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

Annotations already declare readOnly, idempotent, non-destructive, and closed-world behavior, so the safety profile is covered. The description adds that a human signs the wallet connection and credentials are scoped, which is meaningful behavior, but 'wallet-ref duct' and 'security bar unchanged' are vague and no return format is described.

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?

One front-loaded sentence with a compact list; no wasted words. The unexplained 'wallet-ref duct' slightly reduces precision.

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?

For a no-param help tool with annotations, it sketches the onboarding sequence, but the steps are compressed and one phrase is unclear. It does not indicate whether it returns live instructions or static text, and there is no output schema to fill that gap.

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 tool has zero parameters and schema coverage is vacuously 100%, so parameter semantics are not at issue. Baseline 4 is appropriate; the description adds no parameter meaning and needs none.

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?

Names the resource (MemeSwap onboarding) and enumerates concrete steps, so an agent knows this is a help/how-to tool. It does not explicitly distinguish itself from memeswap_trading_help or say whether it returns static docs or live state, but the scope is 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 when-to-use guidance, no alternatives, no prerequisites. It implies you consult it before onboarding, but does not say to call it before set_profile/set_avatar or what to do if onboarding is already complete.

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