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

With readOnlyHint=true and openWorldHint=false already declaring a safe, closed read, the description adds substantial context about the return payload: settings, artwork counts, trait rarities, metadata pin status, deployment gaps, risk score, and on-chain write cost. That is valuable for an agent to know what data it will receive, though it omits error or empty-state behavior.

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 front-loaded sentence that leads with the core purpose and then packs in return details without filler. It is dense but every clause carries information, though a colon-separated list might read more easily as bullets.

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 read-only tool with no output schema, the description carries the burden of explaining what is returned and does so comprehensively—covering settings, art, metadata, readiness, risk, and cost. It stops short of describing error cases or access confirmation, but is otherwise complete.

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 single draftId parameter has 100% schema description coverage, and the schema explains where to obtain the id (prepare_launch, my_launches). The main description adds no further parameter detail, so the baseline 3 applies.

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 specifies a single launch draft and enumerates its full contents, clearly distinguishing its scope from the plural my_launches list tool. However, it does not explicitly name the sibling to use for listing, leaving that inference to the tool name and param description.

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 implies use when full details of a draft are needed—e.g., checking 'what's left before it can deploy'—but gives no explicit when/when-not guidance or named alternatives. The param description mentions prepare_launch and my_launches, but the main description does not route the agent.

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