upload_profiles

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Upload or update' implies a mutation, but it does not disclose whether updates merge or replace, whether authentication is required, rate limits, idempotency, or what the response looks like. This is a significant gap for a write operation.

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, efficient sentence with no redundancy. It communicates the core action and resource in a compact manner, which is appropriately sized for a simple tool, though it sacrifices substance for brevity.

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?

With no output schema, no annotations, and a schema with 0% descriptions, the description must provide comprehensive context to enable correct invocation. It does not. The agent has no idea how to structure the profiles array, what fields are required beyond the schema's minimal requirements, or what the response will be. For a mutation tool with one complex parameter, this is seriously incomplete.

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% (no descriptions in the schema properties), and the tool description adds no meaning beyond the field names. The single 'profiles' parameter accepts an array of complex objects, but the description does not explain the structure, required fields (like 'type' and 'identity'), or how to format profileData. The description fails to compensate for the schema’s lack of detail.

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 states a clear verb ('Upload or update') and resource ('user profiles in CleverTap'), which distinguishes it from event-related siblings like upload_events. However, it does not elaborate on the scope of 'profiles' (e.g., user identity vs. objectId), so it leaves some ambiguity but the core purpose is clear.

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?

There is no guidance on when to use this tool versus alternatives. It does not mention conditions like 'use this for profile creation/modification, use upload_events for events,' nor any prerequisite knowledge. The description does not help an agent decide between this and sibling tools beyond the resource name.

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