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

Annotations already declare the destructive, non-readonly nature, lowering the bar. The description adds which fields get set, but omits what gets overwritten on existing publications, and says nothing about the advertiserProvided flags, guideline attachment, or the five contentInput variants. Useful but materially incomplete for a destructive mutation.

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 filler. It is efficient, though the brevity is partly what leaves coverage gaps elsewhere.

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 7-parameter destructive mutation with a nested anyOf parameter and no output schema, the description covers only the three simplest fields. It does not describe the contentInput branch selection, guideline attachment, or expected effects, which is a significant shortfall.

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 only 29%, so the description must compensate — and it only maps to contentInput.url, contentInput.anchor, and publishAt. It ignores publicationIds, orderGuidelines, attachedGuidelineTypes, and the entire multi-branch contentInput structure (googleDocsURL, keywords, topic, imageQuery, visibilityPrompts), leaving the agent to reverse-engineer the most complex parameter from the schema alone.

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 concrete verb ('Set') and concrete resources (target URL, anchor text, publication date) scoped to 'publications in an order,' which lets an agent distinguish it from siblings like place-order or get-order. It stops short of explicitly naming which sibling to prefer, so it lands at 4 rather than 5.

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?

There is no statement of when to use this tool versus alternatives, no prerequisites, and no sequencing relative to place-order or update-cart. The agent must infer the workflow context from the tool name alone.

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