upload_bulk_attachments

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions uploading files and an optional cashflow type, but fails to disclose critical traits like required permissions, rate limits, file format restrictions, or whether the operation is idempotent. For a bulk mutation tool, this lack of detail is a significant gap.

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 front-loaded with the core purpose, followed by clear sections for Args and Returns. Every sentence earns its place, with no redundant information, making it efficient and easy to parse for an agent.

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 and no output schema, the description provides basic purpose and parameter semantics but lacks behavioral details (e.g., error handling, response format). For a bulk upload tool with mutation implications, this is minimally adequate but leaves gaps in understanding how to use it effectively.

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 meaningful context for both parameters: 'file_paths' is explained as 'List of paths to files to upload', and 'cashflow_type' is clarified with its optional nature and allowed values (INCOME or EXPENSE). Since schema description coverage is 0%, this compensates well, though it doesn't specify path format (e.g., local vs. remote).

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 tool's purpose with a specific verb ('Upload') and resource ('multiple file attachments in bulk'), distinguishing it from siblings like 'create_attachment' (singular) and 'list_attachments' (read-only). However, it doesn't explicitly differentiate from 'link_attachment_transaction', which might involve attachments but with a different focus.

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 like 'create_attachment' (for single uploads) or 'link_attachment_transaction' (for linking existing attachments). The description lacks context about prerequisites, such as whether files must be pre-processed or if there are size limits, leaving the agent with no usage direction.

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