copy_ads

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

Discloses key behaviors: copies are created PAUSED, Reddit creates a new duplicate promoted post per copy, optional click_url rewriting, and partial failure handling. Adds value beyond annotations which are minimal.

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?

Four sentences, front-loaded with the core purpose, no wasted words.

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?

Covers main behaviors and parameters, though no output schema is provided. Could mention that original ads remain unchanged, but implied.

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?

Adds context for utm_overrides and source_ad_ids (partial failure) beyond the 100% schema coverage, but the parameter descriptions in schema already cover basics.

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 states the verb 'duplicate' and the resource 'ads into another ad group', distinguishing it from sibling tools like create_ad or pause_items.

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?

Provides context that copies are created paused and that one bad source ID doesn't abort the rest, but does not explicitly compare to alternatives or state when not to use.

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