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

The annotations already mark this as a non-read-only, open-world, non-idempotent, non-destructive action. The description goes further by specifying that it creates a draft, returns a private review link, requires the maker to sign in and publish, and that no public launch or charge occurs on this call, adding meaningful transparency beyond the flags.

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?

Four sentences, front-loaded with the action verb, each providing new information: purpose, process, return value, and side-effect clarity. No filler or redundancy.

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?

With no output schema, the description still communicates the key output (a private review link) and the complete lifecycle (draft → maker review → publish). Combined with the annotations, the agent has enough information to invoke the tool safely and understand what will and won't happen.

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 80%, so the baseline is 3. The description adds only the high-level note that the listing is drafted (name, tagline, description, story, pricing, categories), which informs the agent that some fields are auto-generated, but it does not add per-parameter semantics beyond what the schema already provides.

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 opens with 'Starts a launch for a product URL,' naming a specific verb and resource, and clarifies the workflow (reads site, drafts listing, returns review link). It is clearly distinct from the read-only sibling tools (get_*, search_products), which focus on viewing or querying rather than creating.

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 gives clear context that this is the action for launching a product and even notes the safe side effects ('Nothing goes live and nothing is charged'). However, it does not explicitly contrast with sibling tools or state when to prefer alternatives; the distinction is implied by the tool name and sibling set.

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