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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered. The description adds useful behavior beyond that: results are ordered newest first and cover all three actor classes. It does not mention retention window, whether unpaginated calls truncate, or that no time-range filter exists.

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?

A single compact sentence with the key scoping facts front-loaded and no filler. The informal verb 'asked' is slightly ambiguous (asking questions of a notebook) but is understandable in context.

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?

With six optional filter parameters and no output schema, the description should clarify at minimum the shape of a log entry and the fact that there is no date-range parameter, which an agent will likely look for on an audit-log tool. Ordering and actor coverage are covered, but paging, valid action values and result contents are not.

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 coverage is only 33%, so the description carries real weight, and it does partly compensate: 'opened, asked or changed' clarifies what the action filter selects, and 'people, apps and agents' maps onto the actor_type enum. It says nothing about limit/offset paging behavior or valid action values, leaving half the parameters undocumented in both places.

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 names the resource (the notebook access log) and characterizes its contents precisely: who opened, asked or changed notebooks, covering people, apps and agents, ordered newest first. The verb 'get' is only implied, and it does not distinguish itself from nearby siblings such as get_knowledge_notebook_access or get_app_knowledge_access, but an agent can still tell what data comes back.

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?

There is no explicit guidance on when to call this versus the several adjacent access/audit tools (get_knowledge_notebook_access, get_app_knowledge_access, get_knowledge_redaction_log). The only implicit signal is 'newest first', which hints at a recent-activity use case, but nothing states prerequisites or exclusions.

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