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

The description adds behavioral detail beyond the annotations by specifying that calling it on a task already in the sprint is a no-op. This is useful context beyond the idempotentHint annotation, which only states idempotency without describing the exact outcome. It does not contradict any annotations.

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 sentence that is front-loaded with the usage condition ('Use this when...') and includes the idempotency caveat. There is no fluff, and every word contributes to understanding the tool's purpose and behavior.

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?

For a simple tool with two required parameters, no output schema, and no nested objects, the description covers the core purpose and a key behavioral nuance (idempotent no-op). It does not describe what happens if the task or sprint does not exist, but that may be acceptable for a straightforward operation. The description is largely complete for an agent to call the tool correctly.

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 coverage is 0%, and the description does not mention either parameter (taskId or sprintId) at all. The parameter names are self-explanatory, but the description adds no additional meaning or clarification about their format or purpose beyond what the schema's property names imply. With zero coverage, the description should compensate but fails to do so.

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 clearly states the action: 'pull an existing task into a sprint'. It specifies the verb and resource, and implies the task is existing, distinguishing it from creation. However, it does not explicitly name alternative sibling tools like remove_task_from_sprint or move_task, so it lacks explicit sibling differentiation.

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 gives a clear context for use: 'when the user wants to pull an existing task into a sprint'. It does not mention when not to use it or provide alternatives, but the instruction is unambiguous enough for an agent to know when to invoke it.

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