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

With no annotations, the description carries the full burden and does so: nothing can be signed or spent, the image, fee share, initial buy and all signatures stay with the person, invalid fields are refused with a reason, and the submitted text is shown verbatim to the person before anything happens. That is exactly the mutation-safety disclosure an agent needs.

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 sentences, front-loaded with the action, then the inputs/outputs, then the safety envelope. Dense but every sentence carries information; the final two clauses about review are somewhat repetitive with the earlier no-signing statement.

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?

No output schema exists, so the description must describe the return — it does (launcher link plus next steps). With no annotations it also covers the safety and failure profile, leaving nothing an agent needs missing.

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. The description goes beyond it by naming the required trio and flagging website and X account as optional, and by signaling that server-side launch rules can reject a field — a constraint the schema only implies through maxLength.

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?

States a specific verb and resource ('Draft a Bags token launch with VaultBags preconfigured') and immediately scopes it as draft-only ('for a person to finish and sign'). This cleanly separates it from every sibling, which are all read-only getters/verifiers.

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 about when to use it and what the handoff looks like: gather name/ticker/description, receive a launcher link plus next steps for the person to sign. No alternative tool is named, but no sibling competes for this job, so the missing exclusion is minor.

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