game_key_release

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

The description is too brief and does not disclose behavioral traits beyond the obvious. For example, it doesn't state whether releasing an unheld key has no effect, produces an error, or requires the key to be currently held. With no annotations, the description carries the full burden and fails to provide necessary context.

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 extremely concise—only four words—with no unnecessary information. It is front-loaded and efficient.

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 tool's simplicity (no required parameters, no output schema, no annotations), the description is minimally adequate. However, for a tool that pairs with 'game_key_hold', additional context about typical usage or prerequisites would improve completeness.

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 100% (key and action parameters are described in the schema). The description adds no additional meaning beyond what the schema already provides. A score of 3 is appropriate as the schema does the heavy lifting.

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 'Release a previously held key' is specific and clear. It uses a verb ('release') and a resource ('key'), and it distinguishes itself from sibling tools like 'game_key_hold' and 'game_key_press' by indicating the opposite action.

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 is provided on when to use this tool versus alternatives. It is implied that it should be used after a key has been held, but there is no mention of pairing with 'game_key_hold' or conditions under which release is appropriate.

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