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

With no annotations, the description carries the full burden. It discloses that the upload will not be ingested, which is a useful behavioral trait. However, it does not state whether the deletion is irreversible, what happens to the underlying stored data, or any permission requirements, leaving gaps in transparency.

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, front-loaded sentence with no wasted words. Every word contributes to the meaning, and the structure is perfectly concise for the operation.

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?

For a simple one-parameter delete tool, the description covers the core action and the key distinction (not ingesting). It lacks context on how to find the upload_id and any side effects, but given the inherent simplicity and lack of output schema, the description is mostly complete.

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?

Schema description coverage is 0%, so the description must compensate. The only parameter, upload_id, is not explained beyond the obvious; the description says 'staged uploads' but does not clarify how to obtain or identify the ID. The description adds minimal semantic value over the schema's name/type.

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 ('Delete') and resource ('one of your staged uploads'), clearly distinguishing it from siblings like brainkb_ingest_upload (which would consume the upload) and brainkb_list_uploads (which only lists). The scope is unambiguously defined.

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 implies the use case (when you want to remove a staged upload without ingesting it) but does not explicitly mention alternatives or exclusions. It does not reference related tools like brainkb_list_uploads to obtain the upload_id, leaving some usage context implicit.

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