cloud_storage_upload_file

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

No annotations are provided, so the description carries the full burden. It mentions that it returns 'Success!!' or an exception message, which gives some behavioral insight, but lacks details on permissions, rate limits, file size constraints, or error handling. For a mutation tool with zero annotation coverage, this is insufficient.

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 well-structured with clear sections for Args and Returns, and it's front-loaded with the core purpose. However, the parameter mismatch adds unnecessary confusion, slightly reducing efficiency.

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 no annotations, no output schema, and a complex input schema with nested objects (100% coverage gap), the description is incomplete. It fails to explain the 'request' parameter or how it relates to the listed args, leaving significant gaps for a mutation tool.

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 1 parameter ('request') with 0% description coverage, and the description lists 3 parameters (absolute_file_path, object_name, bucket_name) that don't match the schema. This creates a contradiction and confusion, as the schema and description are misaligned, making parameter understanding impossible.

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 ('upload') and resource ('file to cloud storage'), making the purpose immediately understandable. However, it doesn't explicitly differentiate from sibling tools like cloud_storage_download_file or cloud_storage_delete_object, though the upload action is inherently distinct.

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?

No guidance is provided on when to use this tool versus alternatives. For example, it doesn't mention prerequisites like needing an existing bucket or how it relates to cloud_storage_create_bucket. The description only states what the tool does, not when or why to use it.

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