Reserve Drop upload

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

The description discloses the core behavior (reserving a slot) and the API endpoint, but does not elaborate on potential side effects like slot expiration or idempotency. The openWorldHint annotation already warns of unknown side effects, so the description adds some value but not rich detail.

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 extremely concise, using two sentences to convey the purpose and the follow-up action, with no redundant information.

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 the tool has 11 parameters (2 required) and no output schema, the description is insufficient. It fails to mention which parameters are required, what the response contains, or how the reservation integrates with the overall upload flow beyond naming the next step.

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 provides no information about any of the 11 parameters, despite the schema description coverage being only 36%. It only mentions the returned 'upload id' from the next step, leaving all parameter meanings unexplained.

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 ('Reserve an upload slot') and the specific resource (POST /api/v2/drop/uploads), and it explicitly names the next step (drop_upload_content), distinguishing it from sibling upload tools.

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 clear usage context by instructing to call drop_upload_content next, indicating this is the first step in a two-step upload flow. However, it does not explicitly mention when not to use this tool or list alternative approaches.

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