clokio_attendance_summary

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

Annotations already declare readOnlyHint=true and destructiveHint=false, and the description adds little behavioral detail beyond restating the resource. It does not disclose what the summary contains, whether the month is required or defaults to the current month, or how the data is aggregated.

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 has no filler, but it is so terse that it under-specifies the tool. A few more words could materially improve clarity without adding bloat.

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?

With no output schemahol and sibling tools covering daily, range, and per-employee attendance, the description should clarify what kind of summary is returned and for whom. It does not, so an agent would still have to guess at invocation behavior.

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?

The schema has 100% description coverage for the only parameter, month, with format YYYY-MM. The description merely aligns with 'monthly' and does not add any detail about optionality or default behavior, so it earns the baseline score.

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 is a noun phrase, 'Monthly attendance summary,' which indicates the resource and time granularity but lacks a verb and an explicit scope. It distinguishes from attendance_daily and attendance_range via 'monthly,' but does not clarify whether it summarizes all employees or a single employee, leaving ambiguity against attendance_for_employee.

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 given about when to choose this tool over its siblings. The word 'monthly' only implies a time period; there are no explicit when-to-use conditions, exclusions, or alternative recommendations.

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