Publish a stored generation

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It explains the side effect: the resulting Roblox asset id is recorded against the generation, enabling analytics tracing. It also clarifies the network behavior (site sends its own stored copy) and what is not done (no download/re-upload). This is strong transparency for a publish action, though it could mention potential failure modes or permission requirements.

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, well-structured sentence that front-loads the core action and then adds necessary context. Every clause adds value: the source of the generation id, the mechanism (no download/re-upload), and the side effect (asset id recorded for analytics). No wasted words.

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?

Given the tool's moderate complexity (2 params, no output schema, no annotations), the description is quite complete. It explains the workflow (publish from history), the mechanism, and the downstream benefit (analytics tracing). It could be slightly more complete by mentioning what the response contains (e.g., the asset id) or any prerequisites like permissions, but it covers the essential context well.

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 already provides 100% coverage with descriptions for both parameters ('Game name or universe id' and 'Generation id from list_generations'). The description adds context by explaining the generation id's origin and the purpose of the asset id recording, but it does not add new syntax or format details beyond the schema. Baseline 3 is appropriate given the high schema coverage.

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 clearly states the action ('Publish an image already in a project's history to Roblox'), the specific resource (a generation identified by its id from list_generations), and the mechanism (the site sends its own stored copy, no download/re-upload). It distinguishes itself from sibling tools like upload_thumbnail and generate_thumbnail by focusing on publishing an existing generation to Roblox.

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 explains the context of use: it operates on a generation id from list_generations, implying a prerequisite step. It also clarifies what the tool does not do (nothing is downloaded or re-uploaded), which helps set expectations. However, it does not explicitly state when to use this tool versus alternatives like upload_thumbnail, though the distinction is implied by the generation id reference.

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