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

Annotations already declare it is non-destructive, idempotent, and closed-world; the description adds genuinely new behavioral facts beyond those, namely that the entire subtree moves with the page and that a page can never be moved inside itself. It does not address permissions or failure modes, so it stops short of a 5.

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 dense sentence that front-loads the action and then defines the two optional parameters in order. Every clause carries information, though the nested parentheticals make it slightly harder to parse than it could be.

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 3-parameter mutation tool with full annotation coverage and no output schema, the description supplies the key behavior an agent needs (subtree movement, root default, self-nesting prohibition). Only the id parameter's meaning is left implicit.

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 carry the parameter burden and largely does: parent_id 'none' means the book root, quote index '0 the first' defines ordering among siblings, and id is understandably the page to move. The id parameter is only implicitly explained, keeping it from a 5.

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 (move) and resource (a Playbook page), scoped to relocation within the book, which cleanly distinguishes it from siblings like delete_a_playbook_page, add_playbook_pages, and write_a_playbook_page.

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 description implies usage (reorganizing where a page sits in the book) and no sibling performs the same move, but it never explicitly states when to use this versus alternatives such as delete/re-add.

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