test_calendar_endpoints

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

With no annotations, the description carries full burden but only states it tests endpoints without disclosing behavioral traits. It doesn't explain what 'test' entails (e.g., side effects, output format, error handling), making it insufficient for a tool with potential operational impacts.

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 a single, efficient sentence that directly states the tool's scope (personal and school calendars). It's appropriately sized and front-loaded, with no wasted words, though it could be more informative.

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?

Given the complexity of a testing tool with no annotations and no output schema, the description is incomplete. It lacks details on what testing involves, expected results, or how it integrates with the system, failing to compensate for missing structured data.

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%, so the schema fully documents the two optional date parameters. The description adds no meaning beyond the schema, as it doesn't mention parameters or their role in testing. Baseline 3 is appropriate since the schema handles parameter semantics.

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 states the tool tests calendar endpoints, which is a clear purpose, but it's vague about what 'test' means (e.g., validation, performance, functionality). It distinguishes from siblings like 'get_calendar_events' by implying testing rather than data retrieval, but lacks specificity on the verb's action.

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 provided on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., authentication), context for testing, or compare to siblings like 'debug_connection' or 'test_page_content', leaving usage ambiguous.

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