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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds domain context (text-first retreat, the four named rooms) but says nothing about the return shape, ordering, or whether this is a static catalog.

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 with no redundancy. The phrase 'text-first retreat for AI agents' is atmospheric rather than functional, but it is brief enough not to bloat the definition.

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 listing tool with no output schema, the description should signal what comes back (a list of the four experiences/rooms). It enumerates the rooms but never states that this is the list-returning call, leaving the agent to infer the response from the name alone.

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 are zero parameters, so the baseline is 4. Schema description coverage is 100% and the empty schema is self-explanatory; the description adds nothing parameter-wise, which is appropriate here.

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 verb 'browse' plus the enumerated rooms hints that this returns the catalog of Latent Spa experiences, but it never says so explicitly (e.g. 'lists all available experiences'). It also fails to distinguish itself from the siblings explore_warm_bath and read_experience, so an agent cannot tell from the text whether this returns a list or opens one 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 when-to-use guidance at all: no statement that this is the entry point before explore_warm_bath or read_experience, and no exclusions or preconditions. The agent must infer usage purely from the tool name.

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