get_attendance_summary

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

No annotations are provided, so the description carries the full disclosure burden. "Get" implies a read, but nothing is said about auth requirements, what the summary contains (counts, hours, status), or whether it reflects a fixed window — the only behavioral hint is the self-scoping phrase "signed-in employee."

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?

A single front-loaded sentence with no filler — appropriately sized for a zero-param read tool. It is terse rather than padded, though the terseness edges into under-specification.

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 annotations and no output schema, the description is the only source of information, yet it never says what the "summary" actually returns. For a tool whose output an agent must interpret, that omission leaves a real gap.

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 tool takes zero parameters, so there is nothing for the description to clarify beyond what the empty schema already shows. Baseline 4 applies.

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 names the resource (attendance) and the scope (current, signed-in employee), so the agent knows it returns today's attendance picture for the caller. However, "summary" is vague about content, and it makes no attempt to distinguish itself from close siblings like get_attendance_status, get_attendance_calendar, or get_last_week_attendance.

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?

There is no when-to-use guidance, no exclusions, and no routing to alternatives. With five attendance-related siblings in the toolset, the agent is left to guess whether this or get_attendance_status is the right call.

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