unlink_session

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It indicates a mutating action by saying 'Remove', but it does not mention reversibility, permissions, behavior when no link exists, or side effects on the task. This is a significant gap for a destructive operation.

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, front-loaded with the verb, and contains no unnecessary words. It is perfectly concise and well-structured.

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's simplicity, the description covers the core function but lacks contextual guidance about preconditions, alternatives, or edge cases. The output schema may document return values, so that gap is acceptable, but the description is minimal overall.

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 description for task_id (0% coverage), so the description must compensate. It adds that the action is performed 'from a task', implying task_id identifies the target task, but it does not clarify ID format, how to obtain it, or invalid-ID behavior. Minimal compensation.

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 'Remove' with a clear resource 'AI session link' and target 'a task', making the tool's function immediately obvious. It also distinguishes from the sibling 'link_session', which is clearly the inverse operation.

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 usage when you need to remove a session link from a task, but it does not explicitly mention alternatives or when-not-to-use conditions. The sibling list provides some context, but the description itself offers no direct guidance.

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