notebook_notes

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

No annotations are provided, so the description carries the full behavioral burden. It reveals nothing about the destructive nature of 'delete', whether notes persist across sessions, permission requirements, or how the default 'Agent Note' title and empty content behave.

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 front-loaded sentence with no waste, but the brevity here is under-specification rather than economy — the action list consumes the space that should have gone to per-action parameter requirements.

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 6-parameter, 5-action mutating tool with no annotations and no schema descriptions, the description is far too thin; the output schema covers return values, but nothing tells the agent which inputs are valid for which action or what delete does.

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% across 6 parameters. The description only enumerates legal values for `action`; it never explains note_id, notebook_id, workspace_dir semantics, or which fields apply to which action — a critical gap for a multi-action tool with zero required params.

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?

States a specific verb and resource: managing persistent notes inside a Gemini Notebook, with the action enumeration clarifying it is a multi-operation note CRUD tool. This distinguishes it from notebook-level siblings like notebook_create or notebook_get, though it doesn't explicitly say so.

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 implies usage modes, but there is no guidance on which parameters each action needs, no prerequisites, and no steering among the many notebook_* siblings (e.g., when to use notebook_notes vs notebook_attach or notebook_query).

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