authenticate

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. It states the tool authenticates but doesn't describe what happens upon success (e.g., returns a token, sets a session), failure behavior, rate limits, security implications, or persistence of authentication. For a critical security tool with zero annotation coverage, this is a significant gap in transparency.

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 that directly states the tool's purpose and parameters without any fluff. It's appropriately sized and front-loaded, with every word earning its place, making it easy to parse quickly.

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's complexity (authentication with security implications), lack of annotations, and no output schema, the description is incomplete. It doesn't explain return values, error handling, or behavioral traits needed for safe and effective use. The description should do more to compensate for these gaps, especially for a tool that likely enables other operations.

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 both parameters ('email' and 'password') well-documented in the schema. The description adds minimal value beyond the schema by mentioning these parameters generically, but doesn't provide additional context like format requirements or security notes. Baseline 3 is appropriate when the schema does the heavy lifting.

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 ('Authenticate') and target ('with StashDog'), specifying the authentication method ('using email and password'). It distinguishes this as an authentication tool, which is different from all sibling tools that manage data or perform searches. However, it doesn't explicitly contrast with potential alternative authentication methods (e.g., OAuth), keeping it from a perfect score.

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., needing authentication before other operations), exclusions, or how it relates to sibling tools like 'manage_users'. Usage is implied only by the tool's name, with no explicit context provided.

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