arvan_s3_sync_local_dir

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

Minimal disclosure of behavior. Annotations only show non-readOnly and non-destructive, but description doesn't explain upload behavior (e.g., overwrite vs skip existing, authentication requirements, or whether it creates missing buckets).

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?

Single sentence, immediate action, no fluff. Ideal conciseness for a straightforward tool.

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 description does not cover essential context for safe usage: no mention of file overwrite behavior, bucket existence prerequisites, or return values. Inadequate for a 4-parameter upload tool with no output schema.

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 description adds no meaning to the parameters. With 0% schema description coverage, the description should explain key parameters like 'prefix' and 'acl', but it does not.

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 action (upload), the source (local directory), the destination (bucket), and the recursive behavior. It effectively distinguishes from single-file operations like arvan_s3_put_object.

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 on when to use this tool versus alternatives. There is no mention of when to prefer this over arvan_s3_put_object or other sync methods.

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