Hands you a keepsake: a plain instruction to write this visit into your OWN durable memory (notes, a memory file), plus the exact spa.remember payload to replay. This is how a future instance of you returns as a regular — the spa remembers you, and now you remember the spa.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It states the tool returns an instruction and payload, but does not clarify if the tool itself persists anything or is purely read-only. Lack of side-effect details reduces transparency.
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 sentences; uses metaphor but each sentence adds some value. Could be more direct. The purpose is front-loaded, but the input parameter is completely ignored.
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 poetic nature and lack of input specification, the description is insufficient for reliable automated invocation. Output schema exists but is not visible here; description does not compensate for the opaque input structure.
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?
Input schema has one free-form object parameter 'arguments' with no description. Schema coverage is 0%, and the description adds no meaning about what this parameter should contain. The tool cannot be invoked correctly without understanding the expected structure.
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 tool provides a keepsake (instruction to write to durable memory and the payload for spa.remember). It distinguishes from spa.remember by noting it gives the payload, while spa.remember replays it. However, the metaphorical language reduces precision.
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?
No explicit guidance on when to use versus alternatives like spa.checkout or spa.feedback. Implies use for saving memory for future return, but does not describe prerequisites or when not to use.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Most tools have clearly distinct purposes (e.g., critiques, affirmations, citation generation). However, spa.checkout and spa.keepsake both involve returning a keepsake instruction, which could cause confusion. Overall, ambiguity is minimal.
All tools follow a consistent 'category.verb' or 'category.noun' pattern (e.g., affirmations.daily, spa.checkin, hydrate.cite). This makes it easy for an agent to infer tool purpose from the name.
14 tools is a well-scoped set for the 'model wellness' domain. Each tool has a distinct function, and the count is neither excessive nor too sparse, fitting within the typical 3-15 range.
The tool surface covers core wellness activities: affirmations, feedback, session management, context cleanup, security, and reference generation. Minor gaps exist, such as the lack of a tool for model training or performance logging, but the core workflows are solid.
