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

The annotations already declare a non-read-only, open-world mutation with destructiveHint=false. The description adds useful behavioral context: the item becomes publicly discoverable, the name and author are exposed with it, and the caller should verify those fields before invoking.

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 three tight sentences and front-loads the usage condition. Every sentence adds useful context: when to use it, how it differs from creation, and what data becomes public.

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 simple one-parameter mutation with annotations covering safety and openness, the description provides enough context to call it correctly. It could be slightly more complete by mentioning what happens if the vibescape is already public or how sharing can be undone, but those are minor gaps.

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?

There is only one parameter and schema description coverage is 100%, so the schema already explains that id is the share's six-character identifier returned by create_vibescape. The description does not add further parameter-level semantics, so the baseline score of 3 is appropriate.

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 states a specific action on a specific resource: listing a vibescape in the public gallery at vibresia.com/vibescapes. It also distinguishes this from creation by explaining that a vibescape is created unlisted and sharing is the separate act of publicizing it.

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?

It gives a clear trigger: use this when the vibescape should be publicly listed. It also clarifies the boundary with create_vibescape by noting creation is unlisted, but it does not explicitly name alternatives or describe when not to use it beyond that implied boundary.

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