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

With no annotations provided, the description must carry the behavioral burden. It explicitly discloses that build endpoints return unsigned transactions the agent must sign itself, which is a critical behavior for safe invocation. It also mentions the return value (cost config + feed). It doesn't cover rate limits or auth needs, but the signed-transaction disclosure is meaningful and credible.

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 short, front-loaded sentences with no filler. The purpose, return payload, and critical build behavior are all present in a compact format.

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?

The description is incomplete relative to the schema. It claims a launch action but provides only an optional 'mint' parameter, which is for reading a single token's detail. An agent cannot tell how to initiate a launch from the given definition, so the tool is functionally incomplete. The lack of an output schema further means the agent must infer return shape from the partial description.

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 schema has one optional 'mint' parameter with a complete description, so baseline is 3. The description adds extra meaning by clarifying that omitting mint returns the live cost config and recent launch feed, which goes slightly beyond the schema text. However, the claimed launch action has no corresponding parameter in the schema, so the description fails to explain how to paramere a launch.

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 states a specific verb 'launch' with a clear resource ('a token on X1') and a read mode ('read what has been launched'). This distinguishes it from sibling tools like swap_build or token lookup: 'launch' is a distinct concept. However, it doesn't name an explicit alternative, so it falls just short of best-in-class clarity.

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?

Very little guidance is given about when to use this tool instead of others. The note that build endpoints return unsigned transactions implies a separate signing step, but it does not state when to choose launchpad over e.g. swap_build or token_lookup, nor does it give explicit when-not-to-use criteria. The agent is left to infer usage context.

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