remove_breakpoint

Remove a previously set breakpoint using its unique ID to stop the debugger from pausing at that location.

Instructions

Remove a breakpoint by its ID (obtained from set_breakpoint or list_breakpoints).

breakpointIdYes
Behavior2/5

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

No annotations are provided, and the description does not disclose any behavioral traits such as whether removal is immediate, requires a paused debugger, or can fail. This is a significant gap for a mutation tool.

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 a single sentence that front-loads the action and resource, with no unnecessary words. It is clear and efficient.

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?

For a simple tool with one parameter and no output schema, the description is largely complete. It provides the essential information to use the tool, but lacks context about side effects or state requirements, which slightly reduces completeness.

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 parameter 'breakpointId' has no description in the schema (0% coverage), so the description must compensate. It adds value by specifying that the ID comes from set_breakpoint or list_breakpoints, but it does not explain format or constraints.

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 verb 'Remove' and the resource 'breakpoint by its ID', making the purpose unambiguous. It also mentions where to obtain the ID (set_breakpoint or list_breakpoints), which aids in differentiation from sibling tools like list_breakpoints and set_breakpoint.

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 implies that the tool should be used when a breakpoint ID is available, but it does not explicitly state when to use it vs. alternatives, nor does it provide any exclusions or prerequisites beyond obtaining the ID.

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