save_token

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

With no annotations provided, the description carries full burden for behavioral disclosure. It mentions the action ('save') but doesn't explain where tokens are stored (e.g., memory, file, session), security implications, persistence duration, or error handling. This leaves significant gaps for a tool handling authentication credentials.

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, clear sentence with zero wasted words. It's front-loaded with the core action and resource, making it highly efficient 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 a tool handling authentication tokens with no annotations and no output schema, the description is insufficient. It lacks details on storage mechanism, security practices, token validation, or what 'future use' entails (e.g., which sibling tools might utilize it). This leaves critical context gaps for safe and effective use.

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%, with the single parameter 'token' documented as 'Your Kinde JWT token.' The description adds no additional parameter semantics beyond what the schema provides, so it meets the baseline for high schema coverage without compensating value.

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 ('save') and the resource ('Kinde authentication token'), making the purpose immediately understandable. However, it doesn't differentiate this tool from potential sibling authentication tools (like 'login' or 'logout') by specifying what makes saving tokens distinct from other auth operations.

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 with 'for future use,' but doesn't specify when to use this versus alternatives like 'login' (which might generate tokens) or 'refresh_billing_status' (which might use tokens). No explicit when/when-not instructions or prerequisite context about token acquisition are provided.

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