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

Annotations already mark the tool as not read-only and not destructive. The description adds critical behavioral context by disclosing the financial requirement (0.01 ETH buy-in) and the output (confirm_code and payment instructions), which is valuable beyond the annotations.

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 two sentences long, front-loading the core purpose and key requirement. Every sentence adds value with no redundancy, making it efficient for an agent to parse.

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 tool with 9 parameters and no output schema, the description covers the essential purpose, financial requirement, and output expectation. It could be more complete by explaining the confirm_code format or post-launch steps, but it provides sufficient context for an agent to proceed 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 baseline is 3. The description adds some context about the buy-in flow but does not elaborate on parameter meanings beyond the schema descriptions. It explains that creator_wallet must send ETH and that the buy-in funds are used, which provides moderate additional value.

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 tool requests a token launch on Base Mainnet via Clanker, specifying the MCP-exclusive launchpad and including key details like the 0.01 ETH creator buy-in. It distinguishes from siblings by being the only token-launch tool among financial actions.

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 explains the prerequisite of a 0.01 ETH buy-in and the distribution mechanics, providing clear context for when to use. However, it does not explicitly state when not to use or compare to sibling tools, though sibling tools are clearly different (financial operations vs. launch).

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