halt

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

No annotations are provided, so the description must disclose all behavioral traits. It states execution is suspended and lists post-halt capabilities, but omits potential side effects (e.g., impact on timers, interrupts) or requirements (e.g., target state). The return value is mentioned, which helps.

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 two sentences, front-loaded with the primary action, and includes necessary details about post-halt operations and return value. No wasted words.

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 parameterless tool with an output schema, the description covers the main behavior and return value. However, it lacks contextual prerequisites (e.g., must be connected, target status) and does not mention if it can be called repeatedly or safety concerns.

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?

The input schema has no parameters (coverage 100%), so the description does not need to explain any. The baseline is 4, and the description adds no redundancy, staying clear and concise.

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 explicitly states the tool suspends CPU execution, and lists what actions are possible afterward (read/write memory, registers, single step). This clearly identifies the action and resource, distinguishing it from siblings like 'run' or 'reset'.

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 usage when you need to pause the CPU, but does not explicitly state when to use it versus alternatives, nor does it provide exclusions or prerequisites (e.g., must be connected).

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