reset_machine

Resets the emulated ZX Spectrum machine. Choose a soft CPU reset or a hard reset to recover from crashes or reinitialize the system.

Instructions

Reset the emulated machine. Soft reset sends ZRCP "reset-cpu"; hard reset sends "hard-reset-cpu".

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
hard_resetNoPerform a hard reset ("hard-reset-cpu") instead of a soft CPU reset ("reset-cpu").
Behavior2/5

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 only mentions the commands sent but omits side effects such as state of registers, memory, or breakpoints after reset. The behavioral disclosure is incomplete.

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

Conciseness5/5

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

Two sentences, no extraneous information. The purpose is front-loaded and every word serves a purpose.

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

Completeness3/5

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

For a simple tool with one parameter and no output schema, the description is minimally adequate. However, it lacks context on the post-reset state (e.g., machine initialized, execution stopped). Could be more complete for a reset operation.

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

Parameters4/5

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

The schema covers the single boolean parameter with 100% coverage. The description adds value by naming the specific ZRCP commands for each reset type, providing semantic context beyond the schema's description.

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

Purpose5/5

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

The description clearly states it resets the emulated machine and distinguishes between soft and hard reset by specifying the ZRCP commands sent. This sets it apart from siblings like cpu_step which operate at a finer granularity.

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

Usage Guidelines3/5

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

The description explains what each reset type does but does not provide guidance on when to choose soft vs hard reset, nor does it exclude alternative tools. Usage context is implied but not explicit.

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