notlai_web_login

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

Without annotations, the description carries the full burden. It discloses that a local auth server is opened and a URL is provided, which is useful. However, it does not mention side effects (e.g., server lifecycle, browser interaction), required permissions, or what happens to authentication state.

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?

A single sentence containing all essential information with no extraneous words. Every phrase adds value.

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 no annotations, no output schema, and a single parameter, the description covers the basic action but lacks context about return values, error scenarios, or how the URL is delivered. It is minimally complete but leaves gaps.

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 coverage is 100% and the description adds the default value ('default: 9876') beyond the schema's description ('Local server port'), providing practical guidance for the optional parameter.

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 uses a specific verb ('start'), resource ('web-based login flow'), and explicitly mentions opening a local auth server and providing a URL, which clearly distinguishes it from sibling tools like 'notlai_login' (presumably non-web) and 'notlai_logout'.

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 implies use for web-based authentication compared to other login methods, but does not explicitly state when to use this over alternatives like 'notlai_login' or provide context like prerequisites or when not to use it.

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