Set the current task

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It accurately communicates the mutating nature of the operation and the important edge case of clearing via omission/null. It does not discuss failure modes or side effects, but the core behavior is transparent.

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. The main action is front-loaded, and the optional clearing behavior is clarified in a short clause without any filler.

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 one-parameter setter with no output schema, the description is complete enough for correct invocation: it states the primary action and the two ways to clear. It does not describe return values or error behavior, but neither is essential for this tool's basic use.

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 provides only the type 'string or null' with no parameter description. The description compensates fully by explaining that omitting taskId or passing null clears the current task, which is exactly the semantic meaning an agent needs.

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 and resource ('Sets the current task') and explicitly covers the clearing behavior when taskId is omitted or null. This clearly distinguishes the tool from siblings like sp_task_control_get_current and sp_task_update.

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 makes the usage context clear: call this to establish the current task, and omit or null taskId to clear it. It does not explicitly name alternatives or exclusions, but the intended use is easy to infer from the tool name and behavior.

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