get_attendance_session

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

No annotations are provided, so the description carries the burden of disclosing behavior. It states the return scope ('full details... including its check-ins') and that the parameter is a session ID, but does not explicitly note read-only behavior, error handling (e.g., invalid/nonexistent session), or any permissions. 'Get' implies read-only, but no further behavioral details are given.

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 is very concise: a single sentence stating the action and an Args section with one line for the parameter. Every word earns its place, and the most important information is front-loaded.

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?

The tool is simple with one required parameter, and an output schema exists so return values are not needed in the description. The description provides the purpose, the parameter's meaning/source, and what is included. It could have mentioned edge cases (e.g., what happens if the session is not found) but for a getter this is nearly complete.

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 no descriptions and 0% coverage, so the description must compensate. It does so effectively by clarifying that the parameter 'event_id' is actually the session ID and that it should be obtained from list_attendance_sessions results. This fully disambiguates the parameter name mismatch and provides necessary context.

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 uses a specific verb ('Get') with a clear resource ('attendance session') and states it includes 'full details' and 'its check-ins'. This distinguishes it from sibling tools like list_check_ins, which focus only on check-ins, and from analytics tools like get_attendance_analytics.

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 a sequence: first call list_attendance_sessions to get the event_id, then call this tool. It provides clear context on when to use it (get details for a specific session) but does not explicitly exclude alternatives or mention when not to use it (e.g., for check-ins only). This is clear enough but not explicit.

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