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

With no annotations, the description carries the full burden. It discloses two behavioral traits: provenance preservation and explicit invocation requirement. However, it does not mention side effects, cost, data scope, or whether it is read-only, leaving significant gaps.

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 extremely concise—two sentences with no filler. Every word contributes meaning, and the key points are front-loaded. It earns a top score for efficiency.

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 tool with three required parameters and no output schema, the description is too sparse. It does not explain what the comparison returns, how provenance is represented, or any constraints on inputs. The agent would have to guess at invocation expectations.

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%, so the description must compensate for the three undocumented parameters. It does not explain what 'query', 'notebook_a', or 'notebook_b' should contain or how they interact. The parameter names are self-explanatory but lack necessary semantic detail.

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 ('Explicitly compare two notebooks') and adds a distinctive detail ('preserving provenance by notebook') that helps differentiate it from siblings. It is specific about the resource and operation, though it doesn't explicitly name alternatives.

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 phrase 'Never invoked implicitly' gives a weak usage hint, but there is no explicit guidance on when to use this tool versus alternatives like 'research' or 'get_evidence'. No when-not-to-use scenarios or prerequisite conditions are provided.

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