bulk_rename_objects

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

No annotations are provided, so the description carries full burden. It only states the basic action without disclosing atomicity, error handling, limitations on object count, required permissions, or effects on ad delivery, leaving significant behavioral gaps.

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?

The description is concise with 5 lines, starting with a clear summary sentence and a structured parameter explanation. It is efficient but could be slightly more front-loaded.

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?

Given the tool is a bulk operation with one parameter and no output schema, the description lacks return value info, error handling, rate limits, and behavioral details, making it incomplete for confident use.

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?

The schema provides only a string type with 0% coverage. The description adds the exact JSON array format, including object structure and allowed object_type values, which is essential for correct invocation 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 clearly states 'Rename multiple Meta Ads objects in one call', identifying the specific verb (rename) and resource (Meta Ads objects), and emphasizes the bulk aspect, distinguishing it from individual rename operations.

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 for bulk renames via 'multiple...in one call', but does not explicitly contrast with sibling tools like update_ad, update_adset, or update_campaign, nor provide when-not-to-use or alternative guidance.

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