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

No annotations are supplied, so the description carries the full disclosure burden. It does not say what happens if the hand is empty, if the station is occupied, whether the release is reversible or atomic, or whether a result is returned; only the 'empty station' phrase hints at a precondition.

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 filler, and the operative constraint ('empty station') lands early. Its terseness is a size problem, but that failure belongs to completeness rather than to structure.

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 two-parameter manipulation tool with zero annotation coverage, no output schema, and no parameter documentation, the description leaves the agent without hand-naming conventions, station semantics, or failure behavior. The little it says about preconditions is not enough to invoke the tool reliably.

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%: 'hand' is a bare string and 'station' a bare integer with no documented format. The description mentions a station in passing but never explains its indexing or addressing, and never mentions 'hand' at all (whether it is a name, side, or identifier), so it fails to compensate for the coverage gap.

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 concrete action (release a held object) and its destination (an empty station), which makes the effect clear. It implies the inverse relationship with 'pick' but never names that sibling, so the agent must infer the pairing from the tool list.

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?

'Held object' and 'empty station' embed two prerequisites – something must already be grasped and the target must be free – which is useful implied guidance. However, there is no explicit when-to-use framing and no mention of the alternative sibling 'move_object', which plausibly competes for the same intent.

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