Check SAP Authentication

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 authentication and session association but fails to describe critical behaviors: what happens on successful/failed validation, whether this creates persistent sessions, what permissions are checked, or any rate limits. The description is too vague for a security-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 extremely concise with just two sentences. The first sentence states the purpose, and the second provides the basic usage instruction. There's no wasted language or unnecessary elaboration, making it efficiently front-loaded and easy to parse.

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 an authentication tool with 4 parameters (including a nested object), no annotations, and no output schema, the description is insufficient. It doesn't explain what the tool returns, what authentication state changes occur, or how it integrates with other SAP tools. The complexity of the context parameter with anticipated operations and session types deserves more explanation than provided.

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 100%, so the schema already documents all parameters thoroughly. The description only mentions the session_id parameter, adding minimal value beyond what the schema provides. It doesn't explain the relationship between parameters or the overall authentication flow, maintaining the baseline score for high schema coverage.

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 the verb 'validate/associate' and the resource 'authentication session'. It specifies the required parameter (session_id) and the action (authenticate). However, it doesn't differentiate this authentication tool from other SAP-related tools in the sibling list, which mostly focus on data operations rather than authentication.

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 minimal guidance: 'Call with session_id to authenticate.' It doesn't specify when to use this tool versus other authentication methods, what prerequisites exist, or when not to use it. No alternatives or contextual triggers are mentioned, leaving the agent with insufficient guidance for optimal tool selection.

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