get_attendance_history

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

With no annotations, the description carries the full behavioral burden, yet it only discloses recency ('Recent') and a return exclusion ('no QR contents'). It does not clarify read-only behavior, time-window definition, permissions, pagination, or what 'pairs' structurally means.

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?

It is a single, short sentence with no filler, and the key scope ('Recent') is front-loaded. The phrasing 'the pairs where attendance was marked' is slightly awkward but not verbose.

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 schema and no annotations, the description should explain the shape and scope of returned data, but 'pairs' and 'events' go undefined and no time window is specified. An agent would have to call it blind to understand its output.

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?

There are zero parameters and no parameter schema to compensate for, so the baseline of 4 applies. The description correctly does not invent parameter details.

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 identifies the resource as recent QR events and attendance-marked pairs, which hints at an attendance-history read. However, it is a noun phrase with no clear verb, and terms like 'pairs' are ambiguous — an agent cannot confidently tell what records are returned or how this differs from a generic history tool.

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 indication of when to call this versus any alternative, and no prerequisites or context are given. The sibling list contains no obviously related tool, but the description still offers no usage guidance.

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