game_key_press

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

With no annotations beyond the title, the description has full responsibility for behavioral disclosure. It only states the basic action, omitting details like auto-release (documented in schema parameter description), side effects, or required game state. For a safe mutation tool, this is insufficient.

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 a single sentence, concise and front-loaded. However, it is too minimal to be fully helpful; every word earns its place, but it lacks necessary detail for effective use.

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 60+ sibling tools including many input-related ones, the description fails to provide context. With 3 optional params, no output schema, and no annotations, it should clarify parameter relationships and when to use alternative tools. It is incomplete.

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%, so baseline is 3. The description does not add meaning beyond the schema, e.g., explaining when to use 'key' vs 'action' or the effect of 'pressed'. It stays at baseline.

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 sends a key press or input action, but does not explicitly differentiate from siblings like game_key_hold or game_key_release, which involve different durations. The verb 'press' implies momentary action, but the inclusion of 'input action' covers a broader category.

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 guidance on when to use this tool versus alternatives. For example, game_key_hold is for sustained presses, game_key_release for releases, and game_click for mouse clicks. The description lacks context for choosing among these.

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