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

The description adds substantial behavior beyond the annotations: the operation is off-chain and gas-free, requires a two-step personal_sign flow, requires reusing the same timestamp and links, treats empty strings as clearing values, and propagates to the token page, cards, and API/NEXUS answers. This is rich context that the annotations do not provide.

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 dense sentence with high information density and no filler. It front-loads the core action and then packs in the signing protocol and scope. It is slightly run-on, but every clause earns its place.

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 tool's complexity (9 parameters, no output schema, two-step signing, chain ambiguity), the description covers the crucial workflow, scope, and propagation behavior. It does not specify the exact response format on the first call, but it tells the agent enough to invoke the tool correctly.

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 parameters. The description adds useful workflow context around signature/timestamp reuse and the meaning of empty values, but it does not add per-parameter meaning beyond what the schema provides. Baseline 3 is appropriate.

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 and resource: 'Set or update a launched token's Website / X / Telegram / Discord links.' It also distinguishes this tool from launch/read siblings by emphasizing off-chain, gas-free operation and creator-wallet signing, so an agent can identify it without opening other schemas.

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 gives clear when-to-use guidance: it works for every token whose on-chain socials are empty, including all V2-factory launches. It also explains the two-step signing workflow (call without signature, then again with signature using the same timestamp and links). It does not explicitly name alternatives or state when not to use it, so it stops short of a 5.

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