get_game_state

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

No annotations are provided, so the description carries the full burden. It does not disclose side effects (e.g., taking a screenshot by default), permissions, or what 'analysis' entails (e.g., parsing screen, reading stats). The parameter description for fresh_screenshot mentions screenshot behavior, but the main description lacks these details.

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 that front-loads the core purpose. However, it could be slightly more structured by separating the tool's action from its scope. It is concise but not perfectly efficient, earning a 4.

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 has no output schema, the description should explain what the returned 'analysis' contains. It only says 'comprehensive analysis' without listing components (e.g., stats, inventory, screen regions). With one parameter fully described, the description is still incomplete for an agent to understand the tool's output.

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 coverage is 100% as the only parameter (fresh_screenshot) is fully described in the schema. The description adds no additional meaning beyond the schema for this parameter, so baseline 3 is appropriate.

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 'Get a comprehensive analysis of the current game state (all elements in one call)' uses a specific verb ('Get') and resource ('comprehensive analysis of the current game state'), and explicitly distinguishes from sibling tools by promising 'all elements in one call', which is unique among the specific analyzers and detectors.

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 description implies use when a full state overview is needed, but it does not explicitly state when to prefer this over sibling tools like get_inventory or get_stats, nor does it mention when not to use it (e.g., if only a subset is needed for efficiency).

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