ethora-user-login

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 ('Login') but doesn't specify what happens upon login (e.g., session creation, token return, error handling for invalid credentials). For a security-sensitive tool, this lack of detail is a significant gap.

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 function without unnecessary words. It's front-loaded with the core action, 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 complexity of a login operation (involving authentication, potential session management, and error cases), the description is insufficient. With no annotations and no output schema, it fails to explain what the tool returns (e.g., a token, user data) or behavioral aspects like rate limits or security requirements, leaving critical gaps for an AI agent.

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 description adds minimal semantic context beyond the input schema, which already has 100% coverage with clear descriptions for 'email' and 'password'. It implies these parameters are for authentication but doesn't provide additional details like format constraints or security considerations, meeting the baseline 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 action ('Login to Ethora') and the mechanism ('with email and password'), making the purpose immediately understandable. However, it doesn't differentiate this tool from its sibling 'ethora-user-register', which likely also involves user credentials but for a different purpose.

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 like 'ethora-user-register' for account creation, nor does it mention prerequisites (e.g., needing an existing account) or exclusions. It simply states what the tool does without contextual usage information.

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