copy_adset

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

With no annotations, the description must disclose side effects. It states 'Creates a duplicate' but omits critical behaviors such as deep_copy defaulting to true (copying internal ads) and status defaulting to PAUSED, which significantly affect the operation's outcome.

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 redundant terms. It efficiently communicates the core action and key option.

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?

The tool has 5 parameters, no output schema, and no annotations, yet the description only covers the basic purpose. It does not explain important behavioral defaults like deep copy or paused status, leaving an agent without critical information for 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 coverage is 100% as every parameter has a detailed description including defaults and behavior ('If omitted, copies to same campaign'). The tool description adds no additional meaning beyond the schema.

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 identifies a specific action ('Copy'), a resource ('ad set'), and a key variable ('same or different campaign'), clearly distinguishing it from sibling tools like copy_campaign and copy_ad.

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 when duplicating an ad set and clarifies the same/different campaign option, but does not explicitly state when not to use it or mention alternatives like create_adset.

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