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

Since no annotations are provided, the description carries the full behavioral burden. It discloses one useful trait: the tool is non-blocking and operates on the current state only, not waiting for a new pick. It does not however state whether calling it mutates anything, what happens when no pick exists yet, or what exactly is returned, so transparency is adequate but incomplete.

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 very short, front-loaded with the main purpose, and every phrase earns its place. The first sentence states the resource; the second gives the decisive behavioral contrast of not waiting and seeing only current state. There is no filler or redundant restatement.

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 getter, the description is mostly sufficient and the no-wait behavior is important context. But there is no output schema, and the description does not clarify what the returned value looks like or what the tool does when no pick has occurred. Those gaps matter for an AI agent deciding how to use the result or how to handle an empty state.

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?

The tool takes zero parameters, so the input schema carries little meaning. With 0 params, the baseline is 4, and the description does not need to compensate for parameter documentation. Nothing about parameters is missing or ambiguous.

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 identifies a specific resource, '가장 최근에 짚은 곳' (the most recently picked place), and gives the essential verb concept of '본다' (looks/retrieves what is currently there). It also differentiates itself from wait_for_pick by emphasizing '기다리지 않고', so the purpose is clear. It stops short of 5 because 'pick' is never explicitly defined and the retrieval verb is somewhat vague.

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?

The phrase '기다리지 않고 지금 있는 것만 본다' gives the agent a clear usage context: use this when the current, latest picked value is wanted immediately, without waiting for a future pick. This also contrasts naturally with the sibling wait_for_pick. However, the description does not explicitly name alternatives like list_picks or explain when not to use it, so it misses a 5.

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