BizHawk Emulator MCP

emulator_load_baseline

Load a named baseline save state from the runtime target's states directory, restoring the emulator to a pre-configured starting point for consistent test runs.

Instructions

Behavior2/5

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It reveals the location (runtime/<target>/states) but provides no information about side effects, whether emulation state is altered, whether the emulator must be running, permissions needed, or what happens on failure. The 'alias' framing is itself cryptic—an alias of what?

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence that directly states the action and location. While under-specified in content, it is efficiently written with no wasted words or filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has 0% schema coverage, no annotations, and no output schema, the description must do substantially more to be complete. It fails to explain how baselines differ from save states, what the load behavior entails, error conditions, or how it relates to emulator_load_state and bizhawk_load_baseline. The 'alias' label suggests deeper underlying behavior that is left undocumented.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, and the description does not explain either parameter meaningfully. 'name' (default 'baseline') and 'target' (default 'gb') are self-evident from their names and defaults, but the description's mention of runtime/<target>/states only partially clarifies how 'target' maps to a directory. The description adds minimal value over the raw schema for parameter understanding.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states it loads a named baseline state from runtime/<target>/states, which identifies the verb (load) and resource (baseline). However, it self-identifies as an 'Alias', creating ambiguity about how it differs from sibling tools like emulator_load_state and bizhawk_load_baseline. The purpose is clear enough but the alias framing and lack of differentiation from emulator_load_state undermines clarity.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given on when to use this tool versus emulator_load_state, emulator_create_baseline, or bizhawk_load_baseline. An agent would not know whether to call this or emulator_load_state to restore a saved state, nor how baselines differ from saved states. The description offers no context for discriminating between the many sibling emulator tools.

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