save_game_state

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

No annotations are present, so the description must fully disclose behavior. It indicates a write operation but omits important details such as whether saves overwrite existing slots, require specific permissions, or are undoable. The agent lacks awareness of side effects or constraints beyond the schema.

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, front-loaded sentence that efficiently conveys the tool's core function with no extraneous words. Every part earns its place.

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 save operation with two parameters and no output schema, the description covers the basic function but lacks completeness. It does not explain what happens on overwrite, how errors are reported, or what the return value indicates. This is a moderate gap given the absence of an output schema.

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% with descriptions for both parameters. The description adds minimal value beyond the schema, only restating that metadata is optional. It does not explain the purpose of slots or the structure of metadata, so it meets the baseline for high schema coverage.

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 action ('Save'), the resource ('current game state'), and the destination ('numbered slot with optional metadata'). It distinguishes the tool from siblings like 'load_game_state' and 'delete_save_file' by specifying the saving function.

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 usage guidance is provided. The description does not mention when to use this tool versus other save-related siblings (e.g., 'compare_save_states', 'list_save_files'). No alternatives or exclusions are given, leaving the agent to infer context from the tool name alone.

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