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

Beyond the annotations, the description discloses the 150,000-character read limit, that the workspace's model spend is consumed, and that nothing is persisted ('Nothing is written'). These are meaningful behavioral facts (cost, limits, no side effects on data) that the annotations alone don't convey.

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 core action is front-loaded in the first clause and the rest strings supporting details in one dense paragraph with minimal waste. It is a bit packed, but every sentence earns its place.

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 no output schema, the description still explains what is produced (proposed pages of facts placed among the book's pages) and the cost/limits of the call. It is complete enough for an agent to invoke correctly, though the shape of the proposal result could be clearer.

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 carries the burden and covers all three params: text is the document body with a char cap, hint describes what the document is, and place_under accepts a page id, 'root', or empty to auto-place. This compensates well for the absent schema descriptions, though it doesn't specify formats like how page ids look.

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 specific verb+resource - reading one company document and proposing Playbook pages - and explicitly contrasts with add_playbook_pages ('Nothing is written: add the pages you keep with add_playbook_pages'). An agent can distinguish this from the sibling write tool without opening either schema.

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?

It states the operating context clearly ('as the Playbook's Import does') and routes the agent to add_playbook_pages for the follow-up write step. What's missing is guidance on when NOT to use this versus other document-reading tools, but the key propose-vs-write decision is explicit.

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