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

No annotations are provided, so the description carries the full behavioral burden. It discloses role-based scoping of filters, which is useful authorization context, but omits whether the export is read-only/generating a file, how it is returned, or any rate/size limits.

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?

Two tight sentences that front-load the action and output formats, then the scoping caveat. No wasted words, though it could be slightly more explicit about the format parameter's role.

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 7-parameter export tool with no output schema and no annotations, the description is minimal. It covers formats and scoping but leaves return behavior, file delivery, and read/mutation nature unaddressed.

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% and every parameter is documented in the schema, including enums and formats. The description adds only the role-scoping caveat for filters, giving baseline 3 since the schema does the heavy lifting.

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?

States a specific verb (Exports) and resource (timesheet report) plus the output formats, which is more than the name alone conveys. However, it does not differentiate from the sibling ListTimeSheetReportOptionsTool, which an agent might confuse with this one.

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 (export a timesheet report) but gives no explicit when-to-use guidance or when to prefer this over ListTimeSheetReportOptionsTool. The role-scoping note is a conditional hint but not a usage rule.

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