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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds useful output context by enumerating what is returned (coin plan, reviewer notes, version statuses), which goes beyond the annotations, but it says nothing about permissions, error behavior, or whether all versions are always included.

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?

A single front-loaded sentence that lists the returned data with no filler. It is efficient and appropriately sized for a simple read tool, though the leading clause 'Where an experience stands' is less informative than the list that follows.

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 helpfully enumerates the returned content, which is the main completeness win. But it leaves the two required parameters entirely unexplained, a significant gap for an agent trying to call the tool correctly, even though the tool's complexity is low.

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%: both required parameters 'game' and 'key' have no descriptions in the schema, and the description never mentions them or explains what identifies an experience. The description completely fails to compensate for the undocumented parameters.

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 conveys that this returns an experience's status and associated data ('details, its coin plan, any note from the reviewers, and every version with its status'), so the resource is identifiable. However, 'Where an experience stands' is a vague noun phrase rather than a clear verb+resource statement, and it never explicitly distinguishes this read operation from siblings like list_experiences or create_experience.

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?

There is no statement of when to use this tool versus alternatives. With siblings including list_experiences (for listing) and create_experience, an agent might reasonably wonder whether this or list_experiences is the right call for inspecting an experience, and the description offers no routing guidance or preconditions.

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