preview_rename_bulk_job

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

With no annotations, the description must fully convey the read-only nature of the operation. The term 'preview' and 'before submitting' strongly imply that no files are renamed or jobs submitted, but the description does not explicitly state that it makes no changes or what happens on invalid inputs. It provides basic transparency adequate for a simple preview.

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 a single sentence of 14 words, front-loading the core purpose. No redundant or filler information.

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 has 6 parameters, no output schema, and no annotations, the description is too brief. It does not explain how the preview is presented (e.g., list vs. diff), what the parameters control, or what errors may occur. For a tool with this complexity, the description is insufficient.

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 input schema has 6 parameters with 0% coverage, and the description does not explain any of them. It hints at the existence of a rename preset and assets, but custom_text, start_number, global_start, custom_text_2 are left undefined. The description fails to compensate for the lack of schema descriptions.

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 uses a specific verb ('preview') and a specific resource ('filenames a rename bulk job will produce'), clearly distinguishing it from sibling tools like create_bulk_job or get_bulk_job. It states the tool's function precisely.

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 'before submitting it' gives clear temporal context for when to use this tool. However, it does not explicitly name alternative tools (e.g., create_bulk_job) that would actually submit the job, so a user could still be unsure when not to use this. The timing clue is helpful but not complete.

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