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

The description claims 'Logs in' but does not disclose side effects (e.g., whether it sets a global session), error conditions, or required permissions. With no annotations, the burden is on the description, which fails to provide adequate behavioral context.

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 sentence with no filler, which is efficient, but it lacks necessary detail. It is concise but not sufficiently informative.

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 low schema coverage, no annotations, and no output schema, the description is incomplete. An AI agent needs to know prerequisites, side effects, and error handling for a login tool, which are missing.

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 schema has one optional parameter 'token' with 0% description coverage. The description mentions 'configured token' but does not clarify if this refers to the parameter or a pre-configured secret, nor does it explain format or origin. This adds minimal value beyond the schema.

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 ('Logs in') and resource ('Discord using the configured token'), but does not distinguish from sibling tools. However, login is a distinct operation compared to message sending or channel management, so the purpose is reasonably clear.

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?

No guidance is provided on when to use this tool, prerequisites (e.g., token must be valid), or that it should typically be called once at the start. There is no mention of alternatives 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.
