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

With no annotations provided, the description carries full burden but only states the action without behavioral details. It doesn't disclose what happens on success (e.g., session creation, token return), failure modes, security implications, or side effects like session persistence. This is inadequate for a critical authentication tool.

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, focused sentence with no wasted words. It's front-loaded with the core action and target, making it easy to parse quickly. This is an example of efficient communication for a simple 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?

Given the complexity of authentication (a security-critical operation) and the lack of annotations and output schema, the description is incomplete. It doesn't explain what the tool returns (e.g., session ID, success status) or behavioral expectations, leaving significant gaps for the agent to operate safely.

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 input schema has 0 parameters with 100% coverage, so no parameter documentation is needed. The description doesn't add parameter semantics, but that's acceptable here since there are no parameters to explain. A baseline of 4 reflects that the description doesn't need to compensate for missing schema info.

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 'Authenticate with ABAP system' clearly states the action (authenticate) and target (ABAP system), which is better than a tautology. However, it doesn't specify what type of authentication (e.g., session-based, token-based) or distinguish it from sibling tools like 'logout' or 'reentranceTicket' that might handle related authentication flows.

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 no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., required credentials), when authentication is needed in a workflow, or how it relates to tools like 'logout' or 'reentranceTicket'. This leaves the agent to infer usage context.

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