create_study_task

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

With no annotations, the description must disclose behavioral traits. It does not mention the idempotency_key parameter's behavior, duplicate handling, return value, or side effects. The only non-essential detail is the date format requirement, which is not behavioral.

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 short, direct, and front-loaded with the core action. It has no redundant words, but it is under-specified. It earns a 4 for efficiency, though not a 5 because it omits essential context.

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 tool has 4 parameters, 0% schema coverage, and no annotations, the description is insufficiently complete. It only covers due_at and ignores idempotency_key and other behavioral aspects. An output schema exists, which may cover return values, but the input semantics remain incomplete.

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 0%, so the description must compensate. It adds value for due_at by specifying ISO 8601 format, but leaves title, description, and especially idempotency_key unexplained. The idempotency_key parameter is non-obvious and requires semantic clarification.

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 'Create a study task' uses a specific verb and resource, clearly distinguishing it from sibling tools that search, get, list, or update. The purpose is unequivocal.

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. The description simply states the action without any contextual cues, exclusions, or references to siblings like update_study_task_status. The ISO 8601 hint is parameter-specific, not usage guidance.

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