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

Annotations already cover the safety profile (readOnlyHint=false, destructiveHint=false, idempotentHint=true, openWorldHint=false), so the bar is lower. The description's one genuine addition is the admin-only authorization requirement, which is real context beyond the annotations, but it says nothing about where the copy lands, whether the source is left untouched, or any limits.

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?

Two short sentences with no padding and the action front-loaded, but the text is a verbatim restatement of the title, so it is under-specified rather than genuinely tight. Nothing is wasted, but nothing beyond the title is contributed either.

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 four-parameter mutation tool with no output schema and no parameter documentation anywhere, the description is far too thin. An agent cannot tell what the returned draft contains, whether the copy is nameable, or what happens on repeat calls, without opening the schema.

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?

Four parameters with 0% schema description coverage, and the description explains none of them. It only loosely hints that a source document identifier (template_id) is involved; the purpose of idempotency_key, the optional name override, and request_id are left entirely unexplained 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?

Tautological: description restates name/title.

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 only usage signal is the 'Admins only' restriction; there is no statement of when to copy versus create a fresh library document or update an existing draft, and no preconditions (e.g. source must be published/exist). An agent must infer selection logic from the name alone.

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