execution_control

Control program execution by resuming, pausing, single-stepping into/over calls, tracing N instructions, or running to a target address. Use run_to for one-shot stops that auto-clean breakpoints.

Instructions

Control execution: run, pause, single-step, run-to-address. TIP: Use 'run_to' instead of breakpoint(action='set')+run for one-shot stops (auto-cleans the BP).

Behavior3/5

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 discloses one useful behavioral trait: run_to 'auto-cleans the BP'. However, it does not mention other potential side effects, whether commands block, or what happens to the debuggee state on pause/resume. This is only partial transparency.

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?

The description is two sentences: a compact list of actions followed by a focused tip. Both sentences provide distinct value, and the core purpose is front-loaded. There is no fluff or redundancy.

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

Completeness4/5

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

The schematic descriptions and output schema already cover most operational details, so the description need not repeat them. The description provides the core purpose and a useful tip, but it omits any statement about how it relates to the swarm of sibling debugger tools or general side effects. Overall, it is reasonably complete for a well-schema'd tool.

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

Parameters3/5

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

The input schema covers 100% of parameters with detailed descriptions, including enums, defaults, and examples. The tool description adds little beyond the schema, except for the auto-clean tip, which relates to action behavior rather than parameter meaning. Baseline 3 is appropriate given the schema coverage.

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

Purpose4/5

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

The description clearly states the tool's function: 'Control execution: run, pause, single-step, run-to-address.' This specifies the verb and resource and enumerates the main actions. However, it does not explicitly distinguish this tool from the many sibling debugger control tools (e.g., windbg_continue, windbg_step_in), so it falls short of a 5.

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

Usage Guidelines4/5

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

The description provides an explicit alternative: 'Use run_to instead of breakpoint(action='set')+run for one-shot stops (auto-cleans the BP).' This gives a concrete when-to-use recommendation that references another tool. Broader guidance on when to prefer this tool over sibling tools is absent, but the tip is a valuable usage guideline.

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