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

Annotations already declare destructiveHint=true, idempotentHint=false, and openWorldHint=false, so the safety profile is partly covered. The description adds useful scope ('one render version only, not translation siblings') and a confirmation requirement. However, it never explains the destructive aspect itself – whether publishing replaces an already-published version, and whether it can be undone – which is the key unknown for a destructive tool.

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 short sentences with zero filler; the core action is front-loaded and the scope caveat and confirmation rule follow in priority order. Every sentence carries non-redundant information.

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?

An output schema exists, so return values need not be described. But for a destructive, non-idempotent, two-parameter mutation with 0% schema coverage, the description leaves the parameters undefined and the destructive consequences unstated. It is minimally callable but not fully specified.

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 description coverage is 0%, so the description carries the full burden, and it largely fails. It references 'version' twice but never says it is a render version identifier/number or how to obtain it, and it never mentions the required projectUid parameter at all. An agent has to infer both parameters from names alone.

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 with scope: 'Publish one completed render version of a project.' The added 'does not publish translation siblings' narrows what the action touches. It does not name the obvious sibling alternative (unpublish_project), so differentiation is implied rather than explicit.

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?

Gives a concrete workflow constraint: 'Ask the user to confirm the exact version before making it public.' It also implies the precondition that the version must be a completed render. It stops short of telling the agent when to choose this over unpublish_project or translate_project.

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