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

With no annotations, the description bears the behavioral burden but only discloses one useful trait: cells are evaluated from original stored boxes. It doesn't disclose side effects of open/create/save, session statefulness, persistence, or failure behavior, which matter for a mutation-capable tool.

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 three sentences are compact and front-loaded, first establishing the resource and then listing actions. The final sentence about evaluation fidelity earns its place by explaining a non-obvious 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?

Even with an output schema present, this is a multiplexing tool with four parameters and no required fields, so the agent needs action-level parameter semantics and usage context. The description gives only a skim overview and leaves notebook, defaults, and state behavior unexplained.

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 action signatures map path and title to specific actions, adding meaning the schema doesn't convey, but schema coverage is 0% and the description omits the notebook parameter entirely. This partial guidance helps but leaves critical parameter relationships (especially around info/save and notebook) unexplained.

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 identifies the resource (.nb files on disk) and enumerates the supported actions (open/create/list/info/save/close), making the general purpose clear. It doesn't explicitly contrast with siblings like read_notebook_file or evaluate, so some inference is still needed to tell them apart.

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 given about when this session manager should be used instead of sibling tools, nor when one action should be preferred over another. The action list implies usage contexts but leaves the routing decision entirely to the agent.

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