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

Annotations already indicate destructiveHint=true and readOnlyHint=false, and the description adds meaningful context by stating that approving a staged update to published content applies that revision. This clarifies the nontrivial consequence of the decision. It does not, however, explain what happens when changes are requested, though that is less impactful.

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 sentences with no filler; the core decision action is stated first, followed by the most important side effect. Every sentence adds value and the structure is ideal for quick agent scanning.

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 mutation tool with a full schema and output schema available, the description covers the essential decision options and the publish effect. It does not detail the outcome of requesting changes, but the enum values and comment requirement in the schema cover most of what an agent needs. The definition is sufficiently complete for correct invocation.

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 100%, so the schema already documents all parameters. The description's mention of 'request changes' aligns with the comment requirement but adds no semantic detail beyond the schema, which is the baseline expectation.

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 clearly identifies the action as deciding on a pending content review via 'approve' or 'request changes', and explicitly describes the real-world consequence of approval ('applies that revision'). This distinguishes it from sibling tools like submit_content_review or list_content_reviews, which serve different stages of the review lifecycle.

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 phrase 'pending content review' implies this tool is used when a review is awaiting a decision, but it does not explicitly state when to prefer this over submit_content_review or other review-related tools. No exclusions or alternatives are named, so the guidance is only implied.

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