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

Goes well beyond the annotations: discloses the on-chain verification criteria (Flaunch token, held by RevenueManager, original name/ticker), the EIP-191 personal_sign flow with two calls, the creator-wallet-only constraint on metadata edits, and the contents of the returned `share` object. This is exactly the kind of context the structured fields cannot carry.

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?

Front-loads the trigger condition and the effect, then layers verification, return value, and update flow in a sensible order. It is dense but slightly overlong, and the announcement-venue guidance is somewhat tangential to invoking the tool correctly.

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, yet the description explains the returned `share` payload (tagged link, draft post, image, posting rules), which is the key unknown for this tool. Combined with the verification and signature behavior, an agent has everything needed to call it 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 coverage is 100%, so the baseline is 3, but the description adds real meaning: `signature` is used in a two-call challenge flow (call without it to get the message, then call with it), and `description`/`website` only take effect for the creator wallet. It does not clarify the interaction between passing description/website without a signature, but the added value is clear.

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 a specific verb (register) and resource (launched token), states the concrete effect (gets a page on coinfactory.ai, appears in get_launched_tokens), and explicitly ties itself to the sibling build_token_launch_transaction as a prerequisite. An agent can distinguish this from get_launched_token/get_launched_tokens without opening any schema.

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?

Clear precondition ('after the launch transaction ... is mined') and a described two-step signature path for later metadata changes, including the creator-wallet-only restriction. It also states a follow-up expectation (announce the launch) but does not spell out when a call should be refused or what to do if verification fails, so it falls short of full when/when-not coverage.

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