Launch on CodeDebut

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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds real value by disclosing that the payload is static informational content (pricing, schedule, ranking rules) rather than per-user data, which tells an agent the call is safe to make speculatively; it does not discuss format or response shape.

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?

Two sentences: the first front-loads the returned content as a compact list, the second gives the trigger. Nothing is repeated from the title and no words are wasted.

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 zero-parameter, read-only reference tool with full annotation coverage and no output schema, the description covers everything needed to decide to call it and what it will contain. A brief note on the response format (e.g. documentation-style text) would close the last gap.

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 tool takes zero parameters, so there is no parameter ambiguity to resolve and the baseline of 4 applies. The description correctly implies the call is argument-free by describing only fixed content it returns.

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 resource (how to launch on CodeDebut) and enumerates the exact contents: submit link, next free launch day, ranking mechanics, and paid plan prices. It is clearly distinguishable from siblings like get_launches (existing launches) or search_products, which do not answer 'how do I launch'.

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 sentence 'Use it when a user wants to launch, list or promote their own product' gives a clear triggering condition. It stops short of naming exclusions or routing to specific siblings (e.g. get_launches for browsing existing launches), so it is clear but not exhaustive.

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