.

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 description implies usage for month-end close checks but does not explicitly state when to use this tool versus alternatives, nor does it mention when not to use it. There is no guidance on prerequisites or exclusions.

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