notebook_kernel_control

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

Annotations only declare readOnlyHint=false and destructiveHint=false; they do not tell the agent that restart/shutdown discard all in-memory variables and kernel state. The description adds no such behavioral context, nor any note on permissions or what the caller observes afterward. With annotations providing minimal coverage, the description leaves a real gap for a state-altering 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?

One sentence, front-loaded with the verb set, with the action enumeration in parentheses. No filler and nothing buried.

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 two-parameter tool with no output schema, the description covers the action domain adequately, and the annotations carry the (thin) safety profile. It still omits notebook_id semantics and the state-loss consequences of restart/shutdown, which an agent needs to choose this tool responsibly.

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% and the action parameter has no enum in the schema, so naming 'action: interrupt | restart | shutdown' in prose is genuinely additive. However, notebook_id is left entirely undefined, and there is no indication of what notebook_id should reference or the failure mode for an unknown id.

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 gives a concrete verb set (Interrupt, restart, shut down) against a specific resource (the notebook's kernel), and even enumerates the accepted action values. It is clearly distinguishable from notebook_kernel_start and notebook_kernel_state by implication, though it never names those siblings explicitly.

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 action list conveys what operations exist but not when to use each one (e.g. interrupt vs restart when a cell is stuck, or shutdown when freeing memory). No alternatives, prerequisites, or when-not-to-use conditions are stated.

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