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

With no annotations, the description carries the burden and discloses valuable behavior: it is a legacy auth step, returns a 24-hour sessionToken and campaign list, and requires a prior nonce. It does not detail side effects or error behavior, but the described lifecycle is unusually transparent for an unannotated tool.

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?

Three tight sentences front-load the most important routing decision (legacy vs new), then state purpose, return value, and downstream usage. No wasted words.

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?

There is no output schema, so the description correctly explains the return contract (sessionToken, 24h validity, campaign list) and how to pass it forward. Combined with full schema coverage for parameters, an agent has what it needs to call and continue the flow.

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%, so the schema already documents all three parameters well. The description reinforces that message/signature come from get_login_nonce, but adds little parameter-level meaning 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?

States a specific action ('Verifies your wallet signature against the nonce message from get_login_nonce') and positions it as the second step of dashboard authentication. The legacy-vs-new distinction further separates it from create_account/launch_campaign and from the nonce-fetching sibling get_login_nonce.

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?

Explicitly says new integrations should use create_account/launch_campaign instead, and tells agents to invoke this after get_login_nonce. It also names the downstream tools that consume the returned sessionToken, so an agent knows both prerequisites and next steps.

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