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

Annotations already declare readOnlyHint=false, destructiveHint=true, idempotentHint=true, and openWorldHint=false, so the safety profile is covered. The description adds the genuine auth requirement ('Admins only'), which annotations do not express, but it says nothing about what the destructive write overwrites, how expected_revision conflicts are handled, or how idempotency_key deduplication behaves.

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?

Ten words with no filler, but the brevity here reflects under-specification rather than economy; the one sentence is essentially the title repeated. Nothing is front-loaded because there is nothing substantive to front-load.

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?

This is a destructive, idempotent, admin-gated mutation with 6 parameters, nested objects, and no output schema, and the description supplies only the permission gate. An agent cannot determine revision-conflict behavior, what content is replaced, or how to populate any of the required/non-required fields.

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 (idempotency_key, template_id, content_ast, expected_revision, request_id, fill_ins), so the description carries the full burden and largely fails it. The phrase 'and its fill-ins' loosely maps to the fill_ins array and 'draft' hints at content_ast, but template_id, expected_revision, idempotency_key, and request_id are given no meaning or format.

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 permission gate 'Admins only'; there is no statement of when to choose this over the create/publish/copy/archive siblings in the same library-documents family. No prerequisites such as working from an existing draft or revision are given.

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