Generate a CSV report of expenses for a given month, saved to the reports directory.

Instructions

A3.7/5.0

Behavior3/5

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

With no annotations, the description carries full burden. It discloses the side effect of saving to /reports/ and the return as a CSV string. However, it lacks details on error handling, permission requirements, or whether the file overwrites or appends.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, no redundancy, front-loaded with the primary action. Every word adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given an output schema exists (not shown), the description correctly focuses on behavior rather than return format. It mentions the side effect of saving to a file, which is important. However, it could clarify parameter constraints and the relationship to generate_excel.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0%, and the description only says 'for a given month' without explaining format or constraints (e.g., month 1-12, year range). It adds little beyond the parameter names, failing to compensate for low schema description coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'Export all expenses for a given month as a CSV string', specifying the verb (export), resource (all expenses for a month), and output format (CSV string). It also mentions a side effect (saving to /reports/). This distinguishes it from the sibling tool generate_excel, which exports to Excel format.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage when a CSV of monthly expenses is needed, but does not explicitly state when not to use it or compare to the alternative generate_excel. No guidance on prerequisites or limitations is provided.

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