medias_bulk_update_media_objects

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

Annotations already indicate the tool is non-read-only, idempotent, and non-destructive. The description adds no further behavioral context, such as whether it overwrites existing files, what happens to existing data, or any permission requirements. Given annotations already provide some safety cues, the description's lack of additional detail is a gap, but not a contradiction.

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 concise phrase, front-loaded with the key action. It is appropriately short for a simple tool, though it might be too terse to convey sufficient context. Structurally it is efficient with no filler.

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 performs a bulk update on an array of file/folder objects, but the description gives no information about what fields can be updated, the format of the update objects, or expected outcomes. This is a significant gap for an agent needing to construct a request. The openWorldHint suggests additional unknowns, and the absence of an output schema makes it harder to understand what to expect. The description is far from complete for a tool with this complexity.

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 describes all three parameters, so the description does not need to repeat them. However, the description does not clarify the structure of the 'filesToBeUpdated' array, which is the core parameter. With 100% schema coverage, the baseline is 3, but the description's lack of additional context about the array objects means it does not enhance understanding 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 states the tool updates files and folders in bulk. It clearly identifies the action (update) and the resource (files/folders), distinguishing it from singular updates through the 'Bulk' qualifier. However, it doesn't specify what properties can be updated or differentiate from other media tools beyond the bulk aspect.

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 provides no explicit guidance on when to use this tool versus alternatives. It does not mention any prerequisites, exclusions, or conditions that would help an agent decide between this and the singular update tool. An agent must infer from the name.

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